WebCheez Posted April 28, 2012 Share Posted April 28, 2012 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.

floridaflatlander Posted April 28, 2012 Share Posted April 28, 2012 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.

Drummin Posted April 28, 2012 Share Posted April 28, 2012 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"> Quote Link to comment Share on other sites More sharing options...
