Is it possible to automatically calculate max-height on css?

Question

css

Good afternoon! Let's say there is such a form, you need the text to occupy the entire remaining height, and if it doesn't fit, a scroll appears.
I know that for this you need to register your own max-height.
But the problem is that the title is... dynamic, and in one case it can take 50px, in another 100px. Therefore, it cannot be calculated.

Of course, you can stretch it with the help of the flex-grow property, but you need max-height.
Maybe someone has come across this and knows a feature how to do it.

Answer 1

try not with pixels, but as a percentage - example - max-height: 10%;

Answer 2

Add a class to the block with the test overflow-y: auto;
