7 material design css фреймворков на 2017 год

Transform, manipulate, and read your data

Once you’ve got the data in, define views and perform reads via the PostgreSQL protocol. Use your favorite PostgreSQL CLI, including the you probably already have on your system.


Materialize supports a comprehensive variety of SQL features, all using the PostgreSQL dialect and protocol:

  • Joins, Joins, Joins! Materialize supports multi-column join conditions, multi-way joins, self-joins, cross-joins, inner joins, outer joins, etc.
  • Delta-joins avoid intermediate state blowup compared to systems that can only plan nested binary joins — tested on joins of up to 64 relations.
  • Support for subqueries. Materialize’s SQL optimizer performs subquery decorrelation out-of-the-box, avoiding the need to manually rewrite subqueries into joins.
  • All the aggregations. , , , , , , , etc.
  • JSON support in the PostgreSQL dialect including operators and functions like , , , , , . Materialize automatically plans lateral joins for efficient support.
  • Nest views on views on views!
  • Multiple views that have overlapping subplans can share underlying indices for space and compute efficiency, so just declaratively define what you want, and we’ll worry about how to efficiently maintain them.

Just show us what it can do!

Here’s an example join query that works fine in Materialize, query 15:

-- Views define commonly reused subqueries.
CREATE VIEW revenue (supplier_no, total_revenue) AS
    SELECT
        l_suppkey,
        SUM(l_extendedprice * (1 - l_discount))
    FROM
        lineitem
    WHERE
        l_shipdate >= DATE '1996-01-01'
        AND l_shipdate < DATE '1996-01-01' + INTERVAL '3' month
    GROUP BY
        l_suppkey;

-- Materialized views are maintained automatically, and can depend on non-materialized views.
CREATE MATERIALIZED VIEW tpch_q15 AS
  SELECT
    s_suppkey,
    s_name,
    s_address,
    s_phone,
    total_revenue
FROM
    supplier,
    revenue
WHERE
    s_suppkey = supplier_no
    AND total_revenue = (
        SELECT
            max(total_revenue)
        FROM
            revenue
    )
ORDER BY
    s_suppkey

Stream inserts, updates, and deletes on the underlying tables ( and ), and Materialize keeps the materialized view incrementally updated. You can type and expect to see the current results immediately!

How does it compare to existing Material CSS implementations?

Materialize, Material Bootstrap, etc

We think the community does a great job offering their own take on how Material Design should be implemented for CSS libraries.

That said, the large, diverse number of implementations available are often quite liberal with their interpretation of the spec (not their fault!) and their opinions don’t always reflect what the Material Design team would consider ‘correct’. MDL was developed in close collaboration with the Material Design and Chrome UX teams and undergoes regular reviews for spec compliance. When we run into an area of the spec that isn’t yet fully fleshed out, MDL is able to offer reviewed opinions on how these should be solved in a way that tries to stay true to Material Design.

Which browsers does MDL support?

The complete MDL experience should work in the last two versions of all evergreen browsers, whilst we gracefully degrade to CSS-only in browsers like IE9 that don’t pass our test.

Our has the most up to date information on the browsers we officially support. For components, at minimum we require support for querySelector, classList and addEventListener, which can be polyfilled as needed. Our Templates will work in IE10+, primarily due to our use of Flexbox.

The polyfills that we’re currently using for the MDL site to improve support in oldIE are the following:

IE10 standards mode removes support for conditional comments, so the above will only get interpreted by older versions of IE, such as IE9.

We do not officially support IE8. That said, some components will degrade using the CSS-only (or native HTML element) experience there better than others. For example:

Buttons

Tables

Sliders (degrade to input fields)

Example

The following figure shows an example of using the Materialized View pattern to generate a summary of sales. Data in the Order, OrderItem, and Customer tables in separate partitions in an Azure storage account are combined to generate a view containing the total sales value for each product in the Electronics category, along with a count of the number of customers who made purchases of each item.

Creating this materialized view requires complex queries. However, by exposing the query result as a materialized view, users can easily obtain the results and use them directly or incorporate them in another query. The view is likely to be used in a reporting system or dashboard, and can be updated on a scheduled basis such as weekly.

Installation

1. Download: Download Materialize — Free from Github or visit and download the latest release.

2. Github

  • Fork the repository (here is the guide).
  • Clone to your machine

Grunt

Run npm install command to install required node modules

Running Grunt Dist Commands

Except Grunt dist-js command you must have to pass Layout = «{{theme-name}}» parameter to let grunt know compile theme specific scss files. Generic syntax for grunt command is

Where task will be name of grunt task and theme-name will the theme you wish to compile scss for it.

