I need a div in a div sorted

[noelthefish]

At the moment I have a Div in a Div within a container div. now the effect I am looking for is shown here.

What I have at the moment is shown here.

Which bit of the CSS did I get wrong. I will put code up here if it helps but I think that it is something really simple that I am missing as the background colour seems to be bleeding out.

Thanks

Noel.

Can you post your existing HTML - it be easier to figure out what is happening

ok here is the code.

I have just put it into html file.

<div class="driver">
    <div class="info">
    </div>
    <div class="dropzone">
    </div>
</div>

and css file

.driver{
   position: relative;
   float: left;
   left: 1px;
   width: 530px;
   height:120px;
   margin-bottom: 1px;
    -webkit-border-radius: 10px;
    -moz-border-radius: 10px;
    border-radius: 10px;
    padding: 1px;
    margin-top: 1px;
    margin-right: 1px;
    margin-bottom: 1px;
    margin-left: 1px;
background: rgba(255, 0, 0, 0.6)
}
.info{
   /*position: relative;*/
   float: left;
   left: 1px;
   width: 400px;
   height: 120px;
   line-height:12px;
   font-size:12px;
   background-color: rgba(255,0,0,0.5);
}
.dropzone{
   position: relative;
   float: left;
   left:1px;
    width: 130px;
    height: 65px;
    box-shadow: 0 0 10px #999;
    overflow: hidden;
    -webkit-border-radius: 10px;
    -moz-border-radius: 10px;
    border-radius: 10px;
    padding: 1px;
    margin-top: 1px;
    margin-right: 1px;
    margin-bottom: 1px;
    margin-left: 1px;
background-color: rgba(255,255,255,0.1);
}

All your divs are floating left... W3 Schools Float It looks to me like you have an outer div Driver, with two inner divs info and drop zone because the inner divs are both left floating they will be both trying to be on the left hand side of the outer div both with a starting point of 1 px relative to their parent Div I'm not sure if the browser would try and Stack the DIVs over each other also I've always specified color by name or Hex code so not sure what colors you are using (Decimal values in an RGB?)
