Replace deprecated HTML tags in HTML5
Closed, InvalidPublic

Description

Like it is done for deprecated attributes (function fixDeprecatedAttributes in Sanitizer.php), deprecated HTML tags should be replaced by CSS, too.

These tags are (see URL):

  • big
  • center
  • font
  • strike
  • tt

For big, strike and tt this should be easy. font requires the obsolete attributes to be converted to CSS.
I'm not sure, whether it is actually possible to replace center,

<center><table><tr><td>a</td></tr></table></center>

centers the table (tested in Firefox), but something like

<div style="text-align:center; margin-left:auto; margin-right:auto;"><table><tr><td>a</td></tr></table></div>

doesn't.

The changed tags should be given an extra CSS class in order to be able to address them using CSS.
