How to display content

Hi, I am slowly getting the hang of WP, but I’m still at very beginner’s stage. I have learnt how to create my own custom theme and make new pages, but now my problem is, whenever I go to Dashboard Admin->Page to edit a specific page I created, I enter some text and Publish. But when I check my locally hosted wordpress site, the div content (the content class selector in my style.css) still shows nothing. What am I missing? I don’t know the WP function to pull the content from the WP database whenever I enter some text in a certain page.

Thus far this is what I have:
index.php
=========

<?php get_header(); ?>

<?php get_footer(); ?>

header.php
==========

[code moderated - please use the pastebin]

footer.php
==========

</div><!-- END content-->

	</div><!-- END contentBox (holds div content, div sidebar later-->

</div><!--END container div-->

<div class="footer">
		<h6><?php bloginfo('name')?></h6> powered by WordPress
	</div>

</body>

</html>

Any help appreciated!
