Here are three solutions.

The markup:

<div id="outer">
    <div id="a1">1</div>
    <div id="a2">2</div>
    <div id="a3">3</div>
    <div id="a4">4</div>
    <div id="a5">5</div>
    <div id="a6">6</div>
    <div id="a7">7</div>
    <div id="a8">8</div>
    <div id="a9">9</div>
</div>

The basic stylesheet (dimensions and color):

#outer {
    width: 20em;
    height: 20em;
}
#a1 {
    background-color: #C0C0C0;
    width: 80%;
    height: 20%;
}
#a2 {
    background-color: #800000;
    width: 20%;
    height: 80%;
}
#a3 {
    background-color: #000080;
    width: 20%;
    height: 80%;
}
#a4 {
    background-color: #FF0000;
    width: 40%;
    height: 20%;
}
#a5 {
    background-color: #0000FF;
    width: 20%;
    height: 40%;
}
#a6 {
    background-color: #FFFF00;
    width: 20%;
    height: 40%;
}
#a7 {
    background-color: #FFFFFF;
    width: 20%;
    height: 20%;
}
#a8 {
    background-color: #008000;
    width: 40%;
    height: 20%;
}
#a9 {
    background-color: #FFA500;
    height: 20%;
    width: 80%;
}

And now the positioning:

Using float:

#a1 {
    float: left;
}
#a2 {
    float: right;
}
#a3 {
    float: left;
}
#a4 {
    float: left;
}
#a5 {
    float: right;
}
#a6 {
    float: left;
}
#a7 {
    float: left;
}
#a8 {
    float: right;
}
#a9 {
    float: right;
}

Using position:

#outer {
    position: relative;
}
#outer div {
    position: absolute;
}
#a1 {
    top: 0;
    left: 0;
}
#a2 {
    top: 0;
    right: 0;
}
#a3 {
    top: 20%;
    left: 0;
}
#a4 {
    top: 20%;
    left: 20%;
}
#a5 {
    top: 20%;
    right: 20%;
}
#a6 {
    top: 40%;
    left: 20%;
}
#a7 {
    top: 40%;
    left: 40%;
}
#a8 {
    bottom: 20%;
    right: 20%;
}
#a9 {
    bottom: 0;
    right: 0;
}

Using margin:

#a1 {
}
#a2 {
    margin: -20% -80% 0 80%;
}
#a3 {
    margin: -60% 0 0 0;
}
#a4 {
    margin: -80% -20% 0 20%;
}
#a5 {
    margin: -20% -60% 0 60%;
}
#a6 {
    margin: -20% -20% 0 20%;
}
#a7 {
    margin: -40% -40% 0 40%;
}
#a8 {
    margin: 0 -40% 0 40%;
}
#a9 {
    margin: 0 -20% 0 20%;
}

No one here has given a table solution yet, and The Challenge is all about comparing CSS layouts to Table based layouts in a controlled (and heavily biased) scenario.

So here is Ted's Table Layout solution and his challenge...

"With my table based solution, it is very easy to add new inhabitants to the garden plots by very simple additions to the HTML markup only! All inhabitants are automatically centered and spaced in a pleasing style. For example:"

"As far as I can tell, no CSS based solutions here can accomodate new inhabitants without extensive renovations to the CSS rules."

"Better bring lots of money boys, I'm feeling really hungry and thirsty now."

_{(source: sontag.ca)}
I first did this exercise a little over 2 years ago when I was first learning HTML and CSS. My first solution was like the one you see here, except without the anonymous container DIVs. Then I got this idea for a web page that did a side by side comparison of CSS to a Table to prove CSS was better. So I worked on The Challenge page, published it, and then posted this question.

Sam Hasler posted an answer within minutes, it seems, that was really close. I could see he was on track for a better solution than what I had. All his divs were in order, and mine were not. Jacco posted a comment asking why I used two nested tables when one would do. He was right too, of course.

So I had two Homer Simpson "Doh!" moments right away. I read other questions and answers on tables vs. CSS. Someone mentioned that tables centered vertically. My answer did not center vertically either, but I thought it might be possible. The whole point, after all, is to do everything a table can do and better. I had painted myself into a corner by now, looking like a fool, so I had to find an answer.

Eventually (am embarrassed to say how long it was) I came up with the solution below. I was then able to fulfill my original concept of a side-by-side comparison web page.

Here is an explanation of how it all works and why you should use CSS

As long as the widths and heights are constant, one can always use absolute positioning to get the same effect. This should be obvious enough, so that I don't have to type it out (it's late here and I'm lazy :P)

I think we've proved that there's more than one way to do this. The table tag and CSS are both viable options.

Rather than add another way to complete the challenge I'd just like to say that, whether it's easier or harder, simpler or more complex: tables in HTML should be used for displaying tabular data.
- Tables are made for tabular data.
- CSS is made for styling/presentation.
