Is the Vercel blog open-source?

Hi guys is the vercel blog open source do they have the source code?
i kinda like the ui with those backround lines.is there any way i could replicate it?

The blog is not open source unfortunately, but are you talking about the cards like this with soft outlines?

There’s a trick to this kind of layout where you can use CSS grid with a 1px gap that reveals the color beneath

<div className="grid p-[1px] gap-[1px] bg-gray-300"> // gray outline
  {cards.map(card => (
    <div className="h-32 w-24 bg-white" /> // white cards
  ))}
</div>

nope not this i kinda need to get this backround


those backround lines those ones.how do i create and customize that?
