At my Page there are tow sections, a header div and the contents div. I want JS or jquery solution to stick the header section at the top, so that when user scrolls the contents section would cross and cover the header section.
html:
<div id="header">
<h3>I'd like to stick here at the background, please! </h3>
</div>
<div id="content">
<h3>I'd like to cross over the header when user scrolls.</h3>
</div>

Update: misunderstood, so you want the content to scroll over the header, not under. Then it should be like:
#header {
position: fixed;
height: 100px;
top: 0;
z-index: 100;
}
#content {
position: relative;
margin-top: 100px;
z-index: 101;
}
See an example here: http://jsfiddle.net/aorcsik/v7zav/
If your header is fixed height, say 100px, then:
#header {
position: fixed;
height: 100px;
top: 0;
}
#content {
margin-top: 100px;
}
This way when scrolled to the top, the header won't overlay the content, but when you start to scroll down, it will.
Something like this, if I understand your question:
<div id="content_wrapper" style="position:relative">
<div id="header" style="z-index:1; position:absolute; top:0px">
<h3>I'd like to stick here at the background, please! </h3>
</div>
<div id="content" style="z-index:5">
<h3>I'd like to cross over the header when user scrolls.</h3>
</div>
</div>
I'm using https://github.com/bigspotteddog/ScrollToFixed on my projects with no problems. ScrollToFixed allows you to set when the div will be fixed based on the scroll position.
fiddle with example: jsfiddle.net/ZczEt/167/
you should add css:
*{margin:0;padding:0}
#header{
position:fixed;
width:100%;
height:200px;
background:#ccc;
}
h3{
text-align:center;
}
#content{
background:#f1f1f1;
padding-top:200px;
min-height:500px;
}
jsfiddle
I myself came with another solution :
add another container div to the header and then position that div to fixed, and make the contents to be absolute. but this way you need to specify a min-height or height for the header:
http://jsfiddle.net/pna54/
<div id="header">
<div class="container">
<h3>I'd like to stick here at the background, please! </h3>
</div>
</div>
<div id="content">
<h3>I'd like to cross over the header when user scrolls.</h3>
</div>
css:
div{margin:0;padding:0}
h3{
padding:0;margin:0;
padding-top: 100px;
padding-bottom:100px;
text-align:center;
}
#header{
background:#ccc;
min-height:200px;
width:500px;
position:relative;
}
.container{
position:fixed;
width:100%;
max-width:500px;
}
#content{
background:#f1f1f1;
min-height: 500px;
position: absolute;
width:500px;
}

I am not good at English, so I ask questions using a translator.
I'm sorry.
I use the ScrollMagic library
Created a Mobile Page.
For ScrollMagic to work
html, body's height should be 100%.
Content Inside has an Iframe.
The Position property of the parent DIV of the Iframe is Fixed.
PC: Put your cursor over the iframe, scroll, scroll, and you won't scroll.
Mobile: Put your cursor on the Iframe and touchMove, you can't scroll.
If I scroll "iFrame,"
I want to scroll ".a, .b" instead.
Below is an example source
HTML
<div class="wrap">
<div class="content">
<div class="a">

</div>
<div class="b">

Setting the IFRAM's property to "pointer-events: none" will work.
But click should be possible in the IFRAM,
So I'm looking for another way.
If you have any good information, please let me know.
I have been reading about fixed div's within relative and absolute div's here:
Fix position of div with respect to another div
Fixed positioned div within a relative parent div
Fixed position but relative to container
And many other but none can help me to achive a behavior I have seen in few pages (blogs). I can not remember one at the moment, but here are some images to explain
View 1 & View 2
After scrolling down, the contextual menu sticks to the side of the view and moves down with the scrolling until reach the end of the section in which it stops. If there is more content after it, you can keep scrolling down but the contextual menu no longer follow your view. The same going up, you reach the section, the contextual menu follows you up until the start of the section, then stops and you can keep scrolling up.
Is this posible with only HTML and CSS or do I need a plugin?
Here is a jsFiddle piece of code, perphaps incomplete. Forgot to mention, I'm doing this in Angular 6+ as a component, so I don't have full access to the index.html file with the body tag. The jsFiddle shows what I can work with.
There were a few things going on:
You can set body { position: relative } in your CSS
position: sticky needs a full height column to work. Because your col-6 that was holding your menu was only as tall as it needed to be, it won't scroll.
I moved the p-sticky class to your column.
sticky also needs a top value to know where the element should stick to once it becomes sticky.
.p-sticky {
position: sticky;
top: 60px;
}
body {
position: relative;
}
/*some attemps*/
.p-relative {
position: relative;
}
.p-absolute {
position: absolute;
}
.p-sticky {
position: sticky;
top: 60px;
}
.p-fixed {
position: fixed;
}
/* Standar CSS*/
.navbar {
background-color: blue;
width: 100%;
}
.nav-fixed {
top: 0px;
z-index: 1;
position: fixed;
}
.content-ex1 {
height: 200px;
background-color: green;
}
.content-ex2 {
height: 500px;
background-color: #aaaaaa;
}
.menu {
height: 50px;
background-color: red;
}
<div class="navbar">
some navbar things
</div>
<div class="navbar nav-fixed">
some navbar things
</div>
<div class="content-ex1"> Some content here</div>
<div class="container">
<div class="row">
<div class="col-sm-6 p-sticky">
<div class="menu">menu or something</div>

