在Visual Studio Code中使用CSSComb格式化CSS文件

不管是在JS文件还是在HTML文件中,右键点击,都有“格式化文件”的菜单,帮助我们排版。可是在CSS文件中,却没有这样的选项,这时候我们就要通过插件帮我们完成这项工作了。先看下格式化后的效果图:

一、安装插件

​ 在Visual Studio Code的扩展工具栏中,在搜索栏中输入“csscomb”,就可以找到该插件并安装了。

二、配置

​ 在Visual Studio Code的“文件”->“首选项”->“设置”中,添加一行如下:
​ 然后,在项目的根目录下,添加一个文件,名为“.csscomb.json”,修改内容如下:

        ".git/**",

​ 这时候我们就可以对CSS文件格式化了。
​ 打开一个CSS格式文件,按“F1”,选择“CSSComb: Format styles”,格式化成功!
