On my website, I want to use a kind of parallax effect. But normally you only fix a background picture to the screen and so allow the scrolling 'over' it, what I want is kind of the same thing with all of my content.
The website is a one-page side with several sections. Ea h of the sections has a min-height of 100vh on landscape screens. If say section 1, is in the viewport, the user should scroll normally, until the very bottom of the section reaches the bottom of the screen. At the moment of which the next container enters the viewport, section 1 should be fixed, so that section 2 slides over section 1 like a sheet of paper and covers first the content of the bottom.
Have you any idea on how to do this? I don't need fully coded examples, just some ideas on how you would do this.
Thanks in advance.
Some more details
I think that my explanation of what I'm trying to get is a bit vague, so I'm going to extend this a bit.
Imagine you have 5 sheets of paper, on every sheet, there is some content, let's say an About section, on another sheet some Features and so on. Now every sheet has a height of your viewport, so all that you see is that sheet of paper. If the content is bigger than your viewport, the sheet gets bigger too. This is quite obvious I think. If you scroll down the page, the sheet of paper, you're seeing should scroll up until its end matches with the viewport border. Now instead of moving up when scrolling this sheet of paper stays at that exact place. The new content on sheet 2 slides over it, like a new layer.
Perhaps you mean something like this?
<main>
<section class="orange fixed">
<h2>
Some text
</h2>
</section>
<section class="blue">
<h2>
Some text
</h2>
</section>
<section class="orange">
<h2>
Some text
</h2>
</section>
</main>
JS:
var $sections = $('main section');
var sectionHeight = $sections.eq(0).outerHeight();
var setCurrent = function(position ) {
$sections.eq(position).addClass('fixed').siblings().removeClass('fixed');
}
$(window).on('scroll', function() {
var scTop = $(window).scrollTop();
var position = Math.ceil( scTop / sectionHeight );
setCurrent( position - 1 );
})
And some sass
body {
margin: 0;
}
main {
padding: 0;
padding-top: 100vh; // this is the trick
section {
height: 100vh;
text-align: center;
color: white;
padding-top: 200px;
position: relative;
margin: 0;
h2 {
margin: 0;
padding: 0;
}
&.orange {
background: orange;
}
&.blue {
background: blue;
}
&.fixed { // this is the trick
position: fixed;
left: 0;
top: 0;
width: 100%;
}
}
}

So I wanted to make a page like https://www.guillaumetomasi.com/ .How can I hide the scrollbar and make a custom one like that in the page.
With CSS attributes like overflow-x: hidden and overflow-y: hidden you can hide scrollbars.
The custom scrollbar and the scrolling proccess is controlled by Javascript via and events.
The thing is simple and that's, they are not using any scrolling at all, but what you feel is a modified scroll for those slides is actually a slideshow built by JavaScript functionalities. These side slideshow are nowadays in trend and gives you a feel of pseudo scroll. It will be better if you would ask how to achieve that slideshow in a web page instead of that scrolling...
The scroll bar can be hidden with css ::-webkit-scrollbar {width: 0px;}
The custom scroll bar is made with javascript. Here's an example of how it could be done:
window.addEventListener("scroll", function() {
var section1 = document.getElementById("section1");
var section2 = document.getElementById("section2");
var section3 = document.getElementById("section3");
var indicator = document.getElementById("scroll-indicator");
if (window.scrollY < section2.offsetTop ) { // If scroll height is above section 2
indicator.innerText = "1"
}
if (window.scrollY > (section1.offsetTop + section1.offsetHeight)) { // If scrolled past section 1
indicator.innerText = "2"
}
if (window.scrollY > (section2.offsetTop + section2.offsetHeight)) {// If scrolled past section 2
indicator.innerText = "3"
}
});
p {
position: fixed;
right: 15%;
top: 50%;
color: black;
font-size: 24px;
font-family: arial;
}
::-webkit-scrollbar {
width: 0px; /*This removes the scroll bar*/
}
<div id="section1" style="height: 500px; background-color: lightblue">Scroll Down</div>
<div id="section2" style="height: 500px; background-color: pink">Keep scrolling</div>
<div id="section3" style="height: 500px; background-color: Khaki">Almost there</div>
<p id="scroll-indicator">1</p>
Any ideas how to fix this problem: On a page with TOC (table of contents) with links pointing to hashtags within the same page, when the browser scrolls down other fixed position elements hide it. The browser should scroll further down to avoid being hidden by the fixed elements.
Fiddle to demonstrate this problem: https://jsfiddle.net/fcro6mth/ Click Section One or Section Two - the browser scrolls down to it but its hidden by the fixed header
Solution with JS: https://jsfiddle.net/fcro6mth/1/
Can you think of any solution that doesn’t involve JS?
Code from JS fiddle:
HTML:
<header>
This is the fixed position header
<nav>
Section One
Section Two
Section Three
</nav>
</header>
<div class="body">
This is the body.
<section id="section1">This is section one</section>
<section id="section2">This is section two</section>
<section id="section3">This is section three</section>
</div>
CSS:
section {
background: lightgrey;
margin: 20px 0;
padding: 20px 10px;
height: 300px;
}
header {
background-color: grey;
position: fixed;
top: 0;
padding: 10px;
width: 100%;
box-sizing: border-box;
left: 0;
color: white;
}
.body {
margin: 70px 10px 0 10px;
}
JavaScript:
$("nav a").click(function (event) {
var $target = $(event.currentTarget),
$scrollToTarget = $($target.attr("href")),
$header = $("header"),
prop = {
scrollTop: $scrollToTarget.offset().top - $header.outerHeight(true)
},
speed = 1000;
$('html, body').animate(prop, speed);
});

Nice example to make hidden anchors for offsetting your sections.

