i need your help! My client wants a wordpress page with full screen backgrounds.
On one of the pages, i need to place 3 images on the fullscreen background image that stay in the exact position and are fluid themselves.
3 persons on the image should be selectable and there will be a lightbox with information about them.
this is how it should look:
this is how the background is positioned:
.bg{
background: url(images/gang.jpg);
background-repeat:no-repeat;
background-position: center center;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
width:100%;
height:100%;
position:fixed;
left:0;
top:0;
z-index:-700;
}
so i need three more pngs as hover images, that stay on the three persons.
there would be no problem if it shouldnt be fluid.
is there a way to do it with css? i'm a bit of a javascript noob, but if there would be a way, please let me know.
i thought 3 pngs in the exact same size as the background and with CSS-Mask would be a solution, but even FF doesnt support that so thats no option.
Any ideas?
thanks guys and excuse my english!
Rather than using using background-size:cover or background-size:contain with a full-width bg image:
Split the content area up into 3 columns (1 for each person).
Use a responsive design or fluid layout for the width of each column (or if necessary, use JS or jQuery to detect the width and height of the browser and calculate the width needed for each column).
Add a hyperlink in each column with display:block; width:100%;.
Add a pair of img tags to the hyperlink with width:100%; height:auto; (default image and hover image).
Add mouseover/mouseout event handlers to each hyperlink (using JS or jQuery) that toggle which img tag is hidden.
The advantage of using columns is that the hyperlink hotspots will always match the size and location of each image (which otherwise might be difficult to do for all screen sizes and orientations).

I have the following HTML code:
<header id="header">
<h1><span id="titlu-pagina">Watercolors</span></h1>
<ul>
<li>About Me</li>
<li>Where To Find Me</li>
<li>The Blog</li>
</ul>
</header>
and the respective CSS one:
#header {
height: 800px;
text-align: center;
border-bottom: 1px solid black;
background-color: #734C8F;
background-image: url('10.jpg');
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover !important;
}
I am trying to set up an image as a background for the header but for some reason the image is not displayed in its full size. I've tried low res images and still, some parts are cut from it. If I resize the browser the image scales and in the end it gets to its full size.
If I change the code to
background-image: url('10.jpg') no-repeat center center fixed;
the image doesn't display at all. What am I doing wrong? I've tried the code in all browser but the result is the same.
Looks like this is/was simply a misunderstanding on your end, of what background-size: cover actually does.
https://developer.mozilla.org/en-US/docs/Web/CSS/background-size:
[cover] scales the image as large as possible and maintains image aspect ratio (image doesn't get squished). The image "covers" the entire width or height of the container. When the image and container have different dimensions, the image is clipped either left/right or top/bottom.
(“When the image and container have different dimensions” should rather be “have different aspect ratios” – because if they had not different dimensions, but width and height of image and element would be exactly the same, then we would not need to apply background-size in the first place.)
If you want the image to get “squished” instead of clipped – then use background-size: 100% 100%.
Can I ask you when is generally recommended to use the 100% 100% background-size and when it would be better to use :cover? It's not very clear to me how are they doing two different things in terms of covering the container.
background-size: 100% 100% means, stretch the image in both dimensions to 100% of the respective container dimension. If the aspect ratio of the image and the element don’t match, the image will be distorted/squished.
cover however is intended to scale the image to be as large as possible, while keeping it’s aspect ratio.
Think of it like watching a movie on your TV screen. Cinema aspect ratio and TV aspect ratio usually differ (or at least used to, with older TVs.) Now usually you’d want to see all of what is going on in the picture, and not miss anything that happens “on the sides” of the it. Therefor the movie is scaled in a way that it covers the whole width (or height) of the screen, and you get black bars on the top and the bottom (or left/right) – thereby the aspect ratio of the movie is kept – because you would not want to watch a movie distorted, that just looks weird when car tires are ovals and the people have unnaturally wide or long faces.
That analogy make things clearer …?
To make your background-image resize without cropping it must be proportionate to the parent, or header. If your header has a 16:9 ratio then so must your image. They need to resize together. But this seems more tricky than it needs to be.
The alternative would be to use the following structure;
<header>
<img />
<nav></nav>
</header>
The image sits inside the header. The nav (which sits on top of the image) is absolutely positioned relative to the header.
This may need some further media-queries to manage font-sizes and nav list items for smaller screens.
