To create and add a button to your content, you need to make sure you created a style for buttons in Content Design System Manager. If you already have styles for your buttons, you can add a button in Side Toolbar.
For every button, you can choose:
Its name (you can create several buttons inside your style).
Text format for your text on the button.
Border width and radius.
Colors for text, border, and background for the different button states.
Default (before interaction with this button), on hover and click.
You can add a button to a post from the Side Toolbar
In the Upper Contextual Menu, you can edit various settings for your buttons. Here is what you can do:
Choose the button style.
Change the button’s bottom indent.
Choose where the button will lead to (URL or anchor).
You can also set a telephone number instead of URL — enter tel:5555555555 in the URL field.
Set an animation.
Set the visibility for different types of devices.
