Nested Positioning: Absolute Within Absolute
Nested absolutely positioned elements can exhibit unexpected behavior in CSS. Consider this scenario:
- A first div (#1st) with position: relative
- A second div (#2nd) absolutely positioned relative to #1st
- A third div (#3rd) absolutely positioned within #2nd
Q: Why is #3rd absolutely positioned relative to #2nd instead of #1st?
A: Because position: absolute within an absolutely positioned element resets the relative position for its children.
This property effectively overrides the relative positioning of #1st for #3rd, making it position absolute relative to its direct parent, #2nd.
To achieve your desired behavior, where #3rd is absolutely positioned relative to #1st, you would need to make #3rd a direct child of #1st.
