Here we will explore each property value with their examples:
1. Normal Value
The normal value behaves as the default alignment in the flex container. It generally acts like stretch in most cases, making items fill the container's cross-axis, but it can also behave differently depending on the flex context or item-specific properties.
Syntax:
align-items: normal;Example: In this example, we are demonstrating the align-items: normal property in a flex container. The normal div has two child divs with blue and red backgrounds, and by default, they align according to the container's natural flow, stretching to fit the available space as needed.
