Recently i have used revolution slider for one of our responsive website design. It it so good, but sometimes we will get css errors. It is because of wrong classes. It is little bit problem to find the exact class to change color or font size in revolution slider. But when really check it with 'inspect element' then you can find the exact class.

Revolution slider banner features are:
Full width,
responsive,
mobile friendly,
fully search engine optimized.

One of the major advantage of this slider is we can instantly change transition effect within html code only.
I suggest revolution slider for your responsive web design applications.
