HTML编辑器(1)
前言
现在网上有很多这样的HTML编辑器，这种编辑器无疑给人带来了很多方便，所以自己也想尝试制作一款这样的HTML编辑器，既然要制作，那就肯定是先把UI搭起来，再慢慢完善功能
设计思路
我的思路就是将div标签设置一个属性（contenteditable="true"），使div成为可编辑的div
并且我发现可编辑div有个特征：在内部换行会将上一个标签复制下来，所以为了防止这种问题，我决定在内部加入<p><br></p>这样，每次换行就会自动复制<p><br></p>标签
把这些东西弄好后，我就开始写UI，俗话说:交互也是一门技术
UI用的Icon使用了图标字体
后面使用html写好了交互的菜单以及用css做了交互效果

鼠标移到Icon
鼠标移到有下拉框的Icon
