Baseline grids in InDesign are set on a per-document basis, in preferences. What if I need a different baseline grid somewhere in a document?
Can I override the document baseline grid in one section, frame, page or master page?
For example, you might want a different baseline grid to the rest of a document on a contents page, a references block, or on a master page that is used for a very different type of content e.g. photo spreads with side captions.
