Below is the CSS code I currently use for <h1> tags to keep them vertically centered within a responsive banner (corrections welcome). What is the simplest way to add an <h2> subtitle within the <h1> title, both within the banner, and additionally have the two headings vertically centered with only a breaking space or similar between them?
.image {
position: relative;
vertical-align: middle;
}
h1 {
font-family: 'Merriweather Sans', sans-serif;
position: absolute;
letter-spacing: 3px;
font-size: 300%;
text-align: center;
bottom: 40%;
width: 100%;
height: 15%;
color: white;
}
If you don't need a specific height on that banner, you might simply use padding:
<header> <!-- with background image -->
<div id="content">
<h1></h1>
<h2></h2>
</div>
</header>
#content {
text-align: center;
padding: 3rem 0;
}
If the banner has a specific height, then you might use transform:
header {
height: 300px;
position: relative;
background-image: url();
}
#content {
position: absolute;
top: 50%;
transform: translateY(-50%);
}
I want to center a div and it's text, in a 100%-screen-width div, which is in a smaller wrapper.
.wrapper {
height: 800px;
width: 900px;
margin: auto;
background-color: #000000;
}
.box-wrapper {
width: 1000%;
position: relative;
left: -500%;
background-color: #FF6600;
}
.box {
background-color: #FF0000;
width: 600px;
position: relative;
left: 50%;
color: #00FF00;
}
span {
text-align: center;
display: block;
}
<div class="wrapper">
Random text for wrapper-div
<div class="box-wrapper">
<div class="box">
<span>ABC</span>
<span>DEF</span>
<span>GHI</span>
</div>
</div>
</div>
This code is kind of working but not perfect.
The red div should be moved a bit to the right, also the way
of doing it is not the best in my opinion.
I want a more robust and responsive solution.
To be more clear, it's for the pink division on the bottom
of this website: http://ndvibes.com
There the code is working 99% of the times and reponsive. But on some computers/screens it's 50% off. So I want a less-hacky (without transform etc) and more standard, robust way of getting that effect.
Wrapper 900px > 100%-screen-width coloured div > Centered text in that coloured div.
How can I achieve this the best as possible?
Thanks!
How about this approach, using absolute positioned pseudo elements. The outer-space div with overflow:hidden is to prevent a horizontal scroll bar appearing. I have added padding-top to the .wrapper just so you can see the snippet running in full screen mode.
body {
margin:0;
}
.outer-space {
overflow: hidden;
padding-top:80px;
}
.wrapper {
height: 800px;
width: 100%;
max-width: 900px;
margin: auto;
background-color: #000000;
}
.box {
background-color: #8904B1;
margin:0 auto;
color: #ffffff;
position: relative;
z-index: 2;
padding:10px 0;
}
.box-wrapper {
position: relative;
width:100%;
max-width: 600px;
margin:0 auto;
}
.box-wrapper:before, .box-wrapper:after {
content:"";
position: absolute;
height:100%;
width:100vw;
background-color: #8904B1;
top: 0;
z-index: 1;
}
.box-wrapper:before {
left:-100%;
}
.box-wrapper:after {
right:-100%;
}
span {
text-align: center;
display: block;
}
<div class="outer-space">
<div class="wrapper">

<div class="box-wrapper">
<div class="box">

To center child element, add the following to the parent wrap will center all child.
display: flex;
align-items: center;
justify-content: center;
If you want 100% screen width, use viewport (100vw) for 100% screen width
viewport
The #viewport CSS at-rule contains a set of nested descriptors in a CSS block that is delimited by curly braces. These descriptors control viewport settings, primarily on mobile devices.
1vw = 1% of viewport width
1vh = 1% of viewport height
1vmin = 1vw or 1vh, whichever is smaller
1vmax = 1vw or 1vh, whichever is larger

I don't really even know what my problem is anymore, but I'll try to explain it as best as I can.
Basically what I have is a two column layout. On the left is the content, which at present only contains a h1 and filler text. On the right is the sidebar which should have a div in it (userinfobox).
The header text of the box is supposed to be outside the box a bit so I have the userinfobox position: relative and the header text position: absolute
Then, under that inside the box, there is a 150x150 image and then some more text below that.
