How to make a custom prompt?

Question

css

Hey! I need a custom prompt. I was moving towards a regular modal, but the question arose of how to get the text back from the function that opens the modal. Like a native prompt, only with my appearance. Is it possible to do this somehow?
There is one more option. Open a modal with a field, and when you click on the OK button, do your dirty deeds. But this is somehow ugly, so it is considered as the last option.

var a=window.prompt;
window.prompt = function (message) {
  alert('Начали!');
  return a(message,'сюда вот...');
}

alert('Вы ввели: '+prompt('Введите текст'));
