As I work on developing a responsive website, I've encountered an issue where only 50% of the screen is filled with content when viewed in mobile mode, leaving the rest as white space. Can you shed some light on why this might be happening?

In addition to that, I'm struggling to make the background image on my home screen responsive consistently. Sometimes it adapts well, while other times it doesn't. I'm not sure what mistake I might be making in this process.
Your help and insights are greatly appreciated. Thank you in advance.
