Looks great. The styling is very well done. The only minor critique I have is that the quotebox looks a little small right after your responsive breakpoint. Good work!
thanks @Aaronms! Adjusted the size for the quotebox based on your feedback!
Great, adding that extra breakpoint makes it look a lot better on mid-sized screens. Keep up the good work!
Beautiful and simplistic Design. You could enclose your Quote section inside a Div with a fixed height, so that the button stays in its position.
