@shashigharti
Let's remove the "Frictionless Projects" section from the main page -- it's already outdated and will be loosing actuality even more going forward. Without this section it will looks more neutral, software and standards, for anyone who works with data etc

@shashigharti

@shashigharti
I mean this one - #830 (comment)

In-general we're splitting #828 into two parts. In this PR we are addressing the most critical branding parts

[shashigharti]

Thanks @roll and @lucpretti and I will make the changes.

[shashigharti]

@lucpretti @roll I made the changes, and here is the output after new changes.

Looks great, thank you @shashigharti!

Could we just decrease the FD logo size in the footer a little bit to normalise it with the other two?

[shashigharti]

@lucpretti I have made the changes.

[shashigharti]

Thanks @lucpretti . Shall I merge it?

[lucpretti]

For me it's good to go.
