1. <acronym> Tag:
Purpose:
The <acronym> tag was used in earlier versions of HTML to define an acronym, allowing users to see the full form of the abbreviation by hovering over it with their cursor. This tag was particularly useful for improving accessibility and user understanding, as it provided additional context for shortened terms without cluttering the main content. When a user hovered over the acronym, the browser would display a small tooltip containing the expanded form, helping readers understand the meaning of technical or unfamiliar terms.
<acronym title=”World Health Organization”>WHO</acronym>
The <acronym> tag was replaced by the <abbr> tag, which serves the same purpose and is better supported in HTML5. <abbr> is more consistent and widely recognized by modern browsers and assistive technologies.
2. <center> Tag:
Purpose:
The <center> tag was historically used in HTML to center-align text, images, and other elements within a webpage. However, it has been deprecated in HTML5 and is no longer recommended for modern web development. Instead, developers now use CSS properties such as text-align: center; for inline and block elements or margin: auto; for centering block-level elements. Additionally, the display: flex; and justify-content: center; properties in CSS provide more flexible and responsive centering options for aligning content within containers.
<center>
<h2>Welcome to My Website</h2>
</center>- Separation of Content & Style: The
<center>tag applied visual styling, which should be handled by CSS rather than HTML. - Flexibility: CSS offers more powerful and flexible methods to center content.
3. <marquee> Tag:
Purpose:
The <marquee> tag was traditionally used in HTML to create scrolling text or moving content effects, allowing text or images to move horizontally or vertically across a webpage. This tag provided attributes such as direction, behavior, scrollamount, and loop to control the movement, speed, and repetition of the scrolling effect. However, the <marquee> tag is now obsolete and deprecated in modern HTML5 due to accessibility and usability concerns. Instead, developers are encouraged to use CSS animations or JavaScript to achieve similar scrolling effects in a more flexible and standards-compliant manner.
