Don't show highlight rectangle on button press

[gbh_uk]

Try adding the following CSS rules in moode.css immediately after the first body rule:

button, textarea, input, select, a {
-webkit-tap-highlight-color: rgba(0, 0, 0, 0);
-webkit-tap-highlight-color: transparent;
-webkit-touch-callout: none;
-webkit-user-select: none;
-khtml-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
user-select: none;
}
:focus {
outline: none !important;
}

This stopped the blue rectangle appearing for me in Chrome for Android.
