First suggestion: use body instead of html for your formatting. Like:

  <style type='text/css'>
  html{
  font-size: 300%;
  }
  </style>

Even so, you should just delete that at the beginning so the font size will be variable.

 

if($_SESSION['FontSize']=='')
{
  ?>
  <style type='text/css'>
  body {
  font-size: 100%;
  }
  </style>	
  <?php
}

 

The browser doesn't know that the <style> is in an if statement. Any thing that is not in the <?php ?> tags is ignored by PHP, but even if you didn't drop out of PHP.

I would suggest:

if(!isset($_SESSION['FontSize']))
{
  echo '<style type='text/css'>
  body {
  font-size: 100%;
  }
  </style>';
}

 

That will output your style to the browser, so it's interpreted only when FontSize is blank.

I also added an isset so that it checks if the variable is not set, rather than if it is blank.

 

There may be a few other errors, I'm not sure; I'm no expert.

hi,

 

i have tested whit only this:

if(!isset($_SESSION['Size']))
{  
  echo '<style type='text/css'>  
  body {  
  font-size: 300%;  
  }
  </style>';
}

 

like you said, butt my text stays the same??? why???

 

see http://nieuw.pc-hulp-online.nl/index.php

 

thnx

 

Put your url in here at http://validator.w3.org/ . It says you have 8 errors, 1 is no doc type and another says doc type does not allow style here.

 

This link and firefoxes firebug are handy tools.

 

butt it dont said how to fix it!!

It could be a matter of 300% of what?  Without testing I'm not 100% sure on this but you might try defining a default size, then go 300%.  I also see you're using "if (!isset" which I assume is for testing.

<style type='text/css'>  
  body {  
  font-size: 11px;  
  }
  </style>
if(!isset($_SESSION['Size']))
{  
  echo '<style type='text/css'>  
  body {  
  font-size: 300%;  
  }
  </style>';
}

 

EDIT:  You need a doctype declaration.  replace your <html> with this

 

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
