The misuse of HTML semantic tags, particularly <em> and <i>, has led to confusion and accessibility issues, especially with the evolution of HTML standards from 2.0 to 5. While the <em> tag is often used for emphasis, HTML5 clarifies it as being for stress emphasis, meaning it highlights a word that alters the meaning of a sentence, whereas <i> is used for text that is italicized for other reasons, such as foreign phrases or technical terms. The article highlights the importance of using these tags correctly to improve accessibility for screen readers and suggests that modern tools and editors often misapply these tags, defaulting to <em> for italics and <strong> for bold without considering the semantic intent. This misapplication can complicate the reading experience for users relying on assistive technologies. The article advocates for thoughtful use of text-level semantics to enhance web communication and accessibility, emphasizing the need for developers to understand the purpose behind styling choices and the impact on user experience.
