HTML stands for Hyper Text Markup Language. With HTML, you can create your own Website. It describes the structure of Web pages using markup.
There are three types of lists - Unordered, Ordered and Definition. Unordered lists contain bullet points. They are used when the order of elements in the list is not important. Ordered lists have some kind of numeric counter preceding each list item, and definition lists contain terms and their definitions.
Most documents have headings in one form or another. In longer pieces of text, headings can also help structure a document. HTML offers six levels of headings, which use the elements - <h1>, <h2>, <h3>, <h4>, <h5>, and <h6>. Browsers display the <h1> element as the largest of the six and <h6> as the smallest.
Document Type Declaration (Doctype)
Web browsers can display several types of documents, not just HTML. So. when creating a web document, the first thing is tell the browser what type of document is coming. You declare the type of document with a special line of HTML at the top of the document.
