Getting the footer on the bottom of the page - javascript

This dreaded problem.
What I currently have
html:
<html>
<body>
<div class="wrapper"></div>
<div class ="footer"></div>
</body>
</html
css:
* {
margin: 0;
}
html, body {
height: auto !important;
height: 100%;
}
.wrapper {
min-height: 100%;
height: auto !important;
height: 100%;
margin: 0;
}
.footer
height: 36px;
}
The problem is when i inspect the rendered page with chrome a few problems I see:
1. The html tag has a height associated with it hmmm and its not the entire page height
2. so I have div inside of the wrapper div that extends past the wrapper, body, and html tag?
My best guess is that if i can get the html to the page height I could style the footer to page bottom.
I was considering using javascript to grab the true height in pixels and passing that to height and ditching the percent. Only problem is I still want to know whats going on!
Thanks,

add this css to your wrapper divs
wrapper_div{ overflow:hidden; }
this is a hack to recalculate floated elements inside an element. Otherwise the browser will forget about the floated elements, overflow-hidden does the trick or you can append a clear floated element to the bottom of the wrapper div like so
CSS
clear_float{
clear:both; display:block;
overflow:hidden; visibility:hidden;
width:0px; height:0px;
}
HTML
<div class="wrapperdiv">
/* other HTML elements*/
<div class="clear_float"></div>
</div>
this is assuming that the troublesome div is classed wrapperdiv
on second look this is completely invalid
html, body {
height: auto !important;
height: 100%;
}
.wrapper {
height: auto !important;
height: 100%;
}
you are setting the height twice in one declaration. height: auto !Important will take precedent over height: 100% so you need to decide whether you want your height automatically rendered over explicitly at 100%.
and your missing the opening block in this css declaration
.footer
height: 36px;
}

Just before the closing tag of the wrapper add a div with the class 'clear'
CSS:
.clear { clear: both; }
.footer { margin-top: -36px; }
The problem is that floated elements behave like absolute positioned elements.. They are not taken in account when calculating the height of the wrapper div.

In the end I just made the html body tags set via pixels and not percent. Nothing I tried above satisfied me.

If you want a facebook like fixed footer status bar. Try using the following css:
.footer {
width: 100%;
height: 25px;
position: fixed;
bottom: 0px;

How to make an absolute positioned div fill the entire document area

I need to have an absolute div that is a child of only body fill the entire document area (window + any scroll area)
-- width: 100% only fills the viewable screen
I prefer a CSS only solution but pure javascript is ok. I tried without success setting:
opaque.style.minHeight = Math.max(document.body.offsetHeight, document.body.scrollHeight);
I made a jsFiddle of the code below. If you scroll down the output, you will see that the opaque div stops at whatever height the output window was when it was rendered.
In case you are wondering... it is to make an opaque overlay of all content in the div behind it (think slideshow). My only other solution is to disable scrolling, but this is problematic.
Thanks for any help.
<div class="page-container"></div>
<div id="opaque"></div>
body {
width:100%;
}
.page-container {
position: relative;
max-width:978px;
width: 100%;
min-height:2500px;
margin:0 auto -50px auto;
border:solid #999;
border-width:2px;
background: lightblue;
}
#opaque {
position: absolute;
top: 0px;
left: 0px;
width: 100%;
height: 100%;
z-index: 100;
background: grey;
filter: alpha(opacity=70);
opacity: 0.7;
}
Can use
#opaque {
position: fixed;
top: 0;
left: 0;
right:0;
bottom:0;
}
remove width:100% from body due to creates horizontal scrollbar
Depending on use case it is often common to add class to body when using such an overlay that sets body overflow to hidden
DEMO
You can put a position: relative on your body so that the body will be used as a reference point by the child element in terms of height (as opposed to the document object).
Using javascript to set one elements height equal to anothers
var o = document.getElementById('opaque');
var p = document.querySelector('.page-container');
o.style.height = window.getComputedStyle(p).getPropertyValue("height");

