Product landing page project#3 feedbak

Please feedback on my page.

Hard to see your page @min9000 but it looks good. Things to revisit;

  • Verify your email addr with codepen so we can see your page full screen.
  • Do not use internal styling. Keep all your styling external.
  • Run your HTML code through the W3C validator.
    • There are HTML coding errors you should be aware of and address.
    • Since copy/paste from codepen you can ignore the first warning and first two errors.
  • Check that the user has entered a valid email addr. Throw an HTML5 validation error if not.
    • You learned to do this when coding the survey form
  • Make your page responsive. Remember, the R in RWD stands for Responsive
    • There’s a horizontal scrollbar on smaller screens

Thank you for your feedback on my 3 works!
I didn’t noticed grammar errors, so I will try to fix the things you taught me from now on.

Since I am not a native English speaker, I was also glad that you pointed out my language mistakes.
Thank you!
