Notes To Consider
• HTML tags are not case-sensitive.• Words enclosed in an angle
brackets, < >, are the codes or tags
• Tags always come in pairs. The second pairs has a slash (/) before the tag inside the bracket.• The slash means “stop”
• The tag with a slash is called the CLOSING TAG, while the one without a slash is called the OPENING TAG.
• The tag <html> and </html> must be placed at the start and end of every document.
• What you type in between the <body> and </body> tag are the content that will appear on the Web page.
• The text in between the <title> and </title> tag will appear on the title bar of a web browser.
