Flexbox Demo

1. Row direction

Items sit next to each other from left to right.

.row-demo {
  display: flex;
  flex-direction: row;
}

2. Column direction

Items stack from top to bottom.

.column-demo {
  display: flex;
  flex-direction: column;
}

3. justify-content

This controls distribution along the main axis.

.justify-demo {
  display: flex;
  justify-content: space-between;
}

4. align-items

This controls alignment on the cross axis.

.align-demo {
  display: flex;
  align-items: center;
}

5. gap

Gap adds space between items without using margins on the children.

.gap-demo {
  display: flex;
  gap: 24px;
}

6. flex-wrap

Items can move onto a new line when there is not enough room.

.wrap-demo {
  display: flex;
  flex-wrap: wrap;
  gap: 12px;
}

7. flex-grow

One item can expand and take the remaining available space.

.grow-demo {
  display: flex;
  gap: 12px;
}

.grow-item {
  flex-grow: 1;
}

8. Figma-like header

This behaves like a horizontal Auto Layout frame in Figma.

.ui-header {
  display: flex;
  justify-content: space-between;
  align-items: center;
  gap: 24px;
}

9. Responsive flex layout

This row becomes a column on smaller screens.

.responsive-flex-demo {
  display: flex;
  gap: 16px;
}

.responsive-item {
  flex: 1;
}

@media (max-width: 700px) {
  .responsive-flex-demo {
    flex-direction: column;
  }
}
