I have a simple layout that I've created with CSS grid consisting of a main element and a sidebar (please see snippet). Inside the sidebar, I have a child element that I would like to go full-width (i.e. ignore the padding around the layout container) on mobile devices.
The .full-width element does go full-width, but apparently what happens is it gets the whole grid to be 100vw, which makes main and aside overflow .container (the grey element). How can I keep it full-width and keep main and aside within the boundaries of .container? Another requirement is that the full-width element remains in the flow of the document (so no fixed or absolute positioning).
.page {
background: pink;
padding: 30px;
}
.container {
display: grid;
grid-template-areas: "aside" "main";
background: grey;
padding: 60px 0;
}
aside {
background: yellow;
}
main {
background: green;
}
.full-width {
width: 100vw;
margin-left: -30px;
background: red;
}
<div class="page">
<div class="container">
<main>
<p>I'm the main content</p>
</main>
<aside>
<p>I'm the sidebar</p>
<div class="full-width">
<p>I'm the full width element</p>
</div>
</aside>
</div>
</div>
First and easy solution is to set the columns to be 100% to avoid the overflow:
.page {
background: pink;
padding: 30px;
}
.container {
display: grid;
grid-template-areas: "aside" "main";
grid-template-columns: 100%;
background: grey;
padding: 60px 0;
}
aside {
background: yellow;
}
main {
background: green;
}
.full-width {
width: 100vw;
margin-left: -30px;
background: red;
}
body {
margin:0;
}
<div class="page">
<div class="container">
<main>
<p>I'm the main content</p>
</main>
<aside>
<p>I'm the sidebar</p>
<div class="full-width">
<p>I'm the full width element</p>
</div>
</aside>
</div>
</div>
Or simply use negative margin on both sides to have the full width you want:
.page {
background: pink;
padding: 30px;
}
.container {
display: grid;
grid-template-areas: "aside" "main";
background: grey;
padding: 60px 0;
}
aside {
background: yellow;
}
main {
background: green;
}
.full-width {
margin-left: -30px;
margin-right: -30px;
background: red;
}
body {
margin:0;
}
<div class="page">
<div class="container">
<main>
<p>I'm the main content</p>
</main>
<aside>
<p>I'm the sidebar</p>
<div class="full-width">
<p>I'm the full width element</p>
</div>
</aside>
</div>
</div>

I'm trying to achieve the following:
I was able to replicate the image but only if my div is not floating in the page (without the margin applied and without the position: absolute), otherwise I can't see the green rectangle.
My HTML structure is the following:
<div class="app">
<div class="interface">
<div class="view">
<div class="body">
<div class="top">
Top content
</div>
<div class="middle">
Middle content
</div>
<div class="bottom">
Bottom content
</div>
</div>
</div>
</div>
</div>
In the .interface CSS I have the following:
.interface
{
position: absolute;
top: 15%;
}
With this CSS I'm unable to see the green rectangle. If I remove the position: absolute (and therefore the top: 15% stops applying) I'm able to see the green rectangle.
You can see the issue in this JSFiddle: https://jsfiddle.net/v9euwdz3/
So, how do I manage to have the DIV showing at a certain level (margin from top) and without compromise my HTML structure?
