To begin with, identify the most important information and calls to action. Ensure such content is easily accessible and prominently displayed, especially on smaller screens. Use content hierarchy with headings, subheadings, and neatly segmented sections and paragraphs to ensure readers can scan the content. Use appropriate font sizes and highlight important information. Ensure there is enough white space for readability and visual appeal.
Consider responsive design techniques like collapsible menus, accordions, drop-down menus, and hidden content sections to optimize the layout and spacing.
Also, optimize media elements, including images and videos, for different screen sizes. You can use responsive design techniques to scale media elements proportionally or hide/display them based on the screen size.
