In this lesson, you will learn about the different types of selectors and how to use them.

Setting Up the HTML Code

Selectors are one of the most important aspects of CSS because they are used to "select" elements on an HTML page so that they can be styled. The HTML code for this lesson is shown in Listing 3.1.

Listing 3.1 HTML Code Containing Markup for Lesson 3

<body>
<div id="content">
 <h1>
  Heading here
 </h1>
 <p class="intro">
  Lorem ipsum dolor sit amet.
 </p>
 <p>
  Lorem ipsum dolor <a href="#">sit</a> amet.
 </p>
</div>
<div id="nav">
 <ul>
  <li><a href="#" class="intro">item 1</a></li>
  <li><a href="#">item 2</a></li>
  <li><a href="#">item 3</a></li>
 </ul>
</div>
<div id="footer">
 Lorem ipsum dolor <a href="#">sit</a> amet.
</div>
</body>

What Is a <div>?

The <div> element is a generic container that can be used to add structure to an HTML document. Although it is a block level element, it does not add any other presentation to the content.

For this lesson, the <div> element has been used to contain logical divisions of content, such as navigation and footer information.

These divisions of content can then be styled to suit your needs using descendant selectors, which are covered later in this lesson.

This privacy notice provides an overview of our commitment to privacy and describes how we collect, protect, use and share personal information collected through this site. Please note that other Pearson websites and online products and services have their own separate privacy policies.

Collection and Use of Information


To conduct business and deliver products and services, Pearson collects and uses personal information in several ways in connection with this site, including:

Questions and Inquiries

For inquiries and questions, we collect the inquiry or question, together with name, contact details (email address, phone number and mailing address) and any other additional information voluntarily submitted to us through a Contact Us form or an email. We use this information to address the inquiry and respond to the question.

For orders and purchases placed through our online store on this site, we collect order details, name, institution name and address (if applicable), email address, phone number, shipping and billing addresses, credit/debit card information, shipping options and any instructions. We use this information to complete transactions, fulfill orders, communicate with individuals placing orders or visiting the online store, and for related purposes.

Surveys

Pearson may offer opportunities to provide feedback or participate in surveys, including surveys evaluating Pearson products, services or sites. Participation is voluntary. Pearson collects information requested in the survey questions and uses the information to evaluate, support, maintain and improve products, services or sites, develop new products and services, conduct educational research and for other purposes specified in the survey.

Service Announcements

On rare occasions it is necessary to send out a strictly service related announcement. For instance, if our service is temporarily suspended for maintenance we might send users an email. Generally, users may not opt-out of these communications, though they can deactivate their account information. However, these communications are not promotional in nature.

Customer Service

We communicate with users on a regular basis to provide requested services and in regard to issues relating to their account we reply via email or phone in accordance with the users' wishes when a user submits their information through our Contact Us form.
