Example

Imagine you have a file in your project with the following content:


.some-class{  // somestyles  &.someOtherClass {    // someotherstyles}  &-sayWhat {    // morestyles}}

Adding the will generate a file that has the following content:

exportinterfaceIMyComponentScss{'some-class'string;'someOtherClass'string;'some-class-sayWhat'string;}declareconststylesIMyComponentScss;exportdefaultstyles;

Using the as well as the options the generated file will look as follow:

exportconstsomeClassstring;exportconstsomeOtherClassstring;exportconstsomeClassSayWhatstring;

If you encounter the following errors:

maybe you should export the styles as following:

Well, the preloader background does not disappear after the content of the page has been loaded. Developer does not answer support requests on the support forum. So you’d better try a plugin where you can have support in case of problem.

Not sure what’s up with this plug in but when I added the code <div id=»wptime-plugin-preloader»></div> after <body> in header.php, the website died. Tried different locations in header.php file, but kills website mo matter where it is placed. ***PLUGIN DELETED***

Developers were responsive and helped me discover MY error quickly. Thanks.

One of the best preloader plugin, easy to setup, and ideally work, thank guys!

Installed it, followed all the instructions, but it didn’t work. Sent 2 requests for support but never received any reply. So after 2 weeks of waiting in vain I ended up deleting the plug-in and opting for EL Preloader. At least that one works!

How To Create a Loader

Step 1) Add HTML:

Example

<div class=»loader»></div>

Step 2) Add CSS:

Example

.loader {  border: 16px solid #f3f3f3; /* Light grey */  border-top: 16px solid #3498db; /* Blue */  border-radius: 50%;  width: 120px;  height: 120px;  animation: spin 2s linear infinite;}@keyframes spin {  0% { transform: rotate(0deg); }  100% { transform: rotate(360deg); }}

Example Explained

The property specifies the border size and the border color of the loader. The property transforms the loader into a circle.

The blue thing that spins around inside the border is specified with the property. You can also include , and/or if you want more «spinners» (see example below).

The size of the loader is specified with the and properties.

At last, we add an that makes the blue thing spin forever with a 2 second animation speed.

Note: You should also include a -webkit- prefix for browsers that do not support animation and transform properties. Click on the example to see how.

CircletPreloader jQuery Plugin

November 14, 2015 | HTML5, Plugins

CircletPreloader is a small jQuery plugin that for as circular loading animations show depict the state of charge of various HTML DOM elements as a percentage. The aim was to get along with as few KB, while flexibility as regards the possibilities for the representation of the loading animations. The minifie JavaScript file is only 2, 74 KB hard and needs no other and / or external JavaScript libraries. One can CircletPreloader even without jQuery use and is therefore completely independent. Using various parameters can be the loading animations individualize a large scale.

Getting Started

To begin, you’ll need to install :

npm install --save-dev css-loader

Then add the plugin to your config. For example:

file.js

importcssfrom'file.css';

webpack.config.js

module.exports={  module{    rules{        test\.css$,        use'style-loader','css-loader',},,},};

And run via your preferred method.

You can also use the css-loader results directly as a string, such as in Angular’s component style.

webpack.config.js

module.exports={  module{    rules{        test\.css$,        use'to-string-loader','css-loader',},,},};

or

constcss=require('./test.css').toString();console.log(css);

If there are SourceMaps, they will also be included in the result string.

webpack.config.js

module.exports={  module{    rules{        test\.css$,        use'handlebars-loader','extract-loader','css-loader',,},,},};

Прелоадер для сайта состоит из 4 частей:

  1. HTML-код прелоадера
  2. CSS стили оформления (которые отображают прелоадер поверх сайта и заслоняют им все содержимое)
  3. Java Script для его скрытия
  4. Картинка GIF (анимация прелоадера)

HTML-код прелоадера вставляется сразу после тега <body>.

