site looks horrible on mobile

you're unlikely to get help in DMs, and very likely to get help from sharing anonymized code in open chat. Help in DMs is a much bigger commitment and most people don't make that commitment without knowing you first.

Could you review my website please?

<a> is for links to different pages, <button> is for actions on the same page. And neither allow other interactive element inside of them so nesting them means your site might display unpredictable behavior. It's also bad for accessibility

rest operator | ...

so if you have a function add:

function add(a,b) {
  return a + b;
}

function add(a,b) {
  return a + b;
}

You may want a version to add two, or three, or four, which you can do with the spread operator

function add_rest(...params) {
  let sum = 0;
  for (const val of params) {
    sum += val;
  }
  return sum;
}

function add_rest(...params) {
  let sum = 0;
  for (const val of params) {
    sum += val;
  }
  return sum;
}

You can call add_rest with any number of parameters:

add_rest(1,2); //3
add_rest(1,2,3); //6
add_rest(1,2,3,4,5,6); //something valid, I'm tired.

add_rest(1,2); //3
add_rest(1,2,3); //6
add_rest(1,2,3,4,5,6); //something valid, I'm tired.
