HTML-CSS: Tips of the Day

CSS strikethrough different color from text?

Yes, by adding an extra wrapping element. Assign the desired line-through color to an outer element, then the desired text color to the inner element. For example:

<span style='color:red;text-decoration:line-through'>
  <span style='color:black'>black with red strikethrough</span>
</span>

...or...

<strike style='color:red'>
  <span style='color:black'>black with red strikethrough<span>
</strike>

(Note, however, that <strike> is considered deprecated in HTML4 and obsolete in HTML5. The recommended approach is to use <del> if a true meaning of deletion is intended, or otherwise to use an <s> element or style with text-decoration CSS as in the first example here.)
