I would like to create a banner similar to the one shown here: https://i.sstatic.net/SZLr9.png
I am attempting to achieve this using 'absolute' or 'fixed' positioning.
However, when I tried using 'left: 0 right: 0 top: 0', it ended up looking like this: https://i.sstatic.net/MXEmZ.png
Alternatively, setting the width to '100%' caused it to shift to the right. How can I position 'A' as shown in the first image? I prefer not to use relative or static positioning as they cause content displacement.
