1. lecture summary
This lecture has two distinct parts:
- In the first part, a problem will first be posed that we will consider how to solve. On the next slide you will see two identical pieces of web code that are rendered in two completely different styles. This works because - as discussed in the pre-assigned reading for this lecture - style information is not encoded into web pages but is usually placed in an external style sheet. The first part of the lecture will explain how and why you should do this. It will help you create your own style sheet for the simple web page we built in lecture 1.
- In the second part, we will start to think about what the topic of your web site is going to be. You will see how it is not enough simply to decide on a subject for the site: you need to think about why people might visit it. Your site may have to look different depending on the answer to that question. You may also have to think about splitting it in distinct parts if there are competing answers. More details later.

2. what is not covered
This lecture discusses text formatting tags, which are (by far) the most widely-used family of tags. But it will not spend time on the details of individual tags.
Remember that these lectures are complemented by the online teaching materials. For details on how to define and use specific text formatting tags - particularly the more complex ones like list tags - you should refer to these pages after the lecture.
Also, though we cover the subjects of fonts and colours in the lecture, we won't do so in detail. However, these are important things to understand if you want a usable, good-looking web site. Therefore, it's strongly recommended that you read the following topic pages as soon as you can after completing this lecture (while the demonstrations are fresh in your mind):
