Can you please start to describe more detailed what u want? Draw a sketch or something else… Your information is horrible. What are you expecting to happen? Should the tabs be at the end of the page and should be visible if scrolled or is the content just to large?
Can you please share a project for people to look at? We cannot guess what is happening here, we need something to inspect. If you can’t share your project, you can always try to recreate the issue in a new project and push that to github.
I know this is an old post, but I am facing the same issue and I think it is pretty clear what the issue is based on the OP. When you scroll to the bottom of the page, the tab bar is on top of the content and you cannot scroll any further, therefore the content is being hidden by the tab bar. You can clearly see in the image the button is being cutoff by the tab bar and my assumption is that you cannot scroll down more to see the whole button.
I am facing the same issue trying to create a semi-transparent tab bar:
I have a block button at the bottom of my page and I cannot see the button because it is behind the tab bar. If this was ever resolved, please share your solution.
