Introduction
In the previous article, we explored basic layout components like padding, margin, and spacing. Now, let's take a leap to a more advanced component: FlexLayout. With it, we can create flexible layouts adaptable to any screen, thanks to the power of CSS Flexbox.
FlexLayout: The Flexible Container
FlexLayout is a container that allows us to organize components flexibly, controlling their alignment, size, and order.
It inherits from the FlexComponent interface, just like horizontal and vertical layouts, which means we can use the same properties to customize its behavior.
Key features:
- Flexibility in organizing components.
- Control of alignment, size, and order.
- Inheritance from the FlexComponent interface.
Essential FlexLayout Properties
-
Flex Direction: Defines the main direction of the layout, which can be row, reverse-row, column, or reverse-column.
-
Justify Content: Aligns components on the main axis, controlling the distribution of free space.
-
Align Items: Aligns components on the cross axis.
-
Align Self: Aligns an individual component on the cross axis.
-
Relative Size, Flex Shrink, and Flex Grow
-
Relative Size: Allows you to define the size of a component relative to its parent container.
-
Flex Shrink: Controls the ability of a component to shrink to fit into the container.
-
Flex Grow: Controls the ability of a component to grow to occupy the free space in the container.
- Wrapping and Content Alignment
-
Wrapping: Allows components to break to new lines when there is not enough space in the container.
-
Align Content: Aligns the lines of components on the cross axis, controlling the distribution of free space between the lines.
