Flexbox Basics: Key Properties
Before jumping into tutorials, it’s essential to understand the core Flexbox properties.
flex-direction
The flex-direction property defines the main axis of your flex container. You can arrange items row, row-reverse, column, or column-reverse.
.container {
display: flex;
flex-direction: row;
}

justify-content
This property aligns items along the main axis. Options include flex-start, flex-end, center, space-between, and space-around.
.container {
justify-content: space-between;
}
Perfect for evenly spaced JavaScript UI elements.
align-items
The align-items property aligns items along the cross axis. Use flex-start, flex-end, center, baseline, or stretch.
.container {
align-items: center;
}
Great for aligning content in mobile design layouts.
flex-wrap
By default, Flexbox items try to fit in a single line. flex-wrap allows items to move to a new line when necessary.
.container {
flex-wrap: wrap;
}
Useful for responsive design grids.

justify-content: space-around;
background-color: #333;

.navbar a {
color: white;
text-decoration: none;
