Site builders who are comfortable editing HTML directly can add expanding/collapsing (accordion) content sections (the expand/collapse functionality is used on this very page!) to any content page or text widget.
Using headings properly can help in creating a semantic, organized structure to your content. If your page content has a lot of sections, each with its own subtitle, you should consider using "headings" instead of simply applying "Bold" or using CAPITAL LETTERS for your section titles.
If desired, Site Builders can edit the content of page directly in the HTML. If you are comfortable using basic HTML, feel free to use this option. Important note: Some HTML tags and attributes are filtered out, so not everything that you might type into the HTML editor will appear on the page.
To edit the HTML of a page, select the "HTML" button from the editing toolbar.
