Aspect ratio refers to the proportional relationship between the width and height of an element, such as an image or video. It plays a crucial role in maintaining visual harmony and preventing distortion. Understanding and implementing aspect ratio in HTML is essential for creating responsive and visually appealing web designs.
To maintain aspect ratio, you can use CSS techniques like setting a percentage-based width or height, using padding or margins, or employing the object-fit property. Additionally, HTML5 introduces the <picture> element, which allows specifying multiple sources with different aspect ratios, ensuring optimal display on various devices.
By incorporating aspect ratio techniques into your HTML code, you can ensure that your content looks great across different screen sizes and devices, providing an enhanced user experience.
