Disable Scrolling on Body
Set height and overflow:
html, body {margin: 0; height: 100%; overflow: hidden}

This post was helpful, but just wanted to share a slight alternative that may help others:
Setting max-height instead of height also does the trick. In my case, I'm disabling scrolling based on a class toggle. Setting .someContainer {height: 100%; overflow: hidden;} when the container's height is smaller than that of the viewport would stretch the container, which wouldn't be what you'd want. Setting max-height accounts for this, but if the container's height is greater than the viewport's when the content changes, still disables scrolling.
HTML css works fine if body tag does nothing you can write as well
<body scroll="no" style="overflow: hidden">
In this case overriding should be on the body tag, it is easier to control but sometimes gives headaches.
