I can't for the life of my figure this out. Does anyone know how this scrolling effect is created on this website? - http://blindbarber.com/news
I'm working on a project where this effect would greatly help so that my fixed navigation isn't too large when scrolling.
Thanks in advance.
The header stays on top with the css position:fixed .. either you can set the header css -- position:fixed right from the start or change it to position:fixed once he starts scrolling the page.. and update the header to the contents you want to keep as he scrolls..
// css
.container {
height: 2000px;
width: 100%;
background-color: yellow;
}
.header {
text-align: center;
background-color: red;
height: 100px;
min-height: 50px;
width: 100%;
}
// js
window.onscroll= function () {
var top = window.pageXOffset ? window.pageXOffset : document.documentElement.scrollTop ? document.documentElement.scrollTop : document.body.scrollTop;
var header = document.getElementById("header");
if (top > 50){
header.style.position = "fixed";
header.style.height = "50px";
} else {
header.style.position = "relative";
header.style.height = "100px";
}
}
//html
<div class="container">
<div id="header" class="header">
Hello World
</div>
</div>

This is what your looking for I think:
http://www.backslash.gr/content/blog/webdevelopment/6-navigation-menu-that-stays-on-top-with-jquery
So the google search terms that gives you an answer is "responsive menu" + javascript.
In my case I was looking for a jquery plugin so I added in "jquery". I didn't find much using "fixed header transformation"
:)

First of all, I can only use vanilla javascript for the current project.
Run my codes below, there are 3 sections, I want to fix the second black section when it reached the top of the screen, but now the issue is if you use mouse wheel or touchpad scroll down the page, you will see the page is shaking.
I tried many ideas but can't fix this issue, hope anyone can give a solution or correct direction. Thanks!
window.addEventListener('wheel', function(e) {
var nextSection = document.querySelector('#next-section');
var fixedSection = document.querySelector('#fixed-section');
var doc = document.documentElement;
//When scroll down
if (doc.scrollTop >= nextSection.offsetTop - window.innerHeight) {
doc.scrollTop = nextSection.offsetTop - window.innerHeight;
}
});
.section {
width: 100%;
height: 400px;
line-height: 400px;
background: #ccc;
text-align: center;
padding-top: 20px;
}
#fixed-section {
background: #000;
color: #fff;
}
<div id="previous-section" class="section">Just scroll down</div>
<div id="fixed-section" class="section">Fix this section when it reached the top of the viewport.</div>
<div id="next-section" class="section"></div>
How can I make my text appear when scrolling? I've found this http://www.jqueryrain.com/?HZtLD8hN but I'd like to know how it works. There was a similar question asked but I don't understand it. Can someone explain, or provide examples, how to make this work?
Thanks
HTML
<div id = "divToShowHide" class = "BeforeScroll">Content i want to appear while scrolling</div>
CSS
.BeforeScroll {
width: 100%;
height: 200px;
background-color: yellow;
}
.AfterScroll {
width: 100%;
height: 200px;
background-color: red;
}
A basic example is this: say some of your content is in a<div id="appearble_text"> that is at 70% of the total height of the page. <div id="container">
Initially you will set document.getElementById("appearable_text").style.display = "none";
You can set up a function
function OnScroll() {
var totalHeight = this.offsetHeight; //(this, because container is the caller of the function from the code below)
if (this.scrollTop || this.scrollTop > totalHeight * 0.7) { //if scrolling reached 70% of height
document.getElementById("appearable_text").style.display = "block";
}
}
and then use it
var container = document.getElementById("container");
container.onscroll = OnScroll;
Of course, instead of just suddenly displaying the <div> you can fade it in or do all sorts of CSS/JQuery tricks you like.
I have a header, in which i put my h1 and h2 headings at top. The problem is that header scrolls along the scroll bar which is of course normal but i want to fixed it at some point when all the headings on header scroll away. At this point I want header to stop and stays fixed.
I already tried fixed position but of course it fixed heading as well which exactly I don't want.
I also tried this JavaScript but no luck.
JavaScript
$(window).scroll(function() {
var _height = 120 - (120 * $(this).scrollTop() / $('body').height());
if (_height >= 80) {
$('.header_container').height(_height);
}
});
and here qre my HTML and CSS codes respectively.
