Using horizontal rules
Horizontal rules (lines) are useful for organizing information. On a page, you can visually 
separate text and objects with one or more rules.
To create a horizontal rule:
1.
In the Document window, place the insertion point where you want to insert a horizontal 
rule.
2.
Do one of the following:
Select Insert > HTML > Horizontal Rule.
In the HTML category of the Insert bar, click the Horizontal Rule button. 
To modify a horizontal rule:
1.
In the Document window, select the horizontal rule.
2.
Select Window > Properties to open the Property inspector, and modify the properties as 
desired:
and 
specify the width and height of the rule in pixels or as a percentage of the page 
size.
Align 
specifies the alignment of the rule (Default, Left, Center, or Right). This setting 
applies only if the width of the rule is less than the width of the browser window.
Shading 
specifies whether the rule is drawn with shading. Deselect this option to draw 
the rule in a solid color.
Creating bulleted and numbered lists
You can create numbered (ordered) lists, bulleted (unordered) lists, and definition lists from 
existing text or from new text as you type in the Document window. 
Definition lists do not use leading characters like bullet points or numbers and are often used 
in glossaries or descriptions. Lists can also be nested. Nested lists are lists that contain other 
lists. For example, you might want an ordered or bulleted list nested within another 
numbered or ordered list.
