Space between two div tags

Hi I'm trying to set a space between two div tags but I don't know how to do it, I've been searching but I don't understand the examples that I've found

Here's the CSS code:

#logo{
    position:absolute;
    top:160px;
    left:65px;
}
#desc{
    position:relative;
    margin-top:290px;
    left:65px;
}
#desc_entry{
    position:relative;
    margin-top:5px;
    left:65px;
}
.pressed {
    color:#999;
    padding: 10px;
    background: #111;
    border: 1px solid #000;
    border-right: 1px solid #353535;
    border-bottom: 1px solid #35353开发者_如何学Python5;
    -webkit-border-radius: 5px;
    -moz-border-radius: 5px;
    border-radius: 5px;
}

this is the only way I've managed to get a separation between the div tags but the problem is that because I'm using the pressed class it fills the div with this style like this http://i54.tinypic.com/uoux0.jpg And i don't want it to be all filled. Any thoughts?

like other people said, you need to post the html or at least say what element do you want to add space to. This being said, I bet what you need is some clear:both somewhere, because that's the most common mistake on people starting with CSS
