Creating a responsive design with CSS involves using techniques that allow your web page to adapt to different screen sizes and devices. This is essential for ensuring that content is accessible and visually appealing across various platforms such as desktops, tablets, and smartphones.

Employing flexible grid layouts is a core principle of responsive design. This approach utilizes a system of columns that can adjust in size depending on the viewport. Media queries are also crucial as they allow you to apply different styles based on conditions such as screen width, orientation, and resolution. This means that you can tailor the presentation of your content for optimal viewing on any device. Additionally, using relative units like percentages or ems instead of fixed dimensions in pixels contributes significantly to flexibility, as these units allow elements to resize and reflow based on the size of their parent container or the viewport itself.

Therefore, the combination of flexible grid layouts, media queries, and relative units is the correct method for creating a responsive design with CSS, enabling a better user experience regardless of how or where the content is being viewed.
