Attribute selectors

Some advertisers don't make it easy for you — their text advertisements have neither an id nor a class attribute. You can use other attributes to hide those, for example ##table[width="80%"] will hide tables with width attribute set to 80%. If you don't want to specify the full value of the attribute, ##div[title*="adv"] will hide all div elements with title attribute containing the string "adv". You can also check the beginning and the end of an attribute, for example ##div[title^="adv"][title$="ert"] will hide div elements with title starting with "adv" and ending with "ert". As you see, you can also use multiple conditions — table[width="80%"][bgcolor="white"] will match tables with width attribute set to 80% and bgcolor attribute set to white.

The first advertisement above is contained inside a div element with class attribute "textad". The following rule will hide exactly this combination: ##div.textad. Here ## marks an element hiding rule while the rest is a selector identifying the elements that need to be hidden. You can hide elements by their id attribute similarly, ##div#sponsorad will hide the second advertisement. You don't need to specify the element name, the rule ##*#sponsorad will work just as well. And you can hide elements by element name only, e.g. ##textad for the third advertisement.
