What happens if you set display: flex on the tag?

Setting `display: flex` on the ` ` tag turns the entire body into a flex container, allowing its immediate children to be laid out according to Flexbox rules. All direct child elements of ` ` become flex items and can be aligned, spaced, and ordered using Flexbox properties. You can use `justify-content`, `align-items`, and `flex-direction` to control the placement of all main page content. The body itself behaves like a block element by default, but flex container rules will control its children. Height issues may arise: if you want vertical centering or full-page layouts, you may need `height: 100vh` on ` ` to ensure the flex container fills the viewport. Header Main Content Footer In this example, the ` `, ` `, and ` ` elements become flex items. They are vertically centered in the viewport because the body uses `justify-content: center` and `align-items: center`. Use `display: flex` on ` ` when you want to control overall page layout using Flexbox. Set the body height explicitly (like `100vh`) to enable vertical alignment. Combine with `min-height` or `flex-grow` on child elements for responsive full-page layouts. Be careful with global flex rules—they affect all direct children, so apply additional wrappers if needed for complex layouts.
