Struggling to grasp the concepts of padding, margins, and negative margins in CSS, I decided to test my knowledge by creating the following code snippet.
Upon adding a margin to my "row" class, I anticipated that:
- A positive margin-left of 20px would shift my "row" div 20px to the left.
- A negative margin-left of 20px would move my "row" div 20px to the right.
However, the reality turned out quite differently:
- A positive margin-left actually reduced the width of my "row" div by 20px from the left.
- Conversely, a negative margin-left increased the width of my "row" div by 20px to the left.
I suspect this behavior may be due to the fact that my "row" div is nested within the "container" div. Nevertheless, I am unsure why this unexpected result is occurring. Any insights on this matter would be greatly appreciated!
Thank you for your help!
