Differences between 'url', 'src', and 'href'

Question

Difference between SRC and HREF

When writing html/css, it seems like these all do the exact same thing. Obviously this is not the case, and if you 'href' when your supposed to 'src' your gonna have a bad time. But my question is, is there an easy way to remember which ones do which, and when they are used?

Solution 1

1. In CSS, it's always url.
2. In HTML:
   1. It's href (short for Hypertext REFerence) for all kinds of links, including tags a and link.
   2. When it's not a link, you are setting the source, so it's src.

Solution 2

src -- I want to load up this resource for myself.

href -- I want to refer to this resource for someone else.

url -- A script wants to use this url as a variable.

Not necessarily a variable. A URL is just that: a URL.