<!— Прелоадер —> <div id=»before-load»> <i></i> </div> <!— /Прелоадер —>

1 2 3 4 5

<!—Прелоадер—>

<div id=»before-load»>

<i><i>

<div>

<!—Прелоадер—>

CSS-стиль оформления прелоадера можно вставить в секцию <head> или в файл стиля (я обычно его вставляю в самый верх, чтобы он в первую очередь загрузился, хотя не уверен, что раположение в файле стиля имеет значение).

<style> /* Прелоадер */ #before-load { position: fixed; left: 0; top: 0; right: 0; bottom: 0; background: #fff; z-index: 9999; } #before-load i { width: 70px; height: 70px; position: absolute; left: 50%; top: 50%; background: url(‘preloader.gif’) no-repeat 50% 50%; margin: -35px 0 0 -35px; } </style>

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

<style>

/* Прелоадер */

#before-load {

positionfixed;

left;

top;

right;

bottom;

background#fff;

z-index9999;

}

#before-load i {

width70px;

height70px;

positionabsolute;

left50%;

top50%;

backgroundurl(‘preloader.gif’)no-repeat50%50%;

margin-35px-35px;

}

</style>

Java Script для скрытия прелоадера надо разместить после вызова библиотеки JQuery. У меня он размещен перед закрывающимся тегом </body>.

<script src=»https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js»></script> <script> // Прелоадер $(window).load(function() { $(‘#before-load’).find(‘i’).fadeOut().end().delay(400).fadeOut(‘slow’); }); </script>

1 2 3 4 5 6 7

<script src=»https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js»></script>

<script>

// Прелоадер

$(window).load(function(){

$(‘#before-load’).find(‘i’).fadeOut().end().delay(400).fadeOut(‘slow’);

});

</script>

Фактически этот код просто после полной загрузки страницы сайта (вместе со всеми внешними скриптами и т.п.) включает плавную анимацию «затухания» прелоадера. Вот и вся магия.

Обратите внимание, используется JQuery анимация «затухания», поэтому нужна эта библиотека. Но т.к

JQuery сейчас везде используется, я не переживаю по этому поводу.

Ну и остается выбрать картинку прелоадера и положить его в нужное место (в стилях посмотрите, откуда он берется и там заодно можете его имя и адрес задать backgroundurl(‘preloader.gif’)no-repeat50%50%; ). Я не помню откуда этот взял, но скачать прелоадеры можно, например отсюда: http://preloaders.net, только проверьте внимательно какого он размера и этот размер укажите в стилях ( width70px;height70px; ).

Должно все заработать. Для полного понимания можно скачать рабочий пример прелоадера для сайта.

С прелоадерами все красиво и прикольно, пока не начинается затуп какого-нибудь скрипта, который берется с другого сайта/сервера. Тогда прелоадер может зависнуть на очень продолжительный срок. Посетитель, ясное дело, решит что ваш сайт говно нерабочее и свалит к конкуренту за нужным контентом. Например, я сталкивался с такими затупами по вине виджета группы вконтакте, рекламы гугл адсенса и адривера. В общем, все это нифига не надежно, если сайт что-то подгружает со сторонних серверов.

А учитывая, что сам Гугл где-то писал, что задержка загрузки сайта свыше 5 секунд приводит к катастрофическому количеству отказов, что очень плохо повлияет на поведенческий фактор. Да и вообще каждая дополнительная секунда ожидания уменьшает лояльность пользователя. Поэтому там где такие затупы прелоадера вполне реальны я использую код JS с фиксом.

