As per my comment. Use CSS. This should get you on the correct path:
css:
.contact-form .field label { width: 100px; display:inline-block; vertical-align: top; }
.contact-form .req { color: red; }
.contact-form .field .textbox { width: 180px; }
html:
<div class="contact-form">
<form action="sending.php" method="post" name="Contact Form" id="form1" onsubmit="MM_validateForm('Name','','R','Email','','R','Device','','R','Message','','R')return document.MM_returnValue" encytype="text/plain">
<div class="field">
<label for="Name">Name:</label>
<input name="Name" type="text" id="Name" class="textbox" />
<span id="req_3" class="req">*</span>
</div>
<div class="field">
<label for="Email">Email:</label>
<input name="Email" type="text" id="Email" class="textbox" />
<span id="req_3" class="req">*</span>
</div>
<div class="field">
<label for="Message">Review:</label>
<textarea name="Message" cols="35" rows="7" id="Message" placeholder="Y U SO BROKE MR. THINGY D;"></textarea>
</div>
<div>
<input name="Submit" type="submit" id="Submit" value="Submit" />
</div>
</form>
</div>
