  text-transform: uppercase;
}

.lowercase {
  text-transform: lowercase;
}

.capitalize {
  text-transform: capitalize;
}

<input class="uppercase" />
<input class="lowercase" />
<input class="capitalize" />

Use css.

Answer 2

You can use @guradio css and just uppercase results on form submit on serverside or with JavaScript before submit.

Or just read https://github.com/RobinHerbots/Inputmask there examples, you can use regexp to limit only to uppercase letters.
