How to make a sticky footer using CSS? - css

I want to keep my footer at the bottom of the page. I try this
position: absolute;
left: 0;
bottom: 0;
height: 100px;
width: 100%;
but my footer getting messy. My website is made in WordPress. If possible I don't want to use any plugin for this. And I want to use a pure CSS only.
Here the CSS script
footer #bottom-footer{
background: none repeat scroll 0 0 #FFFFFF;
color: #000000;
border-top: 5px solid #F80000;
text-align: left;
padding: 9px;
font-size: 13px;
}
.footer-wrap a{
color:#000000;
}
.footer-wrap a:hover{
color:#F80000;
}
.footer-logo a {
margin-bottom: 6px;
display: block;
}
.footer-socials {
float: left;
line-height: 0px;
}
.footer-socials a {
border-radius: 100%;
color: #ffffff;
display: inline-block;
font-size: 14px;
height: 30px;
line-height: 30px;
margin-left: 3px;
text-align: center;
vertical-align: middle;
width: 30px;

Following a clean method implemented from an online source no longer available (dead link), the minimum code you should need for your page would be (note - probably best to use #bottom-footer instead of footer #bottom-footer for the selection of your footer - that could be part of the issue):
html {
position: relative;
min-height: 100%;
}
body {
margin: 0 0 100px; /* bottom = footer height */
}
#bottom-footer {
position: absolute;
left: 0;
bottom: 0;
height: 100px;
width: 100%;
}

This works perfect. It's the example from W3SCHOOLS
https://www.w3schools.com/howto/howto_css_fixed_footer.asp
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<style>
.footer {
position: fixed;
left: 0;
bottom: 0;
width: 100%;
background-color: red;
color: white;
text-align: center;
}
</style>
</head>

<h2>Fixed/Sticky Footer Example</h2>
<p>The footer is placed at the bottom of the page.</p>
<div class="footer">
<p>Footer</p>
</div>
</body>
</html>

A couple modern methods using a sprinkle of flex box CSS and the following HTML structure:
<body>
<header></header>
<main></main>
<footer></footer>
</body>
Method 1: (fixed height footer) Apply display:flex and flex-direction:column to the body. Apply flex:1 (flex-grow:1) to the main element.
The main element will grow vertically to occupy any empty space, thus making the footer stick to the bottom.
body {
display: flex;
flex-direction: column;
min-height: 100vh;
margin:0;
}
header {
background-color: #cffac7;
height:50px;
}
main {
background-color: #f8e2ff;
flex:1;
}
footer {
background-color: #fceec7;
height:50px;
}
<header></header>
<main></main>
<footer></footer>
Method 2: (fixed height footer) Apply display:flex and flex-direction:column to the body. Apply margin-top:auto the footer.
You're done, because auto margins inside flex containers absorb all available free space, making the footer stick to the bottom. Note that this is not dependent on main having any height or content. In this case, we've given main no flex rules at all, and so it gets the default value of flex:initial (flex: 0 1 auto).
body {
display: flex;
flex-direction: column;
min-height: 100vh;
margin:0;
}
header {
background-color: #cffac7;
height:50px;
}
main {
background-color: #f8e2ff;
}
footer {
background-color: #fceec7;
height:50px;
margin-top:auto;
}
<header></header>
<main></main>
<footer></footer>
Method 3: (fluid height footer) This is really the same technique as in #1 but with elements that have no intrinsic height. By virtue of the ratio between the (unitless) flex-grow values given to the competing elements, main will grow at five times the rate as the header and footer.
body {
display: flex;
flex-direction: column;
min-height: 100vh;
margin:0;
}
header {
background-color: #cffac7;
flex:1;
}
main {
background-color: #f8e2ff;
flex:5;
}
footer {
background-color: #fceec7;
flex:1
}
<header></header>
<main></main>
<footer></footer>

Bootstrap has a sticky footer you can use.

