I really could just explain this really easily, huh? Alright, so, the "a" tag, is

"a" tags are basically Links, and Links can either be embeds, or straight up This.

Just to show what an embed is, really, and also I just wanna try this out:

Still kind of counts as a link, but is not an "a" tag. ... Still cool nonetheless, though.

You can also put them in images, so I will do that while also showing you, and linking you, to a page that shows more about the "a" tag.

Well, that wraps it all up, I hope you learned something. Probably didn't, but you can't blame me for trying.
