I would like to center some div which has background image. There is problem with response of this div, because if I set width on 80% and height on 80% the bg-image is not on center. I tried everything, but the picture can't just stand on center and if the browser is smaller or bigger this is very big problem.
So if you look at the picture
I want to make this white block responsive.
There is a little of css which I've already written, but for now is non-responsive:
top: 20%;
left: 30%;
display: block;
position: absolute;
background: url(images/background.png) no-repeat;
background-size: 750px 417px;
width: 750px;
height: 417px;
You could use CSS transform:
position: fixed;
left: 50%;
top: 50%;
transform: translate(-50%, -50%);
I wanted to do the same thing 2 years ago, there's the solution:
Because you want it responsive, you may use the #media function in CSS3. Like this:
#media (max-width: 480px) {
#div {
top: 50%; /* IMPORTANT */
left: 50%; /* IMPORTANT */
display: block;
position: absolute;
background: url(images/background.png) no-repeat center center;
width: 750px;
height: 417px;
margin-top: -208.5px; /* HALF OF THE HEIGHT */
margin-left: -375px; /* HALF OF THE WIDTH */
}
}
The max-width you use is the maximum width of the device screen. You just copy it and change the width, height, margin-left and margin-top for the image. Also, you should change the background tag!
It will center the image on the page.
You can see an exemple at: Créations MicroWeb - Carrières. The image is totally centered even if you change the window side.
You can add overflow: hidden; on the body to make the page unscrollable when the resolution is too low. Like I did.
EDIT: JSFiddle
Try with auto margins and display as table:
.your-class {
margin-left: auto;
margin-right: auto;
display: table;
}
You can use margin:0 auto; to center a div horizontally as long as its width is less than that of the container div.
Please try this:
img { max-width:100%; max-height:100%; margin:auto; }
.container{display: flex; justify-content: center; align-items: center}
I have used display: inline-block; on element to center and text-align: center; on parent div.

I have been researching this issue for the last few days, and while have found several solutions that work well in static layouts, I am having a problem resolving in responsive design.
We have a series of banner images that we use on our home page, and are trying to get them to appear centered on the image behind text on smaller mobile screens. I can solve this for fixed widths, but we need to make this responsive.
Here is what the current rendition of my CSS code looks like:
#mainSlideshow .item img {
display: block;
width: auto !important;
max-width: none !important;
height: 350px !important;
overflow: hidden;
left: 50%;
-webkit-transform: translateX(-50%);
-moz-transform: translateX(-50%);
-ms-transform: translateX(-50%);
-o-transform: translateX(-50%);
transform: translateX(-50%);
}
#mainSlideshow .item .carouselImgHold {position: relative; }
The challenge appears to be the movement left - right now, the image just shifts to the left 50% of the img width (no surprise). How do I program the CSS to drift the image only the amount necessary to center the image in the nested div tag?
Many thanks in advance.
It would be nice if you could give us an example but lets try. :)
My suggestion is to set image as background-image instead of linking it. So that would look like:
#mainSlideshow .item{
background-image:url("path-to-image/image.jpg");
background-size:cover;
background-position:center center;
background-repeat:no-repeat;
}
That way you will have not stretched image covering the #mainSlideshow .item .Read more about that here
You may use text-align and negative margins if IMG stands alone on its line.

.oversizedImage {
text-align: center;
}
.oversizedImage img {
margin: 0 -100%;
}
/* demo purpose */
.oversizedImage {
width: 50%;
margin: auto;
border: solid;
box-shadow: 0 0 150px 100px white;/* you should use overflow:hidden; here it only shows how much is outside :) */
}
.oversizedImage img {
vertical-align: top;
/* instead default baseline to avoid gap under */
position: relative;
z-index: -1;
}
<div class="oversizedImage">
<img src="http://lorempixel.com/1200/200"/>
</div>
It is only a guess since we miss your HTML
I think you can achieve this to ways.
img {
display: block;
margin-left: auto;
margin-right: auto
}
Or
img {
width: 50%
left: 50%
}
I have a square image that I want to have centered on the screen. Problem is that I want the image to stay a square, while being not more than 80% of both the width and the height. I have used the following code, which makes my image 80% of the height (when height < width), and centers the image vertically, but not horizontally of course. When using a fixed width, I could have used margin-left: 50%; margin-right: 50%, but with relative size, this would set the left side of the image at 50%. Any ideas?
.my_img{
max-width: 80%;
max-height: 80%;
margin-left: 10%;
margin-top: 10%;
}
Try this:
.my_img_container {
position: relative;
}
.my_img {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%,-50%)
}
Here is a fiddle:
http://jsfiddle.net/l0wskilled/voubtxrt/
if your image has display: block then you can probably use margin: auto auto and remove the % margins. If its display is inline or inline-block, you can use text-align: center on the parent element of the image to make it horizontally centered. I have not tested this code. If this doesn't work, and you have no problem with jQuery, this can be done with few lines of jQuery.
You could also try:
<div class="container">
<img src="https://www.webkit.org/blog-files/acid3-100.png" class="my_img" />
</div>
With the style:
.my_img {
max-width: 80%;
max-height: 80%;
margin-left: auto;
margin-right: auto;
display: block;
}
I think this is what you are wanting anyway, maybe i'm wrong!

