Pseudoselectors
Style rules are normally attached to elements in the
document tree structure, such as those we’ve discussed in the chapter so
far. But some elements are not necessarily found in the document markup,
such as which links have been visited or the first line of a paragraph. To
apply style to these instances in a document, CSS provides several
pseudoselectors . Instead of targeting a particular element in the
document, pseudoselectors are interpreted by the browser based on context
and function. Pseudoselectors are indicated by the colon (:) character. Pseudoselectors are divided into
pseudoclasses and pseudoelements.