Working 2019 Solution with CSS Grid
If you're here, then you probably suffered for far too long like I did :)
Here's a solution that will work. It's what I use for my site here:
https://aleksandrhovhannisyan.github.io/
You can verify that it works regardless of how much content is on a page by navigating to a fake URL under my site domain:
I'll keep things very generic and reusable. Below is all the code you need, with a basic DOM consisting of a fixed top navigation/navbar, a main content area, and a sticky footer.
I recommend you run and view it in full-page mode to verify that it works:
body {
display: grid;
/* Replace 80 with your footer height, or with auto for variable-height footers */
grid-template-rows: 1fr 80px;
/* These two are important */
min-height: 100vh;
position: relative;
}
#topnav {
background-color: black;
color: white;
/* Recommended by Google, but adjust as you see fit */
min-height: 64px;
position: fixed;
right: 100%;
top: 0;
width: 100%;
/* This is to ensure that it always appears above everything. */
z-index: 100;
left: 0;
}
#page-content {
grid-row: 1;
/* https://css-tricks.com/preventing-a-grid-blowout/ */
min-width: 0;
/* change as you see fit */
padding-bottom: 64px;
padding-top: 64px;
}
#page-footer {
background: black;
bottom: 0;
color: white;
display: flex;
grid-row: 2;
height: 80px;
position: absolute;
width: 100%;
}
<body>
<header>
<nav id="topnav">topnav stuff goes in here</nav>
</header>
<main id="page-content">
<h1>Page content goes here</h1>
</main>
<footer id="page-footer" class="container">
<div>Made by Name</div>
</footer>
</body>

I found the answer here
Modern Clean CSS “Sticky Footer”
html {
position: relative;

Your element .banner needs height and width rules.
Further: Your css is not properly formatted (unless you are using a preprocessor like sass) it should look like this:
header {

Divider with centred image in CSS?

How can I make this divider with a logo in the centre in CSS? ! I've been trying but didn't even got close yet. What would be the best way to achieve this.
Thank you!
Update
This needs to be placed on top of a bg image so the gaps around the logo must be transparent.
Sorry guys this one is a little tricky I know...
Here's the PNG
Well, if you're background is totally plain then it's relatively straight forward.
The HTML
<header>
<div id="logo">
<img src="http://placehold.it/200x100" alt="Placeholder Image" />
</div>
</header>
The CSS
body {
margin: 0;
background: white;
}
#logo {
width: 200px; /* Width of image */
padding: 40px; /* Creates space around the logo */
margin: 0 auto; /* Centers the logo */
background: white; /* Must be same as body */
position: relative; /* Brings the div above the header:after element */
}
#logo img {
display: block;
}
/* :after pseudo element to create the horizontal line */
header:after {
content: '';
display: block;
width: 100%;
height: 1px;
background: #ccc;
margin-top: -90px; /* Negative margin up by half height of logo + half total top and bottom padding around logo */
}
Working demo here.
EDIT
For situations where the body (or containing div) is not a solid colour, try the following:
HTML
<div id="header">
<div id="logo">
<img src="http://placehold.it/200x100" alt="Placeholder Image" />
</div>
</div>
CSS
body {
margin: 0;
}
#logo {
width: 100%;
}
#logo, #logo:before, #logo:after {
float: left;
}
#logo:before, #logo:after {
content: '';
width: 50%;
min-height: 100px; /* height of image */
border-bottom: 1px solid #ccc;
margin-top: -50px;
}
#logo:before {
margin-left: -120px;
}
#logo:after {
margin-right: -120px;
}
#logo img {
float:left;
padding: 0 20px;
}

OR even an example based on display: table, but this goes a bit wonky when resizing.
http://jsbin.com/ITAQitAv/10/edit
This would be one approach:
.hr {
height: 50px; /* imageheight */
background: #fff url(http://placekitten.com/100/50) no-repeat center;
}
.hr hr {
top: 50%;
position: relative;
}
<div class="hr"><hr /></div>
This would be another:
.hr2{
display: block;
border-top: 2px solid black;
height: 2px;
}
.hr2 img {
display: block;
margin: auto;
margin-top: -31px; /*img-height /-2 + height / 2 */
/* adjustments for 'margin' to border */
padding: 0 20px;
background: #fff;
}
<div class="hr2"><img src ="http://placekitten.com/100/60"></div>

How to get my negative top margin to be consistent in desktop Safari?

