Day 5: Flexbox

Goal

Learn how to create modern, responsive layouts easily using CSS Flexbox.

Topics

display: flex – enables flex container
Flex direction: row, column
Justify content: flex-start, center, space-between, etc.
Align items: flex-start, center, stretch
Flex wrap & gap between items

Flexbox Example

.container {
  display: flex;
  flex-direction: row;       /* row or column */
  justify-content: space-between; /* horizontal alignment */
  align-items: center;       /* vertical alignment */
  gap: 10px;                 /* space between items */
}

Practice

Create a navigation bar using Flexbox.
Align 3 boxes evenly with space between them.
