What is a key difference between tables and CSS for layout control?

A key difference between tables and CSS for layout control is that CSS offers more flexibility for responsive designs. CSS allows designers to create layouts that can adapt to various screen sizes and orientations, which is essential in today's multi-device environment. With CSS techniques such as media queries, grid systems, and flexbox, developers can control how content is displayed across different devices, ensuring a consistent user experience.

In contrast, tables were historically used for layout purposes, but they do not provide the same level of responsiveness. Tables are not inherently designed for managing layout in the way CSS does, making them less efficient for adaptable designs. Using tables for layout can lead to fixed-width designs that may not look good on smaller screens or mobile devices.

In summary, the capability of CSS to provide responsive design features makes it a significant advancement over tables when it comes to modern web development and layout control.