I've added a negative margin to the logo of my site and it appears fine in all browsers I've tested to this point. See here:
The problem is it's not displaying right in Safari desktop. See here:
The HTML is as follows:
<hgroup id="logo_container">
<div id="logo_inside_container">
<h1 id="site-title"><img src="/wp-content/uploads/logo.png" alt="612 Vineyard - Berryville, VA"/></h1>
</div>
</hgroup>
The CSS is as follows:
#site-title {
margin-top: -30px;
display: block;
padding: 0;
width: 190px;
height: 143px;
float: left;
}
#site-title img {
width: 190px;
height: 143px;
}
#logo_container {
display: block;
width: 100%;
height: 100%;
margin: -29px 0 0 !important;
background: url('/wp-content/uploads/logo_stripe_bg.png') 0 41px repeat-x;
}
#logo_inside_container {
display: block;
width: 860px;
height: 143px;
margin: 0 auto;
background: url('/wp-content/uploads/logo_stripe.png') 0 41px no-repeat;
}
I found a way to add browser specific classes to my body class here: http://codebyte.dev7studios.com/post/4180628671/add-browser-to-body-class-in-wordpress
Simply changed #site-title { margin-top: -30px; } to .safari #site-title { margin-top: 0; }
Hope this helps someone!

Vertically centering <div>s with multiple lines

I know it's been asked a few times, but upon playing around a bit I still couldn't center what I need to. What I'm looking to do it center those buttons vertically on the page. I want to put centered text above it, too.
My (sloppy) code: JsFiddle
HTML:
<div>
</div>
CSS:
div {
text-align: center;
}
a {
text-align: center;
margin: auto;
}
.cbtn {
display:inline-block;
width:60px;
height:60px;
border-radius:50px;
background:transparent;
border: solid gray 1px;
margin: 2px;
-o-transition:.5s;
-ms-transition:.5s;
-moz-transition:.5s;
-webkit-transition:.5s;
transition:.5s;
}
.cbtn:hover {
text-decoration:none;
background:#F3734F;
}
#mail {
background-image:url(http://data.novicode.com/data/img/mail.png);
background-position:50% 50%;
background-repeat:no-repeat;
}
Here is one way of doing it, assuming you want the buttons centered both horizontally and vertically on the page.
The HTML is:
<div class="wrap">
<div class="button-wrap">
</div>
</div>
and the CSS is:
html, body {
height: 100%;
width: 100%;
margin: 0;
padding: 0;
}
.wrap {
height: 100%;
width: 100%;
}
.button-wrap {
position: absolute;
left: 0;
right: 0;
top: 0;
bottom: 0;
height: 60px;
width: 350px;
margin: auto;
text-align: center;
}
You need to declare the width and height properties of the body and html elements to be 100%, and the same for div.wrap.
The trick is to wrap the links/buttons in div.button-wrap, which is absolutely positioned and given specific width and height values to match the buttons. The height of 60px is based on the height of the .cbtn, and the width of 350px is 5 times (60px + 2x2px + 2x1px + 4x1em) which is about 350px. However, since we can use text-align: center for centering the inline blocks, the exact width is not too critical, just make it wide enough.
The centering works by setting all the position values to 0 (left/right/top/bottom) and then setting margin: auto.
This is all based on CSS 2.1 so it should work in most browsers. The only limitation is the inline-block property, which IE7 does not recognize.
However, since you are using CSS2 animations, inline-block is probably okay.

