i would like to center a popup div how can i do that browser friendly????
this is the original a bit to the left.
<div class="popLayerWrapper">
<div id="addBookmarksLayer" class="popLayer" style="left:260px; padding:30px;">
<div class="closeLayer" >close</div>
<div class="layerContent"></div>
</div>
</div>
Not sure I understand which part you want to center, but assuming the whole thing:
.popLayerWrapper {
position: absolute;
width: 40%; /* could be anything */
left: 50%;
margin-left: -20%; /* half of width */
height: 40%; /* again, could be anything */
top: 50%;
margin-top: -20%; /* half of height */
}
I use this code to center an element in the center of the window viewport:
html {
display: table;
table-layout: fixed;
width: 100%;
height: 100%;
}
body {
display: table-cell;
width: 100%;
height: 100%;
vertical-align: middle;
margin:0;
}
#center {
margin: auto;
}
You will find a full example at this link (Bredele CSS bundle). I think it should work for your popup.

I'm using Swipe.js to create a page with several screens. Swipe requires a structure of 3 nested divs, with some style defined. I want to position an element 70% towards the bottom of one of the screens, but I'm finding that its Y position remains at the top when defined as a percentage. My guess is that the height of the containing div is somehow still 0, though I have set all min-height properties to 100%.
I'm testing on Chrome in desktop, for now. My stylesheet:
/* required by swipe.js */
.swipe {
overflow: hidden;
position: relative;
min-height: 100%; /* added this everywhere I could just in case */
}
.swipe-wrap {
overflow: hidden;
position: relative;
min-height: 100%;
}
.swipe-wrap > div {
float: left;
width: 100%;
min-height: 100%;
position: relative;
}
.page {
min-height: 100%;
}
html,body {
height: 100%;
margin: 0px;
padding: 0px;
}
/* element I want to position */
.myElement {
position: relative;
width: 200px;
top: 70%;
left: 50%;
transform: translate(-50%, -50%);
}
Body:
<div id="slider" class="swipe">
<div class="swipe-wrap">
<div class="page">
<div class="myElement">
<h1>I should be more than halfway down.</h1>
</div>
</div>
</div>
</div>
The result is that the inner div is centred horizontally, but vertically it's at the top (in fact, cut off because of the transform offset).
I have tried using flex and align-items: center. That does work. I'm not sure if I can use flex to define arbitrary relative positions, though.
Please check below example
.swipe {
overflow: hidden;
position: relative;
height: 100%;
}
.swipe-wrap {
overflow: hidden;
position: relative;
height: 100%;
}
.swipe-wrap > .page {
display: table;
width: 100%;
height: 100%;
table-layout: fixed;
text-align: center;
}
.myElement{
display: table-cell;
vertical-align: middle;
}
.page {
min-height: 100%;
}
html,body {
height: 100%;
margin: 0px;
padding: 0px;
}
<div id="slider" class="swipe">
<div class="swipe-wrap">
<div class="page">
<div class="myElement">
<h1>I should be more than halfway down.</h1>
</div>
</div>
</div>
</div>
I am trying to center the ajax loader. But no luck. Loader appears on right corner of the screen. Appreciate assistance. Below is the code
div.amshopby-overlay {
background-color: #fafafa;
height: 100%;
left: 0;
opacity: 0.5;
filter: alpha(opacity = 50);
position: absolute;
top: 0;
width: 100%;
z-index: 555;
}
div.amshopby-overlay img {
top: 100px;
left: 45%;
display: block;
position: absolute;
}
div.amshopby-overlay div {
margin: 0 auto;
display: block;
width: 300px;
height: 200px;
background: url('../images/amshopby-overlay.gif') 50% 50% no-repeat;
}
Try this css.
<div class="container">
<img src="loader.gif" class="loader">
</div>
CSS
.container{position:relative; height:300px;width:300px;}
.loader{position:absolute;left:0;right:0;top:0;bottom:0;margin:auto}
A solution I like to do when whatever I'm centering is just an image is to do it with the css background property:
HTML
<div id="container"></div>
CSS
#container.loader{
background:url('loader.gif') center center no-repeat;
}
Now in your javascript, add the class loader when you make the ajax request and remove the class on complete.
So I assume the div inside the amshopby-overlay contains your loader image. Give it a try:
div.amshopby-overlay div {
display: block;
width: 300px;
height: 200px;
background: url('../images/amshopby-overlay.gif') 50% 50% no-repeat;
/* Add this */
position: absolute;
top: 50%;
margin-top: -100px;
left: 50%;
margin-left: 150px;
}
Basically, top and left will push the div 50% from top and left. And we will add -50% of the div width and height value to center in vertically and horizontally. Give it a try. Hope it helps.
"margin: auto" should give you the centering style you want. CSS details below.
