What does the term "% element height" refer to?

The term "% element height" specifically pertains to the height of the element being viewed in relation to the overall image height. This means that when discussing the layout or composition of visual content—such as a video or presentation—this measurement provides context about how much of the total image height is occupied by a particular element. This is particularly useful for ensuring that important information or visuals are appropriately sized and positioned within the overall frame, maintaining visual balance and coherence in audiovisual design.

For instance, if a video element is set to 50% element height, it indicates that this particular element takes up half of the total height of the image being projected. This ratio is crucial for designers and integrators in planning layouts that are aesthetically pleasing and effectively convey information to the audience.
