Hello,
I'm using the following javacript that keeps a div always in view. But with different monitor sizes and screen resolutions, I cannot control where the always in view link is going to be. Is there a way to modify this script so that the position is relative, i.e. 25% from the left instead of 200 pixels?

Thanks,

You could change this line to use 25%
el.sP=function(x,y){this.style.left='25%';this.style.top=y+px;};

OK...but what about this line at the end

JSFX_FloatDiv("divTopLeft", 230,500).floatIt();

where 230 is the number of pixels from left, and 500 from top....Should that be changed as well?
