Layout Pattern

Three columns

Place three independent bodies of content beside each other. Keep equivalent comparisons parallel and use fewer columns when content needs more width. Pictures remain visible in full unless an explicit fit overrides the layout default.

How to Use It

Place three independent bodies of content beside each other. Keep equivalent comparisons parallel and use fewer columns when content needs more width. Pictures remain visible in full unless an explicit fit overrides the layout default.

Preview + source

Explore this layout

Set three parallel points side by side; use fewer columns when the content needs more width.

All people, quotations and business figures in these examples are illustrative.

This prepared preview and the OPF describe the same example. Region outlines show measured allocation; toggling them does not change the slide.

Inspect compact default-catalog references. Your host must register the matching catalog; source identifies it without fetching over the network. Copy always includes complete embedded records.

Regions, in reading order

This layout is one list of 4 regions, declared once. The list runs as a column; a split nests a list that runs the other way. Each size is a share of its parent’s width (row) or height (column).

Schematic of the list: each box is drawn in proportion to its size; an auto entry gets a fixed band. Dashed boxes are heading regions.

Column, stacked, top to bottom. No anchor is written on the layout: body regions start at the top unless they set their own.

  1. 1titleauto

    auto, the height the content needs

    Heading region: holds the slide’s title, with its tag and subtitle. It takes a size and no content rules.

  2. SplitRow, side by side, left to right100%

How automatic composition differs

Try dynamic composition

Explore how a text slide reflows as you change its content and shape. These examples use OPF’s shared composition rules; the copied document includes your choices.

Let the content find its spaceStart with the decision. State what the audience should understand or do.Show the evidence. Give each supporting idea enough space to be read.Make the next step clear. Keep the action specific and easy to remember.

All sample text fits within its content boxes.

Text

Two columns

Place two bodies of content beside each other. Use it for paired explanations or an argument with supporting evidence. Pictures remain visible in full unless an explicit fit overrides the layout default.

Comparison

Compare alternatives using parallel information. Keep the same criteria and level of detail for every option.
