Refining Landing Page

I hope you don't laugh. I created a website, but I'm down, I don't have time to finish it. It's almost ready, I'll add content myself. You're required to do 1. Put a smooth scrolling of the horizontal menu on the links (single page site) 2. The effect of flipping in point (see the projects we have completed) 3. Check the php file of the feedback form, 4. Suggestions and complaints are welcome)

I can’t get the index attached, let’s post it in the archive.
