A font size changer, written in php. rather than loading different style sheets this changes the body font size. As such it may not work with all themes.
Download the plugin, upload to your Wordpress plugins directory and activate.
By adding the following to you theme, inside the body:\
efontsize('85');
\
you can set the default body text size, a default of 100.1 will used if the value is omitted.
As seen on
http://elfden.co.uk/ I used this style to position the links at the top right hand side:
ul.efontsize{ position:absolute; top:0; right:0; z-index:999; } ul.efontsize li{ display:inline; margin-right:5px; }