Put two 100% width divs side-by-side

So if I want to have two divs, each of 100% of the entire page, side by side, given that the wrapper has overflow:hidden, how should I go about implementing it?
I have tried using inline-block but it did not work.
I have tried using float too but it caused errors.
I want the second div to be hidden so I can change it's left as an animation, sort of like a slide.
Thanks in advance!
If I've understood you correctly, you can achieve what you're after using inline-block. You just have to be a little careful with white space (i.e. you need to make sure you've got no white space between the two child div elements). I've stopped the divs from wrapping by setting white-space: nowrap;.
<div class="foo">
<div> woo woo !</div><div> woo woo !</div>
</div>
.foo {
overflow: hidden;
white-space: nowrap;
}
.foo > div {
display: inline-block;
vertical-align: top;
width: 100%;
background: aqua;
}
.foo > div + div {
background: lime;
}
Try it out at http://jsfiddle.net/8Q3pS/2/.
Edit: Here's an alternative implementation using position: absolute;: http://jsfiddle.net/8Q3pS/5/. That way you'll be able to animate the second one into view using left. Note that you'll need to set a height on the parent div.
.foo {
position: relative;
width: 100%;
height: 1.5em;
overflow: hidden;
}
.foo > div {
position: absolute;
top: 0;
left: 0;
width: 100%;
background: aqua;
}
.foo > div + div {
left: 100%;
background: lime;
}
This should be purely a matter of positioning one of the divs off the page using absolute positioning and transitioning the left property using either hover state or javascript.
Hover the red div.
Codepen Example
Could you not set max-width to 100%, not set the actual width and float them side by side? With both overflow:hidden, as they expand it should create horizontal scrollbars.

Filling available space in set of slide toggles

I have 2 divs with content that uses JQuery slidetoggle to show/hide, but I want the second to occupy all the remaining vertical height of the screen.
$('.heading').click(function (e) {
$(e.target).parent().children('.content').slideToggle("fast", "swing");
});
jsFiddle I started: http://jsfiddle.net/LMHgM/
Any ideas how this can be done without resorting to javascript? Hopefully this should be browser resizing and other element resizing should keep this greedy div in the correct state. Currently my only solution has been to trigger my own resize method on slidetoggle and browser resize to correct the height.
Thanks.
You should specify the height as 100% to the element and also to the body and html
DEMO http://jsfiddle.net/kevinPHPkevin/LMHgM/3/
body, html {
height:100%;
}
#second {
border: 1px dashed blue;
height:100%;
}
Basically it is collapsing to fit content, not expanding to fit the page. You can also put a wrapper div around the divs with position: absolute and height: & width: 100%
Updated fiddle: http://jsfiddle.net/LMHgM/2/
.wrapper{
position: absolute;
height: 100%;
width: 100%;
}
Seems the best solution is to use display: table to divide up the screen.
.wrapper {
width: 100%;
height: 100%;
display: table;
border-collapse: collapse;
}
.group {
display: table-row;
}

Centered layout with the sidebar extension to the right of the screen

I'm trying to create a fixed layout, with the sidebar's background extend to the far right. I drew a sketch to illustrate the image:
how would I go about extending the sidebar background to extend till the end of the right screen, on any window size? I tried with:
#sidebar {
z-index: 1000;
overflow: hidden;
position: absolute;
width: 100%;
background: url(../img/sidebar-base.png) no-repeat 0 -8px;
min-height: 200px;
&::after {
content: '';
z-index: 10;
display: block;
height: 100px;
overflow: hidden;
width: 100%;
background: url(../img/sidebar-rx.png) repeat-x 0 -9px;
position: absolute;
top: 0;
}
}
but a scroll would appear horizontally, and if I apply overflow:hidden on the body I wouldn't be able to scroll to the bottom. Thank you!
EDIT: I did try to find my luck with javascript but there's still a little scroll:
$(function(){
$sidebar = $('#sidebar');
$sidebar.css({width: window.innerWidth - ($sidebar.offset().left)})
});
If your problem lies only in the scrolling, you can easily fix this with this line
overflow-x: hidden;
and applying it to the background's parent or the body element altogether.
Is there anyone following here or not? anyway, I think you should static position and hidden overflow like below:
#sidebar {
z-index: 1000;
overflow: hidden;
position: static;
width: 100%;
height:100%;
right:0;
top:0;
margin:0;}
Also to hide the scrolls, you should hide your body overflow too.
Hope to be right and helpful...
Set body to 100%
body {
height: 100%;
}
Then set the sidebar height to "height: auto;". That will make it extend to the height of the viewport. From there, add fixed positioning like you said.
You could do:
overflow-y:hidden
That should get rid of the scroll bar across the bottom.
I would also then use a lot of right hand padding in the sidebar to extend it out.
Try setting the sidebar width to 30% and the content to 70%.
What you should do is create a wrapper div.
<div class="sidebar-parent">
<div class="sidebar"><!-- Stuff Here --></div>
</div>
Your document should look like this when finished:
<html>
<head>
<title>Experiment</title>
<style type="text/css">
.content {float: left; width: 49%; height: 500px; border: 1px solid #000;}
.sidebar-parent {float: left; width: 50%; background-color: green;}
.sidebar {width: 500px; height: 500px; border: 1px solid #000;}
</style>
</head>
<body>
<div class="content">blah blah blah</div>
<div class="sidebar-parent">
<div class="sidebar"><!-- Stuff Here -->blah blah blah</div>
</div>
</body>
</html>
The main thing to remember is the container div "sidebar-parent" is what's getting the width and containing the background.
To center them you'll need width: 50%; parent containers for both content and sidebar. You make those float:left; to fill the screen and then the content child container float: right; and the sidebar child container float: left; within their parent containers.
Summary: 2 50% width containers each containing 1 child container. Stack the parents together with a left float and then position the fixed width child containers within their parents.
That will center them and now you'll have the ability to have extended backgrounds.