HTML
<div class="container">
<img src="http://placehold.it/150x150" class="loader">
</div>
CSS
.container {
/*Absolute positioning will now be relative to this tag*/
position:relative;
/*Arbitrary Height*/
height:300px;
width:300px;
/*border to show container*/
border: 1px solid;
}
.loader {
/*Allow top, left, right, bottom
to be set relative to container*/
position: absolute;
/*Set edges of tag so margin auto knows the max boundry*/
top: 0px;
left: 0px;
right: 0px;
bottom: 0px;
/*Allows the use of margin auto*/
display: block;
/*Horizontally and vertically centered
(Display block will fill remaining margin space equally)*/
margin: auto;
}

How to center div in the page? (Height & Width)?
(2 answers)
Closed 8 years ago.
I mean, if i have a div, with 200px of height and 200px of width, and i want to align it vertically (i can align it horizontaly with "margin: auto", but, is there a way to align it vertically without knowking the height of the screen?
Thanks and sory for my english, it's not my native language
edit: height of the screen
Centering things with table display is pretty handy... Take a look at this this:
http://jsfiddle.net/F9J4B/
Note that this is not "layouting with table"... It's just three divs that are using the table's display rules. No semantics rules are broken =)
HTML
<div class="table">
<div class="tr">
<div class="td">
<p>Hello! I'm a DOM element. <br>I can be whatever size i want, and still still be in the center of things.</p>
</div>
</div>
</div>
CSS
body,
html {
height:100%
}
.table {
width: 100%;
height: 100%;
display: table;
background-color: #eee;
}
.tr {
display: table-row;
}
.td {
display: table-cell;
text-align: center;
vertical-align: middle;
}
Here's an example, FIDDLE
div {
position: absolute;
width: 200px;
height: 200px;
top: 50%;
left: 50%;
margin-top: -100px;
margin-left: -100px;
}
Centering a box inside another box:
div{
position: absolute;
left: 50%;
top: 50%;
transform: translate(-50%, -50%);
}
regardless of the size of the boxes.
The outer box may need position: relative; for the inner boxes' positioning to work.
The Media Query handles the image when the screen gets too small.
.vertcenterdiv {
position: absolute;
background-image: url('http://upload.wikimedia.org/wikipedia/commons/2/27/Square_200x200.svg');
background-position: center center;
background-repeat: no-repeat;
background-size: 100% auto;
height: 200px;
width: 200px;
top: 50%;
left: 50%;
margin-top: -100px;
margin-left: -100px;
}
#media (max-width: 200px) {
.vertcenterdiv {
position: absolute;
height: 100%;
width: 100%;
top: 0;
left: 0;
margin-top: 0;
margin-left: 0;
}
}
What I am trying to is have a header image centered on the top with a different color background on either side, dynamically filling the rest of the page. The structure would look like this:
<div id="Header_Container">
<div id="Header_Left"></div>
<div id="Header_Center"></div>
<div id="Header_Right"></div>
</div>
The Header_Center is of 960px and the Header_Left and Header_Right should fill either side of the image to the edge of the page and change width as the page width changes.
I can not get the CSS to work properly.
I assume you want those 3 divs to fill each with different content, the outsides filled fluidly or multiline. Otherwise the answer could be much 1) more simple. I also assume that the center div defines the total height of the header.
Given these two assupmtions, still a few different scenarios are thinkable of which I will give 4 examples from which you can choose the best fitting solution.
The HTML is exactly yours.
The CSS looks like:
#Header_Container {
width: 100%;
position: relative;
}
#Header_Left {
position: absolute;
left: 0;
right: 50%;
margin-right: 480px;
}
#Header_Right {
position: absolute;
left: 50%;
right: 0;
margin-left: 480px;
top: 0;
}
#Header_Center {
width: 960px;
position: relative;
left: 50%;
margin-left: -480px;
}
Now, you could change behaviour of left and right with a few extra styles:
height: 100%;
overflow: hidden;
See demonstration fiddle.
1) When the sides may be partially invisible outside the browser window (in case which you would align content in de left div to the right, and vise versa), then I suggest the solution in this fiddle demo which does not require absolute positioning at all so that any content below the header is properly cleared in all circumstances.
You must fix it using padding and box model + position : relative - it can be done without HTML Change
<div id="Header_Container">
<div id="Header_Left"></div>
<div id="Header_Right"></div>
<div id="Header_Center"></div>
</div>
And CSS ( 100px is for example )
#Header_Container{ overflow: hidden; height: 100px; }
#Header_Container *{ box-sizing: border-box; height: 100%; }
#Header_Left{ width: 50%; padding-right: 480px; }
#Header_Right{ margin-left: 50%; width: 50%; padding-left: 480px; position: relative; top: -100% };
#Header_Center{ margin: 0 auto; width: 960px; position: relative; top: -200%; }
Example is here http://jsfiddle.net/ZAALB/2/
EDITed incorrect example
If I got you right then this might be a possible solution.
#container {
width: 100%;
height: 150px;
}
#left {
position: absolute;
left: 0;
width: 50%;
height: 150px;
background-color: #FF0000;
}
#right {
position: absolute;
right: 0;
width: 50%;
height: 150px;
background-color: #0000FF;
}
#center {
position: absolute;
left: 50%;
margin-left: -480px;
width: 960px;
height: 150px;
background-color: #888888;
}
#left basically says that the element will be positioned absolute and attached to the left side with a width of 50%. Same applies to #right just for the right side.
