Glossary-Definition::Cascading Style Sheets (Glossary-Term::CSS) is a style sheet language used to describe the presentation semantics (the look and formatting) of a document written in a markup language. Its most common <math>\frac{2}{\sqrt{\pi}}</math> application is to style web pages written in HTML and XHTML.

<math>
 \operatorname{erfc}(x) =
 \frac{2}{\sqrt{\pi}} \int_x^{\infty} e^{-t^2}\,dt =
 \frac{e^{-x^2}}{x\sqrt{\pi}}\sum_{n=0}^\infty (-1)^n \frac{(2n)!}{n!(2x)^{2n}}