Sticky footer, along with scrolling div without specific height

I'd like a page with a sticky footer, and I'd like the content above it to be scroll-able, while maintaining the stickiness of the footer. But I don't want to hard-code the height of the content area, but instead would like its height to be all the available height except for the height of the footer.
In the long run I would even like for the height of the scroll-able content area to be re-sizable if the window is re-sized, but I'm getting ahead of myself. I'm presuming I'm going to need a combination of CSS and Javascript to acheive this, that CSS alone cannot acheive it?
I've researched of course and have found the CSS overflow property, but my CSS in general is not very good :( Below is some CSS/HTML I've cobbled together based on ryanfait.com's sticky footer tutorial, if somebody can give me some advice using this as a starting point. Bear in mind, I will need straight Javascript, not jQuery, as this will be used in a custom browser (http://tkhtml.tcl.tk/hv3.html). My Javascript unlike my CSS though is pretty good, so an answer combining specific CSS suggestions with general Javascript suggestions (which I will then flesh out), would be ideal.
<html>
<head>
<style>
* {
margin: 0;
}
html, body {
height: 100%;
}
.wrapper {
min-height: 100%;
height: auto !important;
height: 100%;
margin: 0 auto -4em;
}
.footer, .push {
height: 4em;
}
</style>
</head>
<body>
<div class="wrapper">
<p>Your website content here.</p>
<div class="push"></div>
</div>
<div class="footer">
<p>Copyright (c) 2008</p>
</div>
</body>
</html>
EDIT: What I've attempted based on first two answers:
I've made the following modifications to the CSS based on parts of the two answers received so far:
<style>
* {
margin: 0;
}
html, body {
height: 100%;
}
.wrapper {
min-height: 100%;
height: auto !important;
height: 100%;
margin: 0 auto -4em;
overflow-y: scroll;
}
.footer {
bottom: 0;
height: 4em;
position: fixed;
}
</style>
What this gives me in Chrome are two scrollbars, one very faint, but the more prominent one still allowing content that overflows (maybe I'm using the term incorrectly?) outside of the wrapper area, and over the top (or under the bottom) of the footer, plus outside the entire body. Thanks for help making progress but I still need quite a bit of help. Here's a link to a screenshot of what I'm seeing; I used http://www.ipsum-generator.com/ to generate all the content.
http://dl.dropbox.com/u/44728447/dynamic_wrapper_sticky_footer.JPG
html, body {
height:100%;
overflow:hidden;
}
.wrapper {
overflow-y:scroll;
height: 90%;
}
.footer {
position:static;
bottom: 0;
height: 10%;
}
Demo: http://jsfiddle.net/vfSM3/
On the footer div use position fixed and bottom 0 like:
.footer {
bottom: 0;
height: 4em;
position: fixed;
}
If you want to use fixed height on the footer, you could do the following
.wrapper{
overflow-y:scroll;
height:calc(100% - 20px);
}
.footer {
position:static;
bottom: 0;
height: 20px;
}
Note that you need to use the spaces here "100% - 20px" in order for it to work.
