Enable users of your site to increase or decrease the font size, and switch
between different views. The switcher controls use multiple CSS stylesheets
and render the links to the different style sheets when necessary to modify the
styling of the site. This satisfies accessibility requirements to allow users
to see a larger font, or use different colour schemes, or even no styling at all.
CSS Switcher
By creating multiple CSS stylesheets that manipulate the HTML in different ways
you can switch between them easily by using the CSS Switcher.
Font Switcher
A simple way of allowing users to increase and decrease the font size in your site
is to create three or more style sheets containing a font-size for the <body> tag.
The Font Switcher will change the stylesheet dynamically, increasing or decreasing
the displayed font size.
