Here is my tricky problem. I'm trying to do this:
http://www.hostingpics.net/viewer.php?id=767312test.gif
(More clear than an explication I think).
My structure :
<header></header>
<div class="section">
<div class="text"></div>
<div class="content"></div>
<div class="img"><img src="img1.png"/></div>
</div>
<div class="section">
<div class="text"></div>
<div class="content"></div>
<div class="img"><img src="img2.png"/></div>
</div>
<div class="section">
<div class="text"></div>
<div class="content"></div>
<div class="img"><img src="img3.png"/></div>
</div>
<footer></footer>
Important informations :
"Header" is fix
"Content" fit to the screen less the height of header
Every "section" are the same but with different content
When the image comes to an end, the "content" div is unfixed.
I am using "section" for implementing a next and previous button in the header (with anchors).
My problem is the scrolling part. I am really lost when I try to fix the "content" div. I don't know how to fix everything except the scroll of the image in the active "img" div when the active "content" div hits the header. (Everyone follows? Look here : http://www.hostingpics.net/viewer.php?id=767312test.gif
For the scrolling part in the "img" div, I was thinking use a sort of "overflow:scroll" but the scrollbar is really awful.
I don't know if it's enough clear. If there is any problem I can complete my problem. I am not very comfortable with complex structures in html with JS.
Thanks for your help!
This is pretty close to what you're asking for (using CSS only).
This relies on the fact that the backgrounds are solid colors. It uses various specifically-defined height properties as well that match some padding properties.
The .top-bar and .bottom-bar elements can probably be changed to pseudo elements if you don't want the extra HTML.
HTML:
<header>Header</header>
<div class="top-bar"></div>
<div class="bottom-bar"></div>
<div class="section">
<div class="text">Section 1 Text</div>
<div class="content">
<div class="img"><img src="http://placekitten.com/100/1000"/></div>
</div>
</div>
<div class="section">
<div class="text">Section 2 Text</div>
<div class="content">
<div class="img"><img src="http://placekitten.com/200/2000"/></div>
</div>
</div>
<div class="section">
<div class="text">Section 3 Text</div>
<div class="content">
<div class="img"><img src="http://placekitten.com/300/3000"/></div>
</div>
</div>
<footer>Footer</footer>
CSS:
body {
margin: 0;
padding: 100px 0 0;
}
header {
background-color: red;
height: 100px;
position: fixed;
top: 0;
width: 100%;
z-index: 10;
}
footer {
background-color: blue;
height: 100px;
}
.section {
min-height: 400px;
}
.text {
background-color: aqua;
height: 50px;
}
.content {
background-color: green;
min-height: 100%;
padding: 40px 0;
position: relative;
}
.img {
background-color: yellow;
min-height: 70%;
margin: 0 auto;
padding: 40px 0;
text-align: center;
width: 80%;
}
.img > img {
vertical-align: middle;
}
.top-bar, .bottom-bar {
background-color: green;
height: 40px;
position: fixed;
width: 100%;
z-index: 5;
}
.top-bar {
top: 100px;
}
.bottom-bar {
bottom: 0;
}
footer, .text {
position: relative;
z-index: 6;
}
JSFiddle here.
For an almost completely correct solution, here is one with some jQuery involved.
New CSS:
body {
margin: 0;
padding: 100px 0 0;
}
header {
background-color: red;
height: 100px;
position: fixed;
top: 0;
width: 100%;
z-index: 10;
}
footer {
background-color: blue;
height: 100px;
}
.section {
min-height: 400px;
}
.text {
background-color: aqua;
height: 50px;
}
.content {
background-color: green;
min-height: 100%;
padding: 40px 0;
position: relative;
}
.img {
background-color: yellow;
min-height: 70%;
margin: 0 auto;
padding: 40px 0;
text-align: center;
width: 80%;
}
.img > img {
vertical-align: middle;
}
.top-bar, .bottom-bar {
background-color: green;
height: 40px;
position: fixed;
width: 100%;
}
.top-bar {
top: 100px;
z-index: 5;
}
.bottom-bar {
bottom: 0;
z-index: 7;
}
footer, .text {
position: relative;
z-index: 8;
}
.img-fix {
bottom: 40px;
height: 400px;
overflow: hidden;
position: absolute;
width: 100%;
z-index: 6;
}
jQuery:
$(document).ready(function(){
$(".content").each(function(){
$(this).append($(this).html());
$(this).find(".img + .img").wrap("<div class='img-fix'></div>");
});
$(window).resize(function() {
resizeImgFix();
});
resizeImgFix();
});
function resizeImgFix() {
$(".img-fix").height($(window).height() - $("header").height() - $(".top-bar").height() - $(".bottom-bar").height());
$(".img-fix").each(function(){
$(this).scrollTop($(this).prop("scrollHeight"));
});
}
JSFiddle here.
Note: It duplicates the .img element and its children. This could be memory intensive depending. However, it does make it work as intended without any visual lag or artifacts.

