Rocket Validator automatically checks your pages on the W3C Validator.
HTML issues tagged as missing value.
An attribute has been found in an element, where the intended value is missing. A common cause is including the equal sign, but not passing anything after it.
<!-- This is missing the value for the style attribute, so it's invalid --> <p style=></p> <!-- This is explicitly passing a blank string as the value, so it's valid --> <p style=""></p>
