After formatting my HTML code as shown below:
https://i.sstatic.net/oaVVg.png
The blue rectangle takes up 70% of the outer container's width, while the green rectangle occupies the remaining 30%.
My goal is to have the blue rectangle expand to fill the entire width of the outer div when the green rectangle is set to display:none. I'm aiming for a layout like this:

Currently, when I hide the green rectangle div, the display looks like this:

Any assistance on achieving this would be greatly appreciated.
