 * Hello guys.
 * 1.- I need to optimize webs at theme level: I need to know how to disable functions
   that I am not using in my template to streamline web load time (I don’t want 
   functions that are not used to be called), Is there a way to achieve this?
 * 2-. I need to optimize websites in general: from this I know a lot but at the
   level of plugins, optimization of images, asynchronous loading, implement some
   cache system, minimize CSS and JS files, delete files that are not used following
   a little what marks you the Google PageSpeed or similar web (although sometimes,
   at least, the pageSpeed, it works a bit regular I think).
 * 3.- Modify specific page or posts: I need to know how to modify the pages and
   posts I have in WP but at the code level (HTML, CSS and PHP), I understand that
   WP is calling functions like getTitle, getContent etc, okay, but is there any
   way to see the pages I have in code? I’ve gone through the theme files but there’s
   no way.
 * 4.- In general, learn everything you need at the WP backend level to add functionality
   to the theme, etc.
 * Having said all this, if you can guide me in any way or recommend me some kind
   of course or some kind of learning path I would appreciate it very much.
    At 
   the moment I have bought two udemy courses for 10€ and 12€ with very good ratings,
   more than 24h on development of themes and plugins and well, I’m going to soak
   up info.
 * Thank you! Regards.

 * Not used means not called. There’s nothing to do.

 * You can edit in HTML mode. PHP simply outputs the database entry (HTML and possibly
   CSS).

 * That’s a tall order. There are [Theme Developer Handbook](https://developer.wordpress.org/themes/)
   and [Plugin Developer Handbook](https://developer.wordpress.org/plugins/) and
   [Code Reference](https://developer.wordpress.org/reference). But you should not
   add functionality to a theme. Functionality belongs to plugins. Themes should
   be style and layout only, and able to be switched at any time.
