Thanks, that looks way better, especially since we switched logos!

I needed to remove a lot of the custom style because Docsy had a breaking change moving to Bootstrap 5 in v0.7.0 and most of the style written was broken https://github.com/google/docsy/releases/tag/v0.7.0. I hope this time, this is more resilient for future updates.

I have a few first comments, but I think this PR should be a draft given you have a lot of placeholders and links that don't work on the page, so I'll convert it to draft as of now, you can mark it ready once you want a full review.

I would say as long as the homepage doesn't affect how the rest of the documentation looks (typically the global font change isn't great) I'm super fine with it and happy that someone who can write serious design and CSS rewrote that.

Sorry I know this is a little late in the process, but can we had a section like the one below to the website under the first section? "We are a proud CNCF project"

Some people don't realize this and it would be great to get on the website

Just fyi, I updated Docsy and Hugo version, you might need to rebase on top of main (for that PR #2497). I checked, and nothing breaks on your homepage, you just need to merge some commits during the rebase but it should be trivial, just accept both changes all the time.

Can you squash the commits into the first one maybe? thanks!!

[mtardy]

I was going to merge but I did some checks and found some issues! Again if you fix this, feel free to squash your commits into one. Thanks a lot, overall it's night and day with the current homepage.

Thanks, it looks fantastic! :)
