code snippet – contact form

Hello,

I’m new to code snippets plugin and trying to get my feet wet by creating a simple contact form with HTML/CSS/JavaScript and PHP (Send email with fields from contact form). I’m using Elementor so the only way to add contact form would be adding a shortcode on the page.

I’ve looked but I can’t see any user documentation on how to have HTML, CSS, JavaScript and PHP all working together using code snippets plugin. Ideally I’d like to have frontend and backend code as separate snippets.

Any help would be much appreciated.

Thanks.
