HOW DOES HTML WORK? HTML documents are files that end with a. html or. htm extension. You can view then using any web browser (such as Google Chrome, Safari, or Mozilla Firefox). The browser reads the HTML file and renders its content so that internet users can view it.
BASIC HTML DOCUMENT In its simplest form, following is an example of an HTML document − <!DOCTYPE html> <head> <title>This is document title</title> </head> <body> <h 1>This is a heading</h 1> <p>Document content goes here. . . </p> </body> </html>
DIFFERENCE BETWEEN HTML AND HTML 5 HTML 4 1. HTML 5 uses new structures such as drag, drop and much more. 2. HTML 5 can contain embedded video and audio without using flash player. 3. HTML 5 is capable of handling inaccurate syntax HTML 5 1. HTML 4 uses common structures like headers , footers. 2. HTML 4 cannot embed video or audio directly and makes use of flash player for it. 3. HTML 4 cannot handle inaccurate syntax
DIFFERENCE HTML 4 4. HTML 5 introduced many new API’s which facilitate flexibility of web pages. 5. In HTML 5, new tags and new features like local storage are enhanced. HTML 5 4. HTML 4 has traditional API’s which does not include canvas and content editable API’s. 5. In HTML 4, local storage is not possible and tags that can handle only one dimension are present
THE MOST USED HTML TAGS HTML tags have two main types: block-level and inline tags. Block-level elements take up the full available space and always start a new line in the document. Headings and paragraphs are a great example of block tags. Inline elements only take up as much space as they need and don’t start a new line on the page. They usually serve to format the inner contents of block-level elements. Links and emphasized strings are good examples of inline tags.
BLOCK-LEVEL TAGS The three block level tags every HTML document needs to contain are <html>, <head>, and <body>. The <html></html> tag is the highest level element that encloses every HTML page. The <head></head> tag holds meta information such as the page’s title and charset. Finally, the <body></body> tag encloses all the content that appears on the page.
INLINE TAGS Many inline tags are used to format text. For example, a <strong></strong> tag would render an element in bold, whereas <em></em> tags would show it in italics. Hyperlinks are also inline elements that require <a></a> tags and href attributes to indicate the link’s destination: <a href="https: //example. com/">Click me!</a> Images are inline elements too. You can add one using <img> without any closing tag. But you will also need to use the src attribute to specify the image path, for example: <img src="/images/example. jpg" alt="Example image">
PROS OF HTML • A widely used language with a lot of resources and a huge community behind. • Runs natively in every web browser. • Comes with a flat learning curve. • Open-source and completely free. • Clean and consistent markup. • The official web standards are maintained by the World Wide Web Consortium (W 3 C). • Easily integrable with backend languages such as PHP and Node. js.
CONS OF HTML Mostly used for static web pages. For dynamic functionality, you may need to use Java. Script or a backend language such as PHP. It does not allow the user to implement logic. As a result, all web pages need to be created separately, even if they use the same elements, e. g. headers and footers. Some browsers adopt new features slowly. Browser behavior is sometimes hard to predict (e. g. older browsers don’t always render newer tags).
