Text emphasis refers to techniques used to highlight or stress certain words or phrases within a written text. This can be achieved through various methods, such as using bold or italic formatting, changing font size, or applying color. The goal is to draw the reader's attention to specific information, making it stand out and easier to remember. Common applications of text emphasis include headings, subheadings, and keywords in articles, presentations, and educational materials. By effectively using emphasis, writers can enhance clarity and improve the overall readability of their content, guiding readers to the most important points.
