css3 - So I have an HTML file with a paragraph and I need to break into three lines BUT i can only modify the CSS. How do I pull this off? (code below) -

<form method="post" id="contactform" action="#">         <fieldset>             <legend>newsletter signup</legend>             <p>to sign our fabulous campaign of useless information never, ever read, please submit email address here.</p>             <label for="email" id="emaillabel">email</label>             <input type="text" id="email" />             <input type="button" name="submit" value="submit" id="submitbutton"/>         </fieldset>     </form> 

so need paragraph on 3 separate lines has done css.

if need in 3 line don't care lines break:

p{   width: 300px; } 

but won't allow specify in sentence line breaks.
