Front end HTML / CSS website only

THESE ARE THE SIGNED OFF VISUALS - https://invis.io/NBI2CI5DUGC
I need these translated into a HTML / CSS website that is 100% pixel perfect.
If you have not seen these visuals please do NOT reply to this post.

Home page - animate 3 circles to come in one after another - please advise on animation before building
Menu - expand full browser height as visual 2
About - when scrolling content comes up into view - logos animated fade in
Services - Internal menu left - when clicked content appears right as visual
Contact - form and captcha
