Why is semantics necessary in web development?

Semantic in web development is the use of HTML elements according to their meaningful purpose. This is important for:

• Accessibility: Semantic markup helps assistive technologies (like screen readers) interpret the page content correctly.
• SEO: Search engines better understand the structure and content of the site, improving ranking.
• Ease of maintenance and development: The code becomes clearer for developers.
• User experience: Semantic tags help browsers and devices display and process content correctly.

For example, using <header>, <nav>, <article>, <footer> instead of generic <div> makes the page structure more understandable and logical.
