I am reading Mobile HTML5 written by Estelle Weyle. It is an awesome recap and new knowledge about html, css and javascript. I want to highlight one of tips I got: Use the weakest CSS selectors (can be found on page 204). We all know, that inline CSS and !important are evil. They have a higher level of specifity and override the standard cascade of the CSS rules. If you use !important, then it will be hard to override CSS rules when you really need it. After these two classic “evils” the evil number three is overqualifying of CSS selectors. You should really never add more classes or ids or elements than needed. Consider this:

There are situations when you want to select only dom elements which only have a specific content. jQuery provides a beautiful selector :contains:

$("a:contains(Pages)")
```But what if it isn't enough to just get all the elements which contain some word? Let's check what we get if we traverse all anchors on http://sv.wikipedia.org containing "wiki":

$(“a:contains(wiki)”).each(function(i) { console.log($(this).text()); });

[![](https://sharepointkunskap.files.wordpress.com/2012/02/jquery-contains-wiki.png "jquery-contains-wiki")](https://sharepointkunskap.files.wordpress.com/2012/02/jquery-contains-wiki.png) There is another, a generic way, to filter out elements, and it is called "filter". So a little regex check will do the trick.

$(“a”).filter(function() { return /look_for/i.test($(this).text()); }

Want to hide my site link without disabling social features. Well, the simplest way to do it is to use css:

#mp1\_0\_0\_Anchor { display: none; }
```If you want to hide my profile instead, just hide #mp1\_0\_1\_Anchor:

#mp1_0_1_Anchor { display: none; }

.ms-MenuUIUL li[text=‘My Site’] { display: none;}

##### Disable the my profile feature An even better solution is maybe to disable the ability to change the profiles. [Just remove the permission to "user personalization..." for All authenticated users in User Profile Service](http://blog.libinuko.com/2010/10/10/sharepoint-2010-howto-disable-my-site-and-my-profile-link/).
