// This script makes it possible to choose a Style Sheet by the user.
// This can be used to change the style/layout of your website by the user and is automatically applied to your whole website (all pages where this script is on).
// This can also be used (and this is for what it is originally made for) to change the font size of all your text on the website
// With this script it is very easy for the user to change all the font size of a whole website; especially good for 50-plus year old people.
