<p>HTML (Ngôn ngữ đánh dấu siêu văn bản), là một ngôn ngữ mang tính miêu tả chỉ dành riêng cho cấu trúc trang web.</p>
<h2 id="LƯỢC_SỬ">LƯỢC SỬ </h2>
<p>Vào năm 1990, như một phần của công trình thiết kế web {{glossary("World Wide Web","Web")}}, Tim Berners-Lee tạo ra định nghĩa {{glossary("hypertext")}}, thứ mà đã được Berners-Lee chính thức công nhận vào năm tiếp theo thông qua markup được dựa phần lớn vào{{glossary("SGML")}}. The {{glossary("IETF")}} began formally specifying HTML in 1993, and after several drafts released version 2.0 in 1995. In 1994 Berners-Lee founded the {{glossary("W3C")}} to develop the Web. In 1996, the W3C took over the HTML work and published the HTML 3.2 recommendation a year later. HTML 4.0 was released in 1999 and became an {{glossary("ISO")}} standard in 2000.</p>
<p>At that time, the W3C nearly abandoned HTML in favor of {{glossary("XHTML")}}, prompting the founding of an independent group called {{glossary("WHATWG")}} in 2004. Thanks to WHATWG, work on {{glossary("HTML5")}} continued: the two organizations released the first draft in 2008 and the final standard in 2014.</p>
<h2 id="Concept_and_syntax">Concept and syntax</h2>
<p>An HTML document is a plaintext document structured with {{glossary("element","elements")}}. Elements are surrounded by matching opening and closing {{Glossary("tag","tags")}}. Each tag begins and ends with angle brackets (<code><></code>). There are a few empty or <em>void</em> tags that cannot enclose any text, for instance {{htmlelement("img")}}.</p>
<p>You can extend HTML tags with {{Glossary("attribute","attributes")}}, which provide additional information affecting how the browser interprets the element:</p>
<p><img alt="Detail of the structure of an HTML element" src="https://mdn.mozillademos.org/files/7659/anatomy-of-an-html-element.png" style="height: 181px; width: 609px;"></p>
<p>An HTML file is normally saved with an <code>.htm</code> or <code>.html</code> extension, served by a {{Glossary("Server","web server")}}, and can be rendered by any {{Glossary("Browser","Web browser")}}.</p>
