z-index and overlapping elements

[mountainsuperstd]

hey there, got a quick question about overlapping elements.
so, I have a lot of text elements here http://modaportugal.pt overlapping project thumbnails (images in other pages).

while updating pages in other sections of the website, the text elements on the left are suddenly all under the elements on the right, which I guess it makes sense because they precede them in the html flow.

but the question is, why are they working this way now and go below when I update the page with a new element?

I also haven't been successful in setting a higher z-index for these elements but I admit that my css is a bit rusty lol

anyway, sorry for the long post and thanks in advance for your help.

cheers

im not sure i understand this sentence

well elements to the right will always overlap elements to the left

you can always right click an element, "set html class and id"
then as "html class" add:

overlapp

then in lay options → custom css & html:

.overlap{
z-index: 10!important;
}

nice website!