Here's the HTML:
<!-- Main Content -->
<div id="contentwrapper" role="presentation">
<div id="content" role="main">
<h1>Header</h1>
Content link
</div> <!-- content div -->
<!-- Sidebar -->
<div id="sidebar" role="complementary">
<div id="userinfobox">
<p id="header">User Info</p>
<div id="userinfo">
<div id="avatar"><img src="" id="tag" alt="tag" /></div>
<p class="username">Username #</p>
<p id="icons">Icons</p>
<p id="membersonline">Online Members (#)</p></div>
</div> <!-- userinfo div -->
</div> <!-- userinfobox div -->
</div> <!-- sidebar div -->
</div> <!-- contentwrapper div -->
And then the CSS
/* Main Content */
#contentwrapper {
min-height: 400px;
height: 100%;
position: relative;
display: table;
font-size: 1em;
}
#content {
width: 669px;
height: 100%;
padding: 20px;
position: relative;
display: table-cell;
background-color: #F7F8F7;
text-align: left;
}
#content h1 {
margin-bottom: 20px;
font-size: 2.75em;
line-height: 1em;
}
/* Sidebar */
#sidebar {
width: 234px;
height: 100%;
padding: 20px;
position: relative;
color: #0D130D;
background-color: #FDEBCF;
display: table-cell;
text-align: center;
}
#sidebar p#header {
position: absolute;
top: -10px;
font-size: 1.5em;
line-height: 1em;
text-align: left;
overflow: hidden;
}
#sidebar p {
max-width: 214px;
margin: 0 auto;
text-align: center;
overflow: hidden;
}
/* Logged In Sidebar */
#userinfobox {
width: 214px;
max-width: 214px;
padding: 10px;
position: relative;
background-color: #F7F8F7;
}
#avatar, #tag, #userinfo {
margin: 0 auto;
position: relative;
display: block;
outline: 1px solid #000;
overflow: hidden;
}
#avatar, #tag {
width: 150px!important;
height: 150px!important;
}
That should be working, I don't see any reason why it wouldn't be; actually it is working, the sidebar anyway is doing what it's supposed to. But sometimes it pushes down the content (currently the h1 and two words of text), almost to where the bottom of the 150x150 image would be.
I'll attempt to list the conditions that cause it to do this:
It does not work when:
the avatar div is completely empty and the header is position: absolute
the image has a src and the header is position: absolute
But, it does works when (seemingly regardless of absolute positioning of the header):
the src of the image is empty
there is no image, just text, in the avatar div (ie. just text in the entire userinfo div)
the userinfo div is completely empty
I just don't understand how it's affecting something in a completely different div. Every place I've tried to search about this just talked about how absolutely positioned elements inside a relatively positioned element won't affect anything outside and how to use them. Also, this is a fixed width setup, so it's not like the width is changing at all; it is also not based on percent.
Since your #content div is using display:table-cell;, you must also apply vertical-align:top; to prevent your content from centering:
http://jsfiddle.net/R8zAw/3/
#content {
width: 669px;
height: 100%;
padding: 20px;
padding-top: 0;
position: relative;
display: table-cell;
background-color: #F7F8F7;
text-align: left;
border-bottom-left-radius: 5px;
vertical-align: top; /* add this */
}
I have a header bar that is positioned using position:absolute; and I cannot seem to get it to not overlap my content.
Here is the html i'm using for my example:
<div class="ui-page ui-page-active">
<div class="ui-header">
<div class="ui-title ui-title-h1">
Page Title 1
</div>
</div>
<div class="ui-content">
Page Two
</div>
<div class="ui-footer">
<div class="ui-title ui-title-h3">
Page Footer 1
</div>
</div>
</div>
and here is my css
html,body {
height: 100%;
width: 100%;
margin: 0;
padding: 0;
}
.ui-page {
background-color: #bbb;
height: 100%;
width: 100%;
display: block;
position: relative;
}
.ui-page-inactive {
display: none;
}
.ui-page-active {
display: block;
}
.ui-header {
position: absolute;
top: 0;
background-color: #000;
width: 100%;
display: inline-block;
}
.ui-content {
}
.ui-footer {
position: absolute;
bottom: 0;
background-color: #000;
width: 100%;
display: inline-block;
}
.ui-title {
text-align: center;
color: #fff;
padding: 4px;
line-height: 150%;
}
.ui-title-h1 {
font-size: 1.5em;
font-weight: 900;
}
My end goal is to have a header bar always at the top, a footer bar always at the bottom and for the content to fill the centre. The content div does not actually need to fill 100%, I just don't want it to be blocked by either the header or footer.
An easy way would be to have either padding-top or margin-top (I'm not sure which) on .ui-content set to the height of your header, that would push .ui-content down so there isn't overlap.