Task Command Description
Dist To clean css, js and build distributable css and js files
Monitor Watch all scss files change and compile it accordingly. In this command you need to pass the Layout parameater in grunt commands
Build JS To clean js files and build distributable js files
Compile SCSS Compile scss files
Build CSS To clean css files and build distributable css files

When to use this pattern

This pattern is useful when:

  • Creating materialized views over data that’s difficult to query directly, or where queries must be very complex to extract data that’s stored in a normalized, semi-structured, or unstructured way.
  • Creating temporary views that can dramatically improve query performance, or can act directly as source views or data transfer objects for the UI, for reporting, or for display.
  • Supporting occasionally connected or disconnected scenarios where connection to the data store isn’t always available. The view can be cached locally in this case.
  • Simplifying queries and exposing data for experimentation in a way that doesn’t require knowledge of the source data format. For example, by joining different tables in one or more databases, or one or more domains in NoSQL stores, and then formatting the data to fit its eventual use.
  • Providing access to specific subsets of the source data that, for security or privacy reasons, shouldn’t be generally accessible, open to modification, or fully exposed to users.
  • Bridging different data stores, to take advantage of their individual capabilities. For example, using a cloud store that’s efficient for writing as the reference data store, and a relational database that offers good query and read performance to hold the materialized views.

This pattern isn’t useful in the following situations:

  • The source data is simple and easy to query.
  • The source data changes very quickly, or can be accessed without using a view. In these cases, you should avoid the processing overhead of creating views.
  • Consistency is a high priority. The views might not always be fully consistent with the original data.
  • When using microservices. Microservices typically have well defined boundries aligning to domain driven design (DDD).

Установка фреймворка

На вкладке Get Started вы увидите несколько вариантов установки:

Вариант #1). Скачать архив с CSS и JS файлами, указать пути к этим файлам на HTML странице. Кроме того необходимо добавить ссылки на шрифтовые иконки и библиотеку JQuery.

Вариант #2). Вы подключаете те же самые файлы, только через CDN. Если вам не нужно, чтобы файлы находились физически в самом проекте, то просто вставьте этот код в HTML документ. И не забудьте про иконки и библиотеку JQuery.

Вариант #3). Через пакетный менеджер NPM, введите в командную строку следующий код, предварительно перейдя в папку проекта. Этот способ самый быстрый.

Фреймворк Materialize не является чем-то уникальным и по популярности сильно уступает Bootstrap. Но зато, в Materialize есть несколько интересных фишек, которые отличают его от других, а именно эффект Parallax, Scrollspy и Scrollfire (появление элементов по мере прокрутки страница).

Basic Usage:

Start a snackbar with a container div element. On that container define the and classes. It is also beneficial to add the aria live and atomic values to this container.

Within the container create a container element for the message. This element should have the class . Leave this element empty! Text is added when the snackbar is called to be shown.

Second in the container, add a button element. This element should have the class . It is recommended to set the type to button to make sure no forms get submitted by accident. Leave the text content empty here as well! Do not directly apply any event handlers.

You now have complete markup for the snackbar to function. All that is left is within your JavaScript to call the method on the snackbar container. This takes a to configure the snackbar content appropriately. You may call it multiple consecutive times and messages will stack.

What CSS naming conventions does MDL use?

MDL was written using BEM. BEM stands for Block, Element, Modifier. It is a method used to construct CSS class-names so they are consistent, isolated, and expressive. A few good resources for learning more about BEM methods are:

  • CSSWizardry
  • CSS-Tricks
  • Smashing Magazine

These are great resources that simplify the data needed to understand BEM. If you want to read the methodology from the inventors, Yandex provides the resource. This reference goes way beyond just the CSS and into the full JavaScript setup they use as well.

Our wiki includes a section on the namespacing used for MDL specifically.

Configuration options

The MDL CSS classes apply various predefined visual enhancements to the tooltip. The table below lists the available classes and their effects.

MDL class Effect Remarks

Does MDL support progressive enhancement?

MDL’s components were designed from the ground up with progressive enhancement in mind. We attempt to build on native HTML elements as much as possible, relying on JavaScript where absolutely necessary for ‘enhancements’.

One example of this is our ‘Text only’ Material Design template. Switching JavaScript off in Chrome DevTools, the page still renders CSS fine:

This allows us to render important content first and then ‘enhance’ the page with things like Material Design button ripples and pop-out menu components.

MDL will degrade to a no-JavaScript experience on IE9, though you can pull in polyfills for an enhanced experience. If components require JavaScript to function, such as Layout, these will otherwise need to be planned for in development. IE10+ and evergreen browsers are fully supported. For more details on our browser support, see ‘Which browsers does MDL support?’.

Note: the MDL site itself attempts to use progressive enhancement where possible. We do however have aspects of the site (e.g our component page) that rely more heavily on JS. The MDL Templates and Components otherwise try to render as well as they can with JS off.

Basic Usage

To use the dialog component, you must be using a browser that supports the . Only Chrome and Opera have native support at the time of writing. For other browsers you will need to include the dialog polyfill or create your own.

