Using both @import and link tag you can include style sheet in a webpage. But there is a difference.
For performance “link” has a much better advantage.
Example of @import and link:
<link href="style.css" type="text/css" /> <style type="text/css"> @import url("style.css"); </style>
As @import allows you to import one style sheet into another but older browsers didn’t recognize @import so for old browser it is better to use <link>.
