The display CSS property determines how an element is rendered and displayed on the webpage. It controls the box type and behavior of an element, affecting its layout and visibility. The display property can take various values, including block, inline, inline-block, flex, grid, and more.
For example, display: none; will hide the element completely, while display: flex; will render the element as a flexible box container. The display property is a fundamental tool for controlling the layout and structure of web pages.