Here is what you're trying to achieve using flex:
.body {
display: flex;
flex-direction: column;
background-color: blue;
justify-content: space-between;
height: 100vh;
}
.navetc {
background-color: white;
height: 15vh;
}
.top {
background-color: green;
height: 60px;
}
.middle {
background-color: yellow;
flex-grow: 1;
}
.bottom {
background-color: red;
height: 50px;
}
<div class="app">
<div class="interface">
<div class="view">
<div class="body">
<div class="navetc">
SPACE
</div>
<div class="top">
Top content
</div>
<div class="middle">
Middle content
</div>
<div class="bottom">
Bottom content
</div>
</div>
</div>
</div>
</div>
You could also use margin-top: 15%; instead of a placeholder div
.body {
display: flex;
flex-direction: column;
background-color: blue;
justify-content: space-between;
height: 100vh;
}
.top {
margin-top: 15vh;
background-color: green;
height: 60px;
}
.middle {
background-color: yellow;
flex-grow: 1;
}
.bottom {
background-color: red;
height: 50px;
}
<div class="app">
<div class="interface">
<div class="view">
<div class="body">
<div class="top">
Top content
</div>
<div class="middle">
Middle content
</div>
<div class="bottom">
Bottom content
</div>
</div>
</div>
</div>
</div>
(I used vh instead of % to get it to show up correctly in this code snippet)
as we know the content that have height which is 100% means is 100% of its parent and while the height of the parent is not defined will cause an error that's what you was stuck with you set the with of body to 100% but was not right you would set it to 100vh to fit the screen if you are on computer and the other mistakes that I found was in your calculation where you used to subtract the measurement which is in parcentages from the one in pixels height: calc(100% - 150px); and the others where simple mistakes
html,
body {
height: 100vh;
}
.app {
position: relative;
height: 100%;
display: flex;
}
.interface {
position: absolute;
height: 100%;
top: 15%;
}
.view {
position: fixed;
height: 100%;
background-color: #ccc;
width: 350px;
}
.body {
position: relative;
height: 100%;
}
.body .top {
height: 15%;
border: 1px solid #000;
}
.body .middle {
height: 60%;
border: 1px solid red;
}
.body .bottom {
height: 20%;
border: 1px solid green;
}
<div class="app">
<div class="interface">
<div class="view">
<div class="body">
<div class="top">
Top content
</div>
<div class="middle">
Middle content
</div>
<div class="bottom">
Bottom content
</div>
</div>
</div>
</div>
</div>
to see the result in the snippet you should observe it in full page and also when you see the result through jsfiddle there at the result section there is bar downward which hide some part of footer
I have a JS Fiddle here.
https://jsfiddle.net/h3c6jqfy/
Basically, i am trying to make a UI that has a sticky header and footer. The middle content will have three columns. Each columns will have DIVs in them. These DIVs should have 100% height and not be cut off from the footer. Within the DIV, they will have scrollable divs.
The very basic layout I created has this in it...
d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>this is the end!!
The part where it says this is the end!! is never reached.
You can use flexbox without the need to calculate heights;
* {
margin: 0;
padding: 0;
box-sizing: border-box;
}
::before,
::after {
box-sizing: inherit;
}
body {
display: flex;
flex-direction: column;
height: 100vh;
}
header {
height: 75px;
background: red;
}
main {
flex: 1;
background: lightgreen;
display: flex;
}
.scrolly {
flex: 1 0 33%;
overflow-y: auto;
}
.content {
height: 1000px;
}
footer {
height: 50px;
background: blue;
}
<header></header>
<main>
<div class="scrolly">
<div class="content"></div>
</div>
<div class="scrolly">
<div class="content"></div>
</div>
</div>
<div class="scrolly">
<div class="content"></div>
</div>
</div>
</main>
<footer></footer>
NOTE: See Fiddle in Full Screen
You can try using flexbox instead of defining every unit, calculate the height to avoid using the space where the footer sits, and let the children div inherit its height
<style>
body, head {overflow: hidden;}
#header,#footer,#content { position:absolute; right:0;left:0;}
#header{
height:100px; top:0; background: #4A4A4A;
}
#footer{
height:100px; bottom:0; background: #4A4A4A;
}
#content{
top:100px;
height: calc(100% - 100px);
background:#fff;
display: flex;
align-items: stretch;
}
</style>
<div>
<div id="header">HEADER</div>
<div id="content">
<div style="background-color: #ff0000; min-width: 33%; height: inherit; overflow-y: scroll;">
<div style="background-color: blue;min-height: inherit;max-width: 99%;padding: 20px 40px;">
<div style="overflow: auto; max-height: inherit; padding: 10px;">
<br>d<br>d<br>d<br>d<br>d<br>d<br>d
<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>

d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>d<br>

<br>d<br>this is the end!!
