flex-direction
Flex-direction is a CSS property that defines the direction of the main axis of a flex container. The main axis is the primary axis that items are laid out along in a flex container, and it can be either horizontal (row) or vertical (column). The flex-direction property can be set to one of four values:
- row: items are laid out horizontally in a single row
- row-reverse: items are laid out horizontally in a single row, but in reverse order
- column: items are laid out vertically in a single column
- column-reverse: items are laid out vertically in a single column, but in reverse order
By default, the value of flex-direction is row, which means that items are laid out horizontally in a single row. However, this property can be used to change the layout of items in a flex container to suit the design of a webpage or application.
flex-direction: column;
The `flex-direction: column;` is a CSS property that changes the direction of the flex container's main axis to be vertical. This means that the flex items will be stacked on top of each other within the container, rather than side by side.
Here’s an example of how to use it:
```
.container {
display: flex;
flex-direction: column;
}
```
In this example, the `flex-direction: column;` property is applied to the `.container` class, which is a flex container. This will cause the child elements of the container to be arranged vertically, from top to bottom.
Other possible values for `flex-direction` include `row`, `row-reverse`, and `column-reverse`. These values change the direction of the flex container's main axis to be horizontal, in reverse order, or vertical in reverse order, respectively.
