- Tags usually come in pairs. The opening tag denotes the start of a piece of content; the closing tag denotes the end.
- Opening tags can carry attributes, which tell us more about the content of that element.
- Attributes require a name and a value.

- Each time the script runs, it might only use a subset of all the instructions.

- To approach writing a script, break down your goal into a series of tasks and then work out each step needed to complete that task (a flowchart can help).
