Inner glow effect of button

Question

I want to have inner glow effect of button when focused. I could achieve outline (outer) glow of button but I even want to have inner glow effect. Could anyone help?

Answer 1

I made a jsFiddle showing this effect:

a {
    -webkit-box-shadow: inset 0 0 30px #00f;
    -moz-box-shadow: inset 0 0 30px #00f;
    box-shadow: inset 0 0 30px #00f;
}
