How to align content of my slides to the top in Quarto/revealjs presentation ?

I want to use max space for code and output panels in my Quarto revealjs presentation (qmd file). Especially I am looking for height setting.
How do I do it, please ?
In the following picture there is plenty of space, but I do not know how to expand that window with code. When I go full screen in firefox it does not auto-stretch fully. I am using newest Quarto version, on windows 10, R 4.4.1, Rstudio.
Even when I have got more code in the chunk, there is still not fully used space for better display and readability.
