How to change scrollbar when using Tailwind (next.js/react)

I'm using Tailwind (react/next) and struggle to change the way my scrollbar looks.

It's a single page application and I have been trying to create custom CSS to apply to the first div in my index file, like this:

<div className="no-scroll"> <<<<<<<--------- Adding custom css here
      <Head>
        <title>Oscar Ekstrand</title>
        <link rel="icon" href="/images/favicon.ico" />
    
      </Head>
      
      <main className="flex flex-col no-scroll">
        <section ref={heroref}>
          <Hero scrollToContacts={scrollToContacts} />
        </section>

        <section ref={offeringref}>
          <Offering />
        </section>
        <section ref={processref}>
          <WhatIDo />
        </section>

        <section ref={biographyref}>
          <CvBar />
        </section>
        <section ref={skillsetref}>
          <Skillset />
        </section>
      </main>
      <section ref={contactsref}>
        <Footer />
      </section>
    </div>

I can get custom CSS classes to work for things like buttons, both with a "plugin-approach" and having a global style sheet. (https://play.tailwindcss.com/zQftpiBCmf)

But I can't understand how to change the look of my scrollbar.

Anyone got an idea?

Solution

Tailwind CSS doesn't provide a built-in way to customise the scrollbar styling. However, you can use the various ::-webkit-scrollbar pseudo-elements to style it.

Tailwind playground link: https://play.tailwindcss.com/5samiwyr4v.

@layer utilities {
  .scrollbar::-webkit-scrollbar {
    width: 20px;
    height: 20px;
  }

  .scrollbar::-webkit-scrollbar-track {
    border-radius: 100vh;
    background: #f7f4ed;
  }

  .scrollbar::-webkit-scrollbar-thumb {
    background: #e0cbcb;
    border-radius: 100vh;
    border: 3px solid #f6f7ed;
  }

  .scrollbar::-webkit-scrollbar-thumb:hover {
    background: #c0a0b9;
  }
}
