Content management system

I have tried so to write some html and css pages but I don’t know how can I managed those contents!!!and I want to use those pages I created as “template” to manage my website… As I used to do in wordpress CMS with MY PREVIOUS WEBSITE…
need advice pleez

The templates are just to generate HTML, and CSS is separate anyway. So exact same thing applies, except you replace static text with dynamic

<h1><?php bloginfo('name'); ?></h1>

Instead of

<h1>Some Title</h1>
