HTML Checking for Large Sites
Rocket Validator automatically checks your pages on the W3C Validator.
HTML issues tagged as matching.
Quote characters used for attributes can use either single quotes (') or double quotes ("), and they must be properly matched, for example:
<p class="news">...</p>
A common cause for this issue is forgetting to use the equal sign (=), so the HTML parser wrongly believes the quote forms part of the attribute name, for example:
<p class "news">this is wrong</p>25,000 HTML checks per month. Is that enough for your site?
