Chapter 5: Layout and design
Using visual aids for layout
Note: The user interface has been simplified in Dreamweaver CC and later. As a result, you may not find some of the
options described in this article in Dreamweaver CC and later. For more information, see
this article .
Set rulers
Rulers help you measure, organize, and plan your layout. They can appear on the left and top borders of the page,
marked in pixels, inches, or centimeters.
• To toggle rulers on and off, select View > Rulers > Show.
• To change the origin, drag the ruler-origin icon (at the upper-left corner of the Design view of the Document
window) anywhere on the page.
• To reset the origin to its default position, select View > Rulers > Reset Origin.
• To change the unit of measure, select View > Rulers, and then select Pixels, Inches, or Centimeters.
Set layout guides
Guides are lines that you drag onto the document from the rulers. They help you place and align objects more precisely.
You can also use guides to measure the size of page elements, or emulate the folds (visible areas) of web browsers.
To help you align elements, you can snap elements to guides, and snap guides to elements. (Elements must be absolutely
positioned in order for the snap feature to work.) You can also lock guides to prevent them from being accidentally
moved by another user.
Create a horizontal or vertical guide
1 Drag from the corresponding ruler.
2 Position the guide in the Document window and release the mouse button (reposition the guide by dragging it
again).
Note: By default, guides are recorded as absolute pixel measurements from the top or left side of the document, and are
shown relative to the origin of the ruler. To record the guide as a percentage, press the Shift key while you create or move
the guide.
Show or hide guides
❖ Select View > Guides > Show Guides.
Snap elements to guides
• To snap elements to guides, select View > Guides > Snap to Guides.
• To snap guides to elements, select View > Guides > Guides Snap to Elements.
