Flex-box Footer Element Centered - html

I'm making a user-resizable GUI window with a header that gains height through new elements, a footer with static height, and a spacer in between that automatically takes up the rest of the height. I attempted using this answer, but the footer ended up vertically-centered. Picture:
If anyone knows why off the top of their head, it would be greatly appreciated. The element is being added to the page with javascript so the code is pretty messy. Thank you for your time.

What about the following:
<body>
<header class="header"></header>
<main class="spacer"></main>
<footer class="footer"></footer>
</body>
.
html {
height: 100%;
}
body {
display: flex;
flex-direction: column;
min-height: 100%;
}
.spacer {
flex: 1;
}

I still don't know what the issue was, but I made a solution using the css calc() function.
HTML:
<div id="myWindow">
<div id="header">
Header
</div>
<div id="footer">
<div id="subHeaderContainer">
<div id="subHeader">
Sub Header
</div>
</div>
<div id="subFooter">
Sub Footer
</div>
</div>
</div>
CSS:
#myWindow {
width: auto;
height: auto;
resize: both;
border: 2px solid black;
overflow:hidden;
}
#header {
height: 20px;
background-color: grey;
}
#footer {
width:100%;
height: calc(100% - 20px);
}
#subHeaderContainer {
width:100%;
height: calc(100% - 30px);
}
#subFooter {
width:100%;
height:30px;
}

Height 100% and css issue with footer

I am currently working on a script and in some pages there isn't enough content.In this case I want the page to cover 100% of the browser and put the footer at the bottom.I tried many codes and nothing seems to work I ended up by having a code like this:
<div class="container">
<div id=nav>
NAV
</div>
<div id=core>
<div id=content>
<div id=tophea>
TOP Content
</div>
<div id=msgs>
MSG Content
</div>
</div>
<div id="footer">
Footer
</div>
</div>
</div>
and css like this :
#container{
height:100%
}
#nav{
height:55px;
}
#core{
height:100%
}
#content{
height:100%;
background:red;
}
Here is my jsfiddle : https://jsfiddle.net/k8k7o36b/
Any help will be appreciate. I'll be more than thankful if you add small explanation so I can understand what were I doing wrong.
Thanks
#container{
height:100%
}
#nav{
height:55px;
}
#core{
height:100%
}
#content{
height:100%;
background:red;
}
#footer {
background-color: orange;
position: absolute;
left: 0;
bottom: 0;
height: 100px;
width: 100%;
overflow:hidden;
}
<div class="container">
<div id=nav>
NAV
</div>
<div id=core>
<div id=content>
<div id=tophea>
TOP Content
</div>
<div id=msgs>
MSG Content
</div>
</div>
<footer id="footer">
Footer
</footer>
</div>
</div>
This should do it. I changed div to a footer and added some styling to the #footer id so that it has a position: absolute; and bottom: 0;. You can look into what position: absolute does here.
Edit: Obviously, you can adjust the height of the footer however you want, I just set it to 100px and background-color orange so that we can see it better.
You can try with flexbox:
Note you need to use 100% on html and body and also your footer element at the same level of nav and core
html,body {
margin: 0;
height: 100%;
}
.container {
background: orange;
min-height: 100%;
display: flex;
flex-direction: column;
}
#nav {
flex: 0 0 auto;
height: 55px;
}
#core {
flex: 1 0 auto;
background: red;
}
<div class="container">
<div id=nav>
NAV
</div>
<div id=core>
<div id=content>
<div id=tophea>
TOP Content
</div>
<div id=msgs>
MSG Content
</div>
</div>
</div>
<div id="footer">
Footer <br> footer
</div>
</div>
You can use a flex layout and set the main content area to flex-grow: 1 so it will consume all of the available space between your nav and footer, and that will push the footer to the bottom of the page when there isn't enough content.
body,
.container {
min-height: 100vh;
margin: 0;
}
.container,
#core {
display: flex;
flex-direction: column;
}
#core,
#content {
flex-grow: 1;
}
<div class="container">
<div id=nav>
NAV
</div>
<div id=core>
<div id=content>
<div id=tophea>
TOP Content
</div>
<div id=msgs>
MSG Content
</div>
</div>
<div id="footer">
Footer
</div>
</div>
</div>
You can use calculations in css to help with this.
#core {
height: (100vh - 55px)
}
100vh is 100% of the viewport, while he 55px is the height of the footer. Add any other elements to the calculation if you give them a height also e.g.
#header{
height: 45px
}
#core {
height: (100vh - 100px)
}
html,body,#container{
height:100%
}
#nav{
height:55px;
}
#core{
height:100%
}
#content{
height:100%;
background:red;
}
#footer{
position:absolute;bottom:0;
right:0;left:0
}
<div class="container">
<div id=nav>
NAV
</div>
<div id=core>
<div id=content>
<div id=tophea>
TOP Content
</div>
<div id=msgs>
MSG Content
</div>
</div>
<div id="footer">
Footer
</div>
</div>
</div>
</div>
Add these classes
html,body{
height:100%
}
#footer{
position:absolute;bottom:0;
right:0;left:0
}
Here is a generic flexbox solution.
flex-grow: 1; tells main to fill the remaining space. This also has the benefit of not having to set a specific height on your footer.

