I'm building a web app, but after a click on a button, or at least a clickable object, it gets a blue overlay, like a text selection, but on the object. This only happens on touch devices, not on my desktop machine.

It's built with HTML and CSS, so I hope someone knows an appropriate solution for this.

It took me about 20 screenshots, since this overlay is only visible for less than half a second. For those wondering what I actually mean; check this pic. I've tested this on an iPhone (5) and an Android (Nexus 5) and both (although colors differ) appear to have this visual effect. It's either a HTML thing or device-native thing. One thing for sure: It can be set off, since I've never seen this in a regular app. Note: This happens with any clickable item, not just text links.
