HTML Introduction
- 1. HTML • Language for describing web pages. • Hyper Text Markup Language • Its not a programming language, it is a markup language • A markup language is a set of markup tags
- 2. HTML Tags • HTML markup tags = HTML tags • Keywords surrounded by angle brackets like <html> • Normally come in pairs like <b> and </b> • The first tag in a pair is the start tag (opening tag) and the second tag is the end tag (closing tag)
- 3. HTML Pages • HTML Documents = Web Pages • HTML documents describe web pages • HTML documents contain HTML tags and plain text • HTML documents are also called web pages
- 4. Browser • The purpose of a web browser (like Internet Explorer or Firefox) is to read HTML documents and display them as web pages. • The browser does not display the HTML tags, but uses the tags to interpret the content of the page
- 5. Browser • <html> <body> <h1>My First Heading</h1> <p>My first paragraph</p> </body> </html>
- 6. HTML Editor • A simple text editor can be use to write html tags. • HTM or HTML extension can be use.
- 7. Heading Tags <h1> This is heading 1 </h1> <h2> This is heading 2 </h2> <h3> This is heading 3 </h3> <h4> This is heading 4 </h4> <h5> This is heading 5 </h5> <h6> This is heading 6 </h6>
- 8. Paragraph Tags <html> <body> <p>This is a paragraph.</p> <p>This is a paragraph.</p> <p>This is a paragraph.</p> </body> </html>
- 9. Anchor Tags <html> <body> <a href="http://www.jetskill.com"> This is a link</a> </body> </html> This is a link
- 10. Image Tags <html> <body> <img src=“jetskill.jpg" width="104" height="142" /> </body> </html>
- 11. Empty HTML Elements HTML elements without content are called empty elements. Empty elements can be closed in the start tag. <br> is an empty element without a closing tag (it defines a line break).
- 12. Empty HTML Elements In XHTML, XML, and future versions of HTML, all elements must be closed. Adding a slash to the start tag, like <br/>, is the proper way of closing empty elements, accepted by HTML, XHTML and XML.
- 13. Lowercase Tags HTML tags are not case sensitive: <P> means the same as <p>. Plenty of web sites use uppercase HTML tags in their pages. the World Wide Web Consortium (W3C) recommends lowercase in HTML 4, and demands lowercase tags in future versions of (X)HTML.
- 14. HTML Attributes • HTML elements can have attributes • Attributes provide additional information about the element • Attributes are always specified in the start tag • Attributes come in name/value pairs like: name="value"
- 15. HTML Attributes <body bgcolor="#E6E6FA"> <font face="verdana" size="2" color="blue"> This is some text! </font>
- 16. Text Formatting <p><b>This text is bold</b></p> This text is bold <p><big>This text is big</big></p> This text is big <p><i>This text is italic</i></p> This text is italic
