Pseudo-classes

:target

The :target pseudo class allows us to select an element on the page that has been targeted in the URL.
The element can be any element with an id: <div id="preview"> or name anchor like: or <a name="preview" ></a> and should be unique on the page.
The target of a url is the part after the '#' symbol eg. 'preview' in this url: http://csscreator.com/content/target#preview
Loading a page with an anchor takes you to that part of the page.
