HTML Checking for Large Sites
Rocket Validator integrates the W3C Validator HTML checker into an automated web crawler.
HTML issues tagged as border.
<img> tags no longer accept a border attribute. This can be defined using CSS instead, for example:
<img src="..." alt="..." style="border:0;" />When was the last time you validated your whole site?
Keep your sites healthy checking for A11Y/HTML issues on an automated schedule.
