[解決済み] Align <div> elements side by side

Question

I know this is a rather simple question, but I can't figure it out for the life of me. I have two links which I've applied a background image to. Here's what it currently looks like (apologies for the shadow, just a rough sketch of a button):

However, I want those two buttons to be side by side. I can't really figure out what needs to be done with the alignment.

Here's the HTML

<div id="dB"}>
    <a href="http://notareallink.com" title="Download" id="buyButton">Download</a> 
</div>
<div id="gB">
    <a href="#" title="Gallery" onclick="$j('#galleryDiv').toggle('slow');return false;" id="galleryButton">Gallery</a>     
</div>

Here's the CSS

#buyButton {
    background: url("assets/buy.png") 0 0 no-repeat;
    display:block;
    height:80px;
    width:232px;
     text-indent:-9999px;
}
#buyButton:hover{
width: 232px;
height: 80px;
background-position: -232px 0;
}
#buyButton:active {
width: 232px;
height: 80px;
background-position: -464px 0;
}

#galleryButton {
    background: url("images/galleryButton.png") 0 0 no-repeat;
    display:block;
    height:80px;
    width:230px;
     text-indent:-9999px;
}
#galleryButton:hover{
width: 230px;
height: 80px;
background-position: -230px 0;
}
#galleryButton:active {
width: 230px;
height: 80px;
background-position: -460px 0;
}

How to solved?

適用 float:left; を追加すると、2つのdivが並んで表示されるようになります。
