I'm trying to implement a sticky footer which is working except that the main wrapping div's 100% height is extending way too tall (#body-wrap) and it's causing a huge gap between the content and the footer. So instead of the footer sitting at the bottom of the screen like it's supposed to, I have to scroll down the page past the huge gap to view it.
I have something like this as my HTML:
<div id="body-wrap">
<div id="content">
[about 100px of content here]
</div><!-- end #content -->
<div class="push"></div>
</div><!-- end #body-wrap -->
<div id="footer-wrap">
<div id="footer-content">
[about 300px of content here]
</div> <!-- end #footer-content -->
</div> <!-- end #footer-wrap -->
And my CSS:
html, body {
height: 100%;
}
#body-wrap {
min-height: 100%;
height: auto !important;
height: 100%;
margin: 0 auto -300px; /* the bottom margin is the negative value of the footer's height */
}
.footer-main-wrap, .push {
height: 300px; /* .push must be the same height as .footer */
}
Anyone have any idea why the a 100% height would extend further than the content?
When you specify height as a percentage (e.g., height: 100%), that's in relation to the parent container, not the contents of the element. If you're not needing to support IE6, you'll probably find this a lot easier to implement using position: fixed for the footer.
Edit: I just noticed another thing - in your markup you have an element with ID footer-wrap, but in your CSS, you're using the selector .footer-main-wrap. Try changing .footer-main-wrap in your CSS to #footer-wrap.
Adding
height 100% to your html
and
height auto to your body will make it adjust correctly when the page isn't long enough

I'm building an angular application that frequently uses nested views. Certain views, however, are taller than the other elements on the page and end up extending well beyond the end of the parent view.
I'm using Ryan Fait's Sticky Footer so I have a wrapper around a containing div set to height:100% and I would have expected the page to just adapt and move the footer to the bottom of the nested view however I'm seeing the style elements of the footer border and background-color are remaining at end of the parent div while the content of the footer is being pushed to the end of the nested div.
Including an image as I'm struggling with getting the language exact:
I'm really looking for any solution from fixing the css to something that seems hackier like changing the footer or using ng-if/ng-class on certain pages. I'm imagining I'm misunderstanding something about CSS/UI-Router but I can't really track it.
The code isn't really interesting but here is it?
CODE
.wrapper {
min-height: 100%;
margin-bottom: -50px;
}
.push {
height: 50px;
}
.footer {
display: block;
height: 50px;
}
.nested {
max-height: 500px;
}
<body>
<div class="wrapper">
<div>
<h1>Some text</h1>
<ui-view class="nested"></ui-view>
</div>
<div class="push"></div>
</div>
<footer class="footer">
<span>some copy</span>
</footer>
</body>
If you use percentage values for height (i.e. a relative height), the parent element heights have to be defined too. In your case you also need height: 100% on body and html, like
html, body {
height: 100%;
}
I have been banging my head against the wall trying to figure out this problem and I have looked high and low for the answer and came up with similar results.
Synopsis
The problem is that I am building a website using the 960 grid and have three columns that I want to stretch at 100% at all times. Here is a fiddle for your reference: http://jsfiddle.net/Uec7h/1/
Essentially the html is like so:
<div class="contentWrapper">
<div class="container_12">
<div class="grid_2 leftSide clearfix">
Left sidebar content.
</div>
<div class="grid_7 content">
Lots of content loaded from the server.
</div>
<div class="grid_3 rightSide">
Right sidebar content.
</div>
</div>
</div>
with the CSS being like
html, body {
height: 100%;
}
.content {
height: 100%;
}
.leftSide {
height: 100%;
background-color: #000000;
}
.rightSide {
height: 100%;
background-color: #000000;
}
.contentWrapper {
height: 100%;
}
The fiddle isn't completely accurate to what I am seeing on my local version, but it's close. Seems like the left and right sidebars do not want to expand to 100% no matter what I do.
What I've Tried
Most of the answers I have found on SO have suggested to put height: 100% on the html, body elements and everything should work out fine. Adding this attribute and giving both sidebars height: 100% did work a little bit, but if the content in the middle column gets too big, it stops at a certain point and won't continue to stretch.
I have tried adding the clearfix class that comes with the 960 grid but it didn't seem to help at all.
Question
How do I get the left and right side bars height in the fiddle to be 100% no matter what content is in the middle column?
If you add the following CSS to the sidebar elements it will fill the 100% of the height.
display:block;
height:auto;
position:absolute;
top:0px;
bottom:0px;
If you place the sidebar into a wrapper div with relative positioning, the content section will be again in it's right place...
