Mobile-First Design Principles

Mobile-First Design Principles

Design your blog with mobile users in mind first, then enhance for larger screens.

Mobile-First Approach

Start with mobile design and scale up:

/* Mobile styles (default) */
.container {
    padding: 1rem;
    max-width: 100%;
}

/* Tablet styles */
@media (min-width: 768px) {
    .container {
        padding: 2rem;
        max-width: 750px;
    }
}

/* Desktop styles */
@media (min-width: 1024px) {
    .container {
        padding: 3rem;
        max-width: 1200px;
    }
}

Touch-Friendly Interfaces

Design for touch interaction:

• Minimum 44px touch targets
• Adequate spacing between elements
• Clear visual feedback
• Simple navigation patterns

Responsive Images

Optimize images for different screen sizes:

<img src="image-small.jpg" 
     srcset="image-small.jpg 300w,
             image-medium.jpg 600w,
             image-large.jpg 900w"
     sizes="(max-width: 768px) 100vw,
            (max-width: 1024px) 50vw,
            33vw"
     alt="Description">
