What are semantic HTML tags? Can you give some examples?

Semantic HTML tags are those that offer meaning to the content within them, making it more understandable for both search engines and users, thereby improving accessibility. Examples of semantic tags include:

1. <header> Represents the header section of a page, often containing navigation or introductory content.
2. <article> Defines a standalone section of content that could be distributed independently.
3. <footer> Denotes the footer of a page, typically containing copyright and legal information.
4. <section> Groups related content together within a page for better organization.
5. <aside> Marks content that is tangential to the main content, like sidebars.
