Both <strong> and <b> tags make text appear bold, but they serve different purposes. The <b> tag is purely visual, while the <strong> tag adds semantic meaning, indicating that the text is important. Screen readers emphasize <strong> text but not <b> text.
<b>: makes text bold without adding importance (visual styling only).
<strong>: makes text bold and conveys importance or emphasis.
Screen readers give <strong> special vocal stress, improving accessibility.
For semantic HTML, prefer <strong> over <b> when the text is important.
