   <p>{{s84 You need to download the web page so you will necessarily download the advertisements. All you can do here is to hide the advertisement so you don't need to see it. That's what element hiding is meant for.}}</p>
 
-  <p>{{s85 The first advertisement above is contained inside an element with class attribute "textad". The following rule will hide exactly any such element: <code><fix>##.textad</fix></code>. 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, <code><fix>###sponsorad</fix></code> will hide the second advertisement. And you can hide elements by element name only, e.g. <code><fix>##textad</fix></code> for the third advertisement.}}</p>

Nit: "only" doesn't make sense here any more.

Done.

   <p>{{s86 The <a href="elemhidehelper">Element Hiding Helper extension</a> helps selecting the correct element and writing the corresponding rule without having to view the source code of the page. Basic HTML knowledge is useful nevertheless.}}</p>
 
   <p>{{s87 <em>Note</em>: Element hiding works very differently from normal filters. This has the implication that no wildcards are supported in element hiding rules.}}</p>
 
   <h3 id="elemhide_domains">{{s88 Limiting rules to certain domains}}</h3>
 
   <p>{{s89 Usually you want to hide a specific ad on one specific site, you don't want your rule to be applied on other sites. For example the rule <code><fix>##.sponsor</fix></code> might hide valid code on some sites. But if you write it as <code><fix>example.com##.sponsor</fix></code> it will be applied on <code><fix>http://example.com/</fix></code> and <code><fix>http://something.example.com/</fix></code> but not on <code><fix>http://example.org/</fix></code>. You can also specify multiple domains — simply separate them with commas: <code><fix>domain1.example,domain2.example,domain3.example##.sponsor</fix></code>.}}</p>
 
   <p>{{s90 If a domain name is preceded with "~", the rule will <strong>not</strong> be applied on pages from this domain (requires Adblock Plus 1.1 or higher). For example, <code><fix>~example.com##.sponsor</fix></code> will be be applied on pages from any domain but "example.com" and <code><fix>example.com,~foo.example.com##.sponsor</fix></code> makes the rule apply on "example.com" domain with the exception of "foo.example.com" subdomain.}}</p>
