What I wanted was to have the footer be at the bottom of browser view ONLY IF the content was not long enough to fill up the browser window (non-sticky).

I was able to achieve by using the CSS function calc(). Which is supported by all modern browsers. You could use like:

<div class="container">CONTENT</div>
<div class="footer">FOOTER</div>

the css:

.container
{
min-height: 70%;
min-height: -webkit-calc(100% - 186px);
min-height: -moz-calc(100% - 186px);
min-height: calc(100% - 186px);
}

Change 186 to the size of your footer.

I tried: http://jsfiddle.net/AU6yD/ as here it's the best option but I had problems when the content of the <div id="wrapper"> started to get too big see evidence.png, what I did to solve this was refreshing the body size everytime I changed the content of that div like this:

var body = document.body,
html = document.documentElement;
body.style.height = 100 + "%";
setTimeout(function(){
var height = Math.max( body.scrollHeight, body.offsetHeight,
html.clientHeight, html.scrollHeight,
html.offsetHeight );
body.style.height = height + "px";
}, 500);

Try with this codepen.io/dendii/pen/LLPKJm media responsive

margin: 0 auto;
min-height: 100vh;
}
.main{
width:100%;

}
.main-inner {

}
@media (max-width: 768px){
.main-inner{
display: block;
}
article,aside{
width:100%;
float:none;
display: block;
}
}

<div class="wrapper">
<header class="top">

<div class="main"><div class="main-inner">

<div class="text-mid">
<div class="center">
Whatever you want to keep.

<footer class="bottom">

Another alternative if you want a main-wrapper to adjust the screen EqualHeight

To make it work responsively when the footer is taller on mobile devices compare to on desktop, you can't really know the footer height. One way to do it is to stretch the footer out to cover the entire screen.

html,
body {
height: 100%;
}


.container {
min-height: 80%;
background-color: #f3f3f3;
}


.footer {
background-color: #cccccc;
box-shadow: 0px 500px 0px 500px #cccccc;
}

<div class="container">Main content</div>
<div class="footer">Footer</div>

This is what I am doing for my page

<h6 style="position:absolute; bottom:0;">This is footer at bottom of page without scrollbars</h6>

小开

I tried this and it works fine so far

position:absolute;
bottom:0;
width:100%;

or

position:absolute;
bottom:0;
left:0;
right:0;

I've solved same problem with jquery

    var windowHeiht = $(window).height();
var footerPosition = $("#asd-footer").position()['top'];


if (windowHeiht > footerPosition) {
$("#asd-footer").css("position", "absolute");
$("#asd-footer").css("bottom", "0");
$("#asd-footer").css("width", "100%");
}

Reworking the jQuery solution. I have it working with resizing the window. When the window is bigger than the page, the footer style's position is "absolute" fixed at the bottom the window. When the window is smaller than the page, the footer stays at the bottom of the page - scrolling off the bottom.

<style>
.FooterBottom {
width:100%;
bottom: 0;
position: absolute;
}
</style>
<script type="text/javascript">
$(document).ready(function () {
FooterPosition();


$(window).resize(function () {
FooterPosition();
});
});


var originalFooterBottom = 0;


function FooterPosition() {
var windowHeight = $(window).height();
if (originalFooterBottom == 0) {
var footer = $("#Footer");
originalFooterBottom = footer.position()['top'] + footer.height();
}


if (windowHeight > originalFooterBottom) {
var footerElement = document.getElementById("Footer");
if (!footerElement.classList.contains('FooterBottom')) {
footerElement.classList.add('FooterBottom');
}
}
else {
var footerElement = document.getElementById("Footer");
if (footerElement.classList.contains('FooterBottom')) {
footerElement.classList.remove('FooterBottom');
}
}


}
</script>

I tried many style only solutions but none of them worked. This Javascript/Style solution works just fine for me, even with its odd mix of jQuery and GetElement.

Thanks to Asad for his post.

I did what Jahmic up top did (won't let me comment yet) except I had to use VH instead of % since I couldn't just apply it to a container class.

