Amaya does not appear to support dynamic positioning attributes such as position: absolute, position: relative and position: fixed. This is unfortunate because these attributes appear to be standards compliant and are increasingly popular with web developers. Refer to http://www.w3schools.com/Css/pr_class_position.asp for details. The positioning attributes can be used in association with top: and left and margin -top margin-left position reference attributes, enabling those elements to be dynamically dragged into position. The z-index attribute then allows elements to be stacked in a desired order one on top of another so that text for example can be displayed above an image. Refer to http://www.w3schools.com/Css/pr_pos_z-index.asp for details. If the dynamic positioning and stacking of attributes were to be permitted within Amaya (currently, Amaya wipes all of these attributes from the code when Code clean up is applied), then dynamic positioning and element stacking should only be available when specially requested by a developer, in order to avoid client users who onlly wist to edit text within a pre designed page cannot accidentally disturb the underlying page design and layout. Within many page editors, dynamic positioning is usually only applied to div tags, although it is possible to successfully apply dynamic positioning attributes to images, tables and other elements within a number of browser based page editors, enabling elements to be easily and intuitively dragged into position within a page, and each elements stacking order can be adjusted where appropriate.
