Detect and display users screen resolution?

Would anyone know any code that would detect the users screen res and display it in a selected position that i select?
keep in mind i am clueless when it comes to code lol

 

You should try out some javascript. This is an example:

<script type="text/javascript">
 
alert("Screen Width x Height: "+screen.width+" x "+screen.height);
 
</script>

Code (markup):

 

Ok cool thanks will that display the res in a desired location on the page?