#center positions the element absolute pushed 50% to the left and then with a negative margin of width/2 which in your case would be 480px to position it in the center.
The order of the elements in the HTML is important for this hack.
<div id="container">
<div id="left"></div>
<div id="right"></div>
<div id="center"></div>
</div>
The #center DIV must be the last element if you don't want to work with z-indexes.
Here's a fiddle to test it.
HTML:
<div id="Header_Container">
<div class="Header_Side" id="Header_Left"></div>
<div class="Header_Side" id="Header_Right"></div>
<div id="Header_Center"></div>
</div>
CSS:
#Header_Container {
position: relative;
width: 100%;
}
#Header_Container > div {
height: 158px; /* height of the image */
}
.Header_Side {
position: absolute;
width: 50%;
}
#Header_Left {
left: 0;
background-color: blue;
}
#Header_Right {
left: 50%;
background-color: green;
}
#Header_Center {
position: relative;
width: 158px; /* width of the image */
margin: 0 auto;
background-image: url('...');
}
Also see this example.
This works, but you need to change your HTML: http://jsfiddle.net/gG7r7/1/
HTML
<div id="header_background_container">
<div id="header_left"></div>
<div id="header_right"></div>
</div>
<div id="header_content_container">
<div id="header_content"><p>Content goes here</p></div>
</div>
CSS
#header_content_container {
position:absolute;
z-index:1;
width: 100%;
height: 100%;
}
#header_content {
width: 960px;
margin: 0 auto;
background: red;
height: 100%;
}
#header_left {
background: white;
width: 50%;
height: 100%;
position: absolute;
z-index: 0;
}
#header_right {
background: black;
width: 50%;
height: 100%;
position: absolute;
z-index: 0;
}
I have an iframe and a div inside a container. The two of them need to be vertically centered. After reading a few posts on tables to center, I gave it a try but to no avail. The iframe continues to stick to the top left border even though I have the iframe 'display' property set to 'table-cell' & 'vertical-align' to 'middle'.
The HTML code:
<!-- the container div -->
<div id="iframe_r_container">
<!-- iframe -->
<iframe id="iframing" src="mannequin.html" frameborder="0" ></iframe>
<!--div--> <div id="right_container">
<div id="user_credit">
<h1>Username</h1><br />
has <span id="credits">20,000</span> credits.
</div>
<div> <button id="template_button"><img src="images/Coutallure-WebApp/template_button.png" /><span>Templates</span></button> </div>
</div>
And here is the CSS:
/* START OF IFRAME_R_CONTAINER */
#iframe_r_container {
position: absolute;
display: table;
top: 48px;
bottom: 38px;
width: 960px;
}
/* START OF IFRAME */
#iframing {
display: table-cell;
width: 640px;
height: 480px;
vertical-align: middle;
}
/* END OF IFRAME */
/* START OF RIGHT CONTAINER */
#right_container {
display: table-cell;
vertical-align: middle;
width: 113px;
margin: 20px;
}
I have been stuck at this for half a day today so any help would be immensely appreciated.
If you don't mind using another technique than table-cell centering, you can try something like this :
#iframe_r_container {
position: absolute;
top: 48px;
bottom: 38px;
width: 960px;
}
/* START OF IFRAME */
#iframing {
position: relative;
top: 50%;
margin-top: -240px;
width: 640px;
height: 480px;
float: left;
}
/* END OF IFRAME */
/* START OF RIGHT CONTAINER */
#right_container {
position: relative;
top: 50%;
height: 113px;
margin-top: -57px;
margin-left: 670px;
width: 113px;
}
It works here on my FF/mac but you'd have to test it on other browser.
To center #right_container, you'd have to give it a heigh (here 113px) and set the negative margin-top accordingly.
Also, you may want to give a min-height: 640px to #iframe_r_container to avoid the iframe overflowing outside of its container.
I am not sure what are you trying to achieve, but just from reading your post - you cannot try centering element itself with some align property, this must be property of its parent element. You should try that margin, i think this is the right property to work with.
Adding "height" to your containers should do it. Just adding it to your iframe container worked for me in FF on my Mac.
#iframe_r_container {
position: absolute;
top: 48px;
bottom: 38px;
width: 960px;
height:480px;
}
(Note: Internet Explorer 8 (and higher) supports the property values "inline-table", "run-in", "table", "table-caption", "table-cell", "table-column", "table-column-group", "table-row", "table-row-group", and "inherit" only if a !DOCTYPE is specified.)
try these settings:
/* START OF IFRAME_R_CONTAINER */
#iframe_r_container {
position: absolute;
top: 48px;
bottom: 38px;
width: 960px;
}
/* START OF IFRAME */
#iframing {
width: 640px;
height: 480px;
margin: 0 auto;
}
/* END OF IFRAME */
/* START OF RIGHT CONTAINER */
#right_container {
vertical-align: middle;
width: 113px;
margin: 0 auto;
}
The attribute margin: 0 auto; will (hopefully) center your iframe and other div inside the container. Not tested but give it a try.
