In the settings of Carousel, Layout grid (and others) there is a "Height" parameter, which can take a number of values for the proportion of the screen height (100 vh, 75 vh, and so on).
Question: is it possible to determine the height of an element other than what is in the "Height" drop-down list by adding custom program code (html or CSS)?
Suggestion: Consider setting the viewport share of the screen more flexibly. For example, in my opinion, adding a value of 66% will be very useful, since there is a value of 1/3 vh = 33% vh of the screen and it is logical that there would be a value of 2/3 vh of the screen = 66%. These values are important from the point of view of fulfilling the "Rule of Thirds" (I think everyone knows this rule, but just in case
P. S. Faced the problem of dividing the height of the main screen of the site between the Carousel and below the Layout grid. 75vh is a lot, and 50 vh is not enough for the carousel. I would not like to abandon the percentage division of the height of the vh screen. Therefore, I ask for help from respected experts!
