Preventing layer overlaps

Preventing layer overlaps

Because table cells cannot overlap, Dreamweaver cannot create a table from overlapping layers. If you plan to convert the layers in a document to tables, use the Prevent Overlap option to constrain layer movement and positioning so that layers don’t overlap.

When this option is on, a layer can’t be created in front of, moved or resized over, or nested within an existing layer. If you activate this option after creating overlapping layers, drag each overlapping layer to move it away from other layers. Dreamweaver does not automatically fix existing overlapping layers in the page when you enable Prevent Layer Overlaps.

When this option and snapping are enabled, a layer won’t snap to the grid if it would cause two layers to overlap. Instead, it will snap to the edge of the closest layer.

NOTECertain actions allow you to overlap layers even when the Prevent Overlaps option is enabled. If you insert a layer using the Insert menu, enter numbers in the Property inspector, or reposition layers by editing the HTML source code, you can cause layers to overlap or nest while this option is enabled. If overlaps happen, drag overlapping layers in the Design view to separate them.

To prevent layers from overlapping, do one of the following:

  • In the Layers panel (Window > Layers), select the Prevent Overlaps option.
  • In the Document window, select Modify > Arrange > Prevent Layer Overlaps.
