I have a div I would like which I have placed at 25% from the top. However, the 25% are computed with respect to the size of the background image and not with respect to the size of the visible screen. How can this be fixed?
Update: now the top margin works, but not the left one :(
Any clue?
body {
background: #eeeeee url('pix/bg-noether-2.jpg') no-repeat center top;
background-size: auto 100%;
background-attachment: fixed;
overflow: hidden;
align: center;
}
#container {
background-color: #ffffe4;
position: absolute;
width: 776px;
height: 400px;
top: 25%;
margin-left: auto;
text-align: center;
overflow: auto;
}
1) use absolute positioning:
#myDiv { position: absolute; top: 25%; }
2) make sure your div is not within another positioned element (if you're not sure of this, just put it just inside the <body> tag, nothing else)
use css property:
div#myDiv {
position:absolute;
top: 25%;
}
on the dive that you want placed 25% from top of visible screen.
if you use relative position then the percentage will be calculated from the parent element.
if you use absolute position the percentage will be calculated from the size of the screen.
So try to using position absolute instead of relative.
edited answer for comment, just add extra div with id wrapper and change postitions, see example below:
<html>
<head>
<style type="text/css">
body {
background: #eeeeee url('pix/bg-noether-2.jpg') no-repeat center top;
background-attachment: fixed;
overflow: hidden;
text-align: center;
}
#wrapper {
position:absolute;
width:100%;
height:100%;
}
#container {
background-color: #ffffe4;
position: relative;
margin:0 auto;
width: 776px;
height: 400px;
top: 25%;
text-align: center;
overflow: auto;
}
</style>
</head>
<body>
<div id="wrapper">
<div id="container">
bla bla bla
</div>
</div>
</body>
</html>

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;
}

I have my "header_main" positioned absolute with a height of 100% to basically cover the entire screen. Inside the header_main div n have another div positioned absolute as well. I have set the "icon-wrapper" div to bottom:0; but it does not want to position absolute bottom.
<body id="top" class="no-js">
<header id="header_main">
<div class="icon-wrapper"></div>
</header>
</body>
My CSS:
html, body {
height: 100%;
}
body{
font: 18px/27px $font-stack;
color: $text-color;
-webkit-font-smoothing: antialiased;
font-weight: 300;
}
#header_main{
height:100%;
width:100%;
position: absolute;
background: url('../images/ac-placeholder-img.jpg') no-repeat center center;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}
.icon-wrapper {
position:absolute;
height: 254px;
bottom: 0;
vertical-align:bottom;
}
It can be done by giving top:100%; to the icon wrapper it will be always to the bottom of the header_main check out the working demo below;
#header_ main{
height:100%;
width:100%;
position: absolute;
background:#ddd;
}
.icon-wrapper {
position:absolute;
height: 254px;
bottom: 0;
background:red;
top:100%;
vertical-align:bottom;
}
<body id="top" class="no-js"> <header id="header_main"> Scroll Down<div class="icon-wrapper">ww</div> </header> </body>
.icon-wrapper is being aligned to the bottom, but its content is not, because the display value of absolute-positioned elements is always table or block, and vertical-align applies to inline or table-cell elements only.
Use the wrapper for the absolute positioning only, and add another element to handle the vertical align:
CSS
.icon-wrapper {
position: absolute;
bottom: 0;
}
.icon {
display: table-cell;
vertical-align: bottom;
height: 254px;
}
HTML
<div class="icon-wrapper">
<div class="icon">
</div>
</div>
Fiddle
You need to set the width for the absolute positioned div.
.icon-wrapper {
position:absolute;
height: 254px;
bottom: 0;
vertical-align:bottom;
width: 100%;
}
I have this simple HTML code, but make me frustrated because it can't center vertically :
<div class="outer">
<div class="inner">
Hello World
</div>
</div>
and here's my CSS :
.outer {
position: relative;
height: 350px;
}
.inner {
position: absolute;
height: 100px;
top: 50%
}
the .inner div is really center vertically, but based on top side of it. because of top: 50%, what I want is this .inner div really centered vertically on top of .outer. how to do that?
You can center your element using css3 even if you don't know the dimensions.
.inner {
position: absolute;
height: 100px;
top: 50%;
transform: translateY(-50%);
-webkit-transform: translateY(-50%);
}
Since you know the height of both elements you can set your top to top: 125px;
(350 - 100) / 2.

