Understanding CSS Flexbox
CSS Flexbox (Flexible Box Layout) is a one-dimensional layout method that allows you to arrange items in a row or column with powerful alignment and distribution capabilities.
Flexbox Terminology
- Flex Container: The parent element with
display: flex
- Flex Items: Direct children of the flex container
- Main Axis: The primary axis along which flex items are laid out
- Cross Axis: The axis perpendicular to the main axis
- Main Start/End: The start and end points of the main axis
- Cross Start/End: The start and end points of the cross axis
Your First Flexbox

<div class="flex-item">1</div>
<div class="flex-item">2</div>
<div class="flex-item">3</div>
</div>
/* CSS */
.flex-container {
display: flex; /* Creates a flex container */
gap: 10px; /* Space between flex items */
}
.flex-item {
background-color: #ff6b6b;

justify-content: flex-end; /* Items at end */
justify-content: center; /* Items centered */
justify-content: space-between; /* Equal space between items */

height: 200px; /* Need height to see cross-axis alignment */
align-items: stretch; /* Default: items stretch to fill */
align-items: flex-start; /* Items at cross-axis start */
align-items: flex-end; /* Items at cross-axis end */
align-items: center; /* Items centered on cross-axis */
align-items: baseline; /* Items aligned by text baseline */
}
/* Perfect centering */

justify-content: center; /* Horizontal centering */
align-items: center; /* Vertical centering */
height: 100vh; /* Full viewport height */
}

}
/* Shorthand syntax */
.flex-item {
flex: 1; /* flex: 1 1 0% (grow shrink basis) */
flex: 0 1 auto; /* Default values */
flex: none; /* flex: 0 0 auto (inflexible) */
flex: auto; /* flex: 1 1 auto (flexible) */
}
/* Common patterns */
.sidebar {
flex: 0 0 250px; /* Fixed width sidebar */
}
.main-content {
flex: 1; /* Takes remaining space */
}
.flexible-item {
flex: 1 1 200px; /* Grows/shrinks, min 200px */
}
.fixed-item {
flex: none; /* Doesn't grow or shrink */
width: 100px;
}
Fixed 100px
Flexible
2x Flexible
flex: 0 0 100px | flex: 1 | flex: 2
Align Self

align-self: flex-start; /* Align to cross-axis start */
align-self: flex-end; /* Align to cross-axis end */
align-self: center; /* Center on cross-axis */
align-self: baseline; /* Align to text baseline */
align-self: stretch; /* Stretch to fill container */
}
/* Example: Mixed alignment */
.mixed-alignment .item-1 { align-self: flex-start; }
.mixed-alignment .item-2 { align-self: center; }
.mixed-alignment .item-3 { align-self: flex-end; }

order: 0; /* Default order */
}
/* Change visual order without changing HTML */
.item-first {
order: -1; /* Appears first */
}
.item-last {
order: 1; /* Appears last */
}
/* Responsive reordering */
