Navbar Stick auf Header, wenn

Question

Hallo Jungs Scrollen so ich versuche, um einen Effekt zu erhalten, arbeiten waren die navbar ist in der Mitte der Seite und der Benutzer wird nach unten scrollen, als er den navbar trifft es an die Spitze haften bleiben sollte Die Seite. Beispiel dafür: here Sie können sehen, wenn der Benutzer scrollt nach unten und trifft die Navbar es Stick und es ist eine schöne langsame Wirkung.

Ich habe meins zu arbeiten, aber es fühlt sich klirrend an, damit meine ich, dass es sofort nach oben geht, im Gegensatz zu dem Beispiel, das sehr glatt ist und glatt an der Spitze klebt, während meins sehr hart ist.

Jede mögliche Hilfe würde groß sein.

Answer 1

Sie müssen nur hinzufügen, auf Ihr Stil:

.affix + .parallax1 { 
    margin-top: 70px; 
} 

Die Klasse .affix zeigt an, dass das Nav an der Spitze klebt. Wenn also .affix auf nav vorhanden ist, müssen Sie den Rand oder Abstand auf parallax1 setzen, damit sich der HALLO THERE-Text nicht hinter dem Nav versteckt.

Bearbeiten der Geige:

.parallax { 
 
    background-color: Black; 
 
    min-height: 700px; 
 
    background-attachment: fixed; 
 
    background-position: center; 
 
    background-repeat: no-repeat; 
 
    background-size: cover; 
 
} 
 

 
.parallax1 { 
 
    background-color: Red; 
 
    min-height: 700px; 
 
    background-attachment: fixed; 
 
    background-position: center; 
 
    background-repeat: no-repeat; 
 
    background-size: cover; 
 
} 
 

 
/* Add this */ 
 
.affix + .parallax1 { 
 
    margin-top: 70px; 
 
} 
 

 
.navbar { 
 
    margin-bottom: 0px; 
 
    left: 0; 
 
    top: 0; 
 
    width: 100%; 
 
    list-style: none; 
 
    height: 70px; 
 
    z-index: 1

Answer 4

Der Grund für das gewünschte Beispiel so glatt funktioniert, ist, weil es eine smoothScroll Bibliothek nutzt. Ich habe es einfach in die Beispielgeige eingefügt, die Sie zur Verfügung gestellt haben, und es funktioniert viel mehr wie die Demo-Seite, die Sie gezeigt haben, überprüfen Sie es here. Sie brauchen keinen Code auf Ihrer Seite hinzuzufügen, da die Bibliothek bereits initialisiert wird, sobald die Seite fertig geladen:

addEvent(wheelEvent, wheel); 
addEvent('mousedown', mousedown); 
addEvent('load', init); 

Lassen Sie mich wissen, wenn Sie Fragen haben:)

Answer 5

Glatte klebrige navbar Es benutzt jquery 2. Hoffe das funktioniert für Ihre Tests. Verfolgt Navbar auf allen Bildschirmgrößen.

var navOffset, scrollPos = 0; 
 

 
function sticky() { 
 
    if (!$(".navbar").hasClass("fixed")) { 
 
    navOffset = $(".navbar").offset().top; 
 
    } 
 
} 
 

 
sticky(); 
 

 
$(window).scroll(function() { 
 
    scrollPos = $(window).scrollTop(); 
 
    if (scrollPos >= navOffset) { 
 
    var ht = $(".navbar").outerHeight() + 10; 
 
    $(".navbar").addClass("navbar-fixed-top"); 
 
    $(".nav-placeholder").css({ 
 
     'height': ht + "px", 
 
     'display': 'block' 
 
    }); 
 
    } else { 
 
    $(".navbar").removeClass("navbar-fixed-top"); 
 
    $(".nav-placeholder").css({ 
 
     'height': 0, 
 
     'display': 'none' 
 
    }); 
 
    } 
 
});

.parallax {
