Converting between 3.0 and 4.0 browsers

Use the conversion options in the File menu to create a 3.0 browser compatible version of a page that uses layers, or to convert a document that uses tables to one that uses layers. In each case Dreamweaver creates a separate, converted file and preserves the original.

In general, you should perform these conversions only when you are completely satisfied with your original file, since you must repeat the conversion each time you change the original file.

Note: If you want to use layers to lay out a page for use with 3.0 browsers, use the Modify menu Layout commands to convert the current page between table and layer layouts without creating a separate file. See Using layers to design tables.

To convert a file for use with 3.0 browsers:

1	Choose File > Convert > 3.0 Browser Compatible.
2	In the dialog box that appears, choose whether to convert layers to tables, CSS styles to HTML markup (character styles), or both.
3	Click OK.
	Dreamweaver opens the converted file in a new, untitled window. All layers are replaced with a single table that preserves the original positioning.
	Note: Overlapping layers cannot be converted, nor can layers that are off the page to the left or top.
	CSS markup is replaced, where possible, with HTML character styles. Any CSS markup that cannot be converted to HTML is removed. See the CSS to HTML markup conversion table for information on which styles are converted and which are removed.
	Timeline code that animates layers is removed. Timeline code that is unrelated to layers (for example, behaviors or changes to the image source) will execute over time as designed. The timeline is automatically rewound to frame 1.

To convert tables to layers:

	Choose File > Convert > Tables to Layers.
	Dreamweaver opens the converted file in a new, untitled window. Each table cell is converted to a separate layer; empty cells are not converted. Content outside of tables is placed in a single layer. Use behaviors, timelines, and CSS to make your previously static 3.0 page more dynamic and interesting.