I'm trying to position a "seeker" in a div element that has other elements in it. I want the seeker to be able to move on top of the content div, without pushing other content around, while also following the scrollbar. The area is resizable so I can't use constant width/height. Like the seeker in a video editor would.
This is what I've gotten so far
#container {
width: 200px;
height:100px;
background-color: gray;
overflow: scroll;
}
#content {
width: 300px;
height: 120px;
}
#box {
width: 40px;
height: 40px;
background-color: green;
}
#seekerContainer {
position: relative;
width: 100%;
height: 100%;
}
#seeker {
width: 4px;
height: 100%;
position: relative;
background-color: blue;
left: 10%;
}
<div id="container">
<div id="content">
<div id="seekerContainer">
<div id="seeker"></div>
</div>
<div id="box"></div>
</div>
</div>
And I've tried different combinations having the seekerContainer and seeker be position absolute/relative, but either the seeker wont follow the scrolling, or it extends the height of the div.
Any pointers to fix this?
I think this is what you are looking for:
.container {
width: 200px;
height: 100px;
background-color: gray;
overflow: scroll;
}
.content {
height: 500px;
position: relative;
}
.box {
width: 40px;
height: 40px;
background-color: green;
}
.seeker {
width: 4px;
height: 100%;
position: absolute;
background-color: blue;
left: 10%;
top: 0;
}
<div class="container">
<div class="content">
<div class="seeker"></div>
<div class="box"></div>
<div class="box"></div>
<div class="box"></div>
<div class="box"></div>
</div>
</div>
Also, you don't want to put id on every element and use id for styling. You should use classes for that. ID of the element has to be unique for the page so it's not very useful when you need to apply the same styling to more elements.
I have a container with two columns, one of which holds a sidebar.
JSFiddle
The sidebar is fixed, and when it gets near the bottom I used jQuery to alter the bottom to have it roughly stay at the bottom of the container.
How can I make it so it stops moving perfectly when it hits the bottom of the container (outlined in red)? It would have to work for a sidebar of any height.
HTML
<div class="container">
<div class="col-left">
<div class="sidebar">
fixed sidebar
</div>
</div>
<div class="col-right">
<p>Paragraph</p>
<p>Paragraph</p>
<p>Paragraph</p>
</div>
</div>
<footer>Footer</footer>
CSS
.container {
outline: 1px solid red;
position: relative;
}
.col-left {
width: 58%;
display: inline-block;
outline: 1px solid black;
vertical-align: top;
height: 100%;
}
.col-right {
width: 40%;
display: inline-block;
outline: 1px solid black;
vertical-align: top;
}
.sidebar {
position: fixed;
top: 50px;
left: 50px;
height: 200px;
width: 100px;
background: #fff;
}
footer {
background: #000;
width: 100%;
height: 300px;
margin-top: 100px;
color: #fff;
}
jQuery (Doubt it'll be of use I think it needs to be rethought)
jQuery(window).scroll(function(){
var scrollBottom = jQuery(document).height() - jQuery(this).scrollTop() - jQuery(this).height();
console.log(scrollBottom);
if (scrollBottom < 300){
jQuery('.sidebar').css('bottom', Math.abs(scrollBottom - 420));
jQuery('.sidebar').css('top', 'auto');
} else {
jQuery('.sidebar').css('bottom', 'auto');
jQuery('.sidebar').css('top', '50px');
}
Here's a jQuery solution whipped up by calculating heights of the relevant elements, and factoring in the current scroll position of the page. When the sidebar would normally move outside of its container, a .lock class is added to it that unfixes it with CSS.
Working example below:
var $sidebar = $('.sidebar');
var $container = $('.container');
var sideBottom = $sidebar.offset().top + $sidebar.height();
var contBottom = $container.offset().top + $container.height();
$(window).scroll(function() {
if (window.scrollY + sideBottom > contBottom) {
$sidebar.addClass('lock');
} else if ($sidebar.hasClass('lock')) {
$sidebar.removeClass('lock');
}
});
body {
background: #eee;
margin: 0;
}
.container {
outline: 1px solid red;
position: relative;
}
.col-left {
width: 58%;
display: inline-block;
outline: 1px solid black;
vertical-align: top;
height: 100%;
}
.col-right {
width: 40%;
display: inline-block;
outline: 1px solid black;
vertical-align: top;
}
.sidebar {
position: fixed;
top: 50px;
left: 50px;
height: 140px;
width: 100px;
background: #fff;
}
.sidebar.lock {
position: absolute;
bottom: 0;
top: auto;
}
footer {
background: #000;
width: 100%;
height: 400px;
margin-top: 100px;
color: #fff;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="container">
<div class="col-left">
<div class="sidebar">
fixed sidebar
</div>
</div>
<div class="col-right">
<p>Paragraph</p>
<p>Paragraph</p>
<p>Paragraph</p>

I am trying to have a vertical line for a news feed and i am looking for a solution to make its height equal to the screen when scrollbar reach bottom of the screen dynamically as items in the news feed will be loaded dynamically on scroll.
