Adjusting height of strip on mobile

Hi everyone.
I wanted to have my home page strip fill the page on an Ipad, as it does with a PC. I’ve used the code below which has worked beautifully.
However, now the strip is too long on a mobile device (IPhone in this instance). Even though I’ve set the strip to the correct height when I publish the trial page the strip is way too long.
Can I resolve this at all?
Thanks.

$w.onReady( function () {

var style1 = “vh;height:” + 91.00 + “vh” ; //change 86.57 to whatever you calc
$w( “#text20” ).html = “<” + “h1” + " style=" + style1 + “>” + $w( “#text20” ).text + “</” + “h1” + “>” ;
});

I have a similar problem as well, and I have my solution for the PC page was the same code. However, the ability to make a strip height responsive to visitors viewports is something very crucial and surprisingly non existent in Wix. Someone from WIX please respond to this.
