篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了160908前端开发框架Semantic UI相关的知识，希望对你有一定的参考价值。

简介

网页开发中，CSS控制网页样式。作为测试开发工程师，我个人不太擅长手写CSS、样式微调、兼容浏览器等工作，所以我选择使用成熟的前端框架，可以快速开发出样式美观的网站，也解决了大部分浏览器兼容问题。前端框架百花齐放，我们公司的产品使用了Bootstrap，我个人使用的是Semantic UI。

安装Semantic UI

首先需要安装node、全局安装gulp（我使用的是Mac环境）：

  • brew install node
  • sudo npm install -g gulp

然后进入项目的静态文件目录，比如我的是/learnflask/static，执行npm install semantic-ui --save，进行一些Semantic UI的设置后，安装完成（我设置的Semantic UI目录是/learnflask/static/semantic)后cd到Semantic UI目录，执行gulp build命令。

使用Semantic UI

使用Semantic UI，只需要在html文件头部引入如下3个文件即可（使用了又拍云的jQuery的CDN）：

<script src="http://upcdn.b0.upaiyun.com/libs/jquery/jquery-2.0.2.min.js"></script>
<link rel="stylesheet" type="text/css" href="semantic/dist/semantic.min.css">
<script src="semantic/dist/semantic.min.js"></script

按钮

学习前端框架无非是学习其各个组件，我们先从按钮开始。

标准按钮

<button type="button" class="ui button">Click</button>

样式如下：
