Flexbox Container

In Flexbox, the container and its items are two main concepts. The container acts as a parent element, and the items are its child elements. The container establishes a new flex formatting context for its contents, which means that its child elements will be laid out using Flexbox instead of block or other formatting contexts.

The Flexbox formatting context has several properties, such as flex-direction, justify-content, align-items, align-content, …, that determine how the child elements will be positioned within the container. For example, flex-direction property can be set to row or column, which determines the direction in which the child elements are laid out.

The container creates a containing block for its contents, which means that the container acts as a parent element and its margins do not collapse with the margins of its contents. Additionally, the container provides a way to control the layout of its child elements, making it a powerful tool for creating flexible and responsive layouts.