Firefox 28+

}

}

Footer height doesn't fill screen?

I've been testing my site on multiple devices, and when testing on a screen with high resolution there is all this extra white space underneath the footer.
How do I make the height dynamic, fixing this issue?
My HTML is as follows:
<div class="contact">
<div class="content--container">
........
</div>
<div class="container">
<div class="columns is-multiline">
<div class="column is-12">
.......
</div>
</div>
</div>
</div>
<div class="footer">
......
</div>
A quick and easy fix would be to add a min-height to your .contact element.
Assuming it sits directly insider your body element, and if your footer height is 200px, you could do:
.contact {
min-height: calc(100% - 200px);
}
This does require that your body is either position:static; (the default) or has a min-height of 100%.
Add a min-height to your body like this:
body {
min-height: 100%;
}
Change your footer position to absolute like this:
.footer {
position: absolute;
}
Position and add width to your footer like this:
.footer {
position: absolute;
bottom:0;
left:0;
width: 100%;
}
Try to add these for CSS (it's from http://mystrd.at/modern-clean-css-sticky-footer/):
html {
position: relative;
min-height: 100%;
}
body {
margin: 0 0 100px; /* bottom = footer height */
}
footer {
position: absolute;
left: 0;
bottom: 0;
height: 100px;
width: 100%;
}
HTML template for that is:
<!DOCTYPE html>
<head>
<title></title>
</head>
<body>
<nav></nav>
<article>Lorem ipsum...</article>
<footer></footer>
</body>
</html>
Next option is to use flexbox like these example: https://philipwalton.github.io/solved-by-flexbox/demos/sticky-footer/
In these example body has class="Site" and content also have a class called class="Site-content" and looks like these:
<body class="Site">
<header>Your header</header>
<main class="Site-content">
<div> Text </div>
</main>
</body>
CSS for these example looks like:
.Site {
display: flex;
min-height: 100vh;
flex-direction: column;
}
.Site-content {
flex: 1;
}
Full source for the Site component used in this example you can find here: https://github.com/philipwalton/solved-by-flexbox/blob/master/assets/css/components/site.css
Another easy way to make a footer look like it has a dynamic height (if a tall footer height doesn't matter to you) is by changing the body's background-color to match the footer's. Then you can give one of your containers a 100% width and apply a different background-color.
That gives you the visual separation of the content and the footer without having to position or resize the footer.
Heres's the CSS:
body {
background-color: tomato;
height: 100%;
}
header {
color: white;
padding: 20px;
}
.container {
background-color: white;
height: 200px;
padding: 20px;
width: 100%;
}
footer {
background-color: tomato;
color: white;
padding: 20px;
}
and the HTML:
<header>
<h1>This is my header</h1>
</header>
<div class="container">
<p>This is my content</p>
</div>
<footer>
<p> this is my footer that looks like it has a variable height.</p>
</footer>

Aligning full width fixed header with main content?

