There are two files for wach page to be displayed
(1) the .php file does the preparation of variables and fetches database content... that will all be displayed in the template
(2) the template .html file contains the HTML/CSS page laayout with the variables represented by [var.xxx] -or- [blk.yyy] tags positioned where needed.

If your job entails styling and layout then you just fiddle with the HTML page - without disturbing the bracketed bits.

Look at the http://www.tinybutstrong.com/examples.php to see source code for various ways to do this.
