html, css, JS, mobile first, responsive, flex, grid, form validation

Thanks for taking a look! There were a couple of things I wasn't able to achieve this time: I wasn't able to get the exact same glyph icon, nor was I able to make the text cursor/caret thicker like the example, any idea how to approach that?

My formValidator function feels kinda repetitive, any suggestions for how to make those lines a bit dryer?

Also, are there any considerations for why the event listener should be on the button or the form?

Also happy to take any general feedback.