If the header and footer are a fixed-height (like, for example "80px") then you can make the content absolute with the top-and-bottom margins (position:absolute;overflow-y:scroll;top:80px;bottom:80px;) and make the header and footer fixed (position:fixed;height:80px;top:0;left:0;right:0;overflow:hidden; for the header and position:fixed;height:80px;bottom:0;left:0;right:0;overflow:hidden; for the footer)
Something like that might work.
This question already has answers here:
How can I horizontally center an element?
(133 answers)
Closed 4 years ago.
I have a div tag with width set to 800 pixels. When the browser width is greater than 800 pixels, it shouldn't stretch the div, but it should bring it to the middle of the page.
<body>
<div style="width:800px; margin:0 auto;">
centered content
</div>
</body>
position: absolute and then top:50% and left:50% places the top edge at the vertical center of the screen, and the left edge at the horizontal center, then by adding margin-top to the negative of the height of the div, i.e., -100 shifts it above by 100 and similarly for margin-left. This gets the div exactly in the center of the page.
#outPopUp {
position: absolute;
width: 300px;
height: 200px;
z-index: 15;
top: 50%;
left: 50%;
margin: -100px 0 0 -150px;
background: red;
}
<div id="outPopUp"></div>
Flexbox solution is the way to go in/from 2015. justify-content: center is used for the parent element to align the content to the center of it.
HTML
<div class="container">
<div class="center">Center</div>
</div>
CSS
.container {
display: flex;
justify-content: center;
}
Output
.container {
display: flex;
justify-content: center;
}
.center {
width: 400px;
padding: 10px;
background: #5F85DB;
color: #fff;
font-weight: bold;
font-family: Tahoma;
}
<div class="container">
<div class="center">Centered div with left aligned text.</div>
</div>
Do you mean that you want to center it vertically or horizontally? You said you specified the height to 800 pixels, and wanted the div not to stretch when the width was greater than that...
To center horizontally, you can use the margin: auto; attribute in CSS. Also, you'll have to make sure that the body and html elements don't have any margin or padding:
html, body { margin: 0; padding: 0; }
#centeredDiv { margin-right: auto; margin-left: auto; width: 800px; }
<div></div>
div {
display: table;
margin-right: auto;
margin-left: auto;
}
To make it also work correctly in Internet Explorer 6 you have to do it as follows:
HTML
<body>
<div class="centered">
centered content
</div>
</body>
CSS
body {
margin: 0;
padding: 0;
text-align: center; /* !!! */
}
.centered {
margin: 0 auto;
text-align: left;
width: 800px;
}
Div centered vertically and horizontally inside the parent without fixing the content size
Here on this page is a nice overview with several solutions, too much code to share here, but it shows what is possible...
Personally I like this solution with the famous transform translate -50% trick the most. It works well for both fixed (% or px) and undefined height and width of your element.
The code is as simple as:
HTML:
<div class="center"><div>
CSS:
.center {
position: absolute;
left: 50%;
top: 50%;
-moz-transform: translate(-50%, -50%); /* Firefox */
-ms-transform: translate(-50%, -50%); /* IE 9 */
-webkit-transform: translate(-50%, -50%); /* Safari and Chrome*/
-o-transform: translate(-50%, -50%); /* Opera */
transform: translate(-50%, -50%);
/* optional size in px or %: */
width: 100px;
height: 100px;
}
Here a fiddle that shows that it works
You can also use it like this:
<div style="width: 60%; margin: 0px auto;">
Your contents here...
</div>
Simply use the center tag just after the body tag, and end the center tag just before body ends:
<body>
<center>
... Your code here ...
</center>
</body>
This worked for me with all the browsers I have tried.
This can be easily achieved via flex container.
.container{
width: 100%;
display: flex;
height: 100vh;
justify-content: center;
}
.item{
align-self: center;
}
Preview Link
Add this class to the div you want centered (which should have a set width):
.marginAutoLR
{
margin-right:auto;
margin-left:auto;
}
Or, add the margin stuff to your div class, like this:
.divClass
{
width:300px;
margin-right:auto;
margin-left:auto;
}
Use the CSS flex property: http://jsfiddle.net/cytr/j7SEa/6/show/
body { /* Centered */
display: box;
flex-align: center;
flex-pack: center;
}
Some other pre-existing setups from older code that will prevent div page centering L&R are:
Other classes hidden in external stylesheet links.
Other classes embedded in something like an img (like for older external CSS print format controls).
Legend code with IDs and/or CLASSES will conflict with a named div class.