I tried using 100vh and 100% but then height is fixed to the height of the viewport.
Here is the div :
<div class="verticalLineFeed">
</div>
CSS for the div :
.verticalLineFeed {
width: 2px;
height: 100%;
border-left: 5px solid #cdcdcd;
position: absolute;
margin-left: 32px;
margin-top: 65px;
}
Any idea for doing this in css3 or jquery will be helpful
Code Snippet :
.verticalLineFeed {
width: 2px;
height: 100%;
border-left: 5px solid #cdcdcd;
position: absolute;
margin-left: 32px;
}
.main {
width: 100%;
height: 2000px;
}
<div class="verticalLineFeed">
</div>
<div class="main">
</div>
Use a wrapper and set it to position: relative
.wrapper {
position: relative;
}
.verticalLineFeed {
width: 2px;
height: 100%;
border-left: 5px solid #cdcdcd;
position: absolute;
margin-left: 32px;
}
.main {
width: 100%;
height: 2000px;
}
<div class="wrapper">
<div class="verticalLineFeed">
</div>
<div class="main">
</div>
</div>
Or set position: relative to the body (haven't tested this on all browsers though)
body {
position: relative;
}
.verticalLineFeed {
width: 2px;
height: 100%;
border-left: 5px solid #cdcdcd;
position: absolute;
margin-left: 32px;
}
.main {
width: 100%;
height: 2000px;
}
<div class="verticalLineFeed">
</div>
<div class="main">
</div>
I have got a way to do this
$(document).ready(function() {
function setHeight() {
windowHeight = $('.main').innerHeight();
$('.verticalLineFeed').css('height', windowHeight);
};
setHeight();
$('.main').resize(function() {
setHeight();
});
});
Code Snippet :
$(document).ready(function() {
function setHeight() {
windowHeight = $('.main').innerHeight();
$('.verticalLineFeed').css('height', windowHeight);
};
setHeight();
$('.main').resize(function() {
setHeight();
});
});
.verticalLineFeed {
width: 2px;
height: 100%;
border-left: 5px solid #cdcdcd;
position: absolute;
margin-left: 32px;
}
.main {
width: 100%;
height: 2000px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="verticalLineFeed">
</div>
<div class="main">
</div>
I'm trying to make a fixed box with 980px width and 500px height scrolling inside a div with 100% width and 1500px height, but it is not working at all.
That's what I did: https://jsfiddle.net/zjuyuhmz/2/embedded/result/
The box is moving when the page scrolls, and I want to make scroll only if the mouse is inside of the div.
Is this possible??
Html:
<div id="wrapper">
<div class="main">
<div class="container">
<div class="container2">
<div class="test"></div>
<div class="test"></div>
<div class="test"></div>
</div>
</div>
</div>
</div>
Css:
#wrapper {
position: relative;
width: 100%;
height: 100%;
color: #a3265e;
font-family: 'GillSans-SemiBold';
}
.main {
border: 1px solid red;
position: relative;
width: 100%;
height: 100%;
margin: 0 auto;
padding-top: 380px;
}
.container {
border: 1px solid green;
position: relative;
width: 100%;
height: 500px;
margin: 0 auto;
overflow: scroll;
}
.container2 {
height: 1500px;
margin: 0 auto;
}
.test {
width: 940px;
height: 500px;
position: fixed;
left: 50%;
margin-left: -480px;
background: black;
}
You need to write javascript code, where you can get cursor position and depending on that enable scroll event.
Replace the css for .test for this:
.test {
width: 940px;
height: 500px;
position: absolute;
left: 50%;
margin-left: -480px;
background: black;
}
.test:focus {
position:fixed;
}
This means: when the element with id "test" has the focus on, make it's position fixed. If not, make it's position absolute.
Well i have the following: http://jsfiddle.net/a9VDa/12/
I am trying to make the jquery tree fill the remaining contents of the div "a" but also include a scroll if there isn't enough space.
<div class="a">
<div class="b"></div>
<div class="c" id="tree"></div>
</div>
My suggested solution: http://jsfiddle.net/Bt2sL/2/
Without orange part scrolling.
HTML
<div class="b"></div>
<div class="a">
<div class="c" id="tree"></div>
</div>
CSS
.a {
height: 60px;
background-color: red;
height: auto;
overflow: scroll;
height: 200px; // adjust this to your need
}
.b {
height: 22px;
background-color: coral;
}
.c {
background-color: lightblue;
}
Can you just make div b fixed and add some padding to a with overflow scroll set?
.a {
height: 60px;
background-color: gray;
position: relative;
overflow: scroll;
padding-top: 22px;
}
.b {
position: fixed;
top: 0;
height: 22px;
background-color: coral;
}
.c {
background-color: lightblue;
height: auto;
overflow: scroll;
}
