Floating my button to the right is not working - html

Question

I´m here with a strange situation, trying to float my button input[type="submit"] to the right.
I have space there and so I´m floating the button to the right to stand beside my input text.
But the float is not working and the button is not going, in any way, to the right.

<form action="" name="newsletter" method="post" enctype="multipart/form-data">
<label id="email-label2">
<i class="fa fa-envelope-o"></i>
<input type="text"id="email2" name="email" placeholder="e-mail" required/>
</label>http://jsfiddle.net/#save
<br />
<label id="submit">
<input type="hidden" name="news_register" value="register" />
<input type="submit" name="register" value="Register" src="" />

</form>
</div>
</footer>

Answer 1

You had a couple of problems with the semantics and broken tags. I fixed it up and and updated the CSS:

Tips:
Don't place input fields inside label elements. Labels should describe the input field and sit above them. <label for="email">Enter your email</label>
Float the container with your items in it, the containers will stack against each other.
Clear your floats ;)
Read CSS Mastery by Andy Budd, its a great foundation.

Answer 2

Ignoring the float, your layout looks like this:
/----------------Container------------------\
| [Text input here] |
| [Submit button here] |
\-------------------------------------------/
Now let's factor in the float:right:
/----------------Container------------------\
| [Text input here] |
| [Submit button here] |
\-------------------------------------------/
See how even though there's room, it's not magically moving up.
Now, let's try moving the submit button to be before the text input in your layout:
/----------------Container------------------\
| [Submit button here] |
| [Text input here] |
\-------------------------------------------/
Result with float:
/----------------Container------------------\
| [Text input here] [Submit button here] |
\-------------------------------------------/
Yay! But... having the submit button before the text is not very semantic at all. What else can be done?
Well, you could try removing the <br /> tag.
Adjust margins as needed!
