I want to have a long page, with a fixed top 100px div, and a fixed 50px bottom div. However, I want the bottom div to scroll as you scroll down the page.
Its hard to explain, but the best example of this is on the front page of PayPal.com
On the first page load, the bottom div looks like it is fixed, and as you adjust the height of the browser window, that div stays at the bottom. Yet as you scroll down the page it is not fixed.
Can anyone explain how they have done this? I am trying to re-create something similar, but cant see how they have managed it.
As far as I can see they have this html...
<div id="fixed-top">
<header class="table-row">
// header content
</header>
<div class="table-row table-row-two">
// Video content
</div>
<div class="table-row">
//bottom content
</div>
</div>
And this CSS...
#fixed-top {
height: 100%;
width: 100%;
display: table;
position: relative;
top: 0;
left: 0;
z-index: 1;
}
.table-row {
display: table-row;
}
But that alone doesn't do it. I also can't see any js thats getting window height and applying it to the main fixed div.
Help! :)
EDIT:
Have just found a way to do it with javascript, controlling the height of the middle row using the window height, minus the 150px for the header and third row.
jQuery(document).ready(function(){
$('div.table-row-two').css({'height':(($(window).height())-150)+'px'});
$(window).resize(function(){
$('div.table-row-two').css({'height':(($(window).height())-150)+'px'});
});
});
But saying that, Zwords CSS only method seems like a winner.
From what I understand, you are looking for something like a sticky footer. So basically if the content is not enough, the footer should go sit at the bottom like its fixed, but if content comes in, it should scroll down like other content.
Try this - http://css-tricks.com/snippets/css/sticky-footer/
First off, you'll need to set the height of the body and html tag, otherwise the table won't take the full screen. Then I altered your code, made it a bit easier.
HTML:
<div id="fixed-top">
<header>
// header content
</header>
<div>
// Video content
</div>
<div>
//bottom content
</div>
</div>
CSS:
html, body {
margin: 0;
padding: 0;
height: 100%;
min-height: 100%;
}
#fixed-top {
display: table;
width: 100%;
height: 100%;
}
#fixed-top > * { /* makes all the direct children of #fixed-top a table row*/
display: table-row;
background: lightblue;
}
#fixed-top > *:nth-child(1) {
background: lightgreen;
height: 40px;
}
#fixed-top > *:nth-child(3) {
background: lightgreen;
height: 25%;
}
You can either set the height to a fix height (in px) or percentages. If you only give two of the three rows a height, the third one will automaticly fill up the rest space.
Also, check this demo.

}
.wrapper .row{
display:table-row;
background-color:rgb(220,220,220);
}
.wrapper .row:nth-of-type(1){
min-height:15px;
}
.wrapper .row:nth-of-type(2){
height:100%;
background-color:white;
}
.wrapper .row:nth-of-type(3){
min-height:15px
}
You can do this easily with jQuery using $(window).height() and subtracting your footer/header's heights. See Fiddle for an example.

I am loading html page inside a div with jquery. It does work fine.
var loginBtn = $("#loginBtn");
var loginPage = $("#login");
var submitBtn = $("#submitBtn");
var submitPage = $("#submit");
var checkBtn = $("#checkBtn");
var checkPage = $("#check");
loginPage.load( "login.html" );
submitPage.load( "submitPoints.html" );
checkPage.load( "checkPoints.html" );
body {
margin: 0 !important;
padding: 0 !important;
background-color: white;
}
#mainFrame {
width: 100%;
height: 300px;
background-color:cadetblue;
padding-top: 0;
margin-top: 0px;
position: relative;
}
<div id="mainFrame">
<div id="login"></div>
<div id="check"></div>
<div id="submit"></div>
</div>
My issue is that if the loaded html has no content, the margin between the parent document body (white) and the top of the loaded html (green) is none (that's what I want, it's ok).
However as soon as I add content to the loaded html, a gap is generated at the top of the page :\
I thought it was all about setting some line-height prop in the css but it seems helpless.
Any ideas what I am doing wrong ?
What you are seeing is the top margin of the first piece of content overflowing its container (also known more commonly as margin collapsing):
body {
background:yellow;
}
#container {
background:green;
height:300px;
}
<div id="container">
<h1>I have a top margin of 1em by default that is overflowing into the body.</h1>
</div>
If you give your container element a padding of that same amount, the margin space of the body won't be used and the element will be pushed down in the green area.
body {
background:yellow;
}
#container {
background:green;
height:300px;
padding:1em;
}
<div id="container">
<h1>I have a top margin of 1em by default that is now contained within my parent.</h1>
</div>
Or, you could set the top margin of the first piece of content to zero:
body {
background:yellow;
}
#container {
background:green;
height:300px;
}
#container > h1:first-child { margin-top:0; }
<div id="container">
<h1>My top margin has been set to zero.</h1>
</div>
Finally, you could set the overflow of the content area to auto but (although this seems to be the popular answer), I don't prefer this approach as you run the risk of unintended fitting of the content as the content changes and/or the container size changes. You give up a bit of sizing control:
body {
background:yellow;
}
#container {
background:green;
height:300px;
overflow:auto;
}
<div id="container">
<h1>The content area has had its overflow set to auto.</h1>
</div>
When you load new content it gets rendered in the document and those new elements might have properties. In this case, most probably the Login has a margin value. Another option is that it has a class or some selector that is being picked up by a CSS file which appends the margin to it.
Easiet way would be to right-click on the Login element, choose inspect, and analyze the style of the element with web-dev / style.
If you want to keep the margin on the inner content, you should set an overflow. Look what happens when we remove the overflow: auto line from .content > div (try clicking the box after running the code sample below).
This is because of margin collapsing. The margin on the inner content is combined with the margin on the outer element and applied on the outer element, i.e. two margins of the two elements are collapsed into a single margin.
document.querySelector('.content').addEventListener('click', (e) => {
e.target.classList.toggle('overflow');
});
html,
body {
margin: 0;
padding: 0;
}
.outer {
width: 200px;
background: red;
}
.content > div {
width: 100%;
height: 300px;
background: cadetblue;
cursor: pointer;
}
.content > div.overflow {
overflow: auto;
}
.test {
margin: 10px;
display: block;
}
<div class="outer">
<div class="content">

