These files Are examples only of CSS and Javascript techniques that you can use in your own work. I have deliberately put very little effort into making the examples attractive, so as to not confuse the important elements. You should be able to incorporate these techniques into your own designs and add your own styles.
I have left the CSS styles in the head of each document, again for ease
of learning, but this is not the best solution for a live site.
Old browsers like NN4.x do not render some styles properly if at all
so I hide all styles from these browsers by keeping all CSS in a separate
file. I can then use @import to link to these CSS files. Old browsers don’t
understand @import so the styles are not imported and they display
plain HTML. Because these browsers don’t use the CSS styles I hide the Javascript
functions from them too by checking for getElementById(), new browsers will
understand this function and execute the script, old browsers won’t.
<style type="text/css">
@import url("path/to/css/file.css");
</style>
<script type="text/javascript">
if (document.getElementById) {
//execute this script
}
</script>
