iOS Scrolling prevention

document.ontouchstart = (e) ->
  $pane = $(e.target).closest('.scrollable>div')
  if $pane.length is 0 or $pane[0].scrollHeight <= $pane.innerHeight()
    e.preventDefault()

%ios-scrollable {
  &, >div {
    -webkit-overflow-scrolling: touch;
    overflow: auto;
  }

  >div {
    position: absolute;
    top: 0;
    left: 0;
    right: 0;
    bottom: 0;
  }
}

Relevant in iOS6, but maybe not anymore.

UIWebView optimizations

* {
  -webkit-tap-highlight-color: rgba(0,0,0,0);
  -webkit-user-select: none;                /* disable text select */
  -webkit-touch-callout: none;              /* disable callout, image save panel (popup) */
  -webkit-tap-highlight-color: transparent; /* "turn off" link highlight */
}

a:focus {
  outline: 0; // Firefox (remove border on link click)
}
