What is the difference between using link and @import in css?

• link is an XHML tag, in addition to loading css files, you can also load other transactions of RSS, while @import can only load css
• Link has no browser compatibility issues, import is supported in lower version browsers
• When the link tag references the css file, it is loaded at the same time as the page is loaded; @import can only be loaded after the page is fully loaded
