Superscripts are Super!

The <sup> script is used to identify text that should appear in a superscript position relative to the surrounding text. Use the element for it's semantic meaning, rather than for it's styling. If all you want to do is make a character appear superscript for stylistic purposes, CSS is the right tool for the job. Let's take a look at how we might do that using this CSS snippet created by Ruthie BenDor with some light modification.

<style> .sup {   font-size: 75%;   line-height: 0;   position: relative;   vertical-align: baseline;   top: -0.5em } </style> <p>Use CSS for superscripts that are stylistic rather than textual, such as the superscripts in this completely fictional brand: Awesome<span class="sup">SQUARED</span>.</p> 

Let's see what our browser does with that bit of HTML.

Use CSS for superscripts that are stylistic rather than textual, such as the superscripts in this completely fictional brand: AwesomeSQUARED.
