'''[[Subscript and superscript|Superscripts and subscripts]]''' appears smaller than the normal line of type and is set slightly below or above it and have many uses. This part of the [[Wikipedia:Manual of Style|Manual of Style]] aims to achieve consistency in the use and formatting of superscripts and subscripts in Wikipedia articles.
Subscripts and superscripts should be wrapped in <code><sub></code> and <code><sup></code> tags, respectively, with no other formatting info. Do not use the [[Unicode subscripts and superscripts]] {{!xt|<span class="bad_example" style="color: #B20000;">²}}</span> and {{!xt|<span class="bad_example" style="color: #B20000;">³}}</span>, or [[List of XML and HTML character entity references|XML/HTML character entity references]] (<code>&sup2;</code>). Rather write <code><nowiki><sup>2</sup></nowiki></code> and <code><nowiki><sup>3</sup></nowiki></code> to produce the superscripts {{xt|<span class="example" style="color: #006F00;"><sup>2</sup>}}</span> and {{xt|<span class="example" style="color: #006F00;"><sup>3</sup>}}</span>. The superscripted 2 and 3 are easier to read, especially on small displays, and ensure that exponents are properly aligned. Compare:
: {{!xt|<span class="bad_example" style="color: #B20000;">wⁱx²y³z⁽ⁿ⁺⁶⁾}}</span> to
