01 What It Does

Define a Responsive Page Grid

A concise reference for grid anatomy, grid types, responsive behavior, and common page-layout patterns.

Source-based workflowNot an execution benchmark

The Working Approach

Layout Grid focuses on the page skeleton: columns, gutters, outside margins, and how they change across viewport sizes. It distinguishes fluid columns from fixed maximum-width containers and adaptive layouts, so a grid specification can describe behavior as well as a desktop screenshot.

The source is a compact guide, not an implementation library. Its common column counts and breakpoint examples are starting points. The useful output is a grid chosen for the content, with clear instructions for full-bleed areas, contained reading sections, sidebars, and repeated cards.

Expected Deliverables

  • A breakpoint table with columns, gutters, margins, and container limits.
  • Layout rules for contained, full-bleed, sidebar, and card regions.
  • Developer-facing notes explaining adaptation between widths.

From Brief to Review

  1. 01
    Choose the Grid Type

    Match column, modular, baseline, or compound structure to the content instead of assuming every page needs the same grid.

  2. 02
    Specify Width Behavior

    Define where columns stretch, where a container stops growing, and when columns or sidebars drop.

  3. 03
    Review Intermediate Widths

    Check the transitions around breakpoints, not only the smallest and largest reference screens.

02 When to Use It

When to Use It

No named runtime dependency; requires real content constraints to select useful grid values.

A Good Fit

  • Establishing Page StructureUseful before producing a family of screens that should share alignment.
  • Reconciling Layout PatternsProvides a common basis for pages mixing prose, cards, and asymmetric regions.

Limits to Check

  • Not Internal Spacing TokensPadding and gaps within components are the focus of Spacing System.
  • Test the BreakpointsSuggested values need testing with real content and the target environment.

Bring These Inputs

  • Content RegionsList the major page areas and their relative importance.
  • Viewport TargetsProvide supported widths and any existing container conventions.
  • Layout ConstraintsIdentify fixed sidebars, minimum card widths, and intentional full-bleed sections.

03 Decisions That Matter

Decisions That Matter

  1. Behavior Is Part of the Grid

    A specification that only describes desktop columns leaves the most difficult responsive decisions unresolved.

  2. Intentional Exceptions

    Grid-breaking can emphasize content, but should be deliberate rather than an accidental misalignment.

No named runtime dependency; requires real content constraints to select useful grid values.

Start With One Deliverable

Adapt the scope, source material and constraints in this brief before running the skill.

Example Brief
Use layout-grid to specify a documentation page with a section sidebar, article body, and optional table of contents. Define column counts, gutters, margins, maximum widths, and collapse behavior. Explain what happens between desktop and mobile and keep reading width separate from the outer page grid.

Inspect the Result

Check the actual output against these observable criteria.

  • Each target width has explicit margin and gutter rules.
  • Sidebar collapse is described rather than implied.
  • Intentional grid exceptions are named.

06 Questions Before You Start

Questions Before You Start

Does it require a 12-column desktop grid?

No. The source lists common column counts and several grid types; the content should determine the selection.

Will it output CSS?

The source asks for documented grid specifications but does not mandate a specific CSS framework or code deliverable.

How is it different from responsive design?

This Skill concentrates on the structural grid. Broader responsive decisions include content priority, controls, and cross-device interaction.
