How to Use Semantic HTML Tags Effectively
To use semantic HTML tags effectively, you need to understand the different types of tags and how to use them correctly. The following are some tips:
- Use the right tag for the right content. For example, use the
<h1>tag for the main heading of your page and the<h2>tag for subheadings. - Use nested tags to create a hierarchy for your content. For example, you could nest a
<h2>tag within a<h1>tag to create a subheading within the main heading. - Use descriptive tag attributes. For example, you could use the
altattribute to describe an image.

Implementation of the HTML semantic tags
This HTML document uses all of the major semantic tags in a way that is both meaningful and accessible. The <header> tag contains the website's title and navigation menu, the <main> tag contains the main content of the page, the <aside> tag contains the sidebar content and the <footer> tag contains the footer content.
The <section> tag is used to divide the main content into different sections, and the <details> tag is used to hide additional content by default. The <h1> to <h6>Tags are used to create headings of different levels, with <h1> the most important heading and <h6> being the least important heading.
