Comment (by afercia):

 @dd32 the `title` attribute works like a description and gets announced
 ''in addition'' to the visible text. So:
 {{{
 <abbr title="pixels">px</abbr> = pee ex (short pause here) pixels
 }}}

 Also, there's no guarantee the title attribute will be announced, it
 depends on the verbosity settings user can tweak in their screen readers.

 The `aria-label` attribute ''replaces'' the content instead:

 {{{
 <span aria-label="pixels">px</span> = pixels
 }}}
 By the way, it tends to work best on interactive elements. Thinking also
 at the resulting translatable string, it would be simpler to use just
 plain text.
