If the validator gives Warning (not Error, namely Warning) — how bad is it? Is a valid layout or not?


Warning: count(): Parameter must be an array or an object that implements Countable in /home/styllloz/public_html/qa-theme/donut-theme/qa-donut-layer.php on line 274

Actually, a subject. If my layout issues and warning', then it is invalid layout? And it loses its advantage in cross-browser and indexed by search engines?

Leave it. The validator though, and is to the benefit of standardization, but in fact it is necessary to operate vospriimchivosti browsers to layout and not to look at this validator at all. Better to try and use Lint'ers )) that the onm that will help you to do the right thing
