 * I want to have a box in the corner to increase the text size in my site. I found
   the [WP – Writing change [ fontsize and font ] plugin](http://bueltge.de/wp-schift-veraendern-fontsize-und-font-plugin/140)
   and am having trouble understanding how to install it. (I got the unzip and upload
   into plugin folder part). Can anyone help? Thanks!

 * From the site, put one of these in your theme where you want the link:
 * Beispiel-FontSize:
 * >  `<a href="fname('serif','content');">fontstyle serif auf das ID content</a
   > >`
   >  `<a href="fname('Verdana','page');">fontstyle Verdana auf das ID page</
   > a>`
 * This one seems to have two parameters: Font face, and div ID. (My German is a
   little shaky [nil], so if anyone cares to correct this…)
 * Beispiel-FontStyle:
 * >  `<a href="fsize('1.2','em','content');">fontsize 1.2em auf das ID content</
   > a>`
   >  `<a href="fsize('10','%','page');">fontsize 10% auf das ID page</a>`
 * This one appears to have three parameters: Value, units, and div ID.

 * I put them into my theme and all I got were links that said
 * fontstyle serif auf das ID content fontstyle Verdana auf das ID page fontsize
   1.2em auf das ID content fontsize 10% auf das ID page
 * that went nowhere.

 * Well, if you’ve got javascript enabled it shouldn’t go anywhere, but should just
   change your font face/size. You can change the German text within the link to
   whatever you want them to say.

 * That wasn’t it. I have javascript enabled and it didn’t fix the problem. I still
   got an error message.
 * > Not Found
   >  The requested URL /fname(‘serif’,’content’); was not found on this
   > server.
 * Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument
   to handle the request.

 * I’d try contacting the plugin author, then. It might be a problem with their 
   code. That, or see if there’s another plugin that does the same thing (hopefully
   in English!)

 * I think I understand what this is supposed to do. For the fname function, you
   pass it a font name like Palatino and the id that you wish it to be applied to,
   like Content. The fsize function takes a numeric size that corresponds to the
   second parameter units and then the third parameter is the id you wish it applied
   to.

 * Most browsers already implement this. In Firefox, it’s under View->Text Size.
   
   Nevertheless, this ought to work:
 *     ```
       <a href="javascript:void(0);" onclick="
       var fs = document.body.style.fontSize ;
       document.body.style.fontSize = (
       isNaN(parseFloat(fs))
       ? '18pt'
       : (parseFloat(fs) + 2) + fs.substring(parseFloat(fs).toString().length)
       );
       ">Increase Font Size</a>
   
       <a href="javascript:void(0);" onclick="
       var fs = document.body.style.fontSize;
       document.body.style.fontSize = (
       isNaN(parseFloat(fs))
       ? '18pt'
       : (parseFloat(fs) - 2) + fs.substring(parseFloat(fs).toString().length)
       );
       ">Decrease Font Size</a> 
   
       <a href="javascript:void(0);" onclick="
       document.body.style.fontSize = '18pt';
       ">Default Font Size</a>
       ```
   
 * Change “18pt” in all links to font sizes better suited to your site as a default.
   Tested only in Firefox, and that with only a very simple DOM. You may want to
   add image instead of a text link.

 * Alternatively, you could google “PHP stylesheet switcher”, and you’ll come up
   with a ton of stuff. That’s really all you need.

 * I tried using aquazero’s recommendation, which worked but increased all of the
   font sizes including the title on the title page. Can I just increase the body
   and link? Also, what would work for adding a picture?
 * I used
 *     ```
       <img src="http://www.spinalalignment.com/wp-content/uploads/Decrease%20Font%20Size.gif" align="right" onclick=" var fs = document.body.style.fontSize; document.body.style.fontSize = ( isNaN(parseFloat(fs)) ? '18pt' : (parseFloat(fs) - 2) + fs.substring(parseFloat(fs).toString().length) );" title="Increase Font size" /> <img src="http://www.spinalalignment.com/wp-content/uploads/Increase%20Font%20Size.gif" align="right" onclick=" var fs = document.body.style.fontSize; document.body.style.fontSize = ( isNaN(parseFloat(fs)) ? '18pt' : (parseFloat(fs) - 2) + fs.substring(parseFloat(fs).toString().length) );" title="Decrease Font size" />
       ```
   
 *  but it did some strange things (both images at first increased font size then
   would only decrease the font size.

 * Well, search google for the Batavia theme. It comes with a font sizer (a js file)
   and the code in the theme (not sure now which file it is, just have to look through
   it to find the relevant code) to implement it. It’s not a “real” plugin, it’s
   just an external js file and the head link to call it, plus the code in the theme
   to implement the upsize/downsize.

 * makes the link description shorter and more presentable in example….
 *     ```
       <a href="javascript:void(0);" onclick="
       document.body.style.fontSize = '18pt';
       "><img src=" ./yourimage.jpg" /></a>
       ```
