Hello. I have, or rather am designing a news site, which i want to have a frontend look on the homepage where the to the left of the homepage there is a big, 16:9 article and right next to it two identical square articles, which would ideally be half of the height of the featured article, to fit perfectly to the page.
Is there any way i can find dynamic information regarding the height of an element, so that i can use this to formulate the size of another element?
