HTML-CSS position problem with div

I got a little problem and nothing I test seems to work.

My HTML:

<div id="parent">
    <div id="top_parent开发者_开发百科">Top_background
        <div id="top">Top_Picture</div></div>
    <div id="content">Here comes random stuff<div>
        </div>

        <div id="bottom">Footer</div>

CSS:

#top_parent {
    background:#f00;
    height:100px;
}

#top{
    background:#0f0;
    float:right;
    position:relative;   
    height:100px;
    width:50%;
}
#content{
    top:-50px;
    background:#00f;
    <!--   position:relative;-->
    height:100px;
    width:80%;
    margin:auto;
}
#parent{
    background:#000;
    height:350px;
    width:100%; 
}

#bottom {
    height: 50px;
    background:#ff0;
    bottom:0px;
    <!--position:absolute; -->
    <!--position:relative; -->
}

Now my problem is, the footer won't get under the parent div, it stays in the content area. What am I doing wrong?

Thanks for the help.

You have not closed this div:

<div id="content">Here comes random stuff<div>

Should be:

<div id="content">Here comes random stuff</div>

You could see this easily if you indented your divs:

<div id="parent">
  <div id="top_parent">Top_background
    <div id="top">Top_Picture</div>
  </div>
  <div id="content">Here comes random stuff<div> <!-- Can see the problem -->
</div>
<div id="bottom">Footer</div>

Not sure if you copy-pasted or if this is a typo when you posted your code, but this line:

<div id="content">Here comes random stuff<div>

Should have a closing </div> tag at the end instead of that opening <div> tag. If that's actually your HTML, then it would not be grouping the divs the way you want/expect.

I think you have a wrong html:

<div id="parent">
    <div id="top_parent">Top_background
        <div id="top">Top_Picture</div></div>
    <div id="content">Here comes random stuff<div>
        </div>

        <div id="bottom">Footer</div>

You didn't close div parent, nor content

<div id="parent">
    <div id="top_parent">Top_background
        <div id="top">Top_Picture</div>
    </div>
    <div id="content">Here comes random stuff</div>
    <div id="bottom">Footer</div>
</div>

Interpreting that you want the "bottom" div inside the "parent", else:

<div id="parent">
    <div id="top_parent">Top_background
        <div id="top">Top_Picture</div>
    </div>
    <div id="content">Here comes random stuff</div>
</div>    
<div id="bottom">Footer</div>

Also, in your css you should enable the position:relative for #content div, else the top parameter won't work. Try if this solves the problem.

In order to position footer after the content divs you have to float content divs first and then add clear:both css command to the footer. So your tree sould look like this:::

<div class="wrapper"><div class="left"></div><div class="right"></div><br clear="all" /><div class="footer"></div>

For this example your css should be as following:::

div.wrapper{ width:80%;
position:relative;
margin:0 auto;
}

div.left{ float:left;
width:60%;
background:green;
height:200px; /height only for testing so you could see the result/ }

div.right{ float:right;
width:30%;
background:red;
height:200px; /height only for testing so you could see the result/ }

div.footer{ clear:both;
height:40px;/height only for testing so you could see the result/ background:yellow;
width:100%;
}

Have you tried taking out that "bottom" attribute in the #bottom rule?
