Flexbox Layout
Flexbox is the modern way to create layouts in CSS. It makes it easy to align and distribute space.
.container {
display: flex;
justify-content: space-between; /* horizontal */
align-items: center; /* vertical */
gap: 20px; /* space between items */
flex-wrap: wrap; /* wrap to next line */
}
.item {
flex: 1; /* grow to fill space equally */
}Common Values
| Property | Values |
|---|---|
| justify-content | flex-start, center, space-between, space-around, space-evenly |
| align-items | flex-start, center, flex-end, stretch |
| flex-direction | row (default), column, row-reverse, column-reverse |
