At start, this is general question without sample code, as i'm looking for a idea, how to archive this:
I have 3 absolute positioned elements, which overlaps each other. They all have background color, for example red.
Now, div1 overlaps div2, so they have common area, and user is unable to see when first div ends, and secod starts...
As i draw on image below, i may chage opacity of this divs, so user can see some diffrence, but this may be not 100% good solution.
My question is, does anybody have ideas, how make this more readable, maybe some css features, which i don't know about (background color mixing or something...)
Thank you for ideas :)
