Solution 1:

Yes; just assign 'none' to the 'outline' property:

input {
    outline: none;

I was intending to disable it/modify it to see what it could do.

To adjust the style for the outline you can access the individual properties:

elementSelector:focus {
    outline-width: 4px; /* thin, medium, thick or standard CSS length units */outline-style: auto; /* or 'inherit', 'none' or border-style (solid, dashed, dotted...) */outline-color: #f90; /* standard CSS colors */
}

JS Fiddle demo.

The above can also be condensed, using shorthand notation:

elementSelector:focus {
    outline: 4px auto #f90;
}

The smallest of the possible outline measurements that can be used are either:

elementSelector:focus {
    outline-width: thin; /* or 1px */
}
