I would like to format a title in the middle of a page to reflect the Sydney theme formatting (i.e. centered, with a small red line under it). How can i easily due this from the visual editor? I figured out how to do it with a widget title, but unfortunately the widget is causing a conflict on other pages. It would be great if i could just change one of the header formats to allow this formatting. Below is what I am looking to create, but make that format available whenever i need it.
