how to position divs within another div

I want to position divs within another div.

Here's the relevant snippet of css (full example on cssdesk):

        .textblock-container {
            width: 500px;
            height: 500px;
            border: 1px solid red;
        }
        div.textblock {
            width: 100px;
            height: 100px;
            line-height: 100px;
            border: 1px solid black;
            position: absolute;
            text-align: center;             
            background: rgb(0, 150, 0); /* Fall-back for browsers that don't
                                support rgba */
            background: rgba(0, 150, 0, .5);
        }

and the relevant snippet of html:

    <div id='blockdiv1' class='textblock-container'>
        <div id='blockdiv2' class='textblock'><span>foo (NW)</span></div>
        <div id='blockdiv3' class='textblock'><span>bar (NE)</span></div>
        <div id='blockdiv4' class='textblock'><span>baz (SW)</span></div>
        <div id='blockdiv5' class='textblock'><span>quux (SE)</span></div>
    </div>

The problem is that the foo/bar/baz/quux blocks are positioned relative to the browser window, not to their parent element.

What am I doing wrong and how can I fix it?

Unless you add position: relative; to the parent controller the div will be positioned absolute of the window

Try this :

.textblock-container {
width: 500px;
height: 500px;
border: 1px solid red;
position: relative;
}

div.textblock {
width: 100px;
height: 100px;
line-height: 100px;
border: 1px solid black;
position: absolute;
text-align: center;             
background: rgb(0, 150, 0);
background: rgba(0, 150, 0, .5);
}

In fact, you just have to add the position: relative propertie for the parent div.

Add position: relative to the parent .textblock-container div.

Absolutely positioned elements are positioned relative to their nearest positioned parent (e.g. the nearest parent element with a position of absolute or relative), so if they have no explicitly positioned parents (default position is static) they will be relative to the window.
