CSS using <div> - css

Question

I am using <div> to create a horizontal bar across the screen. Within that horizontal bar, I have 3 more <div> each of a different width. They are supposed to be all in a row horizontally next to each other. Instead, they are on top of each other. How do I fix this?
Also, if I don't have any text within the <div> in my HTML code, the <div> does not appear. Ex: <div>anything</div>

Answer 1

You can add css float:left to div and If you also don't want any text in div you should add css height to div.
.horizon div{
float: left;
height: 20px;
}
like this http://jsfiddle.net/KG5B3/

Answer 2

Just use a float, which IS cross-browser compliant. Also you should clear your floats which can be seen on the updated JsFiddle
.horizon div{
float: left;
}

You can float those inner DIVs. You can also use inline-block (not shown).
<div class="horizon">
<div class="left">left</div>
<div class="mid">middle</div>
<div class="right">right</div>
<br style="clear: both" />
</div>
body {
margin: 0;
}
.horizon {
background: #000000;
width: 100%;
}
div.horizon div {
float: left;
}
.right {
width: 25%;
background: #ff0000;
}
.mid {
width: 50%;
background: #00ff00;
}
.left {
width: 25%;
background: #0000ff;
}
