"Create a paragraph element below your h2 element, and give it the text \"Hello Paragraph\". As soon as you create the opening <code><p></code> tag, one of our tests will pass (since this is valid HTML). Be sure to close the element by adding a closing <code></p></code> tag.",
"Note that <code><br/></code> has no closing tag. It is a <code>self-closing</code> element. See how a forward-slash precedes the closing bracket?",

"That's one way to add style to an element, but a better way is by using <code>Cascading Style Sheets (CSS)</code>.",
"At the top of your code, create a <code>style tag</code> like this: <code><style></style></code>",
"Inside that style element, you can create a <code>css selector</code> for all <code>h2</code> elements. For example, if you wanted all <code>h2</code> elements to be red, your style element would look like this: <code><style>h2 {color: red;}</style></code>",
"Note that it's important to have <code>opening and closing curly braces</code> (<code>{</code> and <code>}</code>) around each element's style. You also need to make sure your element's style is between the opening and closing style tags. Finally, be sure to add the semicolon to the end of each of your element's styles."
