Remove Check Box blue border [duplicate]

题

I've created CheckBox with ios style:

<form>
<input id="ckbx" type="checkbox"  value="map_one">
</form>

Ive tried to remove the blue border that created when clicked the button, without success.

plz help me to remove it.

解决方案

use outline:0 this will remove the blue boarder

    input[type="checkbox"]:focus{
        outline:0;
    }
