Single-page developer portfolio with EmailJS and BEM

What specific areas of your project would you like help with?

I have doubts about the semantics of the code, also about the svg icons in this project.

1. I would like to know if a different code hierarchy is possible in html with design in mind, especially regarding container, section, hr.
2. Are the svg's styled correctly and is this the only way to connect them without using different libraries?
3. When I was working on sending the form to the email, I used EmailJS. I faced the problem that I can't use php at least in Github Pages, are there any free hosting alternatives where this is possible?
4. Could there be a problem with putting a js file with some variables in .gitignore if I'm using GithubPages? There was an attempt, but after that the form stopped working.

I will be glad to receive any other feedback too!