I would also set padding and margin to 0 for the body.
EDIT:
If you add height: 100% to the .container_12 it will get a real height, and children elements can have a 100% height. Notice that the sidebars will be as height as the window itself, but your content at the middle can be taller than 100%... Fiddle
Dont know the 960 grid, the EDITED solution - using visibility: visible; -
HTML
<div id="box">
<div class="vision"> sdfsdfsd </div>
</div>
CSS
#box {
float: left;
border: 2px solid red;
}
.vision {
width: 300px;
height: 600px;
visibility: visible;
}
I have a layout where I need to use height: 100% on html and body (and any wrapper divs I resort to using) to achieve an effect similar to pages, so that the content on my first "page" is centred, scrolling down the content on the second "page" is centred etc.
The html looks like this:
<section class="page" id="p01">
<div class="spacer">
</div>
<div class="outer">
<div class="inner">
Some content
</div>
<div class="inner">
Some content
</div>
</div>
</section>
<section class="page" id="p02">
<div class="spacer">
</div>
<div class="outer">
<div class="inner">
Some content
</div>
<div class="inner">
Some content
</div>
</div>
</section>
and the vertical centring etc. achieved with this styling:
body, .page {height: 100%; margin: 0 auto;}
.spacer {
float: left;
height: 50%;
margin-bottom: -150px;
}
.outer {
height: 300px;
width: 100%;
background-color: #fca;
clear: both;
position: relative;
display: block;
white-space: nowrap;
}
.inner {
width: 41%;
margin: 0 6%;
height: 300px;
background-color: green;
display: inline-block;
vertical-align: middle;
white-space: normal;
}
.inner:first-child {
margin-right: 0;
}
You can see it at work in this fiddle:
http://jsfiddle.net/terraling/3V5rV/
The problem is the body background (here I'm just using color, but on my site it will be an image) leaks out into the body margins, i.e. the body content has a max-width and should be centred with white margins.
I can fix that either by... setting html background-color to white, as per
http://jsfiddle.net/terraling/yM53t/
...but body background becomes cutoff when scrolling into the second page (that wasn't a problem in the first fiddle).
Alternatively I could set the background image on a wrapper div and not on the body. That solves the problem of it leaking into the body margins, but it still has the same problem that it is cut off on scrolling.
(see: http://jsfiddle.net/terraling/3V5rV/1/ )
Any solution that involves removing the height: 100% declaration from any of html, body or wrapper collapses the layout (including replacing with max-height: 100%).
There's a whole lot of problems with this construct and not all of them can be solved, unfortunately.
The background issue
As you have seen yourself the background of body extends to the viewport if html does not have a background. That's solvable.
The float issue
When an element floats it does not contribute to the height of its parent element. So they don't grow (e.g. body does not expand). That can be solved if you can use alternatives. For vertically centering an element you could use display: table-cell e.g., which allows you to vertically center the content.
The height issue
This is where all hope is gone. height: 100% refers to the height of the parent, of course. The parent of body is html which in turn is the child of the viewport. You gave html the size of 100% (= the size of the viewport) and body the size of 100% (= size of html = size of viewport).
So now body has a fixed height and it can't expand meaning the background doesn't expand as well. Now one might have the idea to give body no size so that it can expand. But .page has 100% too. If a parent (in this case body) has no fixed size 100% has no meaning and will be treated as auto, which means as big as the content. And the content has a height of 300px. So the .page elements wouild no longer have the height of the viewport but 300px.
As for the collapse of the CSS, you should either specify the height specifically height:200px; or add padding to the bottom/top of the page so that the content wraps. You can also use min-height:200px; then add the margin-bottom:20px; to separate the pages. I would approach this at a specific height with the wrapper having the specific background-image and bottom-margin.
In order to center your background-image to the <html> you can specify the position as 50%.
This can be done by doing background:url('yourimage.jpg') repeat 0 50%;This will ensure the background is centered.
I've found 2 different implementations of a CSS sticky footer:
Ryan Fait sticky footer - http://ryanfait.com/sticky-footer/
Steve Hatcher sticky footer - http://www.cssstickyfooter.com/
Could someone explain the difference between how each of them work?
And if there are other known implementations, could you please post a comment or edit this question?
They are pretty similar in terms of function. The first forces a div to the full height of the page and then give it a negative margin the size of the footer.
html, body {
height: 100%; /*set 100% height*/
}
.wrapper {
min-height: 100%; /*content 100% height of page */
height: auto !important;
height: 100%;
margin: 0 auto -142px; /* negative value causes wrappers height to become (height of page) minus 142px, just enough room for our footer */
}
.footer, .push {
height: 142px; /*Footer is the footer, push pushes the page content out of the footers way*/
}
What this does is makes sure that all content within the wrapping div is 100% of the page height minus the height of the footer. So that as long as the footer is the same size as the negative margin it will stick in the gap left and appear at the bottom of the element.
