1. What is HTML and why is it important?
Answer: HTML (HyperText Markup Language) is the standard language used to create and design documents on the World Wide Web. It structures web content and allows the inclusion of text, images, links, and other elements. HTML is crucial because it forms the backbone of all web content, allowing browsers to display text, images, and multimedia in a structured manner.(h2kinfosys.com)(https://www.h2kinfosys.com/blog/top-html-css-javascript-interview-questions-answers/?utm_source=chatgpt.com))
Answer: HTML tags are the building blocks of HTML. They are used to create elements and structure content on a web page. Tags are enclosed in angle brackets, e.g.,<p>for a paragraph. Most tags come in pairs: an opening tag<p>and a closing tag</P> . Attributes provide additional information about HTML elements. They are included within the opening tag and usually come in name-value pairs, like name=”value”. For example, in <a href=”https://www.example.com“>Link</a>,href is an attribute specifying the URL of the link.(geeksforgeeks.org) (https://www.geeksforgeeks.org/html/html-interview-questions/?utm_source=chatgpt.com))
