You can customize the “Flex” wrapper using the Post Grid Combo plugin. This article will help you to style the flex wrapper.
To begin, insert a “Flex Wrap” block.
Then choose a variation. For example, I choose the two columns variation.
Here, you can adjust the justify-content, align-items, flex-direction, and flex-wrap settings to your liking.
Then Click on the Wrapper tab. Here, you can change the wrapper tag to H1, H2, H3, H4, H5, H6, SPAN, DIV, and P tags.
Now click on the style tab and add style to the Flex Wrapper.
