Next Dreamweaver layers are built upon the foundation of CSS positioning. Type Determines whether an element can be positioned absolutely or relatively on a page. The third option, static, does not enable positioning. Visibility Determines whether the element is visible or hidden, or inherits the property from its parent. Z-Index Sets the apparent depth of a positioned element.
Higher values are closer to the top.
Overflow Specifies how the element is displayed when it's larger than the dimensions of the element. Placement Sets the styled element's placement with the left and top attributes, and the dimensions with the width and height attributes. Clip Sets the visible portion of the element through the top, right, bottom, and left attributes.