Could anyone help me with that?
You can set negative top margin to overlay the second div, see the live example:
<div class="container banner-bottom" style="margin-top:-5%;padding:2%">
http://www.bootply.com/MorC45NB4V
PS: I have used inline css just to show, avoid inline css.
My solution uses jQuery and some calculations. My calculation works even if you move the elements around the document. I also used CSS for the margins you wanted.
jQuery
//location of bottom of the red container
var bottomOfContainer = $('#onTopOfMe').offset().top + $('#onTopOfMe').height();
//gets the bottom 4th of the red container
var placement = bottomOfContainer - ($('#onTopOfMe').height() / 4);
//setter of top for green container
$('#placeMe').offset({"top": placement});
CSS
p.white-text{
margin-left:5%;
margin-right:5%;
}
Output
bootply
1) In case you want your lower banner to have a full width:
You could add position: relative; to the lower banner and position it adding a bottom value and use margin to create the same visual effect asked in the question.
.banner-bottom {
position: relative;
bottom: 45px;
margin: 0 40px;
}
2) In case you don't need to have a banner with full width and just center it, then no need to use margins. Remember to set one parent as position: relative;:
#banner { position:relative;}
.banner-bottom {
position: absolute;
top:75%;
right:0;
bottom:auto;
left:0;
}
CODEPEN
http://codepen.io/alexincarnati/pen/PWOPjY
Here's my solution for this.
Basically just make the position of the card block "relative", position the "top" position accordingly, then set the margin to "auto" to center it.
.card-block {
position: relative;
top: -50px;
margin: auto;
width: 80%;
}
A bit of position could help you, here's a rough version that will hopefully get you thinking what you need to do:
#banner { position:relative;}
.banner-bottom { position: absolute; top:75%;right:0;bottom:auto;left:0; }

The title pretty much says it all. I want the CSS margin: top; on my HTML main_content element to be relative to (a percentage of) the browser window (so that the main_content always stays on the bottom of the browser window. How can I accomplish this?
I've tried this and it doesn't work. (the body {height:100vh} doesn't seem to make body any height as the main_content doesn't stick to the bottom as it should.
body {height:100vh}
#main_content {position:absolute; width:100%; display:block; left:0; bottom:0; text-align:center; padding:20px;}
<div>Extra Infomation </div>
<div id="main_content">
<p>here you can learn about me and my adventures</p>
</div>
(Don't try this right now) If you go to my website, you will see the "learn about me and my adventures" heading, that, along with the "recent activity", and other stuff below that, that is the section I want at the bottom of the browser window, preferably with the "learn about me and my adventures" part just sticking out from the bottom of the page.
Give .main_content a margin-top of 100vh (just beneath the viewport), and then use transformY to pull it back up:
.main_content {
text-align: center;
padding: 20px;
margin-top: 100vh;
transform: translateY(calc(-100% - 20px));
background:lightblue;
}
.below_content{
margin-top:-100px;
}
<div class="wrapper">
<div>Extra Infomation </div>
<div class="main_content">
<p>here you can learn about me and my adventures</p>
</div>
</div>
<div class="below_content">
This is content below the main content
</div>
so put a . before main_content if it is a class and put # if it is an id.
below css code for main_content id should work.
#main_content {
width: 100%;
height: 100px;
position: absolute;
bottom: 0;
left: 0;
}

