webkit-tap-highlight-color in CSS

 I almost used '-webkit-tap-highlight-color' to remove the blue highlight when you tap an item on a mobile with Chrome.

 My item had an odd shape.

But it seems you also need to set 'outline: none' on recent versions of Chrome. But this causes an accessibility problem.

So I just gave my item a regular shape and kept the blue highlight
