In dieser Sitzung erstellen wir eine Sticky-Navigationsleiste mit Tailwind CSS und React JS.
Sie können den Installationsprozess für React und Tailwind CSS im vorherigen Artikel sehen
Lassen Sie uns sofort den Code für die Navigationsleiste erstellen
<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"> <ul id="navbar7" className={`absolute inset-x-0 z-20 items-center py-3 bg-white shadow-lg dark:bg-zink-600 dark:md:bg-transparent md:z-0 navbar-menu rounded-b-md md:shadow-none md:flex top-full ltr:ml-auto rtl:mr-auto md:relative md:bg-transparent md:rounded-none md:top-auto md:py-0`}> <li> <a href="#home" 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 === "/Home" ? "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" ?

Diese Funktion wird verwendet, um den Status der Navigationsleiste auf „Sticky“ zu ändern und außerdem flüssige Animationen hinzuzufügen, damit der Seitenwechselvorgang reibungslos verläuft
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"); }; }, []);
Diese Funktion dient dazu, die aktive Klasse im Menü zu ändern und leitet die Seite entsprechend dem Menü, auf das zugegriffen wird
const [activeLink, setActiveLink] = React.useState<string>("/Home"); const handleLinkClick = (target: string) => { setActiveLink(target); };
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> <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"> <ul id="navbar7" className={`absolute inset-x-0 z-20 items-center py-3 bg-white shadow-lg dark:bg-zink-600 dark:md:bg-transparent md:z-0 navbar-menu rounded-b-md md:shadow-none md:flex top-full ltr:ml-auto rtl:mr-auto md:relative md:bg-transparent md:rounded-none md:top-auto md:py-0`}> <li> <a href="#home" 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 === "/Home" ?