HTML
<div class="header_container" id="header_container">
<div id="header_titles">
<h1 class="homepage-heading">Browse</h1>
<h2 class="homepage-heading-subtle">GENRES & MOODS</h2>
</div>
</div>
CSS
#header_container {
background-color: black;
width: 100%;
height: 120px;
top: 0;
left: 0;
right: 0;
}
#header_titles {
position: absolute;
width: 100%;
font-size: 35px;
text-align: center;
padding-top: 10px;
}
So, let me see if I get this...you want your header to be scrolled normally with the page until a certain point where it becomes fixed?
EDIT
Ok, well, you could determine the element on the page that you want the position to be triggered at. Like, the top of a certain paragraph, and use that position in your condition.
var condition = $(element).offset().top;
if($(window).scrollTop > condition) { //add a fixedClassName } else { remove the fixedClassName }
and have header.fixedClassName have those proprieties ( with position fix, top 0 and width: 100% to your header etc). Be sure to add and remove a class on the body that gives it padding-top with the height of your displaced header.
Used some similar effect here http://goodmen.se/ after a point the logo shows up in the header, then there's a background change. You do something similar with your position.
EDIT 2
Here's an example fiddle http://jsfiddle.net/Corsico/vpskd8hd/
So you want a sticky header?
In your javascript create a code:
var $header_container = $('#header_container');
var header_height = $header_container.outerHeight(true);
if($(window).scrollTop() < header_height){
$header_container.removeClass('sticky');
} else{
$header_container.addClass('sticky');
}
$(window).on('scroll', function(){
if($(window).scrollTop()< header_height){
$header_container.removeClass('sticky');
} else{
$header_container.addClass('sticky');
}
});
This will add a sticky class to your header, and then you can set the header to be fixed:
.sticky{
position:fixed;
top:0;
left:0;
width:100%;
display:block;
}
This should do it. When you scroll pass the height of the header, you'll get the 'sticky' class, if not, you'll remove the sticky class...
This is a question that once asked in a different variation,
and i tried to use the code, but it doesn't work for me.
I want my footer to animate up when scrolling just a bit before reaching the bottom, and closing while scrolling up.
like in this site - you will see if you scroll all the way down.
http://www.pronto.co.il
this is my code:
css:
body, html { height: 1000px; }
html:
<button id="buttonTest">try me</button>
<div id="footer" style="display: none;"><img src="pics/try_me_1.png" ></div>
I'm trying to leave the jquery code but I don't understand exactly how it works here yet.
so this is the link to the answer - i took it and use animate() instead the alert.
Footer animates up when you reach bottom of screen, but fails to animate down when you scroll back up
will help me a lot. thank u so very much
you can add/remove a given class
var footer = document.querySelector("#footer");
window.onscroll = function(event) {
((window.innerHeight + window.scrollY) >= document.body.offsetHeight) ? footer.classList.add("visible") : footer.classList.remove("visible")
};
And here is your css
#footer{
position: fixed;
bottom: 0;
overflow: hidden;
height: 0;
transition: height .3s ease
}
#footer.visible{
height: 100px;/*what ever you want*/
}
As the comment suggest there is no animation on the link you provide, but based on the link question is just simple as this:
var isShowing = false;
$(window).scroll(function() {
if ($(window).scrollTop() + $(window).height() === $(document).height()) {
$('#footer').slideToggle();
isShowing = true;
} else if (isShowing === true && $(window).scrollTop() + $(window).height() <= $(document).height() * 0.9) {
$('#footer').slideToggle();
isShowing = false;
}
});
body,
html {
height: 1000px;
}
#footer {
height: 150px;
position: fixed;
bottom: 0;
width: 100%;
left: 0;
background:black;
display:none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<button id="buttonTest">try me</button>
<div id="footer"></div>
Im trying to add a footer at the bottom of this content that doesn't overlay the content but moves it up.