<div class="col-sm-6 content-ex2"> Some content here</div>

<div class="content-ex1"> Some content here</div>
Here's the fiddle to play around with (which includes your bootstrap):

Note: you appear to be using an old version of BootStrap. You may want to update to the newest version. In that case, only a few things will change - namely, you move the p-sticky class to the menu.
Here's the newest version of BS 4.4: http://jsfiddle.net/kamr0bjw/

I'd like to build a website with a full height whatever the user's screen. Scroll is impossible, everything is shown in the page.
I tried something like :
<body>
<div class="header">
test
</div>
<div class="central">
test
</div>
<div class="footer">
test
</div>
</body>
html,body{
height:100%;
}
.header,.footer{
height: 20%;
background-color:blue;
}
.central{
min-height:60%;
background-color:red;
}
It works in my screen with a big resolution but not in my 15", page is scrollable. If body is limited to 100%, why all the elements aren't in the page?
JSFIDDLE
Thanks.
Because the body has built-in margin.
Just remove it.
A normal CSS Reset would generally have this as standard.
html,
body {
height: 100%;
margin: 0;
/* see? */
}
.header,
.footer {
height: 20%;
background-color: blue;
}
.central {
min-height: 60%;
background-color: red;
}
<body>
<div class="header">
test
</div>
<div class="central">
test
</div>
<div class="footer">
test
</div>
</body>
I think it's because the body has margins. Try :
html,body {
height:100%;
min-height:100%;
max-height:100%;
margin:0px;
padding:0px;
}
set min height to html tag and remove default margin, padding to body tag
html{
min-height:100%;
}
body{
padding: 0;
margin: 0;
min-height:100%;
width: 100%;
height: 100%;
}
I need to position header and footer accordingly to content height.
So the header and footer are adjacent to content, even when the content size change.
I would like to know if a CSS solution exists (even CSS 3), if no a JS solution.
Notes: I cannot change the order of DIV in the HTML.
Below pictures of the desired layout.
In more details:
I need the top side of the content positioned just after the end
bottom side of header.
I need the top side of the footer positioned just after the end
bottom side of content.
If header change height, content should move up/down.
If content change height, footer should move up/down.

