With the definition of HTML5 picking up speed, there are a number of HTML 4.01 elements which we should now consider avoiding when we build our web pages, simply because they’re being dropped from the HTML5 spec.

Many of these elements were already deprecated in HTML4, however there are a few elements missing in HTML5 that were not already deprecated, such as acronym and frame.

The elements experiencing earnest disapproval in HTML5 are:

  • basefont
  • big
  • center
  • font
  • s
  • strike
  • tt
  • u
  • frame
  • frameset
  • noframes
  • acronym
  • applet
  • isindex
  • dir

Incidentally, for those who remember menu, you’ll be pleased to learn that it’s back in favour and is all set to make a return in HML5 – hoorahh!

More info on HTML5 can be unearthed in the HTML5 spec.

Enjoy!
