The Difference Between url, scr, and href in HTML

• url is not an attribute, src and href are attributes, src is used to replace the current element, and href is used to establish a connection between the current document and the referenced resource, that is, the path referenced by src is the path to be loaded by img and other elements, and the path referenced by href is the place to be jumped to.

• src is the abbreviation of source, which indicates the introduction of a file, the purpose of which is to load the file into the html page. When the browser parses it, it will pause other content and load the src content first, and it must wait until the src content is loaded before executing the subsequent content. (Commonly used: img, script, iframe)

• href is the abbreviation of Hypertext Reference, which indicates a hypertext reference, pointing to the location of the network resource, establishing a link between the current element (anchor) and the current document (link), and its relationship with the page is that of a link. When it is loaded, the page itself will not stop loading other content. It is used to establish a link between the current element and the document. (Commonly used: link, a)
