## Description
|
|||
|
|
<section id="description"> Sass允许<code>nesting</code> CSS规则，这是组织样式表的有用方法。通常，每个元素都定位在不同的行上以对其进行样式设置，如下所示： <blockquote> nav { <br>背景颜色：红色; <br> } <br><br> nav ul { <br> list-style：none; <br> } <br><br> nav ul li { <br> display：inline-block; <br> } </blockquote>对于大型项目，CSS文件将包含许多行和规则。这是<code>nesting</code>可以通过在相应的父元素中放置子样式规则来帮助组织代码的地方： <blockquote> nav { <br>背景颜色：红色; <br><br> ul { <br> list-style：none; <br><br> li { <br> display：inline-block; <br> } <br> } <br> } <br></blockquote></section>
