When using a slideshow, you can now control the alignment of the content for all subsections used.
Navigate to the Editor
Add a Section or tick the Edit icon on an existing Section
The Edit Panel will open
The Slideshow Alignment will place all content (in all subsections) within that Section on the placement selected
i.e. If you choose the 'Top' alignment all content will appear at the top of the page
If you choose the 'Bottom alignment all content will appear at the bottom of the page
The alignment is to allow all content items to be aligned the same.
Points to Note:
If you do not use this feature the default alignment with each subsection will remain
