Common Deprecated HTML Tags:

  1. <font>: The <font> tag was used to change the font size, color, and face within text. This tag has been deprecated in favor of using CSS (Cascading Style Sheets) to control text styles.
  2. Alternative: Use CSS styles to control font properties, such as font-size, font-family, and color.
  3. <center>: The <center> tag was used to center-align text and other content within an element. It has been deprecated in favor of using CSS for text alignment.
  4. Alternative: Use CSS properties like text-align: center; to center-align content.
  5. <strike>: The <strike> tag was used to strike through text, typically indicating deleted or outdated content. This tag has been deprecated in favor of using the more semantically meaningful <del> tag and CSS for styling.
  6. Alternative: Use the <del> tag for deleted content and style it with CSS if necessary.
  7. <frame>: The <frame> tag was once used to define individual frames within a frameset for creating complex layouts. Framesets themselves have been deprecated, and modern web development relies on more flexible and responsive layout techniques, such as CSS Grid and Flexbox.
  8. Alternative: Use modern CSS layout techniques to create responsive web layouts.
  9. <marquee>: The <marquee> tag was used to create scrolling or moving text or images. It has been deprecated due to its distracting and non-accessible nature.
  10. Alternative: Use CSS animations or JavaScript for scrolling or moving content in a more user-friendly and accessible manner
