Problems with height "detection" in css and html

claell opened this issue · comments

I have been facing problems with the height detection of the viewport.

First time I noticed it was when I used vh instead of px for text size, which behaved different from vw.

Now I tried to apply 100% height to an image. While width works and the image is resized responsive to the width of the widget, the height is constant.

This lead me to think that there is some problem with the detection of the height, but I might be wrong.

You're probably wrong, there is no "height detection" besides what the browser is offering (vw and vh) - vertical positioning is infamously a major pain point in CSS...

("height: 100%" means 100% of the height of the container which might not have a height)

This issue is also really too vague and not actionable, if you want to discuss widget development please use the forum instead: https://community.openhab.org/c/apps-services/habpanel - Thanks!
