Is there a reason to use single quotes (') vs. double quotes (") when using the attribute selector?

He does both in the video.

For example, is there any difference between:

input[type='submit']:active { background-color: red; }

AND

input[type="submit"]:active { background-color: red; }

?

Both styles of quotes work the same, but they need to be used in matched pairs.

I used to use single quotes, then later read double quotes were the norm. I view Treehouse as the gold standard of development - the instructor used single quotes ...

Is single quotes preferred?

The only "best practice" is to be consistent with whichever you choose, there's no preference for one style over the other.

Thanks Steven! It'd be easier if one was preferred, lol.

Well, Google's style guide recommends apostrophes (single quotes) for CSS.
