How to remove space between inline-block elements?

Given this HTML:

<p>
    <span> Green </span>
    <span> Red </span>
</p>

and this CSS:

span { 
    display:inline-block;
    width:100px;
}

I have found 2 solutions:

1. Use float:left instead of display:inline-block.
2. Use display:table-cell
