Question

Checking screen resolution then changing the style to fit

Asked by: baumli

I want to be able to check the screen resolution, then create a font style depending on which resolution is being used.  Can't seem to get it to work.


<style type="text/css"><!--
body{margin-top:1;background-color:#000;}
a.type3:link    {color:#FF8000; text-decoration:none;}
a.type3:visited {color:#FF8000; text-decoration:none;}
a.type3:active  {color:#FF8000; text-decoration:none;}
a.type3:hover   {color:#00CCFF; text-decoration:overline underline;}
//--></style>


<script language=javascript>
<!--
function checkres()
{
    ...check resolution....

    if(screenresolution800x600)
    {
       <h3 style="font-family: Arial; font-size: 12pt;">
    }
    else
    {
       <h3 style="font-family: Arial; font-size: 10pt;">
    }
}


<body onload="checkres()">

set a class on your <body> element depending on the resolution:

if(screenresolution800x600) {
  document.body.className = "Resolution800";
}

Then add these rules in you stylesheet:

h3 {
  font-size: 12px;
}
body.Resolution800 h3 {
  font-size: 10px;
}

Note that "pt" is for printed medium, for screen you should use "em" or "px", or (even better) use percentages.

 

by: baumliPosted on 2005-09-18 at 07:29:19ID: 14907005

I understand where to put the rules in the stylesheet, but I'm not sure where to put the other part of your code.  Can you insert the class code in my code above?

 

by: GrandSchtroumpfPosted on 2005-09-18 at 07:58:26ID: 14907094

<script language=javascript>
<!--
function checkres()
{
    ...check resolution....

    if(screenresolution800x600)
    {
        document.body.className = "Resolution800";
    }
}

 

by: apurvabevinPosted on 2005-09-18 at 08:35:49ID: 14907198

This is the method I recommend, where depending on the resolution, the javascript loads a particular stylesheet.

The 2 stylesheets are called "style800below.css" and "style1024below.css". For styles common to both resolutions, you can put the formatting style code directly between the <style type="text/css"></style> tags instead of having to include them in both CSS files. CSS files contain the style code ONLY and must *not* contain HTML tags, that includes <style></style> tags.

If you choose to accept this solution, please divide the points equally between GrandSchtroumpf and me. Thanks.

I think you completely lost me on that one, I don't want external style sheets, I just want everything right here in the code.

 

by: apurvabevinPosted on 2005-09-19 at 19:27:48ID: 14917128

The reason I suggested external stylesheets is because it will save the visitor loading time and also bandwidth for your site.

Anyway, for the method suggested by GrandSchtroumpf, this is what you need:

<head>
<title>...</title>
<style type="text/css"><!--
body{margin-top:1px;background-color:#000;}
a.type3:link    {color:#FF8000; text-decoration:none;}
a.type3:visited {color:#FF8000; text-decoration:none;}
a.type3:active  {color:#FF8000; text-decoration:none;}
a.type3:hover   {color:#00CCFF; text-decoration:overline underline;}
h3{font-size:12px;}/* 1024x768 above */
body.s1 h3{font-size:10px;}/* 800x600 below */
//--></style>

</head>

<body>

<script language="javascript"><!--
if(screen.width<=800){//800x600 or below
document.body.className='s1';
}
//--></script>

<div style="text-align:center;">

First of all, you should create pages that are resolution independent.

But if you still feel you need to cutomize a page, SCREEN SIZE IS IRRELEVANT.  Base it on browser window width.  For example, my screen width is 1600 pixels, but I have my browser window only taking up 800 pixels, just half that space.
