Is CSS validation no longer relevant?

Question

I've just built my first webpage for years, using HTML5, Bootstrap and jQuery.

When I ran the page through the W3C CSS validator the result returned contained nearly 800 errors (from Bootstrap mostly).

Is CSS validation no longer relevant or is there a more up-to-date css validator that I can use?

Thanks, N

Answer 1

It depends what Profile you select.

From the amount of errors you received, you probably selected the default CSS level 2.1

Try changing this to CSS level 3
