I have the following code below however am confused as to why the div element rightnav appears below the div element leftnav if I apply a width property to it. What am I doing wrong or have I misunderstood the use of floats?
CODE

padding: 0px;

font-size: 100%;
}
#content {
width: 700px;
margin-top: 20px;
margin-right: auto;
margin-bottom: 0px;
margin-left: auto;
}
#leftnav {
float: left;
width: 200px;
border-width: 1px;
border-color: #000000;
border-style: solid;
}
#rightnav {
border-width: 1px;
border-color: #000000;
border-style: solid;
}
</style>
</head>
<body>
<div id="container">
<div id="content">
<div id="leftnav">left nav</div>
<div id="rightnav">right nav</div>
</div>
</div>
</body>
</html>
Output
Now if I amend the code as follows by applying the property width to the declaration rightnav, the element appears below leftnav. I thought that it may have to do with the width of the div element content however there is sufficient width with the combination of both div elements i.e. 200px + 200px < 700px

In your first example, #rightnav is not floating, but it stays at the right because it hasn't a clear:left; rule. See here: http://jsfiddle.net/5sHdg/
In your second example, when you specify a width for #rightnav, the browser has a explicit rule about the div's size, so it renders it as a block element should. But it doesn't float next to #leftnav because it lacks a float:left; rule. See here: http://jsfiddle.net/Br4Lm/
So rememeber:
div that needs to be positioned besides another one, thus overriding it's block element appearance.div element below divs that re floating, be sure to include clear:both; (left, right, or both);

Adding overflow: hidden to #rightnav will solve your problem. http://jsfiddle.net/Wexcode/gCVaz/
