Ave - Sticky Rows
Ave includes a unique row system called "Stacks". This feature is similar to Page Blocks but it doesn't include Page Transitions that you see in the Page Blocks. You can create one or multi-page websites with this feature.
Let's see an example of this system:

Page Stacks use the Sticky Rows to create the "overlapping" effect. Simply open the "Row Settings" and enable the "Sticky Row" option.
You can also enable "Fade on Scroll" option if you want to add the ghost effect to the previous row. You can repeat this process for the other rows.
