W3C CSS Validator errors, should we worry?

[logfiles]

I just bumped onto a validator badge at the bottom left of the forum page today and on clicking on it, it brings some three errors

I don't know much about building websites and I don't have any idea about those validators hence the question. Should we/admin be concerned or it's not that important?

Since its only css related issue, i guess its fine. By the look of it, it only affects the screen resolution looks by some point, the solution is using media queries min-width or max-width instead which is already in used.

While the other one is something like due to JS or backend intervention for checking the hide email checkbox which is not big deal.

I guess if this is just related into CSS is we dont need to worry it's just related with the visuals of the forum but not as the functional of each button and navigation of the links.

Seems just the old style of css which is the

.check

we are commonly use now the

:check

in css. If its related into security of the account and revealing of the information are the most need to care.

Browsers have always been much more forgiving than W3C, so it doesn't matter much.
I think of it as some sort of nerd flex to be W3C complient.
