I am trying to move my site to WP using a child theme based on twenty sixteen (this is the first time I am dealing with WP).
Considering my site html and css, is it possible to incorporate html structure and css from my site into child theme and get rid of all ids and selectors which are not used? If so, what would be the first step in this process? Say should I start with tweaking header.php and footer.php considering my markup etc.? What I am trying to achieve is to move all pages of my site to WP and also add a blog page.
I've read quite a few similar topics on this site including how to tweak wp_nav_menu, Codex article on how to create and modify a child theme, Walker class etc. I also read this article How To Create And Customize A WordPress Child Theme however, was unable to get a clear understanding if what I am trying to achieve (please refer to my question above) is possible. I did however gain some general understanding in terms of what is a child theme, how templates work, what is template tags etc.
