In the registration / registration window, I need to separate two buttons with text like this.

With my HTML code:
<button class="facebookSux">Ingresa con Facebook</button> <label>o si prefieres</label> <button class="register">Regรญstrate con tus datos</button>
How to get horizontal line for label using CSS only?
One solution that I reviewed is to use a linear gradient appropriately, but this requires a more elegant way.
