CSSSelector in short

CSSSelector was inroduced as part of the HTML5/CSS2 initiativ. In many ways you may say that it is for webprogrammers what XPATH is for XML-programmers. A CSSselector make it possible to identify element(s) on a webpage combing the structure (HTML) and the stylesheet (CSS).

WXT use CSSSelector when importing HTML fragments from HTML-pages. The syntax is rather involved and you may find support at jsoup [23] , at w3schools [24] and the reference document at w3org [25] .
