Flexbox (Flexible Box Layout) is a powerful CSS layout module that allows elements to be aligned and distributed efficiently inside a container, even when their sizes are unknown or dynamic. It is especially useful for responsive design.
Basic Flexbox Structure
To enable Flexbox, set display: flex; on a container.
.container {
display: flex;
}
Main Flexbox Properties
1. Flex Container Properties
These properties apply to the parent (flex container).
Example:
.container {
display: flex;
flex-direction: row;
justify-content: space-between;
align-items: center;
}
2. Flex Item Properties
These properties apply to individual flex items inside a container.
Example:
.item {
flex-grow: 1;
flex-basis: 200px;
align-self: flex-start;
}
Flexbox Example
<div class=”container”>
<div class=”item”>Item 1</div>
<div class=”item”>Item 2</div>
<div class=”item”>Item 3</div>
</div>
.container {
display: flex;
justify-content: space-around;
align-items: center;
}
.item {
width: 100px;
height: 50px;
background: lightblue;
}
