Using Dynamic Layers 409
Creating layers on your page
Dreamweaver allows you to create layers on your page easily and precisely. You can
draw a layer on the page, insert a layer through the menu, or drag it onto your
page. Create as many layers as you need to hold all of your page elements.
You can also create a layer within another layer (nest), put layers on top of each
other (stacking), or hide certain layers while showing others. Use the Layers panel
to easily manage your layers and perform these actions. For more information, see
“About the Layers panel” on page 410.
Each layer that you create in your page has certain default characteristics, such as
tag, visibility, height and width, and so on. To change the default settings, choose
Edit > Preferences and select Layers. For more information about these
characteristics, see “Setting Layers preferences” on page 412.
If you don’t want your layers to overlap each other as you create them on the page,
turn on the Prevent Overlaps option in the Layers panel or choose Modify >
Arrange > Prevent Layer Overlaps. See “Preventing layer overlaps” on page 423.
To create a layer, do one of the following:
•
To draw a layer, click the Draw Layer button in the Objects panel, then drag to
draw the layer in the Document window.
•
To insert a layer, place the insertion point in the Document window where you
want the layer to go and then choose Insert > Layer.
•
To drag and drop a layer, drag the Draw Layer button from the Objects panel
to the Document window.
To draw more than one layer at a time, click the Draw Layer button in the Objects
panel and hold down Control (Windows) or Command (Macintosh) as you draw
out all the layers. You can continue to draw new layers as long as you do not
release the Control key.
If you have Invisible Elements turned on, a layer marker will appear in the
Document window each time you draw a layer on the page. If layer markers aren’t
visible and you want to see them, choose View > Visual Aids > Invisible Elements.
For more information, see “Setting Invisible Elements preferences” on page 156.
