Sometimes you just want to get rid of stuff in a theme but you don’t have the skill or capability to edit it’s source code. Maybe because you don’t have access to it, or because you don’t want to risk your modifications being destroyed in future updates.
The Vanish plugin lets you specify CSS-selectors of elements to be hidden in your theme. A style block is inserted in <code><head></code> which hides all matching elements from view. They are still present in the source code, they will just be invisible.

A plugin for making elements "vanish" from your Wordpress site.

Intended users: Template Designers, Developer
If you wish to add any custom HTML to the bottom of each page’s head, then this plugin is for you. For example, you can add some custom CSS, a link to an external javascript file or something else.
The problem with editing the template directly is if you ever update the template, your changes will be lost. This plugin works around this issue.
