Recently, I've been working on designing a website layout using CSS-Grid. Everything seems to be functioning properly and adapting well to different screen sizes until I encountered an issue with scroll bars appearing at very small resolutions. This causes the css-grid to stop stretching over the entire page height, leaving a blank white space at the bottom.
If you want to visualize this problem, try running the provided snippet in a low-height window. In addition, I have included screenshots of how it appears on my browser for reference.
How it looks at normal height:
What happens when the height is reduced:
I attempted adjusting the overflow and min-height properties but was unable to resolve the issue completely. While not critical, I am curious to understand why it occurs. Thank you!