<script src=»https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js»></script> <script> setTimeout(function() { $(‘#before-load’).find(‘i’).fadeOut().end().delay(400).fadeOut(‘slow’); }, 1000); // Прелоадер $(window).load(function() { $(‘#before-load’).find(‘i’).fadeOut().end().delay(400).fadeOut(‘slow’); }); </script>

1 2 3 4 5 6 7 8

<script src=»https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js»></script>

<script>

setTimeout(function(){$(‘#before-load’).find(‘i’).fadeOut().end().delay(400).fadeOut(‘slow’);},1000);

// Прелоадер

$(window).load(function(){

$(‘#before-load’).find(‘i’).fadeOut().end().delay(400).fadeOut(‘slow’);

});

</script>

Т.е. если страница не успела за секунду загрузиться, то все равно прелоадер убрать (На самом деле получается около 2 сек., т.к. пока код загрузится, потом он только отработает отчет секунды, а потом еще анимация затухания около полусекунды).

jPreLoader : jQuery Preloading Screen to Preload Images

July 26, 2012 | Plugins, Web

Today I would like to share with you a brand new jQuery plugin, called jPreLoader. jPreLoadercan create a preloading screen for your website before all your images (including the images in CSS) are fully loaded. It will come in handy when you wish to preload all the images on your page before exposed to user. It’s useful for those games websites.


Well, you can also create a Splash Screen during preloading process to introduce your products, or describe about your page, or show the instructions of gameplay as well as put an advertisement during the waiting time of your user.

Examples

webpack.config.js

module.exports={  module{    rules{        test\.css$i,        use'style-loader','css-loader',},{        test\.(png|jpe?g|gif|svg|eot|ttf|woff|woff2)$i,        loader'url-loader',        options{          limit8192,},},,},};

For production builds it’s recommended to extract the CSS from your bundle being able to use parallel loading of CSS/JS resources later on.

When you have pure CSS (without CSS modules) and CSS modules in project you can use this setup:

webpack.config.js

module.exports={  module{    rules{        test\.css$i,        exclude\.module\.css$i,        use'style-loader','css-loader',},{        test\.module\.css$i,        use'style-loader',{            loader'css-loader',            options{              modulestrue,},},,},{        test\.(png|jpe?g|gif|svg|eot|ttf|woff|woff2)$i,        loader'url-loader',        options{          limit8192,},},,},};

component.js

webpack.config.js

Type: Default:

By default, the appends / elements to the end of the style target, which is the tag of the page unless specified by . This will cause CSS created by the loader to take priority over CSS already present in the target. You can use other values if the standard behavior is not suitable for you, but we do not recommend doing this. If you target an iframe make sure you have sufficient access rights, the styles will be injected into the content document head.

Allows to setup custom query selector where styles inject into the DOM.

webpack.config.js

A new / elements will be inserted into at bottom of tag.

Allows to override default behavior and insert styles at any position.

webpack.config.js

Insert styles at top of tag.

This setting is primarily used as a workaround for css clashes when using one or more DllPlugin’s. allows you to prevent either the app’s css (or DllPlugin2’s css) from overwriting DllPlugin1’s css by specifying a css module id base which is greater than the range used by DllPlugin1 e.g.:

webpack.dll1.config.js

webpack.dll2.config.js

webpack.app.config.js

Type: Default:

By default, generates JS modules that use the CommonJS modules syntax. There are some cases in which using ES modules is beneficial, like in the case of module concatenation and tree shaking.

You can enable a ES module syntax using:

webpack.config.js

Examples

webpack.config.js

module.exports={  module{    rules{        test\.css$,        use'style-loader','css-loader'},{        test\.(png|jpg|gif|svg|eot|ttf|woff|woff2)$,        loader'url-loader',        options{          limit10000}}}}

webpack.config.js

constenv=process.env.NODE_ENVconstExtractTextPlugin=require('extract-text-webpack-plugin')module.exports={  module{    rules{        test\.css$,        use env ==='production'?ExtractTextPlugin.extract({              fallback'style-loader',              use'css-loader'})'style-loader','css-loader'},},  plugins env ==='production'?newExtractTextPlugin({          filename'.css'})}

Getting Started

To begin, you’ll need to install :

npm install --save-dev css-loader

Then add the plugin to your config. For example:

file.js

importcssfrom'file.css';

webpack.config.js

module.exports={  module{    rules{        test\.css$i,        use'style-loader','css-loader',},,},};

And run via your preferred method.

