Now try this:
<title>My First Page</title>
<h1>Welcome to My Page!</h1>
<h3>This is my very first web page.</h3>
<p>Not bad for a first attempt.<br />
I can also introduce line breaks</p>
<p><strong>This is bold text</strong></p>
<p><em>This is italic text</em></p>
<p><strong><em>This is bold, italic, text</em></strong></p>
You have added a horizontal rule by using the
<hr /> tag after your first heading.
Note that, like
<br />, the horizontal rule tag is a composite tag.
