FORMATTING
Basic Formatting should not cause any problems as it is identical to formatting in a Word document. If you hover over each icon it will show a tooltip explaining what each button does.
TEXT STYLE
This dropdown menu should be used to keep formatting consistent throughout the website. For example, if you want to creating a sub heading in a page simply type the text, highlight it and select Heading 3 - the text will always look the same.
It has implications for search as well. Heading 1 should only be used for the welcome message title on the home page. Everything else (ideally) should be heading 2 or 3 (they are the most popular).
HORIZONTAL LINES
Use the button depicted below to create a a line across the page. Using a long string of hyphens (-) or underscores (_) can cause problems with formatting.
PROBLEMS
If you experience problems with the formatting or the text is not "behaving" in an expected fashion then you will have either pasted content from another website or from Microsoft Word. When you do this the superfluous formatting is pasted as well - and this is what causes the problems. To fix it, simply press the WORD CLEANER icon depicted below. This will remove the problematic formatting and everything should work as expected.
You must SAVE the webpage in the editor before the changes will show.
