The new Filemaker 13 comes with the styles and themes feature that allows us to help design our layouts more dynamically than we ever could. We can design better layouts with the new design attributes and make our solutions more consistent by the use of themes.
The styles are set of formats that you can apply to layout objects, layout parts, and the background of a layout.
A Theme is just a collection of Styles. Make your own themes or modify the existing ones and use it over multiple layouts and even import it to other files if used in a multi-file solution.
