# Responsive Layout Example

Mobile-first design with CSS Grid, Flexbox, and media queries

## Mobile First

Start with mobile styles as the base, then progressively enhance for larger screens using media queries.

## CSS Grid

Powerful 2D layout system that adapts from 1 column on mobile to 4 columns on large desktops.

## Flexbox

Perfect for 1D layouts like navigation bars and content alignment within components.

## Media Queries

Breakpoints at 768px (tablet), 1024px (desktop), and 1440px (large desktop) for optimal viewing.

## CSS Variables

Custom properties for consistent spacing, colors, and typography throughout the design.

## Accessibility

Support for reduced motion, high contrast, and dark mode preferences using media queries.

## Main Content Area

This layout demonstrates a responsive sidebar pattern. On mobile devices, the sidebar appears below the main content. On tablets and larger screens, it moves to the side using Flexbox.

The layout automatically adjusts based on screen size, ensuring optimal readability and usability across all devices.
