I have this scroll link that works perfect when I use it at the end of a page but when I place it in another position the final text "montages" to the next section, example of the overlap (the last text): link
I was reviewing the js file and it seems to me that something more must be added, I do not handle much js so I dare to consult by this means.
Thanks for your time.
This is happening to you because the section next to the paralax (where you do not want the text to be mounted), has not assigned any position , and also has no assigned z-index , so everything that is in the rest of the section (that have z-index: 5 ), will be above.
One solution would be to give the section , in which you do not want the text to be mounted, the following CSS rules:
CSS
position: relative;
z-index: 6;
With that you should have solved the problem that has come up.