#inner-body-wrapper
{
min-height: 70vh;
min-height: -webkit-calc(100vh - 186px);
min-height: -moz-calc(100vh - 186px);
min-height: calc(100vh - 186px);
}

Your issue can be easily fixed by using flexbox. Just wrap your .container and your .footer in a flex container with a min-height: 100vh, switch the direction to column so that they stack on top of each other, and justify the content with space between so that footer will move to the bottom.

.flex-wrapper {
display: flex;
min-height: 100vh;
flex-direction: column;
justify-content: space-between;
}

<div class="flex-wrapper">
<div class="container">The content</div>
<div class="footer">The Footer</div>
</div>

Use a blank div with flex-grow:1 to fill unused spaced right before the footer.

<body style="min-height: 100vh; display: flex; flex-direction: column;">


Any content you want,
put it here. Can be wrapped,
nested, whatever.


<div style="flex-grow:1"></div>


<!-- Any content below this will always be at bottom. -->


<footer>Always way at the bottom</footer>
</body>

Extract the styles to css as needed. This works by setting <body> as display:flex;

小开

You can do exactly what you want using Flexbox, as an example will be:

html, body {
height: 100%;
width: 100%;
}


.wrapper {
display: flex;
flex-direction: column;
min-height: 100%;
}


.content {
flex-grow: 1;
}

as a note the footer must be outside the content element

html structure will be something like follow:

<html>
<body>
<div class="wrapper">
<header></header>
<div class="content">
<!-- Content -->
</div>
<footer></footer>
</div>
</body>
</html>

While this question is old, I want to improve slightly on the great answer by Luke Flournoy.

Luke's answer only works if you have two elements in the wrapper. It's very common to have at least 3: header, main content and footer. With these three elements, Luke's code will space them evenly vertically - most likely not what you want. With multiple elements, you can do this:

.flex-wrapper {
display: flex;
min-height: 100vh;
flex-direction: column;
justify-content: flex-start;
}


.footer {
margin-top: auto;
}

<div class="flex-wrapper">
<div class="header">The header</div>
<div class="content">The content</div>
<div class="footer">The footer</div>
</div>

body{
position:relative;
min-height:100vh;
}
footor{
position:absolute;
bottom:0%;
width:100vw;
}

Wrap your footer with a class as following:

<div class="footer">
<h1>footer content</h1>

Then add following css properties to the footer:

.footer{
position: fixed;
bottom: 0;

}

i had just changed the position to sticky and set top to 100%.Then i go to its parent block and set its min height is 100% This solved my problem.

In my case the parent block was body so i changed the min height of body.

.footer {
position: sticky;
top: 100%;
text-align: center;
width: 100%;
height: 60px;
background-color: #1abc9c;}




body{
margin:0;
padding:0;
min-height:100vh;}

小开

I Found this very simple way, just take the main container add min-height and make the footer sticky

body { /* the main container */
min-height: 100vh;
}


footer {
position: sticky;
top: 100%;
}

There are great answer above, i think the problem is that nowadays most people whant to do this with some framework like React, Next or Vue, these frameworks add another element to wrap all the html rendered by the framework like divs with an id #root #__next so we have to aply the style to that element

To push a footer to the bottom of the page when content is short using tailwind.

Add the following to a class

flex flex-col justify-between min-h-screen

    <div className="flex flex-col justify-between min-h-screen">
<div>
... //your body here
</div>


<Footer/> // your footer here
</div>

In my website i have 3 seperation divs div-header,div-body,div-footer. i put min-height for div-body using javascript(i used window.height()) . so when content is low then it will maintain minimum height.so that the footer always be in bottom.

Best solution to have this done was a previous reply from @DR-MATTH, assuming that the body is the main container:

body {
min-height: 100vh;
}
    

footer {
position: sticky;
top: 100%;
}

I just wanted to add that I had to use this variation min-height: calc(100vh - "any margin top/bottom of any sibling element above the footer"); to make the footer really sticky at the bottom when the page have not enough content and avoiding unnecessary scrolling.

Something like this:

body {
min-height: calc(100vh - 60px);
}


footer {
position: sticky;
top: 100%;
    

}