First question so sorry if this is a bit squiffy.
I'm trying to get a full (100%) width fixed header with content within, such as logo and navigation links, that is aligned to the main container. I'd like to do this without the use of margining left or right on the logo/nav content as that doesn't seem particularly flexible.
I tried putting the header div within the container block, that fixes the alignment issue but then I can no longer go full width.
So basically how do I get content in a full width fixed header to align with content in the main content of the page?
Here is my html (sorry if its messy, I've only been at this a week or so):
<body>
<div id="header">
<div id="logo">
</div>
<div id="nav">
</div>
</div>
<div id="container">
<div id="content">
</div>
</div>
<div id="footer">
</div>
</body>
Here is my CSS, I left the logo image out and in place is just a beige block:
body {
margin: 0px;
background-color: darkgray;
}
#header{
width: 100%;
height: 100px;
position: fixed;
top: 0px;
background-image: url("images/bg-header.jpg");
opacity: 0.9;
}
#logo {
height: 100%;
width: 300px;
background-color: beige;
}
#container {
width: 960px;
margin: 0px auto;
height: 1000px;
background-color:gray;
}
#footer{
width: 100%;
height: 100px;
background-image: url("images/bg-header.jpg");
}
Any advice?
Thank-you
Add an inner wrapper to your header HTML
<body>
<div id="header">
<div id="header_inner"><!-- inner div -->
<div id="logo">
</div>
<div id="nav">
</div>
</div><!-- end inner div-->
</div>
<div id="container">
<div id="content">
</div>
</div>
<div id="footer">
</div>
</body>
Then add the same width styling as your container to the wrapper:
#header_inner{
width: 960px;
margin: 0px auto;
}
Then the main content and your header content will align.
Some side notes:
classes are always better than IDs for styling
fixed width are generally not a great idea if you're going for a responsive solution
For Fixed Header or Footer you can use
.header_class {
width: 100vw;
float: left;
position: fixed !important;
top: 0px;
background: url: ('images/img.png') no-repeat;
height: 100%;
}
another better suggestion you can follow facebook header css means upper blue section css (css class name: .fixed_elem, .fixed_always)
I had a little trouble understanding what exactly you were looking to do so I made this example which shows a full page with header and one contained within the middle content area. The main problem I saw was that when you do things like width:100% it doesnt do 100% it is allowed.. but the full width of the parent element. You can use width:inherit to get the max width allowed. Here is the example with a full white header width and one contained using black. Its all in how you structure the parent child DOM relationship structure
<!doctype html>
<html>
<head>
<style>body {margin: 0px;background-color: darkgray;}
header{background-color: white;height:100px;width:100%;}
#header{width: inherit;height: 100px;position: fixed;top: 0px;background-image:url("images/bg-header.jpg");opacity: 0.9;background-color: black;}
#logo {height: 100%;width: 300px;background-color: beige;}
#container {width: 960px;margin: 0px auto;height: 1000px;background-color:gray;}
#footer{width: 100%;height: 100px;background-image: url("images/bg-header.jpg");}
</style>
</head>
<body>
<header><div></div></header>
<div id="container">
<div id="header">
<div id="logo"></div>
<div id="nav"></div>
</div>
<div id="content"></div>
<div id="footer"></div>
</div>
</body>
</html>
The easiest solution is to add a container inside the #header. Create a class .container that has the properties shared by the #container and this container. Also make sure that the container inside the #header gets 100% height.
.container {
width: 960px;
margin: 0 auto;
}
#header .container {
height: 100%;
}
body {
margin: 0;
background-color: darkgray;
}
#header {
width: 100%;
height: 100px;
position: fixed;
top: 0;
background-image: url("http://placehold.it/100x100");
opacity: 0.9;
}
#logo {
height: 100%;
width: 300px;
background-color: beige;
}
#container {
height: 1000px;
background-color: gray;
}
#footer {
height: 100px;
background-image: url("http://placehold.it/100x100");
}
.container {
width: 960px;
margin: 0 auto;
}
#header .container {
height: 100%;
}
<div id="header">
<div class="container">
<div id="logo">
</div>
<div id="nav">
</div>
</div>
</div>
<div id="container" class="container">
<div id="content">
</div>
</div>
<div id="footer">
</div>
Basically you want to have a full width 100px header and footer which are fixed to top 0 and bottom 0. but at the same time you want the content to not exactly roll under the header and footer. I hope I understood the question here.
To achieve that obviously give position fixed to header and footer but now to get your content aligned right, you have to give a margin of the height of header and footer ( 100px)
Here is the code snippet... I have added different colors and some filler content to see the difference.
body {
margin: 0px;
background-color: darkgray;
}
#header,
#footer {
width: 100%;
height: 100px;
position: fixed;
left: 0;
background: blue;
opacity: 0.5;
text-align: center;
color: red;
}
#header {
top: 0;
}
#footer {
bottom: 0;
}
#logo {
height: 100%;
width: 300px;
background-color: beige;
float: left;
}
#nav {
height: 100%;
width: 450px;
background: cyan;
opacity: 0.5;
float: right;
}
#container {
width: 960px;
margin: 100px auto;
height: 1000px;
background-color: orange;
}
<div id="header">
<div id="logo">logo</div>
<div id="nav">nav</div>
</div>
<div id="container">
<div id="content">
content
<br>content
<br>content
<br>content
<br>content
<br>content
<br>content
<br>content
<br>content
<br>content
<br>content
<br>content
<br>
</div>
</div>
<div id="footer">footer</div>
Hope this was what you were looking for.
I've had this problem many times before, where you want full width images, but they're in containers at a fixed width. At any rate there's a few things you can do here. You can add a container class to every section you want in a container; You put a mini-container in divs you want to break the rules, (this also requires taking said div / #header out of the main #container)
#header {
width: 100%;
height: 100px;
position: fixed;
top: 0px;
background-image: url("images/bg-header.jpg");
opacity: 0.9;
}
Than put a div inside of that called content, and set content up like this.
.content {
width: 960px;
margin:0 auto;
display:block;
}
So your markup/html should look like
<div id="header">
<div class="content">
<ul>
<li><a>Home</a></li>
<li><a>Other</a></li>
</ul>
</div>
</div>
There are more options, but these seem to make sense for this issue.
Hope This Helps,

Table Element Not Taking 100% Of Parent Element

I created a sample of the situation in JSFiddle
I updated JSFiddle Here: http://jsfiddle.net/x11joex11/r5spu85z/8/ (this shows in more detail how the sticky footer works so well, just height issue).
I want the table to take up the remaining height, for some reason the height: 100% is not working?
From my tests it appears to be related to min-height: 100%. I need that to make the sticky footer work.
So a solution for me is another way to do the sticky footer, or a way to still give 100% height to the elements within.

