Every Nucleus Card has a corresponding call-to-action that can be customized. This button/call-to-action text appears in a couple of different places.
If your Card is the first card listed in your Homepage List (your Featured Card), the button/call-to-action text will appear in button form as shown below.
If your Card is not the Featured Card on your Homepage, the button/call-to-action text will appear in call-to-action form when a user hovers over the description text of card as shown below.
A Card's button/call-to-action text can be changed within the Nucleus Card Settings. To access Card Settings, click the gear icon at the top of the page while in the Nucleus Card Editor.
Upon clicking the gear icon, you'll notice a new set of options appears in the sidebar. Here, you can begin customizing your Card Settings - including a Card's button text.
When you're ready to to update your Card and commit these changes, click the 'Update' button at the top of the page.
