css - remove grey background on link clicked in ios safari / chrome / firefox

Question

When you click (touch) a link in Safari (or chrome or firefox) for iOS, you get a grey background behind link (only while you're holding it). Is there a way to remove this feature using CSS?

Please see the example image below:

Answer 1

Webkit has a specific style property for that: -webkit-tap-highlight-color.

Copied from: http://davidwalsh.name/mobile-highlight-color—

/* light blue at 80% opacity */
html {
    -webkit-tap-highlight-color: rgba(201, 224, 253, 0.8);
}

/* change it for a div that has a similar background-color to the light blue tap color */
.blueDiv {
    -webkit-tap-highlight-color: rgba(251, 185, 250, 0.9);
}

If you want to remove the highlight completely—

.myButton {
    -webkit-tap-highlight-color: rgba(0, 0, 0, 0);
}
