[css] disable horizontal scroll on mobile web

I've found this answer over here on stackoverflow which works perfectly for me:

use this in style

body {
    overflow-x: hidden;
    width: 100%;
}

Use this in head tag

<meta name="viewport" content="user-scalable=no, width=device-width, initial-scale=1.0" />
<meta name="apple-mobile-web-app-capable" content="yes" />

A slight addition of mine in case your body has padding (to prevent the device from scaling to the body content-box, and thus still adding a horizontal scrollbar):

body {
    overflow-x: hidden;
    width: 100%;
    -webkit-box-sizing: border-box;
       -moz-box-sizing: border-box;
            box-sizing: border-box;
}
