5. In the Style panel, click on the Add class or combo class button (the plus symbol with a square).
6. Give your class a name and hit enter.
7. Now, with the h4 element still selected, click on the black plus button that appears next to the class name you just added.
8. From the dropdown, select Span.
9. A new span element will be added below the h4 tag.
10. With the span element selected, you can add any desired text or further customizations, including adding classes or styling within the span.
11. Once you're done, you can continue editing or styling the h4, span, or any other element on the page.