Once you have dialog support create a dialog element. The element when using the polyfill must be a child of the element. Within that container, add a content element with the class . Add you content, then create an action container with the class . Finally for the markup, add your buttons within this container for triggering dialog functions.

Keep in mind, the order is automatically reversed for actions. Material Design requires that the primary (confirmation) action be displayed last. So, the first action you create will appear last on the action bar. This allows for more natural coding and tab ordering while following the specification.

Remember to add the event handlers for your action items. After your dialog markup is created, add the event listeners to the page to trigger the dialog to show.

For example:

Solution

To support efficient querying, a common solution is to generate, in advance, a view that materializes the data in a format suited to the required results set. The Materialized View pattern describes generating prepopulated views of data in environments where the source data isn’t in a suitable format for querying, where generating a suitable query is difficult, or where query performance is poor due to the nature of the data or the data store.

These materialized views, which only contain data required by a query, allow applications to quickly obtain the information they need. In addition to joining tables or combining data entities, materialized views can include the current values of calculated columns or data items, the results of combining values or executing transformations on the data items, and values specified as part of the query. A materialized view can even be optimized for just a single query.

A key point is that a materialized view and the data it contains is completely disposable because it can be entirely rebuilt from the source data stores. A materialized view is never updated directly by an application, and so it’s a specialized cache.


When the source data for the view changes, the view must be updated to include the new information. You can schedule this to happen automatically, or when the system detects a change to the original data. In some cases it might be necessary to regenerate the view manually. The figure shows an example of how the Materialized View pattern might be used.

Что такое material design

CSS стили поддерживают принципы популярного направления в веб-дизайне — material design, когда-то разработанного компанией . Самый ближайший дизайн с которыми часто сравнивают material design, это flat design (плоский дизайн). Плоский дизайн старается сфокусировать вас на легком взаимодействие с сайтом и позволяет упростить его функциональность

А также подчеркивает важность контента, выделяя его на странице. Часто материальный дизайн делают в стиле минимализма, с минимальным набором элементов дизайна

Бывает так, что иконки и логотип — единственные нефункциональные элементы на странице. Никакого глянца и глубоких теней на кнопках быть не должно.

На сайте material.io вы можете найти все основные правила материального дизайна вместе с наглядными примерами.

Issues and considerations

Consider the following points when deciding how to implement this pattern:

How and when the view will be updated. Ideally it’ll regenerate in response to an event indicating a change to the source data, although this can lead to excessive overhead if the source data changes rapidly. Alternatively, consider using a scheduled task, an external trigger, or a manual action to regenerate the view.

In some systems, such as when using the Event Sourcing pattern to maintain a store of only the events that modified the data, materialized views are necessary. Prepopulating views by examining all events to determine the current state might be the only way to obtain information from the event store. If you’re not using Event Sourcing, you need to consider whether a materialized view is helpful or not. Materialized views tend to be specifically tailored to one, or a small number of queries. If many queries are used, materialized views can result in unacceptable storage capacity requirements and storage cost.

Consider the impact on data consistency when generating the view, and when updating the view if this occurs on a schedule. If the source data is changing at the point when the view is generated, the copy of the data in the view won’t be fully consistent with the original data.

Consider where you’ll store the view. The view doesn’t have to be located in the same store or partition as the original data. It can be a subset from a few different partitions combined.

A view can be rebuilt if lost. Because of that, if the view is transient and is only used to improve query performance by reflecting the current state of the data, or to improve scalability, it can be stored in a cache or in a less reliable location.

When defining a materialized view, maximize its value by adding data items or columns to it based on computation or transformation of existing data items, on values passed in the query, or on combinations of these values when appropriate.

Where the storage mechanism supports it, consider indexing the materialized view to further increase performance. Most relational databases support indexing for views, as do big data solutions based on Apache Hadoop.

Should I use the minified, CDN or Sass versions of MDL?

Should I build my own version or download the minified version or simply refer to CDN objects?

Minified: If it’s your first time using MDL, we recommend downloading one of the default packages from the ‘Getting Started’ page that include a minified version of our CSS/JS and optionally our pre-made Templates.

CDN: If you’re just prototyping or want to avoid hosting your own copy of the MDL CSS and JS files, you can use our CDN to pull down a heavily edge-cached version.

Customiser: If you’re creating a new site with MDL and are using a custom color scheme, we recommend downloading the default package then generating a custom build using the Customiser tool. You can use this to override the material.min.css file for your own needs.

Sass: If you would prefer to go all in, you can get the Sass version of MDL, which includes our original sources, docs and templates. This version allows maximum customisation using CSS variables and the rest of the Sass goodness you’re used to.

Can I build or use individual MDL components (e.g a button)?

