Please review my third project, the product landing page

Kindly review my project on product-landing page. https://codepen.io/zenoalive/pen/QWaryzW

The very first part looks good. But the section which says ‘Subscribe to our newsletter’ looks more like a button on the whole. I would increase its height to make it look more like a section. Also choose some lighter blue/color for it so that the black text stands out more. Check out the color compatibility and complementary colors course under Applied Visual Design on fCC.

The three sections About Us, Our Products, Contact Us should be limited to the middle of the page and not span its entire width. Enclose these three sections in a div if you have not already done that and then give a padding to that div so that these sections are pushed to the center of the page.

I would also align the header of each of these sections to the center of the content.

Thanks a lot. I will work on the issues
