我们可以在另一个css声明中导入额外的css文件。@import规则用于此目的,它在文档中链接样式表。通常在一个样式表依赖于另一个样式表时使用。它在93f0f5c25f18dab9d176bd4f6de5d30e标签内的@charset声明之后的文档顶部指定。
syntax@import规则的语法如下:
@import /*url or list-of-media-queries*/
the media queries can be compound statements which may specify the behavior of the document in different media.
examplethe following examples implement the @import rule −
html document −
<!doctype html><html><head><style type="text/css">@import url(style.css);body { background-color: honeydew;}</style></head><body><p>this is demo paragraph one. </p><p class="two">this is demo paragraph two.</p><p>this is demo paragraph three</p></body></html>
css文档:style.css
p { color: navy; font-style: italic; }.two { color: darkgreen; font-size: 24px; }
输出这将产生以下输出 −
示例html文档 −
<!doctype html><html><head><link rel="stylesheet" type="text/css" href="style.css"></head><body><div></div></body></html>
