Page "Skin (computing)" Paragraph 8

Many websites are also skinnable, particularly those which provide some social capabilities.

Again, some sites offer skins that make primarily cosmetic changes, while some — such as H2G2 — allow major changes to the layout of pages.

As with standalone software interfaces, this is facilitated by the underlying technology of the website — the use of XML and XSLT, for instance, facilitates major changes of layout, while CSS can be used to easily produce different visual styles.
