Web Hosting-product landing page

I don’t know about appearance failure. I don’t what to do in CSS I just changed the codes as in the primary program
please provide a solution
I don’t know the problem in the program

If I were you,

I would start off by coding one block at a time with html. Before you proceed with any other sections, try to make your navbar work first. Then your title, email form, etc…

thanks bro I will try your ideas
