Master." Using basic Liquid Layout rules: Scale, Recenter, and Based on Master .
All content on the page is treated as a group, and as the page resizes, all the elements scale in proportion. The result is similar to
letterboxing or pillarboxing on HD television screens.
Liquid page rules: Scale
All content on the page is automatically recentered no matter the width. Unlike Scale, the content remains its original size. You can
achieve a similar result to video production safe zones using the Re-center rule with careful planning and layout.
Liquid page rules: Re-center
Guides define a straight line across the page where content can adapt.
Whitespace can be added
Text frames are resized, and the text reflows (but not scale).
Placed image frames are resized and the cropping boundary dimension of the containing frame resizes.
To add a liquid guide, first select the page tool, then pull out the guides from the ruler.
Guide-based rules are similar to 3-slice and 9-slice scaling in Illustrator, Fireworks, and Flash. Watch this video on Applying guide-based Liquid
Layout rules .
To convert a ruler guide to a liquid guide select the page tool and click the Convert to liquid guide icon on the guide. The liquid guide is
displayed as a dashed line, while a ruler guide is a solid line.
