Change Mobile Safari Highlight Color with CSS

I love the amount of extra customization afforded to us by WebKit. That also makes me love the fact that, for the most part, WebKit Mobile is the choice renderer used by mobile devices. One rarely used style property is -webkit-tap-highlight-color, which allows developers to change the default tap highlight color. Here's how to use it!

The CSS

/* 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);
}

Changing the -webkit-tap-highlight-color property value is the key! Also note that using RGBA color allows the extra dimension opacity for the highlight so that the color isn't so harsh.

In the case that you have an element which you'd prefer wasn't highlighted at all, you would code:

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

-webkit-tap-highlight-color obviously isn't a crucial property to change with each site but it's nice to have the ability to change the tap color, especially if you're using dark-colored backgrounds.
