In HTML words enclosed in brackets, < > are called HTML tags. HTML is not case sensitive.
Most HTML tags come in pairs, a beginning and a closing. Closing tags always include a forward slash. Example:
The main sections of a basic HTML page are set off by tags. The head, title, meta, style, and body sections are located within the opening and closing HTML tags.
The TITLE in the heading section is what appears on the bar at the top of your browser window. It is also used by search engines to locate your page.
META tags are also used by some search engines.
STYLE tags are used to characterize your website using different font sizes, colors, backgrounds, etc.
The BODY section contains all of the codes for the page that will be displayed in the browser window.
