Updated code syntax

Use tab isntead of ``` to indicate <pre><code>
Include parsed README.md as a <dialog>
Use .logo & .logo:hover istead of img or svg

Allows for more elements to get the transition
Moved <dialog> close buttons to top
New logo for copyleft
Revert old stylesheets

Back to applying trasnition/transform to .logo svg|img
Update inclusion and order of logos/icons