Centering without specifying div width:
body {
text-align: center;
}
body * {
text-align: initial;
}
body div {
display: inline-block;
}
This is something like <center> tag does, except:
all direct inline childs elements (eg. <h1>) of <center> will also positioned to center
inline-block element can have different size (comapred to display:block setting) according to browser defaults
Use the below code for centering the div box:
.box-content{
margin: auto;
top: 0;
right: 0;
bottom: 0;
left: 0;
position: absolute;
width: 800px;
height: 100px;
background-color: green;
}
<div class="box-content">
</div>
If you have some regular content, and not only one line of text, the only possible reason I know is to calculate margin.
Here is an example:
HTML
<div id="supercontainer">
<div id="middlecontainer">
<div class="common" id="first">first</div>
<div id="container">
<div class="common" id="second">second</div>
<div class="common" id="third">third</div>
</div>
</div>
</div>
CSS
body {
margin: 0;
padding: 0;
}
.common {
border: 1px solid black;
}
#supercontainer {
width: 1200px;
background: aqua;
float: left;
}
#middlecontainer {
float: left;
width: 104px;
margin: 0 549px;
}
#container {
float: left;
}
#first {
background: red;
height: 102px;
width: 50px;
float: left;
}
#second {
background: green;
height: 50px;
width: 50px;
}
#third {
background: yellow;
height: 50px;
width: 50px;
}
So, #supercontainer is your "whole page" and its width is 1200px.
#middlecontainer is div with content of your site; it's width 102px. In case the width of content is known, you need to divide the page's size to 2, and subtract half of content's width from the result:
1200 / 2 - (102 / 2) = 549;
Yes, I'm also seeing that this is der grosse fail of CSS.
.middle {
margin:0 auto;
text-align: center;
}
/* it brings div to center */
parent {
position: relative;
}
child {
position: absolute;
left: 50%;
transform: translateX(-50%);
}
<parent>
<child>
</child>
</parent>
Use justify-content and align-items to horizontally and vertically align a div

.container {
display: table-cell;
vertical-align: middle;
}
.container .box {

height: 100px;
background: red;
margin: 0 auto;
}
http://jsfiddle.net/NPV2E/
"width:100%" for the "body" tag is only for an example. In a real project you may remove this property.
Simple http://jsfiddle.net/8pd4qx5r/
html {
display: table;
height: 100%;
width: 100%;
}
body {
display: table-cell;
vertical-align: middle;
}
.content {
margin: 0 auto;
width: 260px;
text-align: center;
background: pink;
}
This also works in Internet Explorer, but auto margins do not.
.centered {
position: absolute;
display: inline-block;
left: -500px;
width: 1000px;
margin: 0 50%;
}
If your center content is deep inside other divs then only margin can save you. Nothing else. I face it always when not using a framework like Bootstrap.
In my case, the phone screen size is unknown, and here is what I did.
HTML
<div class="loadingImg"></div>
CSS
.loadingImg{
position: fixed;
top: 0px;
left: 0px;
z-index: 9999999;
border: 0;
background: url('../images/loading.gif') no-repeat center;
background-size: 50px 50px;
display: block;
margin: 0 auto;
-webkit-border-radius: 50px;
border-radius: 50px;
}
JavaScript (before you need to show this DIV)
$(".loadingImg").css("height",$(document).height());
$(".loadingImg").css("width",$(document).width());
$(".loadingImg").show();
<body>
<div style=" display: table; margin: 250 auto;">
In center
</div>
</body>
If you want to change the vertical position, change the value of 250 and you can arrange the content as per your need. There is no need to give the width and other parameters.
For some reason, none of the previous answers worked for me really. This is what worked for me and it works across browsers as well:
.center {
text-align: center;
height: 100%;
/* Safari, Opera, and Chrome */
display: -webkit-box;
-webkit-box-pack: center;
-webkit-box-align: center;
/* Firefox */
display: -moz-box;
-moz-box-pack: center;
-moz-box-align: center;
/* Internet Explorer 10 */
display: -ms-flexbox;
-ms-flex-pack: center;
-ms-flex-align: center;
}
Get the width of the screen.
Then make margin left 25%
Make margin right 25%
In this way the content of your container will sit in the middle.
Example: suppose that container width = 800px;
<div class='container' width='device-width' id='updatedContent'>
<p id='myContent'></p>
<contents></contents>
<contents></contents>
</div>
if ($("#myContent").parent === $("updatedContent"))
{
$("#myContent").css({
'left': '-(device-width/0.25)px';
'right': '-(device-width/0.225)px';
});
}
