Responsive CSS Grid Layouts for Documentation

Multi-Column Technical Reading Layouts

A modern documentation reader pairs a sticky left syllabus rail (280px), a flexible central reading column (minmax(0, 1fr)), and a sticky right table of contents (240px) on desktop screens, collapsing gracefully to a single column with a slide-over drawer on mobile devices.

breakpoints = {
    "mobile": "<= 768px (1 column + drawer)",
    "tablet": "769px - 1023px (2 columns: syllabus + content)",
    "desktop": ">= 1024px (3 columns: syllabus + content + TOC)"
}
for device, layout in breakpoints.items():
    print(f"{device.capitalize():8s}: {layout}")
