Again your project is wonderful, very organized, and well structured.
I would like to point 3 little things:
there is a little typo (line 44): the "addres" is missing one "s" (should be "address");
the image's alt's are not edited;
in your code all "a" are set to have no text decoration, but on the footer, the "Legal Privacy Security" are all supposed to have a different color, so they can pop out!
Once again, congratulations on the amazing project.
Index.html: Line#35: Don't put h3 inside a div, It's useless. Remove the div.
Index.html: Either use or Don't use both inside each other.
Style.css: Don't make the code like this (main .login .form) only use (.form)
