Rulers as a measuring tool
The most obvious role for rulers is as a measuring tool. As you move the mouse
pointer, small lines along each ruler display the current horizontal and vertical
cursor position. When you click to select an object, blue ruler regions indicate
the object's left, right, top, and bottom edges. Each region has a zero point
relative to the object's upper left corner, so you can see the object's dimensions
at a glance.
Using the dot grid
The dot grid is a matrix of dots or lines based on ruler units,
covering the page and pasteboard areas. Like ruler guides, it's
handy for both visual alignment and snapping.
To turn the dot grid on and off:
• Enable (or disable) the Dot Grid button on the View menu.
You can also set the grid spacing, style, and color via the Options dialog.
Setting site properties
Site properties allow settings to be made which will be applied across the entire
site. Default page settings, HTML output control, search engine optimization,
author/copyright, and web usage statistical information can all be set via the
multi-tab Site Properties dialog. Generally speaking, decide on your Site
property settings when you are planning your site—once set, the settings do not
normally need to be modified (although you can at any time).