Actually an easy way to center a absolute div is to use margin: auto;
section {
width: 100%;
height: 800px;
position: relative;
background: #eee;
}
div {
width: 500px;
height: 300px;
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
margin: auto;
background: orange;
}
<section>
<div></div>
</section>
I added borders to differentiate clearly
Is this you want?
http://plnkr.co/edit/JRct1x95gnIUl8jITzG0?p=preview
.outer {
position: relative;
height: 150px;
border : 1px solid #f00;
}
.inner {
position: absolute;
height: 80px;
top:0;
bottom:0;
margin:auto;
border : 1px solid #0f0;
}
You could use this CSS trick to make the div vertically centered (and optionally horizontally as well). This works for a parent div of any height and width, as long as they are specified.
.inner {
position:absolute;
// The height and width of the element have to be set for this to work
height:100px;
width:100px;
// Setting the top and bottom to 0px as well as the margins to auto
// causes the div to be centered vertically.
top: 0px;
bottom: 0px;
margin-top: auto;
margin-bottom: auto;
// To also center the div horizontally, do the same for
// left, right and the margins.
left: 0px;
right: 0px;
margin-left:auto;
margin-right:auto;
}
Note that this solution only works when the height of the parent div is known beforehand and is specified. So the parent element needs to have height:100px or whatever amount of pixels you need it to be. Also the height can't be percentual, meaning that if the height of the parent div is declared as height:50%, this will NOT work.
The inner div can actually have a
You can set it by line-height property set it to the height of the div as in your code it should be line-height: 100px;
.outer {
position: relative;
height: 350px;
background: gray;
}
.inner {
position: absolute;
height: 100px;
line-height: 100px;
background: blue;
}
<div class="outer">
<div class="inner">

I have a fixed header that i want to keep behind the container div as I scroll down the page. as seen on http://www.madebydaryl.co.uk/. It's sorta working except the background of the content div seems to be hidden behind the background of the header. Not sure how to solve this..
My css:
header{
position: fixed;
background: url(images/mainbg_blur.png) no-repeat center;
background-size: cover;
height: 100vh;
display: table;
width: 100%;
z-index: 1;
top:0;
left:0;
}
.container {
position: relative;
margin-top:100vh;
background: #fff;
z-index: 2;
}
EDIT:
This kinda worked:
header{
position: fixed;
background: url(images/mainbg_blur.png) no-repeat center;
background-size: cover;
height: 100vh;
min-height: 100%;
width: 100%;
display: table;
top:0;
left:0;
}
.container {
position: relative;
width: 100%;
height: 100%;
min-height: 100%;
margin-top:100vh;
background: #fff;
}
Except the background of the container div doesnt stretch to cover all of the content, just the height of the viewport. Any ideas?
The effect that you are talking about is known as Parallax Sliding effect,

Alas, such a simple solution.
Just put another div inside the container div, and give it the background color.
so:
<header>content</header>
<div class="container>
<div class="bg">
Main content
</div>
</div>
and the same css except move the background to the .bg.
I have what is a fairly common page layout where the content div is centralised on the page using margin:auto 0. The width of the div itself varies depending on available page width.
I want another div featuring a logo to 'stick' to the outside left hand side of this div (ie no gap or overlap between the two) at a fixed height. What CSS should I use for this?
something like
html:
<html>
<div id='content'>
<div id='stickything'>a</div>
</div>
</html>
css:
html {
width: 100%;
}
#content {
position: relative;
width: 100px;
height: 600px;
margin: auto;
background-color: green;
}
#stickything {
position: fixed;
width: 25px;
height: 30px;
top: 0px;
margin-left: -25px;
background-color: red;
}

Use position:absolute. It must help:
.container-div{
position: relative
}
.outer-div{
position:absolute;
top: 0 (your choice)
left: -/outer div's width/
}