I'm currently building a responsive site and i need to have a hidden div which will slide in from the left after clicking a button in the the left side bar. Once this button has been pressed the side bar will be pushed across from the sliding content (Sliding from the left) and overlay the existing content or push across the content in the right hand side.
This is where the problem lies as it's a responsive site. I would like the sidebar in the 'siteInnerLeft' div to be pushed to the right hand side of the page when the new div slides in. So after the content has sliden in the previous content is no longer visible until the sliding content has slid back out.
Here is a my JSFiddle - http://jsfiddle.net/76xvB/2/
Hopefuly you can see what i'm trying to acheive. I've manaed to get it working until a point but the issue I have is the content sliding in is fixed and I don't want it to be fixed as there is more content to view and this removes the users ability to scroll.
I understand that 'position fixed' takes the element out of the document flow. So is this going to stop me acheiving what I want? If so, is there another way of doing it.
NOTE: The real site will have percentages not pixels because of it being responsive, this is a broken down version.
My current code:
HTML
<div id="siteWrapper">
<div id="siteInnerLeft">
<div id="homeNavLink">
<p>Click me</p>
</div>
</div>
<div id="siteInnerRight">
<div class="pushmenu-push">
<p>Current page content</p>
</div>
<div class="pushmenu pushmenu-left">
<p>Content to slide in from the left</p>
</div>
<div id="footer">
<p>This is my footer and this content always needs to be showing and can't be hidden behind the fixed div</p>
</div>
</div>
</div>
CSS
#siteWrapper{
max-width:500px;
margin:0 auto;
width:100%;
}
#siteInnerLeft{
background-color:green;
width:100px;
float:left;
position:fixed; /* Sidebar that needs to be fixed*/
}
#siteInnerRight{
width: 400px;
background-color:yellow;
float:left;
margin-left: 100px; /*Compensates for fixed header width */
}
.pushmenu {
background: #e9e8e0;
font-family: georgia,times news roman, times, serif;
position: fixed;
width:400px;
height: 100%;
top: 0;
z-index: 1000;
}
.pushmenu-push{
left: 0;
overflow-x: hidden;
position: relative;
width: 100%;
}
.pushmenu-left{
left:-400px;
}
.pushmenu-left.pushmenu-open {
left: 0px;
/* box-shadow: 5px 5px 5px #d9d8d0;*/
}
.pushmenu, .pushmenu-push {
transition: all 0.3s ease 0s;
}
#footer{
width:100%;
clear:both;
background-color:red;
}
jQuery
$menuLeft = $('.pushmenu-left');
$nav_list = $('#homeNavLink');
$nav_list.click(function() {
$(this).toggleClass('active');
$('.pushmenu-push').toggleClass('pushmenu-push-toright');
$menuLeft.toggleClass('pushmenu-open');
});
Any suggestions would be most appreciated.
Thanks.
On completion of the transition, change the position of the sidebar so that it is not longer fixed. The answer on the following link breaks it down pretty well and has quality references:
Callback when CSS3 transition finishes
If the side-bar is fixed, you could create a scroll-bar inside for the content, so the text can be viewable; you could do this by adding overflow-y: auto; in the .pushmenucss class.
Another way would be to set the sidebar as position: absolute; and then dynamically change the top property from javascript when the user hits the sidebar's bottom.
I have a div which contains 2 divs, one has fixed height.
I want to make sure that the 2nd div's height is exactly as much as the height of the container div minus the other div's height. This height can't be manually set because it's often resized.
<div id="container" style="height: 50%">
<div id="header" style="height: 30px;">
</div>
<div id="content">
</div>
</div>
i have tried with jquery on resize but i think i wrote something wrong:
$(document).on("resize", "#container", function (event) {
$('#content').height($('#container').height()-$('#header').height());
});
Is there any way (Javascript, CSS) to achieve this?
An alternative to the jQuery method is CSS Flexbox:
#container {
display: flex;
flex-direction: column;
}
#content {
flex: 1;
}
See the demo. Unfortunately, this will only work in browsers supporting the latest Flexbox syntax. (http://caniuse.com/#search=flexbox) Backward compatible code is possible using old syntaxes as well, but will be sightly more involved. See David Storey's article at http://coding.smashingmagazine.com/2013/05/22/centering-elements-with-flexbox/ for more on how to do that.
Your main problem seems to be that you have to size the element initially and then keep listening to the resize event:
function handleResize() {
$('#content').height($('#container').innerHeight()-$('#header').height());
}
$(window).on("resize", handleResize);
handleResize();
Also, the resize event should be attached directly to the window.
Otherwise, I recommend the use of innerHeight() for the container as that takes into account padding.
Also I made some fixes to your CSS for this to fully work:
#container {
position: absolute;
width: 100%;
height: 50%;
}
