Cipta HTML untuk paparan Navbar

<React.Fragment>
      <nav className={`fixed inset-x-0 top-0 z-50 flex items-center justify-center h-[60px] py-3 [&.is-sticky]:bg-white  border-b border-slate-200  [&.is-sticky]:shadow-lg [&.is-sticky]:shadow-slate-200/25 navba ${navClass}`} id="navbar">
        <div className="container 2xl:max-w-[90rem] px-4 mx-auto flex items-center self-center w-full">
          <div className="mx-auto">

"active" : ""}`}
                  onClick={() => handleLinkClick("/Home")}
                >
                  Home</a>
              </li>
              <li>
                <a href="#features"
                  className={`block md:inline-block px-4 md:px-3 py-2.5 md:py-0.5 text-15 font-medium text-slate-800 transition-all duration-300 ease-linear hover:text-red-500 [&.active]:text-red-500 dark:text-zink-100 dark:hover:text-red-500 dark:[&.active]:text-red-500 ${activeLink === "/Features" ?

                  onClick={() => handleLinkClick("/Features")}
                >
                  Layanan Kami</a>
              </li>
            </ul>
          </div>

        </div>
      </nav>
      <section className="relative mt-[60px] h-[800px] bg-yellow-600" id="home">
        <div className="flex items-center justify-center h-full">
          HOME
        </div>
        </section>
      <section className="relative h-[800px] bg-green-600" id="features">
        <div className="flex items-center justify-center h-full">
          FEATURES
        </div>
      </section>
    </React.Fragment>

Fungsi Tatal

Fungsi ini digunakan untuk menukar status bar navigasi kepada melekit, dan juga menambah animasi yang lancar supaya proses penukaran halaman adalah baik

  const [navClass, setNavClass] = React.useState<string>('');

  const scrollNavigation = () => {
    var scrollUp = document.documentElement.scrollTop;
    if (scrollUp >= 50) {
      setNavClass('is-sticky');
    } else {
      setNavClass('');
    }
  };


  React.useEffect(() => {
    window.addEventListener('scroll', scrollNavigation, true);
    document.documentElement.classList.add("overflow-x-hidden", "scroll-smooth", "group");

    return () => {
      window.removeEventListener('scroll', scrollNavigation, true);
      document.documentElement.classList.remove("overflow-x-hidden", "scroll-smooth", "group");

    };
  }, []);

Tetapkan fungsi menu Aktif

Fungsi ini berfungsi untuk menukar kelas aktif dalam menu, dan mengarahkan halaman mengikut menu yang diakses

  const [activeLink, setActiveLink] = React.useState<string>("/Home");
  const handleLinkClick = (target: string) => {
    setActiveLink(target);
  };

Skrip lengkap adalah seperti berikut

import React from "react"

function App() {



  const [navClass, setNavClass] = React.useState<string>('');

  const scrollNavigation = () => {
    var scrollUp = document.documentElement.scrollTop;
    if (scrollUp >= 50) {
      setNavClass('is-sticky');
    } else {
      setNavClass('');
    }
  };


  React.useEffect(() => {
    window.addEventListener('scroll', scrollNavigation, true);
    document.documentElement.classList.add("overflow-x-hidden", "scroll-smooth", "group");

    return () => {
      window.removeEventListener('scroll', scrollNavigation, true);
      document.documentElement.classList.remove("overflow-x-hidden", "scroll-smooth", "group");

    };
  }, []);



  const [activeLink, setActiveLink] = React.useState<string>("/Home");
  const handleLinkClick = (target: string) => {
    setActiveLink(target);
  };



  return (
    <React.Fragment>
