Flexbox in CSS: A Flexible Layout Solution

In modern web design, organizing and aligning elements on a page is crucial. One of the powerful tools that helps achieve this is Flexbox (Flexible Box Layout). Flexbox allows you to create flexible and easily adjustable layouts, providing an optimal user experience.

Flex Container and Flex Items

When using Flexbox, you'll work with two main concepts:

• Flex Container: The parent element defined by the property display: flex;. All child elements inside it become Flex Items.
