How Can I Make Flexbox Children Fill Their Parent's Height?

Filling Flexbox Children to Parent Height with align-items: stretch

In Flexbox, achieving 100% height for children within their parent container poses a challenge. One approach is to set the parent's height to 100%, which behaves as expected in most browsers. However, when using fixed heights, this method fails.

To overcome this, the solution lies in utilizing align-items: stretch. This property ensures that child elements occupy the entire available vertical space within the parent Flexbox. However, it's crucial to remove height: 100% from the child component to allow the align-items: stretch property to take effect.

Alternatively, align-self: stretch can be applied specifically to the child element that requires stretching, while keeping flex-direction: column for the parent container. This approach provides more control over the vertical spacing of specific children.
