Section Headers Font / Size / Style

You can change the type of individual containers - visual elements consisting of page elements such as boxes, controls, grids etc. To do this, click on the Containers tab, select the particular container on the page (click on it) and then modify the container parameters. Note that all containers except the active one is displayed in grey color.

Thanks Cristian - but I still don't see a "Header" option under the Style Editor for Sections - when I'm in the Containers tab in the Style Editor and I select the Edit Page, then under "Text" the Header option is listed and I can adjust the font and size. But when I select a "Section" under the Edit Page, the Header option no longer appears under Text (just Plain and Alternative). The Header is also not displayed for the "Section" in the preview (just the Grid). The "Section" Headers also don't appear under the Visual Editor for either the Edit Page or the Section so there's no way to adjust them there either.
Thanks again for any help!
