What is pseudo?
Language describing the structure of documents - such as XHTML or HTML - do not provide mechanisms for access to certain specific elements present on every page. For example, you can not directly refer to the first letter or first line of the paragraph. Meanwhile, they often need special wystylizowania. The placement of the first letter in each paragraph tag <span> ... </ span> is a sub-optimal and time consuming.
With the help of CSS pseudo-come, that allow to refer to such special parts of the document structure without the need for any additional tags to the source code. Pseudo also allow you to automatically generate a certain content in certain areas of the document, which normally is not in your source code. That refers to a special text preceding or following example, after a paragraph.
