The Card slider is an easy widget to set up and add to a Landing page!
/sitecore/content/Repository/Widgets/Card Slider Widgets
Easy peasy! Add your Title. Add your pages by double-clicking or using the > arrow. Remove by double-clicking or using the < arrow. Rearrange the order by using the up and down buttons.
Add as many items as you want, keeping in mind the first two and the last item in your list are what appear first in the slider. The rest is hidden and will require SLIDING to see them.