.cbtn {
display:block;
width:60px;

background:transparent;
border: solid gray 1px;

}
#mail {
background-image:url(http://data.novicode.com/data/img/mail.png);
background-position:50% 50%;
background-repeat:no-repeat;
}
You could set the following rules on the div:
div {
position: absolute;
left: 50%;
height: 50%;
margin-top: -(height of div);
margin-left: -(width of div);
}

Vertical centering working in almost every browser, but not in IE7

It's actually two part question regarding my simple page (that will be replaced some day with real content), HTML+CSS boilerplate used there for vertical centering and IE7.
http://engitize.net/
Can anyone provide detailed explanation why the page is displayed correctly in non-IE browsers (Chrome, Fx, Opera), almost all semi-recent to recent IEs (IE5.5, IE6, IE8, IE9), but not in IE7?
I am especially interested in: it works in IE6, yet it doesn't work in IE7, because... kind of explanation.
What should be changed to make div#c properly centered vertically in IE7?
I am using specific height for div#c, but used boilerplate is height-agnostic and fix should preserve this feature.
Spoiling other browsers is not an option, unless it's IE5.5 (ok, IE6 too, but only if it is really unavoidable).
Changing <!DOCTYPE html> and turning IEs into quirks mode is also not accepted (and it's a pretty bad practice for newly developed pages).
If you don't have IE7 (just as I), you can visit http://ipinfo.info/netrenderer/ or http://browserling.com/, paste URL there and choose IE7 to see the problem yourself.
Because the page will change after accepting some answer, I'm providing snapshot of relevant HTML and CSS parts from it (with logo URL changed to be absolute).

your Q#1 has been answered by #thirtydot, IE7 and below does not support the CSS table properties so another way has to be found for them. and his absolute positioning technique is usually the preferred way to do this as most times in a scenario like this (splash page?) the width and height of the centred content would be known.
addendum to above per comments:
In answer to why it was working in IE6 and not IE7 even though IE6 doesn't support the table properties either, IE7 was actually picking up the position: static rule from the #middle[id] {} rule - IE7 does understand this type of selector so this means the later absolute/relative positioning was not working the same as it was in IE6
Taking the above into account redoing the CSS to make sure IE7 and 6 got the same CSS and that it was placed later in cascade to override the "good" CSS it turns out the the positioning method is height agnostic too, in the comments there are various links to to test this, but here is the final working version:
Hybrid table cell/positioning method : here
That fiddle does include the image width and heights, but if you remove them and the positioning for the "sub text" it does (or should) show that whatever is in the middle does stay centered
HTML used is the same as the bottom of this answer.. minus the extra <i></i> element
CSS:
html, body { height: 100%; margin: 0; padding: 0;}
body { background-color: #fff; color: #000; }
#outer {
position: relative;
width: 100%;
height: 100%;
display: table;
}
#middle {
display: table-cell;
vertical-align: middle;
text-align: center;
}
#c {
width: 385px;
height: 120px;
margin: 0 auto;
background: url(http://engitize.net/engitize.png) no-repeat 50% 50%;
}
/**** for IE7 and below ****/
/* hacks but there is another method below */
#middle {
*position: absolute;
*top: 50%;
*width: 100%;
*text-align: center;
}
#c {
*position: relative;
*top: -50%;
}
/**** end IE7 and below rules ****/
#c div {
position: relative;
top: 100px;
width: 100%;
color: #666;
font-weight: bold;
font-family: serif;
font-size: 12px;
text-align: right;
}
#footer {
width: 100%;
text-align: center;
height: 15px;
padding: 5px 0 0 0;
margin: -20px auto 0 auto;
border: 0;
background-color: #def;
}
#footer div {
padding: 0px 5px 0px 5px;
text-align: right; font-size: 10px;
font-family: sans-serif;
}
#footer p {margin: 0;}
As pointed out in comments using the technique that the HTML5 boilerplate uses to class the HTML element conditionally see:
Conditional stylesheets vs CSS hacks?
Answer: Neither!
means you could replace the IE7 hacks with:
.ie6 #middle, .ie7 #middle {
position: absolute;
top: 50%;
width: 100%;
text-align: center;
}
.ie6 #c, .ie7 #c {
position: relative;
top: -50%;
}
Original alternative - "Matchstick Technique"
You could likely mix the following technique with the "table-cell" technique via conditional comments or hacks, but this (hacky!) technique works across browser as far as my tests have seen
As you've asked for a height agnostic version.. you might or might not like the "matchstick" technique, this involves using inline blocks and lining them up.. the "matchstick" is a 100% high empty, off page, inline-block element with its vertical-alignment set to "middle" once it's in place the next inline-block (your actual content div) sits beside it and aligns to the middle or it, then using text-align: center; on it you have the horizontal centering too
here's a link to a working example fiddle
Note: I've left your widths intact, but you can test without widths/heights by removing the height & width off #c and also remove the CSS for the #c div text div - in a plain text scenario entering text into either of these divs should 'auto' centre.
and especially note the insertion of the extra <i></i> HTML just inside the outer div (that's likely why this is not a preferred method!), this is the "matchstick" that props the whole page open.
Code used in fiddle:
html, body { height: 100%; margin: 0; padding: 0; }
body { background-color: #fff; color: #000; }
#outer { position: relative; width: 100%; height: 100%;}
/* a matchstick spacer */
#outer i {
display: inline-block;
height: 100%;
width: 1px;
margin-left: -1px; /* to hide off page */
margin-right: -4px; /* to remove spacing between this and #middle block */
vertical-align: middle; /* will make inline block next to it center vertically */
background: #f00; /* red, not required just to see or not see it */
}
#middle {
display: inline-block;
width: 100%;
text-align: center;
vertical-align: middle;
}
/* image 385 * 120 */
#c {
display: inline-block;
/* presuming image heights, but it wouldn't matter if there was width/height here or not */
width: 385px;
height: 120px;
background: url(http://engitize.net/engitize.png) no-repeat 50% 50%;
}
#middle, #c { /* IE hack for inline block on block level elements */
*display: inline;
}
#c div { position: relative; top: 100px; width: 100%; color: #666; font-weight: bold; font-family: serif; font-size: 12px; text-align: right; }
#footer { width: 100%; text-align: center; height: 15px; padding: 5px 0 0 0; margin: -20px auto 0 auto; border: 0; background-color: #def; }
#footer div { padding: 0px 5px 0px 5px; text-align: right; font-size: 10px; font-family: sans-serif; }
a { text-decoration: none; color: #006; }
a:hover { color: #00c; }
p { margin: 0px; padding: 0px; }
HTML:
<div id="outer">
<i></i>
<div id="middle">
<div id="c"><div>
because history is important!
</div></div>
</div>
</div>
<div id="footer">
<div>
<p style="float:left;"><strong>Przemys?aw Pawe?czyk</strong>'s imprint | Coming in 2012!</p>

