Although most pages on my site have enough content to push the footer to the bottom of the page for most people. I would like to know it's always fixed to the bottom regardless of screen size from now on anyway. I've tried a number of ways such as bottom:
0x; position:absolute: etc. Never seems to work very well, occasionally pushes the footer out of it's container to fix to the bottom using some of those examples right there. Included is the HTML and CSS for the two parts of the footer (footer & copyright
bar). They're both inside of a div anyway. I removed my attempts at getting it to stick so people can have a look at it right now and see what the current code is to amend. Although most pages on my site have enough content to push the footer to the

Like this add position:fixed; and bottom:0; below the selector #footer:

CSS

#footer {
background-color: #F3F3F3;
padding-top: 10px;
padding-bottom: 0px;
position:fixed;
bottom:0;

I've found the sticky footer solution a bit painful on responsive sites, given that the height of your nav and footer can differ depending on the device. If you only care about working on modern browsers, you can accomplish your goal using a bit of Javascript.

If this is your HTML:

<div class="nav">
</div>
<div class="wrapper">
</div>
<div class="footer">
</div>

Then use this JQuery on every page:

$(function(){


/* Sets the minimum height of the wrapper div to ensure the footer reaches the bottom */
function setWrapperMinHeight() {
$('.wrapper').css('minHeight', window.innerHeight - $('.nav').height() - $('.footer').height());
}
/* Make sure the main div gets resized on ready */
setWrapperMinHeight();


/* Make sure the wrapper div gets resized whenever the screen gets resized */
window.onresize = function() {
setWrapperMinHeight();
}
});

Set

html, body {
height: 100%;
}

Wrap the entire content before the footer in a div.

.wrapper {
height:auto !important;
min-height:100%;
}

You can adjust min-height as you like based on how much of the footer you want to show in the bottom of the browser window. If set it to 90%, 10% of the footer will show before scrolling.

Here's a simple CSS solution that'll work:

#fix-footer{
position: fixed;
left: 0px;
bottom: 0px;
height: 35px;
width: 100%;
background: #1abc9c;
}

Your footer element won't inherently be fixed to the bottom of your viewport unless you style it that way.
So if you happen to have a page that doesn't have enough content to push it all the way down it'll end up somewhere in the middle of the viewport; looking very awkward and not sure what to do with itself, like my first day of high school.

Positioning the element by declaring the fixed rule is great if you always want your footer visible regardless of initial page height - but then remember to set a bottom margin so that it doesn't overlay the last bit of content on that page. This becomes tricky if your footer has a dynamic height; which is often the case with responsive sites since it's in the nature of elements to stack.

You'll find a similar problem with absolute positioning. And although it does take the element in question out of the natural flow of the document, it still won't fix it to the bottom of the screen should you find yourself with a page that has little to no content to flesh it out.

Consider achieving this by:

Declaring a height value for the <body> & <html> tags
Declaring a minimum-height value to the nested wrapper element, usually the element which wraps all your descendant elements contained within the body structure (this wouldn't include your footer element)

Code Pen Example

$("#addBodyContent").on("click", function() {
$("<p>Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. Vestibulum tortor quam, feugiat vitae, ultricies eget, tempor sit amet, ante. Donec eu libero sit amet quam egestas semper. Aenean ultricies mi vitae est. Mauris placerat eleifend leo.</p>").appendTo(".flex-col:first-of-type");
});


$("#resetBodyContent").on("click", function() {
$(".flex-col p").remove();
});


$("#addFooterContent").on("click", function() {
$("<p>Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. Vestibulum tortor quam, feugiat vitae, ultricies eget, tempor sit amet, ante. Donec eu libero sit amet quam egestas semper. Aenean ultricies mi vitae est. Mauris placerat eleifend leo.</p>").appendTo("footer");

A very simple example that shows how to fix the footer at the bottom in your application's layout.

/* Styles go here */
html{ height: 100%;}
body{ min-height: 100%; background: #fff;}
.page-layout{ border: none; width: 100%; height: 100vh; }
.page-layout td{ vertical-align: top; }
.page-layout .header{ background: #aaa; }
.page-layout .main-content{ height: 100%; background: #f1f1f1; text-align: center; padding-top: 50px; }
.page-layout .main-content .container{ text-align: center; padding-top: 50px; }
.page-layout .footer{ background: #333; color: #fff; }

<h1>Fix footer always to the bottom</h1>
<div>
This is how you can simply fix the footer to the bottom.
</div>
<div>
The footer will always stick to the bottom until the main-content doesn't grow till footer.

Even if the content grows, the footer will start to move down naturally as like the normal behavior of page.

<td class="footer">

We can use FlexBox for Sticky Footer and Header without using POSITIONS in CSS.

.container {
display: flex;
flex-direction: column;
height: 100vh;
}


header {
height: 50px;
flex-shrink: 0;
background-color: #037cf5;
}


footer {
height: 50px;
flex-shrink: 0;
background-color: #134c7d;
}


main {
flex: 1 0 auto;
}

<div class="container">
<header>HEADER</header>
<main class="content">


</main>
<footer>FOOTER</footer>
</div>

Using Flex and Bootstrap4 (if you don't use Bootstrap4, you can achieve the same result using the flex properties)

<body class="d-flex flex-column">
<div>Header</div>
<div>Main container</div>
<div class="mt-auto">Footer</div>
</body>

You can use Grid Layout. It is newer than Flexbox, and less supported in browsers.

Check it out:

HTML

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

CSS

html {
height: 100%;
}


body {
min-height: 100%;
display: grid;
grid-template-rows: 1fr auto;
}


.footer {
grid-row-start: 2;
grid-row-end: 3;
}

My solution:

html, body {
min-height: 100%
}


body {
padding-bottom: 88px;
}


footer {
position: absolute;
bottom: 0;
width: 100%;
height: 88px;
}

This code working for me :

footer{
background-color: #333;
color: #EEE;
padding: 20px;
left: 0;
width: 100%;
bottom: 0;
position: fixed;
}

Important thing you should added bottom:0; and position: fixed;
