I make changes in wordpress but nothing changes - html

Question

I am using wordpress to develop a website.
I am using my own html template instead of wordpress themes, which has css file also.
When I try to make some html changes in it through the dashboard of wordpress, it doesn't change.
Why it does not happen?
Is wordpress doesn't support html tags sometimes?
Or is the html tags that I use, clashes with css?
code of index page is here.
<?php get_header(); ?>
<div id="content">
<div id="inner_content">

Do you have any cache plugin installed? I had the same issue where my website wouldn't update. I later found out it was a WP SuperCache plugin issue.
