HTML allows web developers to define the content and appearance of a webpage, including text, images, links, and multimedia elements. By using HTML tags such as

In addition to defining the structure of a webpage, HTML also plays a crucial role in search engine optimization (SEO) by providing metadata through tags like HTML's metadata tags help search engines understand the content of a webpage, making it easier for users to find relevant information. This can improve a website's visibility and ranking in search results. Additionally, HTML allows for the implementation of responsive design techniques, ensuring that websites adapt to various screen sizes and devices for a seamless user experience.

</p>). - HTML tags can have attributes that provide additional information about an element. Attributes are included within the opening tag and usually come in name/value pairs (e.g.,
<a href="https://www.example.com">Link</a>). - HTML tags can have attributes that provide additional information about an element. Attributes are included within the opening tag and usually come in name/value pairs (e.g.,
<a href="https://www.example.com">Link</a>).