You can also use the css-loader results directly as a string, such as in Angular’s component style.

webpack.config.js

module.exports={  module{    rules{        test\.css$i,        use'to-string-loader','css-loader',},,},};

or

constcss=require('./test.css').toString();console.log(css);

If there are SourceMaps, they will also be included in the result string.

webpack.config.js

module.exports={  module{    rules{        test\.css$i,        use'handlebars-loader','extract-loader','css-loader',,},,},};

Options

Just like any other loader you can specify options e.g. as query-params

Any option that your installed version of css-loader supports can be used and will be passed to it.

As your fellow css-developer may tend to use characters like dashes() that are not valid characters for a typescript variable the default behaviour for this loader is to export an interface as the default export that contains the classnames as properties. e.g.:

exportinterfaceIExampleCss{'foo'string;'bar-baz'string;}declareconststylesIExampleCss;exportdefaultstyles;

A cleaner way is to expose all classes as named exports, this can be done if you enable the -option. e.g.

{ test\.css$, loader'typings-for-css-modules?modules&namedExport'}

As mentioned above, this requires classnames to only contain valid typescript characters, thus filtering out all classnames that do not match /^\w+$/i. (feel free to improve that regexp) In order to make sure that even classnames with non-legal characters are used it is highly recommended to use the -option as well, that — once passed to the css-loader — makes sure all classnames are transformed to valid variables. with:

{ test\.css$, loader'typings-for-css-modules?modules&namedExport&camelCase'}

using the following css:

.foo{colorwhite;}.bar-baz{colorgreen;}

will generate the following typings file:

exportconstfoostring;exportconstbarBazstring;

exports mappings to which is incompatible with the -option unless paired with or . They move the exported properties from to making them required for to work, and required for them to work. Always combine usage of or with the -option.

To silence the loader because you get annoyed by its warnings or for other reasons, you can simply pass the «silent» query to the loader and it will shut up. e.g.:

{ test\.css$, loader'typings-for-css-modules?silent'}

To add a «banner» prefix to each generated file, you can pass a string to this option as shown below. The prefix is quite literally prefixed into the generated file, so please ensure it conforms to the type definition syntax.

{ test\.css$, loader'typings-for-css-modules?banner="// This file is automatically generated by typings-for-css-modules.\n// Please do not change this file!"'}

Getting Started

To begin, you’ll need to install :

npm install --save-dev css-loader

Then add the plugin to your config. For example:


file.js

importcssfrom'file.css';

webpack.config.js

module.exports={  module{    rules{        test\.css$i,        use'style-loader','css-loader',},,},};

And run via your preferred method.

You can also use the css-loader results directly as a string, such as in Angular’s component style.

webpack.config.js

module.exports={  module{    rules{        test\.css$i,        use'to-string-loader','css-loader',},,},};

or

constcss=require('./test.css').toString();console.log(css);

If there are SourceMaps, they will also be included in the result string.

webpack.config.js

module.exports={  module{    rules{        test\.css$i,        use'handlebars-loader','extract-loader','css-loader',,},,},};

Examples

The loader automatically inject source maps when previous loader emit them. Therefore, to generate source maps, set the option to for the previous loader.

webpack.config.js

module.exports={  module{    rules{        test\.css$i,        use'style-loader',{ loader'css-loader', options{ sourceMaptrue}},,},,},};

There are two ways to work with :

  • using the option
  • using the variable

component.js

import'./style.css';

webpack.config.js

module.exports={  module{    rules{        test\.css$i,        use{            loader'style-loader',            options{              attributes{                nonce'12345678',},},},'css-loader',,},,},};

The loader generate:

<stylenonce="12345678">.foo{colorred;}</style>

create-nonce.js

__webpack_nonce__ ='12345678';

component.js

import'./create-nonce.js';import'./style.css';

Alternative example for :

component.js

__webpack_nonce__ ='12345678';require('./style.css');

webpack.config.js

module.exports={  module{    rules{        test\.css$i,        use'style-loader','css-loader',},,},};

The loader generate:

<stylenonce="12345678">.foo{colorred;}</style>

Inserts styles at top of tag.

