The difference between link and @import in css
The difference between link and @import in CSS: the syntax is different, link uses the <link> element in HTML, and @import uses the @import statement in CSS. The import methods are different, link is inserted directly into the HTML document, and @import refers to an external style sheet in the CSS file. Blocking rendering is different, link blocks rendering, and @import does not block. The cascading order is different, link is cascaded in HTML order, and @import is cascaded before the style sheet is introduced. Browser support is different, link is supported by all modern browsers, @import is not supported by older browsers. Maintenance is different, link is easier to maintain, @import may
The difference between link and @import in CSS

link: Supported by all modern browsers.
@import: Not supported by older browsers (such as IE8 and earlier).

link: Easier to maintain because all CSS files are independent.
@import: May cause maintenance issues because stylesheets become interdependent.
