/**
* Step 1: Add the following code to the section of your web page:
*
*
* Step 2: Now set up the two links that will increase and decrease your text size. The following will do nicely:
* + Larger Font |
* + Smaller Font
*
* And that's it!
*
* Customization
* There are two areas within the script you can make changes.
*
* First, within textsizer.js, you can add additional HTML tags the script should affect. Lets say your webpage's
* text are all controlled using explicit tags. You can add "font" as a tag the script should affect.
*
* Second, inside the code of Step 2, you may substitute "body" with another tag name or even ID name, to
* localize the text size manipulation to only the specified containers.
