Add css via javascript -

-

hy, maybe stupid question , tottaly easy, can't make work please help. here's code.

asp=height / width * 100; document.getelementbyid("head_wrap").style["padding-top"] = "'+asp+%'";

using alert(asp); gives correct value, made mistake here "'+asp+%'", want value in percentages said doesn't work. help!

you have syntax errors in set value double quotes , single quotes. use property style object, sample:

asp = height / width * 100; document.getelementbyid("head_wrap").style.paddingtop = asp + "%";

alternativally, use did, adjusts in code.

asp = height / width * 100; document.getelementbyid("head_wrap").style["padding-top"] = asp + "%;

i modified jsfiddle, take look here.
