3 FUNDAMENTAL What is HTML? HTML is a language for describing web pages.
HTML stands for Hyper Text Markup Language HTML is not a programming language, it is a markup language. A markup language is a set of markup tags. HTML uses markup tags to describe web pages. Company Logo

4 FUNDAMENTAL HTML Tags: HTML markup tags are usually called HTML tags
HTML tags are keywords surrounded by angle brackets like <html> HTML tags normally come in pairs like <b> and </b> The first tag in a pair is the start tag, the second tag is the end tag. Start and end tags are also called opening tags and closing tags. Company Logo

5 FUNDAMENTAL HTML Document = Web Page
HTML documents describe web pages, it contain HTML tags and plain text Structure of the web page: <html> <head> information of the web page</head> <body> content display on browser </body> </html> Company Logo

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 Company Logo

We use a plain text editor (like Notepad) to edit HTML. This is the best way to learn HTML. However, professional web developers often prefer HTML editors like FrontPage or Dreamweaver, instead of writing plain text. HTM or HTML Extension? When you save an HTML file, you can use either the .htm or the .html extension. With new software it is perfectly safe to use .html. Company Logo

8 HTML ELEMENTS HTML Elements: An HTML element is everything from the start tag to the end tag: Start tag * Element content End tag * <p> This is a paragraph </p> <a href="default.htm"> This is a link </a> <br /> Company Logo

An HTML element starts with a start tag / opening tag and ends with an end tag / closing tag The element content is everything between the start and the end tag Some HTML elements have empty content Empty elements are closed in the start tag Most HTML elements can have attributes Company Logo

10 HTML ELEMENTS Nested HTML Elements
Most HTML elements can be nested (can contain other HTML elements). HTML documents consist of nested HTML elements. 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 Company Logo

11 HTML ELEMENTS Example: Explain: <html>
<body> <p>This is my first paragraph</p> </body> </html> Explain: The <html> element defines the whole HTML document. The <body> element defines the body of the HTML document. The <p> element defines a paragraph in the HTML document Company Logo

12 HTML ELEMENTS 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“. Attribute values should always be enclosed in quotes Example <a href=“ is a link </a> Company Logo

13 HTML ELEMENTS Below is a list of some attributes that are standard for most HTML elements: Attribute Value Description class class_rule or style_rule The class of the element id id_name A unique id for the element style style_definition An inline style definition title tooltip_text  A text to display in a tool tip Company Logo

Headings are defined with the <h1> to <h6> tags. <h1> defines the largest heading. <h6> defines the smallest heading. Example <h1>This is a heading1</h1> <h2>This is a heading2</h2> <h3>This is a heading3</h3> Browsers automatically adds an empty line before and after headings. Company Logo

<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> </body> </html> Company Logo

The <hr /> tag is used to create an horizontal rule (line). Example: <html><body> <p>The hr tag defines a horizontal rule:</p> <hr /> <p>This is a paragraph</p> </body></html> Company Logo

17 <HR Align=”directtion” Width= “Value” Size=value color=#rrggbb>
BASIC HTML TAGS Optional Attributes of the <HR> tag: <HR Align=”directtion” Width= “Value” Size=value color=#rrggbb> Example: <HR Align=CENTER Size=12 Width=100% color=RED> <HR Align=CENTER SizeE=6 Width=50% color=GREEN> <HR Align=CENTER Size=3 Width=25% color=BLUE> <HR Align=CENTER Size=1 Width=10% color=YELLOW> Company Logo

Comments can be inserted in the HTML code to make it more readable and understandable. Comments are ignored by the browser and are not displayed. Example <html><body> <!--This comment will not be displayed--> <p>This is a regular paragraph</p> </body></html> Company Logo

Paragraphs are defined with the <p> tag Browsers automatically adds an empty line before and after paragraphs. Example: <html><body> <p>This is a paragraph. <p>Don't forget to close your HTML tags!</p> </body></html> Company Logo