IE7 does not support display: table-cell, which you're using as part of your vertical centering technique.
Your page was relatively simple, so I simplified the HTML/CSS a lot. The centering now works properly everywhere I've tested it.
Complete code: http://jsbin.com/azuhe4
The line that's causing this behavior is...
position: static
...on the "#middle" CSS spec.
If I disable that line IE7 seems to render (more or less) the logo in the middle of the page.
It's the <!DOCTYPE>.
IE6 & 7 were a little flaky with that (that's what I've read, anyway).
If you do the following, you'll see things come around - with your code (no edits, save for a couple borders to see what's happening).
Here's what I did:
Deleted your <!DOCTYPE>
Added to your DIV {} CSS line - border:1px dotted gray
At your "outer", "middle", and "c" divs, a threw an inline border-color just to see which was which.
Hit Refresh
Then pasted <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">, and hit Refresh again. Looked fine to me. Centered vertically, horizontally.
As of April 20, 2011 W3C states <!DOCTYPE HTML> as "Not a Standard". Certainly, IE6/7 have no idea what that tag means. http://www.w3.org/QA/2002/04/valid-dtd-list.html
I got new and easy solution for that:
<style>
.vam{vertical-align:middle;}
</style>
<div style="line-height:200px; border:1px solid #000000; height:200px;
text-align:center;color:#FFFFFF; font-size:1px;">
.<img src="her-banner.jpg" alt="" class="vam" />
</div>
