The dark shade (not black, dark grey) it's perfect, but has a weird "shape" in "translation" placeholder that's making that box with rounded up corners. You will see!

I just don't understand why google still didn't include the dark mode option in all it's products, so thank you so much for this solution for now

It works, but u can't see the buttons.

Hace un buen trabajo para lo básico. El problema es que hace la página demasiado oscura y todos los botones de función (como intercambiar idiomas, escuchar, copiar, etc.) son imposibles de ver.

It does the job perfectly in a simple way

Co prawda jest ciemny kolor, ale wszystko zlane z tłem. Poprawić i będzie 5*
