Text headings play a crucial role in structuring content and improving readability. By providing a visual hierarchy, headings help readers scan and understand the relationship between different sections of text. Effective headings are clear, concise, and informative, giving readers a preview of the content that follows. They not only guide the reader through the text but also enhance the overall user experience. When used appropriately, text headings can make a significant difference in organizing information and creating a more user-friendly and accessible writing piece.
