Make sure this is wrapped in a p tag or it won't have this gray/white style. Also make sure it is in the same draggable area (layout block) as the image above.
For this style Drag in a content block and click: EDIT > ADVANCED > ENTER "standout-text" in the CssClass field.
Make sure all your paragraphs are wrapped in a paragraph tag <p></p> so that your content is spaced consistently.
