Product landing page feedback of G402 mouse

Hi,
I have created a replica of Logitech mouse G402 HYPERION FURY landing page. I created with flex-box the whole page.

Here is the GitHub link: https://github.com/prashant-rajoriya/FCC-Product-Landing-Page.

Also here is working link: https://prashant-rajoriya.github.io/FCC-Product-Landing-Page/

Love the design and layout of the page. But there is a problem with the responsiveness of the page on smaller screen widths. Some navbar content start to spill out,

And there is also lot of white space on the right side of the page on smaller screen widths. This is probably due to the non-responsiveness of the email input and submit button at the bottom of the page. Adding a media query should fix it.

Hope this helps you.
