HTML Checking for Large Sites

Rocket Validator automatically checks your pages on the W3C Validator.

HTML issues tagged as unquoted.

Attribute values for HTML elements must be enclosed within quotes. Check for attributes whose values are missing quotes.

Example:

<!-- These are invalid -->
<div class=important></div>
<div class=important"></div>

<!-- This is valid -->
<div class="important"></div>
