Hey Chris,
if you mean the height of the slider – if we set it to a percentage of screen height, it may lead to undesirable consequences on portrait or landscape screens, thus the only way is to use pixels; CSS does not allow to set height in percentage of screen width. There are not strict rules for the @media breakpoints, in this case they’ve been chosen so as to make the website look good on smaller devices with typical screen sizes.
Sincerely,
