Responsive Fylo landing page using ReactJS | Mobile first design

Implementing this challenge's solution with React was just amazing, I coded this design with the First Mobile concept. I got some problems with the 2 hero images on the responsive part, but somehow I solved them by reducing the width of the image to 50%, also I faced some issues with the font size of paragraphs as I don't have the original design(free mode). One problem remains unsolved: the logo image has by default black color, but in the design, I see the logo on the footer has white color, I tried to give it color: white, but that didn't solve the problem, I'm waiting forward for a solution. Your comments are welcome.
