I just think it's odd that she's using the completely incorrect term in a professional setting where she's trying to convince a future employer that she can do the job.

Bearing in mind that there's a good chance that her prospective future employer probably couldn't describe the task even that well, I'd be willing to give her a pass on that one.

If I was the prospective employer, it would actually serve a great purpose for me, it tells me that she has some amount of experience with the technicalities of the Internet, but not a great depth in this kind of area. She seems to be going for writing jobs ideally, not a dev or server admin position or something, so this would not necessarily be a detractor to her overall pitch. And you can tell she's pitching to non-technical people:

"I can even make that div float so that the text doesn’t get all messy. Don’t know what that means? See, you really should hire me."

I quite liked that passage.

She also refers to "software packages like Microsoft Office and Adobe Suite" where I would in any similar situation at least refer to it as "the Adobe Suite" and most likely I'd be a little more specific than that, going into further detail about which apps in the suite I actually have experience with. But again, I give her a pass because the way she's written things up I suspect works for the audience she's targeting.
