HTML Checking for Large Sites
Rocket Validator automatically checks your pages on the W3C Validator.
HTML issues tagged as displayText.
The attribute displayText
is not allowed on <span>
elements.
This issue is commonly caused by an old integration of ShareThis via Drupal or other CMS - the old code used invalid attributes like displayText
, st_url
and st_title
which were later changed to HTML5 custom data attributes.