</div>
</div>

<div style="background-color: #ff0000; min-height: 100%; min-width: 33%; max-width: 33%;float: left;">

<div style="background-color: #ff0000; min-height: 100%; min-width: 33%; max-width: 33%;float: left;">

<div id="footer">FOOTER</div>
</div>
This image shows what I am trying to do.
Basically, I have a header and footer inside the body. I have a div1 inside a header which has a size that can vary. I want to align div2, which is inside the footer, so that its right border is matches the right border of div1.
The following HTML can explain the structure.
<body>
<div id="header">
<div id="div1">
</div>
</div>
<div id="footer">
<div id="div2">
</div>
</div>
This would be the css.
#div1 {
overflow: auto;
display: grid;
float: start;
}
#div2 {
width: 20px;
// ??????
}
There's no float: start. You just be better off having a common container, as how it is in Bootstrap and other frameworks to "contain" your code. So your page might be rendered well this way:
body {
font-family: 'Segoe UI';
background: #ffa500;
}
#header {
background-color: #fcc;
padding: 10px;
}
#footer {
background-color: #f99;
padding: 10px;
}
.container {
max-width: 65%;
overflow: hidden;
}
#div1 {
padding: 10px;
background-color: #99f;
}
#div2 {
padding: 10px;
background-color: #ccf;
float: right;
width: 50%;
}
<div id="header">
<div class="container">
<div id="div1">
div1
</div>
</div>
</div>
<div id="footer">
<div class="container">
<div id="div2">
div2
</div>
</div>
</div>
Preview
I have this html structure with the section being basically my main content:
<html>
<head>
<body>
<nav id="primary">
<nav id="secondary">
<section id="maincontainer">
<div id="main">...</div>
<footer>
<div class="footer-inner">...</div>
</footer>
</section>
</body>
</html>
Within the div with id 'main' there is content being dynamically loaded via ajax, so the height can vary.
I need the footer to always be at the bottom, even for sub pages with barely any content not filling the page height.
Currently I have position absolute for the footer, which does not work for the dynamic content pages, the footer is stuck in the middle of the content (original window height position).
Is there a way to do this css only?
Thank you!
Do this
<footer style="position: fixed; bottom: 0; width: 100%;"> </footer>
You can also read about flex it is supported by all modern browsers
Update:
I read about flex and tried it. It worked for me. Hope it does the same for you. Here is how I implemented.Here main is not the ID it is the <main> div
body {
margin: 0;
display: flex;
min-height: 100vh;
flex-direction: column;
}
main {
display: block;
flex: 1 0 auto;
}
Here you can read more about flex https://css-tricks.com/snippets/css/a-guide-to-flexbox/
Do keep in mind it is not supported by older versions of IE.
Using bottom:0; position:fixed for footer style You can easily achieve what you want.
body,html{ margin:0px; padding:0px;height:100%}
.page-wrap {
min-height: 100%;
/* equal to footer height */
margin-bottom: -50px;
}
.page-wrap:after {
content: "";
display: block;
}
.site-footer, .page-wrap:after {
position: fixed;
bottom: 0;
width: 100%;
height:50px;
}
.site-footer {
background: red;
}
<div class="page-wrap">
<nav id="primary"></nav>
<nav id="secondary"></nav>
<section id="maincontainer">
<div id="main">...</div>
<footer class="site-footer">
<div class="footer-inner">Footer</div>
</footer>
</section>
</div>
Hope it helps.
