I have a sprite image being used as a background:
#block {
width: 143px;
height: 144px;
background: #0f0 url(http://www.w3schools.com/css/img_navsprites.gif) no-repeat -91px 0;
}
<div id="block"></div>
I want to position the background image at a specific top/left offset (for example 10px from the top and left of the container element). How can I do this?
Because you use CSS sprite you can't position it the way you want. but this solution might help. Using margin on an additional element having the background image in order to position it:
.BlockBox {
display: inline-block;
background-color: #0f0;
width: 200px;
height: 200px;
}
#block {
margin: 100px 0 0 10px;
width: 44px;
height: 44px;
background: url(http://www.w3schools.com/css/img_navsprites.gif) no-repeat -91px 0;
}
<div class="BlockBox">
<div id="block"></div>
</div>

Recently I have come across a problem for which I am not finding any appropriate solution.
Below is the image which gives an idea of what i am trying to achieve:
The div shown by the arrow is the mark of the problem which i am finding a solution for.
The problem is I want the div to be extended to full screen.
This div is inside a parent div who has a fixed width due to which i am not able to extend my image to full screen.
Have tried giving overflow to parent but isn't working.
I have tried below solution which is working to a certain extent but need a reliable solution.
width: 100%;
left: 0;
position: absolute;
margin-left: calc(-31.5vw);
align-content: center;
Could someone please provide some solution to this?
html, body
{width: 100%; height: 100%; overflow: hidden;}
#parent{
display: block;
background-color: yellow;
border: 1px solid red;
position: fixed;
width: 200px;
height:100%;
}
#child1{
background-color: red;
display: block;
border: 1px solid yellow;
position: absolute;
width: 100vw;
margin-left: calc(200px - 100%);
//top:0px
}
<div id="parent">parent with position: fixed
<div id="child1">child wrapper (uncomment top to fit the parent wrapper)</div>
</div>
use Viewport Sizes so it will cover the whole page (vw and vh)
#first {
width: 100px;
height: 100px;
background:gray;
position: fixed;
top: 0;
left: 0;
}
#second{
width: 100vw;
height: 100vh;
background:blue;
position:absolute;
}
<div id="first">
<div id="second">
something
</div>
</div>
The below code snippet should work, if I understand your question correctly. Setting the width of the child div to 100vw makes the div 100% of the width of the viewport (window).
Also note that in order to get the child to start at the left of the viewport and not the left of the parent, I gave the child a position of absolute and a left of 0. Because the parent is not positioned, it starts the left of the child at the left of the viewport (the closest positioned ancestor).
#parentDiv {
width: 250px;
height: 250px;
margin: 0 auto;
background-color: orange;
border: 2px solid red;
}
#childDiv {
/* 100vw is 100% of the viewport width. */
width: 100vw;
height: 50px;
background-color: lightblue;
box-sizing: border-box;
border: 2px solid green;
position: absolute;
left: 0;
}
p {
text-align: center;
}
<html>
<body>
<div id="parentDiv">
<p>Parent</p>
<div id="childDiv"><p>Child</p></div>
</div>

Received a two column layout design for a website. Each column has a transparent background that, combined, forms a curved cut-out at the top.
I need the columns to grow with content, however this distorts the background image when set on background-size: cover (Matching things up in order to use repeat-y won't work either). Is there a good way to accomplish this, or a way to tell him absolutely not?
.middle-left-container {
float: left;
min-height: 500px;
position: relative;
left: 0;
bottom: 0;
background-image: url('/tlm-wp/wp-content/uploads/2016/11/left-menu-background-sliced.png');
background-repeat: no-repeat;
background-size: cover;
width: 20%;
}
body:not(.home) .middle-left-container {
top: 0;
background-image: url('/tlm-wp/wp-content/uploads/2016/11/left- menu-main.png');
}
.middle-right-container {
float: left;
min-height: 500px;
position: relative;
top: 0;
right: 0;
bottom: 0;
background-image: url('/tlm-wp/wp-content/uploads/2016/11/banner-bg.png');
background-repeat: no-repeat;
background-size: 100% 100%;
height: 100%;
width: 80%;
}
body:not(.home) .middle-right-container {
background-image: none;
background-color: #fff;
}
Thanks,
Matt
Don't put the curved bg image on the <body>, put it on a fixed-width container, then anchor the bg-image position.
.container {
width:900px;
margin:0 auto;
background-position: top center;
...
}
Then inside that container, put each of your column containers. Something like:
<div class="container">
<div class="sidebar-nav"> ... </div>
<div class="middle-left-container"> ... </div>
<div class="middle-right-container"> ... </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;
}

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.
UPDATED WITH JQUERY

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">
Hello World
</div>
</div>
I wish to center my font icon at the bottom of the div. I know that I could have it positioned absolute to the background and use bottom:0 but I can't get margin:auto to center it either side.
Here is my code:
<section>
<p><i class="fa fa fa-arrow-circle-o-down"></i></p>
</section>
section {
background: url("../img/background.jpg") no-repeat center center fixed;
background-size: 100%;
background-color: black;
height: 100%;
position: relative;
}
section p i {
position: absolute;
color: white;
font-size: 15em;
bottom:0
}
Your icon is a text, so you can use the property text-align: center;.
A jsfiddle sample. I made some modifications in the code.
html
<section>
<p><i>☺</i></p>
</section>
css
section {
background: black url("http://placehold.it/420x150") no-repeat center center; // you can put the background-color here by the way
background-size: 100%;
height: 150px;
width: 100%;
position: relative;
text-align: center; // magic stuff here !
}
section p i {
position: absolute;
color: red;
font-size: 2em;
bottom: 0; // you forget a ';' here
}
Is this what you are looking for ?
