The habits you are seeing with the elevation: automobile and also size: automobile homes results from the manner in which the CSS format engine determines the measurements of components.
When an aspect has a placement worth of outright, its measurements are determined based upon its web content, no matter whether elevation or size are readied to automobile. This indicates that if an aspect with placement: outright has a youngster aspect with taken care of measurements, the moms and dad aspect will certainly handle those measurements also.
On the various other hand, when an aspect has a placement worth of family member, its measurements are determined in a different way. If an aspect has a size worth of automobile, the aspect will certainly extend to load the offered room in the moms and dad aspect. If an aspect has an elevation worth of automobile, the aspect will certainly handle the elevation of its web content, as you observed.
In your instance, the.an aspect has a placement worth of family member and also both elevation and also size are readied to automobile. This triggers the.an aspect to extend fully size of the moms and dad aspect (in this situation, the viewport) and also handle the elevation of its web content, which is the.b aspect. The.b aspect, on the various other hand, has actually taken care of measurements of 50px x 50px, so it does not extend to load the moms and dad aspect.
I wish this aids to improve the habits you are seeing with elevation: automobile and also size: automobile.