The second also forces the content to be 100% of the height of the page.
html, body {height: 100%;} /*set 100% height*/
#wrap {min-height: 100%;} /* make content 100% height of screen */
It then creates a space at the bottom of the main content the same size as the footer.
#main {overflow:auto;
padding-bottom: 150px;} /* wrapper still 100% height of screen but its content is forced to end 150px before it finishes (150px above bottom of screen) */
Then using position relative and a negative top margin forces the footer to appear 150px above its normal position (in the space it just made).
#footer {position: relative;
margin-top: -150px; /* Make footer appear 150px above its normal position (in the space made by the padding in #main */
height: 150px;
clear:both;}
Note: This only works so long as your page content is kept within .wrapper and #main inside #wrap respectively, and your footer is outside of these containers.
If you didn't understand any part of that leave me a comment and I'll try to answer it.
Edit: In response to user360122
HTML markup for first:
<html>
<body>
<div class="wrapper">
<!--Page content goes here-->
<div class="push">
<!--Leave this empty, it ensures no overflow from your content into your footer-->
</div>
</div>
<div class="footer">
<!--Footer content goes here-->
</div>
<body>
</html>
HTML markup for second:
<html>
<body>
<div id="wrap">
<div id="main">
<!--Page content goes here-->
</div>
</div>
<div id="footer">
<!--Footer content goes here-->
</div>
</body>
</html>
Remember to include the stylesheet and declare doctype .etc (these aren't full html pages).
There is an example in the bootstrap documentation which seems to be very simple: http://getbootstrap.com/examples/sticky-footer/
No wrapper or push needed.
html {
position: relative;
min-height: 100%;
}
body {
/* Margin bottom by footer height */
margin-bottom: 60px;
}
#footer {
position: absolute;
bottom: 0;
width: 100%;
/* Set the fixed height of the footer here */
height: 60px;
background-color: #f5f5f5;
}
i have a few problems setting up a layout with horizontal sections that should have an automatic height depending on it's content.
This is my page structure.
<div id="#page-wrap">
<header>
<div class="inner">
#navigation
#logo floated right
</div>
</header>
<section id="services">
<div class="inner">
#some floated boxes
</div>
</section>
<section id="main">
<div class="inner">
#secteion content
#aside sidebar
</div>
</section>
<footer>
<div class="inner">
#footer stuff
</div>
</footer>
</div>
header, sections and footer are always 100% wide.
each section has a .inner div which is centered with margin: 0 auto.
.inner {
margin: 0 auto;
padding: 96px 72px 0;
width: 1068px;
color: #3C3C3C;
}
and as example this is my header:
header .inner {
background: #fff url('images/years.png') no-repeat top right;
position:relative;
/*height:100px;*/
}
#logo {
position:absolute;
right:70px;
top:15px;
float:right;
}
THE PROBLEM: if i don't set the header to a specific height the background image get's cut off. If i inspect the header with a develper tool like firebug the navigation inside of it is kind of outside the the header-box. So if i don't set the height of 100px the horizontal navigation cuts off the the background image - even though it's in the same header.
any idea what i have to consider here.
you state that it should have an automatic height depending on its content and then later state the problem is the background gets cut off. so, what exactly are you looking for? a min-height of 100px which expands if the content is larger? or did you expect the nav to be 100px in height (thus forcing the header to 100px)? its a bit confusing... at any rate, the header will have a height of zero if the height is not set and it's children are floats. it sounds to me as if you want the header to be 100px for the purpose of showing the entire background - if so, just set the headers height to 100px (as you've done)
edit// you've also stated that the logo is floated, but then show that its positioned absolutely - which is it? and how is the nav positioned? more information is needed
header, section and footer elements are not container elements - if you want them to behave as if they were you have to set them display: block - this will make them to behave as normal div would
I think this may be a clearfix issue--
you could try adding <div style="clear: both;"></div> before you close your header, or add the following properties to your header
.header {
overflow: hidden;
display: inline-block; /* Necessary to trigger "hasLayout" in IE */
display: block; /* Sets element back to block */
}
however if your navigation will have things that hang out of its container sometimes (like a dropdown), it's best to use something like the method at http://www.positioniseverything.net/easyclearing.html.
finally, you can also try wrapping the whole thing (header, and content) in another div which will only have the background property. that way the bg image will not get cut off.
