and so on

and i have a php script linked to that html page with:

if blablabla {

change background color;
}

does anyone know how to change the background color of my page if the conditions in the if statement are met?

I hope i made this clear, if not, please say which bit is unclear.

Thanks for any help in advance

put your tag inside the if else

if blablabla {

 echo '';
}
else {
 echo '';
}

It's not necessarily great practice, but it should get the job done:

if [ your_conditional ] {
  $styleBlock = sprintf['
    
       body {
         background-color:%s
       }
    
  ', $yourColor];
  echo $styleBlock;
}

One good [?] thing about this is that with this technique, you can put your if statement anywhere - it'll act on the body tag regardless of where you put it.

One caution: if you have additional style rules for the body tag's background color farther down your page, those will take precedence over the one from your if statement.