}
.footer {

}
.push {
height: 50px;
}
Here is one solution, http://jsfiddle.net/7t4RT/
This question has been asked many times before. I recommend viewing some of the answers already provided here at StackOverflow.
The reason that we're unable to use height: 100% in your example is because no height has defined. The CSS is wondering... well how high is 100%? There are many ways to get our elements to fill their containers in either HTML or CSS. Simply choose one you feel works better for you.
The following is one of many ways to solve this problem.
HTML:
<div class="fill-height">
<p>Filled</p>
</div>
<div class="cant-fill-height">
<p>Not Filled</p>
</div>
CSS:
body {
background-color: #ccc;
}
.fill-height {
background-color: #0ff;
width: 200px;
position: absolute;
top: 0;
bottom: 0;
}
.cant-fill-height {
background-color: #ff0;
width: 200px;
height: 100%;
margin-left: 200px;
}
I found an answer to my problem for now, but it requires the use of display:table which I recall causes other errors down the road, but it does appear to work right now to create the layout I had in mind.
http://jsfiddle.net/x11joex11/r5spu85z/10/
CSS
body,html{margin:0;padding:0;height:100%;}
.wrapper{}
.table{
height:100%;
width:100%;
display:table;
background-color:yellow;
}
.row{display:table-row;}
.cell{display:table-cell;}
.footer{background-color:green;height:50px;}
.header{background-color:red;height:30px;}
.left{background-color:purple;}
.right{background-color:orange;}
HTML
<div class="wrapper table">
<div class="header row">
Header<br/>
Header2
</div>
<div class="content table">
<div class="row">
<div class="cell left">leftt<br/>left2</div>
<div class="cell right">right<br/>right2</div>
</div>
</div>
<div class="footer row">
Footer
<br/>
Footer2
</div>
</div>
An answer not requiring the use of display:table or table tags is preferred.
Notice the sticky footer effect remains.

Set div to remaining height using CSS with unknown height divs above and below

Is it possible to make the wrapper fill the window height (no scrolling) and the center div scrollable without messing around with pixels and javascript?
<div id="wrapper">
<h1>Header</h1>
<div id="center">
<div style="height:1000px">high content</div>
</div>
<div id="footer">Footer</div>
</div>
Basically I want the header to be visible at the top and the footer to be always visible at the bottom and have a scrollable content in the center which occupies the remaning height.
The header, footer and center divs' heights are all unknown (no set px or %, i.e. variable font-size or padding). Is it possible with pure CSS?
2014 UPDATE: The modern way to solve this layout problem is to use the flexbox CSS model. It's supported by all major browsers and IE11+.
2012: The correct way to do this with CSS alone is to use display: table and display: table-row. These are supported by all major browsers, starting with IE8. This is not using tables for display. You'll use divs:
html, body {
height: 100%;
margin: 0;
}
.wrapper {
display: table;
height: 100%;
width: 100%;
background: yellow; /* just to make sure nothing bleeds */
}
.header {
display: table-row;
background: gray;
}
.content {
display: table-row; /* height is dynamic, and will expand... */
height: 100%; /* ...as content is added (won't scroll) */
background: turquoise;
}
.footer {
display: table-row;
background: lightgray;
}
<div class="wrapper">
<div class="header">
<h1>Header</h1>
<p>Header of variable height</p>
</div>
<div class="content">
<h2>Content that expands in height dynamically to adjust for new content</h2>
Content height will initially be the remaining
height in its container (<code>.wrapper</code>).
<!-- p style="font-size: 4000%">Tall content</p -->
</div>
<div class="footer">
<h3>Sticky footer</h3>
<p>Footer of variable height</p>
</div>
</div>
That's it. The divs are wrapped as you'd expect.

Using overflow:auto will let you do this.

So what you are talking about is a sticky footer. I went and did some more research and here is what I have for you.
<div id="wrapper" style="height:100%">
<div id="header" style="float:none;"><h1>Header</h1></div>
<div style="overflow:scroll;float:none;height:auto;">high content</div>
<div id="footer" style="clear:both;position:fixed;bottom:0px;"><h1>Footer</h1></div>
</div>
This will give you a sticky footer. The key is position:fixed and bottom:0px;
Unfortunately this means it also hovers above any content in the scrollview. So far there seems to be only Javascript to figure this out but I will keep looking.
