When to use it
One of the three fractions in HTML 4 (½, ¼, ¾). HTML5 names thirds, fifths, sixths and eighths too, and any other fraction can be built with <sup>, <sub> and the fraction slash ⁄. ½ is an alias.
The name dates from HTML 4, so it works in every browser and in old email clients.
Browsers also accept the legacy form ½ without a semicolon, for compatibility with old pages; new HTML should always end the reference with a semicolon.
