If you are used HTML syntax, you may write your <br> tags as in the paragraph below:

<p>

I love the way you look at me,<br>

Your eyes so bright and blue.<br>

I love the way you kiss me,<br>

Your lips so soft and smooth.<br>

</p>

But that paragraph will be invalid as XHTML documents, because all 4 <br> are not closed. You should change it to:

<p>

I love the way you look at me,<br/>

Your eyes so bright and blue.<br/>

I love the way you kiss me,<br/>

Your lips so soft and smooth.<br/>

</p>
