Answer 1

use box-shadow :)

This example uses two comma separated shadows:

  box-shadow:0 0 50px gold,0 0 150px gold;

You could draw it with radial-gradient too. Result will varie from browser to browser.

Answer 2

I believe this is what you want:

span:hover {
    -webkit-border-radius: 70px;
    -moz-border-radius: 70px;
    border-radius: 70px;   
    -webkit-box-shadow:0px 0px 10px red;
    -moz-box-shadow: 0px 0px 10px red;
    box-shadow: 0px 0px 10px red;
}

Answer 3

Instead of this style for your box-shadow:

box-shadow: 0 0 0 10px red;

Try this:

box-shadow: 0 0 10px red;

Edit: If you want the glow to be bigger, just increase the radius:

box-shadow: 0 0 30px red;
