Margin collapse after relative positioned div


Short story: my footer doesn’t react to margin-top, i’ve tried many various way (well it actualy works on very big numbers, which shows that margin is led from previous element, the image container).Here’s the code:

HTML (i’ve removed content obiviously, and didn’t attach head section, which is before content):

<div id="content">
    <h1 id="top">header</h1>
    <div id="billboard">
        <div id="buttony">
    <div class="pasek">
    <h2 class="naglowek">Najnowsze prace:</h2>

    <div class="photo"><div class="heading"><span>text</span></div><a href="#"><img src="img/thumb1.jpg" alt="smu"/></a><div class="caption"><span>text</span></div></div>
    <div class="photo"><div class="heading"><span>text</span></div><a href="#"><img src="img/thumb2.jpg" alt="smu"/></a><div class="caption"><span>text</span></div></div>
    <div class="photo"><div class="heading"><span>text</span></div><a href="#"><img src="img/thumb3.jpg" alt="smu"/></a><div class="caption"><span>text</span></div></div>

<div id="footer">
    <div id="footerwrap">
    <div class="footerblock"><h3 id="nav">header</h3>
            <li><a href="index.html">link</a></li>
            <li><a href="omnie.html">link</a></li>
            <li><a href="portfolio.html">link</a></li>
            <li><a href="kontakt.html">link</a></li>

    <div class="footerblock"><h3 id="info">header</h3><p>some content </p>
    <div class="footerblock"><h3 id="plus">header</h3>
    <p class="links"><a target="_blank" href="">Smashing Magazine</a></p>
    <p class="links"><a target="_blank" href="">W3 Schools</a></p>
    <p class="links"><a target="_blank" href="">W3 Consortium</a></p>

Here’s the CSS part:

    width: 960px;
    margin: 0 auto;
div#content h1#top{
    font-family: Arial, Helvetica, sans-serif;
    font-weight: 900;

    background-color: #131415;
    background-image: url('img/pasek2.jpg');
    background-repeat: repeat-x;
div#footer div#footerwrap{
    width: 960px;
    margin: 0 auto;
div#footer div.footerblock{
    float: left;
    width: 320px;
    margin-top: 40px;
div.footerblock h3{
    font-family: Impact, Haettenschweiler, "Arial Narrow Bold", sans-serif;
    letter-spacing: 0.1em;
    text-align: center;
    font-size: 24px;
    color: white;
    padding-top: 15px;
    height: 39px;
div.footerblock h3#nav{
    background: url('img/world.jpg') no-repeat 25px;
div.footerblock h3#info{
    background: url('img/info.jpg') no-repeat 25px;
div.footerblock h3#plus{
    background: url('img/chat.jpg') no-repeat 25px;
div.footerblock li{
    font-size: 18px;
    padding: 15px 0 10px 40px;
    margin: 0 20px;
    background: url('img/flash.jpg') no-repeat 10px;
    border-bottom: 1px white solid;
div.footerblock a:hover{
    color: #808080;
div.footerblock p{
    margin: 20px;
    line-height: 20px;
div.footerblock p.links{
    background: url('img/cloud.jpg') no-repeat 10px 0;
    margin: 17px 20px;
div.footerblock p a{
    font-size: 16px;
    color: #636363;
    padding-left: 45px;
    padding-bottom: 6px;
    display: block;
    border-bottom: 1px #636363 solid;

Wasn’t sure which parts of css to drop since as long as suspected parts changes didn’t work for me it could be anything i guess. If it’s too much please tell i’ll drop unnecessary parts.


Here is what you need to do.
Put all the divs in a one display-block container with height specified. See here
