Question

That would look like:

#div1 #div2
  #div3  

I tried to set #div1 and #div2 to float left, but some part of #div3 come to top. What’ the problem here?

Answer 1

<div id="one"></div><div id="two"></div>
<div class="clear"></div>
<div id="three"></div>


<style>
#one {
float:left
}

#two {
float:left
}

.clear {
clear:both;

}


</style>