The only way I can see it working would be something like, when browser is at the bottom remove 'fixed' class on the left red '#work'.
js fiddle DEMO
Updated js fiddle DEMO
HTML
<div id="header-block">
Header-block, this sits here in the background
</div>
<div id="content">
<div id="work">
This content should be fixed when at the top
</div>
<div id="description">
This content should scroll -
</div>
</div><!-- end content -->
<div id="footer">
This should appear at the bottom
</div>
CSS
body {
margin: 0px;
padding: 0px;
}
#header-block {
background: green;
width: 100%;
position: fixed;
z-index: 1;
height: 300px;
top: 0;
}
#content {
margin-top: 300px;
width: 100%;
position: relative;
z-index: 2;
}
#work {
background: red;
width: 50%;
height: 100vh;
float: left;
position: absolute;
}
#description {
background: blue;
width: 50%;
height: 1200px;
float: right;
font-size: 30px;
}
#footer {
background: black;
width: 100%;
height: 100px;
position: absolute;
z-index: 3;
bottom: 0;
}
If I understand your question correct, this should do the trick (although it depends very much on JavaScript unfortunately).
// Fix work column on scroll
contentStart = $("#content").offset().top ;
contentSize = $("#content").height() ;
window.onscroll = function(){
if( window.XMLHttpRequest ) {
var position=window.pageYOffset;
// calculate the position of the footer and the actual seen window
var docViewTop = $(window).scrollTop();
var docViewBottom = docViewTop + $(window).height();
var elemTop = $("#footer").offset().top;
if ( position > 300 && !(docViewBottom >= elemTop)) {
$('#work').css({'position':'fixed', 'top':'0', 'height':'100vh'});
} else {
// if the footer is visible on the screen
if(docViewBottom >= elemTop) {
$('#work').css({ 'top': 0 - (docViewBottom - elemTop) }); // scroll the #main div relative to the footer
} else {
$('#work').css({'position':'relative', 'top': 'auto'}) ;
}
}
}
}
For further informations about the calculations, perhaps this question on stackoverflow is useful.
Edit: Andrew Haining posted his answer in between of my answer, perhaps give his link a try and maybe it's a better (more proper) solution. Unfortunately I haven't actualised this page when I was testing your code in JSFiddle and I didn't see his answer.
If you want to use my script, make sure you can test it with different resolutions. It works just fine for my resolution in JSFiddle, I didn't test any other.
I'm not 100% sure what you want, but if you remove the position: absolute and the bottom: 0 from the footer, and put a div with class='clearboth' above the footer, it seems to do what you need.
CSS
.clearboth {
clear: both;
}
This is a drawing of what I see on your fiddle;
Do you want the red and the blue to always be touching the black?
I don't see the red overlying the black
You should use jQuery to add a class containing the position:fixed value when the scroll position of the page is less than the inline position of the #work div. Once it scrolls past the position, remove the class and have the element fall back in line.
You can achieve this using the following jQuery methods.. .scrollTop() .offset().top() and $(window).height().
This tutorial will give you an understanding of what you need to do to achieve the necessary results, you will just have to change the calculation slightly using $(window).height(), $('#footer').height() and a few other changes to get what you desire.
Based on the question you asked i think this is what you mean. The red div should be fixed when it gets to the top but be absolute when it is below the top for scrolling and the black footer should be below the red while scrolling, check this code i have done for you. just add this jquery script and run it.
<script type="text/javascript" src="js/jquery.js"></script>
<script>
$(document).ready(function() {
$(window).scroll(function () {
console.log($(window).scrollTop());
if ($(window).scrollTop() >= 322) {
$('#footer').css("z-index","1");
$('#work').css(
{
"background": "red",
"width": '50%',
'height': '100vh',
'float': 'left',
'position': 'fixed',
'top': '0'
});
}
if ($(window).scrollTop() <= 322)
{
$('#work').css(
{
"background": "red",
"width": "50%",
"height": "100vh",
"float": "left",
"position": "absolute"
});
};
});
});
</script>
If not exactly a parallax, this is somewhat close to how parallax works, containers moving at different speeds, and some containers sitting fixed or scrolling when they attain a particular top/bottom offset in the viewport.
There's plugin that can do it. Skrollr
You can use Skrollr along with skrollrcss, and it'll make sure how the containers take position on screen based on scrolltop of the window and the container specifically.
