Add to your website a functionality of text resize by click.
jQuery Text Resizer
This plug-in allows you to create controls for changing the font size of one or more elements on a page. It gives your users a fine degree of control over font sizes. It’s flexible in that it lets you specify exactly how to resize text, how it should be styled (via CSS or CSS3), where in your page it should be resized, and how the font size controls are to be structured.
Typography is so important; jQuery Text Resizer can aid you in creating the controls for sizing content on demand.
The plugin works in tandem with the jQuery Cookie plugin, so that it’s able to remember the user’s settings on their next visit.
The demo uses simple 4 links, of course it can be integrated with nice icons (e.g. “+” and “-“), for better look and feel.
