Frequently Asked Questions

How do I make my design responsive?

Use media queries to create responsive designs. Start with mobile-first approach and add breakpoints as needed. Example:

@media (min-width: 768px) {
    /* Tablet styles */
}
@media (min-width: 1024px) {
    /* Desktop styles */
}

What's the difference between Flexbox and Grid?

Flexbox is one-dimensional and perfect for laying out items in a row or column. Grid is two-dimensional and ideal for complex layouts with rows and columns. Use Flexbox for component-level layouts and Grid for page-level layouts.

How do I center elements vertically and horizontally?

The easiest way is using Flexbox:

.container {
    display: flex;
    justify-content: center;
    align-items: center;
    min-height: 100vh;
}
