In-Depth Information
Save and test your page in a browser. If you notice that the Trillium Media Design text
seems to crowd the left margin, add a   nonbreaking space special character in
the body of the Web page after the opening <h1> tag.
Configure the h2 Selector
Configure the CSS rule to use the same font typeface as the h1 selector.
h2 { background-color: #AEAED4;
color: #191970;
font-family: Georgia, "Times New Roman", serif;
Add a New Paragraph Element Selector
Configure text in paragraphs to display just slightly smaller than the default text size.

ul { font-weight: bold; }

classe s, or id s) by listing the selectors in front of the rule. The code sample below shows the
font-size of 1em being applied to both the paragraph and line item elements.
p, li { font-size: 1em; }