Method 1: Using calc() property by wrapping the header and content in one div.
body,html{ margin:0px; padding:0px;height:100%}
.wrapper{height:calc(100% - 50px);}
footer{ height:50px; background:red;}
<div class="wrapper">
<nav id="primary"></nav>
<nav id="secondary"></nav>
<section id="maincontainer">
<div id="main">...</div>
</section>
</div>
<footer>
<div class="footer-inner">Footer</div>
</footer>
Method 2: By using -ve height of footer with the wrapper element.
body,html{ margin:0px; padding:0px;height:100%}
.page-wrap {
min-height: 100%;
/* equal to footer height */
margin-bottom: -50px;
}
.page-wrap:after {
content: "";
display: block;
}
.site-footer, .page-wrap:after {
height: 50px;
}
.site-footer {
background: red;
}
<div class="page-wrap">
<nav id="primary"></nav>
<nav id="secondary"></nav>
<section id="maincontainer">
<div id="main">...</div>
</section>
</div>
<footer class="site-footer">
<div class="footer-inner">Footer</div>
</footer>
EDIT
Method 3: using same structure and calc().
body,
html {
margin: 0px;
padding: 0px;
height: 100%
}
#primary {
height: 50px;
background: green;
width: 100%;
}
#secondary {
height: 50px;
background: yellow;
width: 100%;
}
#maincontainer {
width: 100%;
height: calc(100% - 130px);
}
#main {
height: 100%;
}
footer {
background: red;
height: 30px;
}
<nav id="primary">Nav 1</nav>
<nav id="secondary">Nav 2</nav>
<section id="maincontainer">
<div id="main">...</div>
<footer>
<div class="footer-inner">...</div>
</footer>
</section>
I am trying to use a flexbox approach to create a layout that will resize the header width and content dimensions when a window is resized, but maintain the sidebar dimensions.
I found the following example from this Flexbox Approach to get me started, and it works as desired for the content div itself. But after looking it over, I'm unsure how to make it work as described with a fixed width, 100% height sidebar.
CSS from example:
<style>
html, body {
height: 100%;
margin: 0
}
.box {
display: flex;
flex-flow: column;
height: 100%;
}
.box .row {
border: 1px dotted grey;
}
.box .row.header {
flex: 0 1 auto; /* The above is shorthand for: flex-grow: 0, flex-shrink: 1, flex-basis: auto */ }
.box .row.content {
flex: 1 1 auto;
}
.box .row.footer {
flex: 0 1 40px;
}
</style>
HTML from example:
<div class="row header">
<p><b>header</b> <br /> <br />(sized to content)</p>
</div> <div class="row content">
<p> <b>content</b> (fills remaining space) </p>
</div>
<div class="row footer">
<p><b>footer</b> (fixed height)</p>
</div>
</div>
The following codepen example gave me the information I needed to get my layout working:
http://codepen.io/JosephSilber/pen/HqgAz
CSS:
.header {
height: 50px;
}
.body {
position: absolute;
top: 50px;
right: 0;
bottom: 0;
left: 0;
display: flex;
}
.sidebar {
width: 140px;
}
.main {
flex: 1;
display: flex;
flex-direction: column;
}
.content {
flex: 1;
display: flex;
overflow: auto;
}
.box {
min-height: -webkit-min-content;
display: flex;
}
.column {
padding: 20px;
border-right: 1px solid #999;
}
.column > div {
height: 2000px;
background: red;
}
.column:nth-child(2) > div {
height: auto;
}
/* All of these are just for this demo's design. */
body {
font-family: sans-serif;
font-size: 20px;
line-height: 50px;
text-transform: uppercase;
font-weight: bold;
}
.header {
text-align: center;
color: #fff;
background: #444;
}
.sidebar {
background: #666;
padding: 4px 20px;
color: #fff;
}
.page-header {
padding: 6px 20px;
background: #004141;
color: #fff;
font-size: .8em;
}
.content {
background: #ddd;
}
HTML:
<div class="header">Main header</div>
<div class="body">
Move this: <div class="sidebar">Sidebar</div>
<div class="main">
<div class="page-header">Page Header. Content columns are below.</div>
<div class="content">
<div class="box">
<div class="column">
<div>Column 1</div>
</div>
<div class="column">
<div>Column 1</div>
</div>
<div class="column">
<div>Column 1</div>
</div>
</div>
</div>
</div>
To here: <div class="sidebar">Sidebar</div>
</div>
To get the sidebar on the right side, I simply moved <div class="sidebar">Sidebar</div>to just above the closing div tag for the .body class.