Example is welcome :)
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html;charset=utf-8" />
<script>
</script>
<style>
#content-a, #content-b{
position: absolute;
width: 500px;
height: 250px;
}
#content-a {
background-color: red;
}
#content-b {
background-color: yellow;
}
#master {
position: absolute;
left: 60px;
z-index: 100;
}
#header, #footer {
width: 500px;
height: 50px;
}
#header {
background-color: gray;
}
#footer {
background-color: blue;
}
</style>
</head>
<body>
<div id="content-a">content a</div>
<div id="content-b" style="display:none">content a</div>
<div id="master">
<div id="header">header</div>
<div id="footer">footer</div>
</div>
</body>
</html>
with your html structure this isn't possible with pure css, especially with a dynamic height for the header and footer - as they are in a seperate div, it will be impossible for the content divs to know how much space is left to take up. You would need to use js to either move your divs and calculate the heights, but I would do something along the following:
body, html {
height:100%;
position:relative;
margin:0;
padding:0;
}
#master {
position:absolute;
top:0;
bottom:0;
left:0;
right:0;
}
#master > div {
display:table;
width:100%;
height:100%;
}
#master > div > div {
display:table-row;
width:100%;
}
and with the help of jquery, reorder your elements:
$('#master').wrapInner('<div/>');
$('#content-b').insertAfter($('#content-a').insertAfter($('#header')));
Example
Example with expanded content and header
Got it I think: http://jsfiddle.net/Preben/80a6q40x/1/
What I did:
Since all is in correct order except the header, we can do this:
Remove ALL position:absolute;
Put margin-top: 50px on the content-a
Put position:ansolute; top:0px; on the #header
You may also edit the #content-a to have min-height: 250px; to adjust to the content in height: http://jsfiddle.net/Preben/80a6q40x/4/
That's it.
<div id="content-a">content a</div>
<div id="content-b" style="display:none">content a</div>
<div id="master">
<div id="header">header</div>
<div id="footer">footer</div>
</div>
CSS:
#content-a, #content-b{
width: 500px;
height: 250px;
}
#content-a {
margin-top:50px;
background-color: red;
}
#content-b {
background-color: yellow;
}
#master {
z-index: 100;
}
#header, #footer {
width: 500px;
height: 50px;
}
#header {
background-color: gray;
position:absolute;
top:0px;
}
#footer {
background-color: blue;
}
what I'm trying to do is simple to tell. There is fixed div on my page on bottom. It must be always shown on bottom, so position fixed is used.
In this div there are 2divs, one small must be always on top of this fixed div, another must be scrollable.
The problem is small div, if I give him position fixed, it is position to top of window, not on top of this fixed div, as you can see in this fiddle
If small div is position absolute, it is on top of fixed div, but if it is scrolled, as you can see in this fiddle
HTML
<div class="bottom">
<div class="top"></div>
<div class="content"></div>
</div>
CSS
.bottom
{
padding:20px;
height: 253px;
position: fixed;
bottom:0px;
width:100%;
background-color: red;
overflow-x: hidden;
overflow-y: scroll;
}
.top
{
height:50px;
width:100%;
background-color: yellow;
position: fixed;
top: 0px;
}
.content
{
height: 1500px;
background: linear-gradient(green, blue);
}
Is is possible to make this work without watching scrolling by jvascript? By pure CSS?
You can use a wrapper <div> for the content and let it scroll - so that the absolutely positioned sibling does not scroll along with it, as follows:
HTML
<div class="bottom">
<div class="top"></div>
<div class='contentWrap'>
<div class="content"></div>
</div>
</div>
CSS
.contentWrap{
height:100%;
overflow-y:auto;
}
* {
margin: 0;
padding: 0;
}
.bottom {
padding: 20px;
height: 253px;
position: fixed;
bottom: 0px;
width: 100%;
background-color: red;
overflow: hidden;
}
.top {
height: 50px;
width: 100%;
background-color: yellow;
position: absolute;
top: 0px;
}
.contentWrap {
height: 100%;
padding-top: 30px; /* .top height - .bottom padding*/
overflow-y: auto;
}
.content {
height: 1500px;
background: linear-gradient(green, blue);
}
<div class="bottom">
<div class="top"></div>
<div class='contentWrap'>
<div class="content"></div>
</div>
</div>
JSFiddle Demo
Your approach using fixed -> absolute is absolutely correct since you can position an element absolute but relative to its parent by doing so. The problem is that the absolute .top always appears on top of .bottom - so if .bottom is scrolled, .top will follow.
My solution would be using position:fixed; on .top, but using bottom instead of top:
.top {
....
position:fixed;
bottom:253px; /*note sure how it should look at the end, try it yourself*/
}
Add div with class top inside div with class content and remove top:0 from .top class:
html
<div class="bottom">
<div class="content" >
<div class="top"></div>
</div>
<div>
css
.top
{
height:50px;
width:100%;
background-color: yellow;
position: fixed;
}
fiddle
Try this, it basically just puts a frame container around your scrollable div to keep everything in place. JSFiddle
<div class="bottom">
<div class="top"></div>
<div class="scroll-container">
<div class="content" ></div>
</div>
<div>
.scroll-container
{
height: 203px;
overflow-y: scroll;
}
Also, remove overflow-y: scroll; from the .bottom class
If you already dealing with fixed heights & positions, why not just position the 'top' section as fixed as well? check the Fiddle Demo
like so:
.top
{
height:50px;
bottom:243px;
width:100%;
background-color: yellow;
position: fixed;
}
