dynamically generated html doesn't wrap to the screen

I cannot for the life of me figure out why this markup is not wrapping. There's nothing special about it, except that it is generated by javascript. Here's the code. Any thoughts on why it's messing up would be welcome.

I can include the js if you need. but basically it reads the text in the textarea, extracts the words, and creates a list of words.

the style:

<style type="text/css">
#lorem{
    display: block;
    width: 100%;
}
#main{

}
.word{
    margin: 5px;
}
li{
    list-style-type: none;
    display: inline;
}
</style>

and the markup

<div id="header">
    <textarea id="lorem"></textarea>
    <button type="button" id="btn">Create list</button>
</div>
<div id="main">
    <ul>
        <li count="14" style="font-size: 260.294%; top: 200px; left: 100px;" class="word">apple</li>
        <li count="17" style="font-size: 300%; top: 154.03px; left: 184.147px;" class="word">iphone</li>

Looks like it's wrapping. what browser are you using?

Add this rule to your style sheet and the list items will wrap correctly:

#main{
    word-wrap:break-word;
}

This is a variant of the expanding box problem.
