QuarkXPress versions 7.0 and earlier included a feature called Baseline Grid. The baseline grid was an evenly spaced series of invisible horizontal lines running from the top to the bottom of each page. Locking paragraphs to the baseline grid let you align baselines from column to column and from box to box, across a page and across spreads.

In QuarkXPress 8.0, the Baseline Grid feature has been replaced by the Design Grid feature. For more information, see “Working with design grids.”
