The difference between href and src:

Href (Hypertext Reference): hypertext references, commonly used tags such as link, a, etc., are used to link referenced external resources. Define a link or relationship between the current element or document and the required anchor or resource defined by the current attribute, such as:

Src (source): the introduction of resources, the introduction of src content is an essential part of the page. The introduced content is embedded in the current resource into the location defined by the current document element, such as img, script, iframe, and so on. Such as:

The loading and processing of the page is paused before the browser downloads, compiles, and executes the file (when the browser parses the element, the browser's rendering is paused), which is why it is recommended to load the js file at the bottom. The img tab is similar, and the browser pauses loading until the image is extracted and loaded.

The difference between link and @ import:

Both are ways of referencing CSS externally, but the differences are as follows:

Distinguishing that 1:link is a XHTML tag, you can define other transactions such as RSS in addition to loading CSS; @ import belongs to the category of CSS and can only load CSS.

The difference is that when 2:link references CSS, it loads at the same time as the page loads; @ import requires the page page to be loaded after it is fully loaded.

The difference between 3:link is the XHTML tag and there is no compatibility issue; @ import is proposed in CSS2.1 and is not supported by lower versions of browsers.

Distinguishing 4:link supports using JavaScript to control DOM to change styles; @ import does not.
