See below.

1. The first example is a Group Heading with content.
2. The second example shows a Group Heading without content.

You should always place a Group Heading above a group of one or more of the following "stackable" content types. A Group Heading does not need to have text, so even if you don’t have an H2 heading to add, you should add a Group Heading above one or more of these.

• Scannable paragraph
• Multicolumn content
• Structured table
• Featured Image/Video

Most content types include their own "Heading" field. If a block includes this field and it isn't one of the "stackable" content types, you don't need to precede it with a Group Heading.

Do

• Place a Group Heading above one or more stackable content types, even if you don't include text in the "Group Heading" field.
• Be brief and clear.
• Use sentence case.

Don't

• Don't include a period at the end of the heading.

Headings

When you use a Group Heading with text, it will appear as a Heading 2 element on the page. The headings within the group of stackable content types below it should start at Heading 3.

When you use a Group Heading without text, all headings within the group of stackable content types below it should start at Heading 2.
