font-family: Monaco, Menlo, Consolas, "Courier New", monospace; border-radius: 3px; border: none; background-color: rgb(247, 247, 249);">LESS</code> ， <code style="padding: 2px 4px; font-family: Monaco, Menlo, Consolas, "Courier New", monospace; border-radius: 3px; border: none; background-color: rgb(247, 247, 249);">SASS</code> 都在这方面做了一些贡献。<code style="padding: 2px 4px; font-family: Monaco, Menlo, Consolas, "Courier New", monospace; border-radius: 3px; border: none; background-color: rgb(247, 247, 249);">Stylus</code> 是一个CSS的预处理框架，2010年产生，来自Node.js社区，主要用来给Node项目进行CSS预处理支持，所以 <code style="padding: 2px 4px; font-family: Monaco, Menlo, Consolas, "Courier New", monospace; border-radius: 3px; border: none; background-color: rgb(247, 247, 249);">Stylus</code> 是一种新型语言，可以创建健壮的、动态的、富有表现力的CSS。比较年轻，其本质上做的事情与 <code style="padding: 2px 4px; font-family: Monaco, Menlo, Consolas, "Courier New", monospace; border-radius: 3px; border: none; background-color: rgb(247, 247, 249);">SASS</code> / <code style="padding: 2px 4px; font-family: Monaco, Menlo, Consolas, "Courier New", monospace; border-radius: 3px; border: none; background-color: rgb(247, 247, 249);">LESS</code> 等类似，应该是有很多借鉴，所以近似脚本的方式去写CSS代码。<code style="padding: 2px 4px; font-family: Monaco, Menlo, Consolas, "Courier New", monospace; border-radius: 3px; border: none; background-color: rgb(247, 247, 249);">Stylus</code> 默认使用 <code style="padding: 2px 4px; font-family: Monaco, Menlo, Consolas, "Courier New", monospace; border-radius: 3px; border: none; background-color: rgb(247, 247, 249);">.styl</code> 的作为文件扩展名，支持多样性的CSS语法。<code style="padding: 2px 4px; font-family: Monaco, Menlo, Consolas, "Courier New", monospace; border-radius: 3px; border: none; background-color: rgb(247, 247, 249);">Stylus</code> 功能上更为强壮，和js联系更加紧密。所以我选择 <code style="padding: 2px 4px; font-family: Monaco, Menlo, Consolas, "Courier New", monospace; border-radius: 3px; border: none; background-color: rgb(247, 247, 249);">Stylus</code> ， <code style="padding: 2px 4px; font-family: Monaco, Menlo, Consolas, "Courier New", monospace; border-radius: 3px; border: none; background-color: rgb(247, 247, 249);">SASS</code> 玩儿过一段时间，主要是这玩意依赖ruby运行，所以我放弃使用了。<h2 style="margin-bottom: 0.5em;

border-radius: 3px; border: none; background-color: rgb(247, 247, 249);">nodejs</code> 这个怎么安装搜去哦。<pre class="ruby" style="padding: 0.3em; font-family: Monaco, Menlo, Consolas, "Courier New", monospace;
