2020-06-30 by Jaime Iniesta

The HTML validation server on Rocket Validator has been upgraded to version 20.6.30 of Validator.nu released by the W3C, which adds some fixes and improvements related with checking CSS, SVG, and ARIA:

CSS: Improvements in calc(), min()/max() checking.
Allow height and width attributes for SVG symbol element.
Allow capture attribute for the input[type=file] element.
Allow disabled attribute for the link[rel=stylesheet] element.
Treat custom elements as labelable elements for label[for] handling.
ARIA: Fix bug that disallowed implicit combobox/listbox for select.
ARIA: Improve error message for alt-less img with ARIA attributes.
ARIA: Allow section[role=doc-glossary].

Time to re-check your sites!

As usual, it's recommended to re-check your sites after the validation servers have been upgraded, to get the most up-to-date results. Remember that you can schedule your reports to run periodically, so you don't have to do that manually every time.