Ok...here is my problem:
I have a webpage with html & body set from css to:
body,html{
position: fixed;
width: 100%;
height: 100%;
overflow:hidden;
}
and also a webkit tag to disable the scrollbar:
/*Disable scrolling*/
::-webkit-scrollbar {
display: none;
}
inside of the body i use 3 divs to cover the entire available space in the page:
(i will not use the actual css code for the divs because it's unimportant for this matter and i will write only a basic code to get the ideea)
As i said, three relative divs to cover the available 100% height and width:
.div1{
position: relative;
width: 100%;
height: 10%;
}
.div2{
position: relative;
width: 100%;
height: 80%;
}
.div3{
position: relative;
width: 100%;
height: 10%;
}
Now here is my problem:
* inside the middle div (div2) i have 4 concentric circles all of which are absolute divs wrote in css3. It is really important that these divs remain "absolute".
here is the css for them:
.size-large,
.size-normal,
.size-small,
.main-frame{
position:absolute;
left:0;
right:0;
margin:0 auto;
background: transparent;
border: 3px dotted #999;
-moz-border-radius: 50%;
-webkit-border-radius: 50%;
border-radius: 50%;
top: 50%;
}
.main-frame{
width: 50%;
padding-bottom: 50%;
margin-top:-25%; /* push back half */
}
.size-large{
width: 30%;
padding-bottom: 30%;
margin-top:-15%; /* push back half */
}
.size-normal {
width: 20%;
padding-bottom: 20%;
margin-top:-10%; /* push back half */
}
.size-small {
width: 10%;
padding-bottom: 10%;
margin-top:-5%; /* push back half */
}
Problem is that those circles does not resize acording to the relative div of which they belong.
Their width/height given in percentages, is set acording to the body element.
I want my design to be liquid and to use only the available webpage without scrolling but also to resize all it's elements on any display.

CODE VIEW: http://jsfiddle.net/Nn7mU/1/
From my understanding, you want to ensure your concentric circles to stay within the blue div whilst maintaining a perfect round circle according to the percentage width you have set (i.e. .main-frame {width: 50%}, .size-large {width: 30%), .size-normal {width: 20%}, .size-small {width: 10%})
Your circles are indeed adjusting according to your blue div (based on width % not height %). So since your blue div has width=100%, the circles will adjust according to that only.
You will need to find a way of using BOTH height and width % so it maintains aspect ratio and central positioning.
I would recommend reading on this thread which provides possible solutions:
HTML and CSS Fluid Circle
Height was not respected on this fiddle
I want the image to have a height and width of 80% relative to its parent, vertically and horizontally aligned. For some reason, it does not work.
HTML:
<div id="menu_header_new_orig">
<img id="menu_logo_orig" src="https://imagizer.imageshack.us/v2/849x565q90/833/uua2.jpg" />
</div>
CSS:
#menu_header_new_orig {
margin-top: 2.5%;
height:40%;
width:100%;
overflow: hidden;
position: relative;
border: 1px solid green;
text-align: center;
}
#menu_logo_orig {
width: 80%;
height: 80%;
position: relative;
}
I have figured it out here, but just in case somebody have better solution.
If I understand you correct :
The parent #menu_header_new_orig own parent must also have a height (obviously 100%)
html, body {
height: 100%;
}
set display to inline, 10% top to get vertical alignment
#menu_logo_orig {
top: 10%;
display: inline;
position: relative;
width: 80%;
height: 80%;
}
Is that what you were heading for? [not really sure] - try to set #menu_header_new_orig height to other things than 40% to get it in another perspective.

I've got this logo I'm trying to use on a responsive site, but I can't figure out how to have it so it fills the full width of its parent element while maintaining its ratio in height.
When you start resizing the browser window, the logo gets smaller in width but its height doesn't scale properly. Is there a way to maintain this.
Here's my CSS for the logo element:
h1 {
width: 100%;
height: auto;
background: url(http://images.uncyclomedia.co/uncyclopedia/en/thumb/c/ce/Coca-Cola_logo.svg/800px-Coca-Cola_logo.svg.png) no-repeat top left orange;
background-size: contain;
text-indent: -999999px;
text-align: center;
margin-top: 270px;
}
This is the problem I'm having. Look at all that extra space below the
logo.
And here's a CodePen with an example of my issue:
http://codepen.io/realph/pen/LAFsi
Any help with this is appreciated. Thanks in advance!
You could use a padding trick (see CSS-square container) to do what you want with one image
h1 {
background: url(http://images.uncyclomedia.co/uncyclopedia/en/thumb/c/ce/Coca-Cola_logo.svg/800px-Coca-Cola_logo.svg.png) no-repeat top left orange;
background-size: contain;
text-indent: -999999px;
text-align: center;
position:relative;
width:100%;
height: 0;
padding-bottom: 30%;
display:block;
}
