Bootstrap navbar opacitiy using scrolling-nav js - javascript

Im using scrolling-nav-js Scrolling nav to animate padding and fix my navbar to the top of my page and i want to give the navbar a subtle opacity animation. How can i add the transition to change the opacity property?
I have the following code in the JS and the CSS files:
//jQuery to collapse the navbar on scroll
$(window).scroll(function() {
if ($(".navbar").offset().top > 50) {
$(".navbar-fixed-top").addClass("top-nav-collapse");
} else {
$(".navbar-fixed-top").removeClass("top-nav-collapse");
}
});
//jQuery for page scrolling feature - requires jQuery Easing plugin
$(function() {
$('a.page-scroll').bind('click', function(event) {
var $anchor = $(this);
$('html, body').stop().animate({
scrollTop: $($anchor.attr('href')).offset().top
}, 1500, 'easeInOutExpo');
event.preventDefault();
});
});
#media(min-width:767px) {
.navbar {
padding: 20px 0;
-webkit-transition: background .5s ease-in-out,padding .5s ease-in-out;
-moz-transition: background .5s ease-in-out,padding .5s ease-in-out;
transition: background .5s ease-in-out,padding .5s ease-in-out;
}
.top-nav-collapse {
padding: 0;
}
}

Nevermind :) adding this is perfect.
transition: background .5s ease-in-out,padding .5s ease-in-out, opacity .5s ease-in-out,opacity .5s ease-in-out;
and
.top-nav-collapse {
padding: 0;
opacity: 0.6;

Background-image transition not woking in Firefox (-moz-)

I dont get the fade of the background picture to work in Firefox but any other Browser. Help is appreciated!
Just click on the image.
$(document).ready(function(){
$(".click_me").click(function(){
$('.click_me').css('background-image', 'url(https://placekitten.com/500/500)');
});
});
.click_me {
height:500px;
width:500px;
opacity: 1.0;
background-image: url(http://placekitten.com/g/500/500);
-webkit-transition: background-image 700ms linear;
-moz-transition: background-image 700ms linear;
-o-transition: background-image 700ms linear;
-ms-transition: background-image 700ms linear;
transition: background-image 700ms linear;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="click_me"></div>
Since you are using jQuery already why don't use its animate function instead of CSS transitions, this will do the trick for you very easily.
$(document).ready(function() {
$(".click_me").one('click', function() {
$(this).animate({
opacity: 0
}, 'fast', function() {
$(this)
.css({
'background-image': 'url(https://placekitten.com/500/500)'
})
.animate({
opacity: 1
});
});
});
});
.click_me {
height: 500px;
width: 500px;
opacity: 1.0;
background-image: url(http://placekitten.com/g/500/500);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="click_me"></div>

Scroll anchor not activating

When I scroll and the anchor touches the top of the window, the background color of the box is supposed to change but I can't seem to get it to work properly.
https://jsfiddle.net/6p2pnnq4/1/
var scrollFn = function() {
var targetOffset = $(this).find(".anchor-point")[0].offsetTop;
console.log('Scrolling...');
if ($(this).scrollTop() > targetOffset) {
$(this).find(".footer_wrap").addClass("topper");
} else {
$(this).find(".footer_wrap").removeClass("topper");
}
};
$(window).scroll(scrollFn);
You don't need the
$(this).find
It is useless, try the following:
var targetOffset = $('#footer_wrap').offset().top,
$window = $(window);
$(window).on( 'scroll', function(){
if ( $window.scrollTop() >= targetOffset ) {
$("#footer_wrap").addClass("topper");
}else{
$("#footer_wrap").removeClass("topper");
}
});
And The CSS
#footer_wrap {
margin-top: 200px;
height: 130vmax;
background-color: #f4f4f4;
-ms-transition: all 300ms ease-in-out;
-webkit-transition: all 300ms ease-in-out;
-moz-transition: all 300ms ease-in-out;
-o-transition: all 300ms ease-in-out;
transition: all 300ms ease-in-out;
}
#footer_wrap.topper {
background-color: #000;
}
Then when #footer_wrap is at the top it will change the background.

jQuery scrollTop jumps to top of screen

When I load the page, the div is at the top of the screen, but when I start the scroll, it jumps to where it is supposed to be.
Check out the website here:
calretirement.com/classes-test.php
CSS:
.register{position:fixed !important; bottom:120px !important; width: 340.453px;
margin-top: 29px;
}
#stickyForm2015 {-webkit-transition: all 0.4s ease-in-out;
-moz-transition: all 0.4s ease-in-out;
transition: all 0.4s ease-in-out;
}
jQuery:
<script>
$(window).scroll(function(){
if
($(window).scrollTop() > 670){
$("#stickyForm2015").addClass("register");
}
else
{
$("#stickyForm2015").removeClass("register");
updateSliderMargin();
}
});
</script>
<script>
$(window).on("scroll", function(){
if
($(window).scrollTop() > 2500){
$("#stickyForm2015").removeClass("register");
updateSliderMargin();
}
});
</script>
Open to suggestions!! Need help!
If you want to animate scroll with jquery you can just do:
$('html, body').animate({scrollTop: '0'}, 400);
If you want to animate with css you need to animate from something to something, your classes don't appear to be doing that.
.original-class{
position: relative;
top: 500px;
transition: top .4s ease-in-out; //only necessary if you plan on animating back
}
.animate-original-class{
top: 0;
transition: top .4s ease-in-out;
}

jquery transit opacity animation conflict?

I have an element that I want to move and the, half way through the move, start fading out. By the time the move is complete, it has 0 opacity. I am using the transit library to make these animations smoother. Opacity on its own works. Move on its own works, but the 2 do not play nice together. where am i going wrong?
$(function() {
$("#go").click(
function(){
$("#block").transition({y:'90px', queue:false}, 2000);
$("#block").transition({ x: '90px',queue:false }, 2000 );
$("#block").transition({ opacity: 0 ,queue:false , delay:1000 }, 1000 );
});
});

I would consider using CSS transitions and just triggering them with jquery: JS Fiddle
CSS
div {
background-color:yellow;
width:100px;
border:1px solid blue;
position:absolute;
x:50px;
-webkit-transition: all .8s ease;
-moz-transition: all .8s ease;
-ms-transition: all .8s ease;
-o-transition: all .8s ease;
transition: all .8s ease;
margin-left: 0px;
}
JQuery
$("#go").click(function () {
$("#block").css('margin-left', '90px').css('opacity', '0');
});
JQuery (if you want the opacity to fade after it moves over): JS Fiddle
$("#go").click(function () {
$("#block").css('margin-left', '90px')
.delay(800)
.queue(function (next) {
$(this).css('opacity', '0');
next();
});
});
To actually use the transit plugin to solve this problem, you need to add them to the same transition() call.
$(function() {
$("#go").click(
function(){
$("#block").transition({ x: '90px', opacity: 0, queue:false }, 2000 );
//$("#block").transition({ opacity: 0 ,queue:false , delay:1000 }, 1000 );
});
});
