The input and the button works correctly on the same line, but the input size is small and has room for it to be larger.
I would like it to be 100% full size, following the line below the input and button, you see? My HTML is:
<form class="form-inline">
<div class="form-group">
<input type="email" class="form-control emailNewsletter" placeholder="Your Email goes here">
</div>
<div class="form-group">
<button type="submit" class="btn btn-default">Sign Up!</button>
</div>
</form>
