HTML stands for Hyper Text Markup Language. It is used to design web pages with the use of markup language. Hypertext defines the link between the web pages. HTML5 was released with the primary objective of improving the World Wide Web experience for developers and end-users. A markup language is used to define the text document inside the tag which defines the structure of web pages. HTML5 supports SVG (Scalable Vector Graphics), canvas, and other virtual vector graphics, which in HTML, using vector graphics was only possible by using it in connective with different technologies like Flash, VML (Vector Markup Language), or Silverlight.
With HTML5, JavaScript can run inside a web browser, while the older HTML only allows JavaScript to run in the browser interface thread. Web SQL databases are used in HTML5 for storing data temporarily. Meanwhile, in the previous version of HTML, only browser cache could be utilized for this purpose. HTML5 is not based on SGML. This means that the language has improved parsing rules which provide enhanced compatibility. You can use inline MathML and SVG in text with HTML5, whereas HTML restricts it.
What is HTML?
HTML stands for Hypertext Markup Language. HTML is the standard markup language for documents designed to be displayed in a web browser. HTML is not a programming language, it is a markup language that defines the structure of your website or can be say made of tags
HTML uses various tags, including headings, tables, and paragraphs, to define the text structures of a page. Each tag is defined using the and formula. It is usually called an “opening” and “closing” tag, respectively. For example, if you wish to change a specific text style to bold, you can use <b> type your text here</b> Your browser will render the content via these tags, then display it on the screen.
<!DOCTYPE html><html><head><title>The Basic HTML Structure</title><meta name="description" content=""/><meta name="keywords" content=""/><meta name="robots" content="index, follow" /><link rel="stylesheet" type="text/css" href="PUT_YOUR_CSS_FILE_NAME_HERE" ></head><body><h1>The Largest Heading</h1><p>This is paragraph</p><b>This is bold text</b><i>This is italic text</i><u>This is underline text</u></body></html>
The Output of Above HTML Code
Description
- <!DOCTYPE html> Tag used to tell the browser about HTML Version.
- <html> Tag used to define the root of HTML document.
Note: We should always define the attribute of <html> tag for language like <html lang="en">(en means english). - <title> Tag content show in browsers tab.
- <meta> Tags are used for search engine's crawler to tell the information about the webpage.
- <link> Tags are used to linking any external file to the current HTML document.
- <body> Tag is used to defining the body of document which content shows in the browser.
- <h1> is the largest heading.
- <p> Tag is used to define the paragraph.
- <b> Tag is to represent the bold content in the document.
- <i> Tag is to represent the italic content in the document.
- <u> Tag is to represent the underline content in the document.
Every HTML file start from <!DOCTYPE html> which is declared at the top of document so <!DOCTYPE html> tells the browser about the HTML version. After that we write <html> tag and then <head> tag, inside <head> tag we writes all the meta tags(for search engines crawler) as well as links of external css, js or other files. So mainly there are 3 type of html elements/tags i.e. opening tags, closing tags and self-closing tags.
Here are some valid list of self-closing tags
<br /><hr /><area /><col /><base /><meta /><embed /><param /><img /><source /><track /><wbr /><input /><link />
