I have come across a piece of free script that can be added in to change the font size - I include it below for information. However, it only changes the css on that particular page (I created the page in staticpages and was logged in as admin) not to the site as a whole - does anyone know how to make it remain until it is changed again by the user (logged in or not)?
Text Formatted Code
<!-- THREE STEPS TO INSTALL CHANGE STYLE:
1. Copy the coding into an external file named "changeStyle.js"
2. Place a link to the external file into the HEAD of your HTML document
3. Add the last code into the BODY of your HTML document -->
<!-- STEP ONE: Paste this code into an external file named "changeStyle.js" -->
<HEAD>
<script type="text/javascript">
