I'm using HTML purifier module in Drupal 7. I know that, marquee isn't a valid HTML tag and HTML purifier doesn't support it, but I had to use the tag because of a jQuery scroller that uses a <marquee> tag.
I cannot use CSS3 animations to scroll a piece of text to respect old web browsers.
So, how can I allow a marquee tag on Drupal 7 using HTML purifier?
