HTML
- HTML pages are text documents.
- XX HTML uses tags (characters that sit inside angled brackets) to give the information they surround special meaning.
- XX Tags are often referred to as elements.
- XX Tags usually come in pairs.
- The opening tag denotes the start of a piece of content; the closing tag denotes the end.
- XX Opening tags can carry attributes, which tell us more about the content of that element.
- XX Attributes require a name and a value.
- XX To learn HTML you need to know what tags are available for you to use, what they do, and where they can go.
