A Complete Small Guide to Semantic HTML
Semantic HTML is the use of HTML tags that provide meaning to the content of web pages. This guide will walk you through the basics and importance of using semantic HTML elements, updated for 2024.
What is Semantic HTML?
Semantic HTML introduces meaning to the web content, making it more understandable for browsers, search engines, and developers. Unlike non-semantic tags (<div>, <span>), semantic tags clearly describe their purpose and content.
Key Benefits of Semantic HTML
- Improved Accessibility: Semantic HTML enhances the accessibility of web content for screen readers and other assistive technologies.
- Better SEO: Search engines use semantic tags to understand the structure and context of the content, improving SEO.
- Easier Maintenance: Semantic HTML provides a clear structure, making the code easier to read, understand, and maintain.
- Enhanced User Experience: Semantic tags can improve the overall user experience by providing a logical structure to the content.