For V1 of MDL we are focused on the use-case of folks who are likely to need a few different components on their page and will want to include most of the MDL library. This means that support and docs around just plucking single components on their own is minimal.

That said, if you need to generate a build using just a single (or smaller number of) components, you will need to use Gulp with our Sass build. You can comment out those components you don’t need in material-design-lite.scss, the scripts you don’t need in the Gulpfile and then run to create your build.

We have talked about offering up components in a more modular fashion but will be exploring this in the post V1 timeline.

Introduction


The Material Design Lite (MDL) tooltip component is an enhanced version of the standard HTML tooltip as produced by the attribute. A tooltip consists of text and/or an image that clearly communicates additional information about an element when the user hovers over or, in a touch-based UI, touches the element. The MDL tooltip component is pre-styled (colors, fonts, and other settings are contained in material.min.css) to provide a vivid, attractive visual element that displays related but typically non-essential content, e.g., a definition, clarification, or brief instruction.

Tooltips are a ubiquitous feature of most user interfaces, regardless of a site’s content or function. Their design and use is an important factor in the overall user experience. See the tooltip component’s Material Design specifications page for details.

To include an MDL tooltip component:

 1. Code an element, such as a , , or , and style it as desired; this will be the tooltip’s target. Include an attribute and unique value to link the container to its tooltip.

 2. Following the target element, code a second element, such as a , , or ; this will be the tooltip itself. Include a (or ) attribute whose value matches that of the target’s .

 3. Add one or more MDL classes, separated by spaces, to the tooltip element using the attribute.

The tooltip component is ready for use.

Examples

A target with a simple text tooltip.

A target with «rich» (containing HTML markup) tooltip text.

A target with a long text tooltip that automatically wraps.

A target with tooltip text in a larger font size.

A target with a tooltip containing both an image and text.

Where should I use Material Design Lite (MDL)?

If you’re interested in a Material Design experience using vanilla Web technologies like CSS, JavaScript and HTML, MDL might be a useful option to consider. We optimise for websites heavy on content, such as marketing pages, articles, blogs and general web content that isn’t particularly app-y. If you just want to pick some colors, customise a template and ship a Material experience, we try to help make that process simpler.

Whilst there exist several community-driven options for Material Design, our experience has shown that there are several gaps in the Material specification when it comes to the web. Rather than guessing how these gaps should be filled (something we know the community has struggled with), we’ve opted for a close collaboration with the Material Design team to provide a Material library that is both spec compatible for today and provides guidance on aspects of the spec still being evolved.

Context and problem

When storing data, the priority for developers and data administrators is often focused on how the data is stored, as opposed to how it’s read. The chosen storage format is usually closely related to the format of the data, requirements for managing data size and data integrity, and the kind of store in use. For example, when using NoSQL document store, the data is often represented as a series of aggregates, each containing all of the information for that entity.

However, this can have a negative effect on queries. When a query only needs a subset of the data from some entities, such as a summary of orders for several customers without all of the order details, it must extract all of the data for the relevant entities in order to obtain the required information.

Заключение

Практически невозможно определить победителя среди всех Material Design фреймворков. И разработчики могут сами выбирать те, которых больше остальных подходят под их требования. Это сравнимо с операционными системами — нет правильного или не правильного выбора, вы просто используете то, что удобнее, то, к чему привыкли.

Как бы то ни было, выбирая CSS фреймворк, вы должны учитывать следующее:

Сообщество: как много людей пользуются фреймворком? Большая пользовательская база значит не только то, что он хорошо протестирован, но и так же наличие поддержки пользователями в виде готовых шаблонов.

Разработчики: кто является разработчиком — компания или сообщество индивидуальных программистов? Частные дополнения кода, в том числе и исправление багов и принятые pull request’ы, важно чтобы были, заинтересованные в развитии проекта, стороны.

Развитие: Как часто выходят новые версии? Некоторые фреймворки обновляются постоянно, в то время как другие предпочитают идти более медленным темпом, в ногу с устоявшимися технологиями. Если вы хотите создавать прототипы и тестировать новые фичи, вероятнее всего вы выберете первое.

Документация: на сколько чиста и подробна официальная документация? Хорошая документация сильно помогает в использовании, особенно если это ваше первое знакомство с фреймворком

Готовые примеры позволяют разрабатывать очень быстро и не останавливаться на мелких загвоздках.

Обучаемость: Есть ли какие-то условия для использования? Если вам нужно быстро выпустить приложение в продакшн и нет времени экспериментировать с технологиями, с которыми вы ранее не работали, то вам лучше выбрать фреймворк, который не требует изучения нового синтаксиса и технологий для использования.

В качестве вывода можно сказать следующее: при выборе фреймворка или технологии руководствуйтесь вашими личным (или командным) опытом, предпочтениями и навыками, выбирайте тот, который больше всего подходит именно вам.
