  Hi hitch! Great work!

  1 To turn the input into red, you can add a class to the input when error. For example,

   if (numberInput.value.length <= 0) {
  // implement error class in CSS
   numberInput.classList.add("error");
  }
  

  2 To make sure user only input numbers, you can do it with javascript. Here is an example.

  nameInput.addEventListener("change", e => {
  const characterRegex =  /[a-z\s]+/i;
  if ( !characterRegex.test(e.target.value) ) return;
  })

  I hope it helps! Cheers!

  You can make an error class containing the red style and add it to the inputs whenever the input is invalid. You can add class using element.classList.add("errorClassName").