webpack.config.js

module.exports={  module{    rules{        test\.css$i,        use{            loader'style-loader',            options{insertfunctioninsertAtTop(element){var parent =document.querySelector('head');var lastInsertedElement =window._lastElementInsertedByStyleLoader;if(!lastInsertedElement){parent.insertBefore(element,parent.firstChild);}elseif(lastInsertedElement.nextSibling){parent.insertBefore(element,lastInsertedElement.nextSibling);}else{parent.appendChild(element);}window._lastElementInsertedByStyleLoader= element;},},},'css-loader',,},,},};

Inserts styles before element.

webpack.config.js

module.exports={  module{    rules{        test\.css$i,        use{            loader'style-loader',            options{insertfunctioninsertBeforeAt(element){constparent=document.querySelector('head');consttarget=document.querySelector('#id');constlastInsertedElement=window._lastElementInsertedByStyleLoader;if(!lastInsertedElement){parent.insertBefore(element, target);}elseif(lastInsertedElement.nextSibling){parent.insertBefore(element,lastInsertedElement.nextSibling);}else{parent.appendChild(element);}window._lastElementInsertedByStyleLoader= element;},},},'css-loader',,},,},};

Usage

The interprets and like and will resolve them.

file.js

importcssfrom'file.css';

webpack.config.js

module.exports={  module{    rules{        test\.css$,        use'style-loader','css-loader'}}}

You can also use the css-loader results directly as string, such as in Angular’s component style.

webpack.config.js

{   test\.css$,   use'to-string-loader','css-loader'}

or

constcss=require('./test.css').toString();console.log(css);

If there are SourceMaps, they will also be included in the result string.

webpack.config.js

{   test\.css$,   use'handlebars-loader','extract-loader','css-loader'}

Examples

webpack.config.js

module.exports={  module{    rules{        test\.css$i,        use'style-loader','css-loader',},{        test\.(png|jpe?g|gif|svg|eot|ttf|woff|woff2)$i,        loader'url-loader',        options{          limit8192,},},,},};

For production builds it’s recommended to extract the CSS from your bundle being able to use parallel loading of CSS/JS resources later on.

When you have pure CSS (without CSS modules), CSS modules and PostCSS in your project you can use this setup:

webpack.config.js

module.exports={  module{    rules{        test\.((c|sa|sc)ss)$i,        use'style-loader',{            loader'css-loader',            options{              importLoaders1,              modules{ autotrue},},},{            loader'postcss-loader',            options{plugins()=>postcssPresetEnv({ stage})},},{            loader'sass-loader',},,},{        test\.(png|jpe?g|gif|svg|eot|ttf|woff|woff2)$i,        loader'url-loader',        options{          limit8192,},},,},};

index.css

.class{backgroundurl(/assets/unresolved/img.png);}

webpack.config.js

module.exports={  module{    rules{        test\.css$i,        use'style-loader','css-loader',},,},  resolve{    alias{'/assets/unresolved/img.png'path.resolve(__dirname,'assets/real-path-to-img/img.png'),},},};

CodingJack’s jQuery Percentage Preloader

September 18, 2013 | Animation, CSS2 / CSS3.0, Plugins, Premium

In the days of Flash we had lots of beautiful percentage-based preloaders. But when websites starting switching over to HTML/CSS/JavaScript, they’ve become almost extinct. Percentage Preloader isn’t ground-breaking technology. Instead, it’s a a clever script that when used correctly, is a fresh alternative to the typical infinite-based preloaders we’re so used to seeing these days. Percentage Preloader is what developers typically call a “bulk loader”. If you only have a one or two assets you need to preload, Percentage Preloader is not for you. But when used with a large number of assets (5+), Percentage Preloader works great at creating the illusion of progress.

Features:

  • Dark and Light Color Schemes
  • 8 Pre-Built Preloaders
  • Designed with CSS making them easy to edit and retina-ready.
  • Preload all the images and iframes on your web page by adding a simple data-attribute to your images.
