When this option is on, an AP element can’t be created in front of, moved or resized over, or nested within an existing

AP element. If you activate this option after creating overlapping AP elements, drag each overlapping AP element to

move it away from other AP elements. Dreamweaver does not automatically fix existing overlapping AP elements in

the page when you enable Prevent AP element Overlaps.

When this option and snapping are enabled, an AP element won’t snap to the grid if it would cause two AP elements

to overlap. Instead, it will snap to the edge of the closest AP element.

Note: CertainactionsallowyoutooverlapAPelementsevenwhenthePreventOverlapsoptionisenabled.Ifyouinsert

an AP element using the Insert menu, enter numbers in the Property inspector, or reposition AP elements by editing the

HTML source code, you can cause AP elements to overlap or nest while this option is enabled. If overlaps happen, drag

overlapping AP elements in the Design view to separate them.

• In the AP Elements panel (Window > AP Elements), select the Prevent Overlaps option.

• In the Document window, select Modify > Arrange > Prevent AP Element Overlaps.

Working with div tags

About working with div tags

You can create page layouts by manually inserting div tags and applying CSS positioning styles to them. A div tag

is a tag that defines logical divisions within the content of a web page. You can use

div tags to center blocks of

content, create column effects, create different areas of color, and much more.

If you’re unfamiliar using

div tags and Cascading Style Sheets (CSS) to create web pages, you can create a CSS layout

based on one of the pre-designed layouts that come with Dreamweaver. If you’re uncomfortable working with CSS,

but are familiar with using tables, you can also try using tables.

Note: Dreamweaver treats all div tags with an absolute position as AP elements (absolutely positioned elements), even

if you didn’t create those div tags using the AP Div drawing tool.
