When working with HTML, it's important to consider how the size of a child div affects the parent div. If the child div is larger than its parent, scrollbars will appear on the parent div if the appropriate style rules are set.
However, I'm interested in creating a scenario where any attempt to scroll (using arrow keys or making a JavaScript call) results in the child div expanding just enough to allow for the necessary scrolling movement. Essentially, I want the child div to dynamically adjust its size to accommodate the scrolling action without unnecessary expansion beyond what is required.
For example, if a child div is 300px wide within a parent div that is only 200px wide, and I press the right arrow key causing it to scroll 20 pixels to the right, I would like the child div to increase in width by exactly 20 pixels (rather than resizing to match the full width of the parent) and then scroll accordingly.
This approach assumes that there is no way to force a sub-element to scroll within its parent despite being larger. However, I acknowledge that further research may reveal alternative methods to achieve this goal. :)
