There are two ways to edit HTML: using WYSIWYG editor or using code editor. There are two WYSIWYG modes available: quick edit and HTML edit. To open a quick edit mode simply double click on text or select first option from the layout options menu. When you select and edit text a small menu with editing options will popup. You can close editing mode by clicking “Close quick edit” button.
To open a full HTML editor select second option “Open HTML editor” from the layout options menu.
Text will now open in a HTML editor with various editing options.
From HTML editor you can open code editor by clicking on “Code view” button.
Now you can edit html code directly.
You can close code edit by clicking the same button you opened it with and you can close HTML editor by clicking “Close editor” button.