Solution
I wrapped your sections in div-wrappers gave them the IDs, padded them down and pulled them back up with a negative margin.
This results in the exact same appearance, but the links do what you want them to do.
Example:
HTML:
<div id="section1" class="wrapper">
<section >This is section one</section>
</div>
CSS:
.wrapper {
padding-top: 50px;
margin-top: -50px;
}
I have struggled with this issue a lot in designing a webpage with a combined banner / navbar of about 300px fixed at the top of a page full of short items linked to by anchor links from the website's home page.
The problem I have found with the "margin-top: -XXpx; padding-top: XXpx" approach is that the invisible padding overlaid the preceding item, meaning that active content (ie. links) were blocked. I overcame this by applying positioning to the anchored elements and setting the z-index so that the first item was on top of the stack with each subsequent item lower in the stack - like this:
CSS
.anchored-element {
padding-top: 300px;
margin-top: -300px;
position: relative;
}
HTML
<div class="anchored-element" style="z-index: 99">FIRST ITEM</div>
<div class="anchored-element" style="z-index: 98">SECOND ITEM</div>
<div class="anchored-element" style="z-index: 97">THIRD ITEM</div>
... etc
This provided a fix that worked for me across Firefox, Safari and Chrome on my desktop, and on my iOS devices. I hope this helps others tackle this very frustrating issue in bootstrap!
I have two navigation in my website. Both the navigation bars are fixed. Basically when I scroll up, I would like to use the animate() and show both the navigation bar in the page. How do I get the scroll up event and use that to animate the divs, like the Google search widget. I would really appreciate your help. Thank you.
html:
<div id="navbar_header">
some link
</div>
<div id="main_content">
<p>Some content...</p>
</div>
<div id="navbar_footer">
some link
</div>
css:
#navbar_header {
background: #22313F;
position: fixed;
top: 0px;
left: 0px;
width: 100%;
height: 40px;
}
#navbar_footer {
background: #22313F;
position: fixed;
bottom: 0px;
left: 0px;
width: 100%;
height: 40px;
}
Normally using the window for the scroll event should be sufficient, as it's big enough and the one element, that's being scrolled. If jQuery is loaded correctly, you could try something like this:
$(document).ready(function(){
var lastTopPosition = 0;
$(window).scroll(function(){
var topPosition = $(window).scrollTop();
if (topPosition > lastTopPosition ){
$("#navbar_header").stop(true).animate({'top':'-40px'}, 200);
$("#navbar_footer").stop(true).animate({'bottom':'-40px'}, 200);
} else {
$("#navbar_header").stop(true).animate({'top':'0px'}, 200);
$("#navbar_footer").stop(true).animate({'bottom':'0px'}, 200);
}
lastTopPosition = topPosition;
}
});
This piece of code gets the current position from the top everytime you scroll. If the distance gets bigger (scroll down) the two bars fadeout. If it's getting smaller (scroll up) it fades in. You can replace the FadeOut/In methods here with you animate() call too. A check, if the elements are displayed would be good here too, but I guess you can figure that one out ;-)
If I understood this right, something along the lines of:
$("#main_content").scroll(function(){
$('#navbar_header').show(300);
$('#navbar_footer').show(300);
});
Where show(300) will basically do a 300ms showing animation of your divs.
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...
I'm trying to replicate the effect on this website in the portfolio section where it slides a panel in the full size of the viewport and then slides it out when you click close.
Example here: http://alwayscreative.net/#portfolio
Here's my current markup:
<section class="panel" id="portfolio">
<section class="content">
<h1>What are you <strong>interested</strong> in?</h1>
<a class="btn-portfolio" id="btn-commercial" href="#">Commercial</a>
<a class="btn-portfolio" id="btn-residential" href="#">Residential</a>
</section>
</section>
The .panel section is 100% height and width of the viewport and I'd like 2 different panels to be able to slide in — one for #btn-commercial and one for #btn-residential.
Any ideas how to make this happen?
If it helps any, here's my site so far: http://www.freshbrand.ca/testlink/top40/#portfolio
Here's how you would do it with JQuery but clearly you can do it in normal javascript if you prefer. Set up the panels with position absolute in your css:
.panel {
position: absolute;
top: 0;
height: 100%;
border-width: 0;
margin: 0;
}
.panel inactive{
display: none;
}
.panel active {
display: block;
left: 0;
width: 100%;
height: 100%;
}
in your javascript (after the dom has loaded) get the screen dimensions and set the positions of the inactive elements to just off the right hand edge of the screen:
$('.panel').css('width', screen.innerWidth);
var setup = function() {
$('.portfolio-panel.inactive').css('left', window.innerWidth);
$('.portfolio-panel.active').css('left', 0);
}
setup();
When you wish to slide a panel in from the right, pass its id to the following function:
var slideIn = function(panelId) {
$('#' + panelId).animate({
left: 0
}, 400, function () { // animates the #left property from the screen width down to zero (i.e. slide it in from the right hand edge of the screen)
// tidy up
$('.portfolio-panel.active').removeClass('active').addClass('inactive');
$('#'+panelId).removeClass('inactive').addClass('active');
setup();
});
};
EDIT: The event handler would look something like this:
$('.btn-portfolio').click(function() {
slideIn($(this).attr('id').substr(4)); // extract the panel name from the id and pass it into slideIn
});
The only remaining issue is to eliminate the horizontal scroll bar you will probably see during the animation. Just add overflow-x: hidden; to the element to which the scroll bar belongs (probably body, but it depends on how you've structured and styled the rest of your site)
This is basically a single page website, a lot of jQuery plugins are available for the same.
