Описание
CSS свойство background обеспечивает краткий метод установки значений сразу нескольких свойств для работы с фоном в одном объявлении.
Допускается указывать значения следующих свойств: background-clip, background-color, background-image, background-origin, background-position, background-repeat, background-size и background-attachment.
Значения свойства разделяются пробелом и могут следовать в любом порядке, браузер сам определит, какое из них соответствует нужному свойству. Все значения указывать не обязательно, любое из них можно опустить, в этом случае вместо пропущенного значения будет использовано значение, которое установлено для свойства по умолчанию, например, если не указано как должно повторяться фоновое изображение, то будет использовано значение по умолчанию свойства background-repeat.
Если в свойстве задаётся размер изображения (background-size), то он должен указываться после указания начальной позиции изображения, через символ / (слэш):
background: background-position/background-size;
Размер изображения указывается только в паре с указанием начальной позиции. Но указание начальной позиции не обязательно указывать в паре с размером изображения.
Совет: когда вы одновременно задаете элементу задний фон и рамку, помните: если стиль рамки — точечная или пунктирная линия, то фоновый цвет или фоновое изображение будет проступать в промежутках между точками или штрихами линий рамки. Другими словами, по умолчанию браузеры размещают линию рамки поверх фона.
Значение по умолчанию: | смотрите отдельно каждое свойство, входящее в состав краткого метода |
---|---|
Применяется: | ко всем элементам, а также к псевдо-элементам ::first-letter и ::first-line |
Анимируется: | да, смотрите каждое свойство, входящее в состав краткого метода, отдельно |
Наследуется: | нет |
Версия: | CSS1, CSS3 |
Синтаксис JavaScript: | object.style.background=»red url(smiley.gif) top left no-repeat» |
Property Values
Value | Description |

none | Default value. No shadow is displayed |
h-shadow | Required. The position of the horizontal shadow. Negative values are allowed |
v-shadow | Required. The position of the vertical shadow. Negative values are allowed |
blur | Optional. The blur distance |
spread | Optional. The size of shadow |
color | Optional. The color of the shadow. The default value is black. Look at CSS Color Values for a complete list of possible color values.Note: In Safari (on PC) the color parameter is required. If you do not specify the color, the shadow is not displayed at all. |
inset | Optional. Changes the shadow from an outer shadow (outset) to an inner shadow |
initial | Sets this property to its default value. Read about initial |
