Introduce the test.css file into test.html
//写在head标签中引入css文件,href属性中的为绝对路径,当前在同一级目录下 <link href="test.css" type="text/css" rel="stylesheet" /> //写在body标签中 <div>链接式</div>
Imported
@import(url(demo.css))
Basically not used, because the page will load html first, and then load css, which will cause a delay in page style.
Create a demo.css file and write a css style
//写在demo.css文件中 h2{ color:green; }
Use @import method to import the demo.css file
//试验了一下,需要单独写在一个style中, <style> @import url(demo.css) </style> //写在body标签中 <h2>导入式</h2>
