Mobile-First Design

1. Introduction

2. Key Concepts

1. Responsive Design: The ability for a website to adapt to various screen sizes and orientations.
2. Progressive Enhancement: Starting with a basic experience for mobile and adding features for larger screens.
3. Viewport: The user’s visible area of a web page, which is essential for mobile design.

3. Design Process

1. Define User Needs: Identify what users on mobile devices require.
2. Create Wireframes: Develop low-fidelity wireframes focusing on key interactions.
3. Design Visuals: Create high-fidelity designs considering mobile constraints.
4. Develop and Test: Build the site and conduct user testing across devices.

4. Best Practices

• Utilize a mobile-first CSS framework (e.g., Bootstrap, Foundation).
• Optimize images and resources for faster loading.
• Use relative units (e.g., ems, percentages) for scalable elements.
• Minimize use of large JavaScript libraries that can affect performance.