JS Fiddle
#header {
text-align: center;
border-bottom: 1px solid black;
background-color: #734C8F;
background-image: url('10.jpg');
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover !important;
width:100%
min-height: 100vh;
}
I have add 2 lines of code to your header section by this you can able to solve your problem
Bro instead of using background-image: url ('x') no-repeat center center fixed; in you above alternate i suggest you this is the format.. background:url ('x') no-repeat center center fixed; because the background short hand property in css is what i suggest in my message.. thk you bye frnds

Width of image boxes is responsive
How to set the height to be responsive too? Like 50% of the screen?
If I do this change:
.pattern{
background-size: contain;
margin-bottom:25px;
width:100%;
height:50%;
}
it's not working
Thank you very much!
background-size: needs to come AFTER background: I don't know if this is true of all browsers, but it's certainly a feature of Chrome that can drive you crazy.
This might be a bit late but in some cases it's necessary to add background-attachment: fixed; to get background-size: cover; working.
You need to use background-image property to define background image.
So this won't work
<img class="image" style="background: url(image.jpg);" />
.image { background-size: cover; }
because background is the shorthand code and takes default values for all omitted parameters.
But if you do this
<img class="image" style="background-image: url(image.jpg);" />
.image { background-size: cover; }
This wil solve the problem.
The height of the div can be set using css height property, or (by default) by the height of it's children elements. As the images are being set as background images the div is unable to determine the height it should be from that, and there is no pure css method of adjusting the height of a div to fit the dimensions of a background image. What you can do, is set the background images to be positioned in the centre of the div and have the background size as cover:
.pattern-container .pattern {
background-size: cover;
background-position: 50% 50%;
<!-- other rules here -->
}
Positioning the background images as 50% 50% vertically and horizontally centres it in the containing div regardless of the dimensions of the div. That said, the image itself may crop at the edges if the aspect ratio of the div is less than the aspect ratio of the image (e.g. if the div is 30px wide and 10px high, and the image is 40px wide and 10px high, then the image is going to lose 5px from both sides).
You can use ;
background: url('/path');
background-size: cover;
//in the style sheets
In some cases, there may be empty space in the edges of your image itself (e.g., an icon that is surrounded by 16px of blank white space on each side) making it seem like background-size: cover; is not working when it actually is.
Just a reminder to double-check your source image :)
The image boxes are responsive, but this does not mean that the corresponding images are. For a more fluid and dynamic structure, I recommend using a framework that does the work for you, like Bootstrap.
In the latest version of Bootstrap you could use the following code to make a responsive image (both in width and height):
<img src="images/my_img" class="img-responsive" />
In order for this to work, you will need to download the latest version of Bootstrap from their website (http://getbootstrap.com/) and reference in your code.
I have a template for a website, it's an image which i have set as a background image. Now what i need to do is place html over it. For example there an part of the whole template where some images are but eventually when they are clicked they need to do something. So i need to place some divs over the whole template containing the different parts.
I don't know what the right approach for this is. What i've done right now is set the background image like this:
#body{
width:1280px;
height:8000px;
background: url(something.jpg);
background-repeat: no-repeat;
background-position:center;
}
So it always centers the image if you were to resize the window it would stay centered. This works fine.
Now i need to add another div in the body (of course) which needs to stay on top of the image.
I've tried and searched on the internet alot but the div seems to have a position that can't move. so how i resize the window it keeps in the same place.
I hope it's a little clear what i'm trying to do, and keep in mind this is my first time doing something like this so any help is greatly appreciated.
Thanks in advance!
PS: i'm not trying to cover the whole page in the background, just the original size which is 1280 all the time, and if the window gets resized bigger than 1280 in width it needs to center the image.
(if you're trying to set an image as the body's background to cover the whole screen)
Instead of settings width's and height's on your body, you should just set the size of the background to cover
css-tricks.com/perfect-full-page-background-image
body {
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}
You can do this so the image is always centered
.main{
width:600px;
margin:50px auto;
}
<div class="main">
<img src="path to img"/>
</div>
I've searched for hours upon hours and now I figure it's time for me to ask the question. I can't get my background image that is placed in my header to fit to screen. It works for every kind of computer resolution fine, but where I run into trouble is when I am viewing on a phone, it doesn't want to shrink. I've done min-height, max-height, I've tried everything, the problem partly I think is that the header div itself is smaller than this image, but I also don't really know and need some guidance, i'm relatively new to the CSS scene.
Here is what I have:
#header {
background-image: url('http://hamsoc.polymath.io/wp-content/uploads/2013/05/hamsocheader.png');
background-repeat: no-repeat;
background-position: center center;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
height: 209px;
}
Website url is http://hamsoc.polymath.io
Thank you for your help in advance!
Duncan Beattie gave me the answer and it worked like a charm. Here is what he said:
"You have background-size: cover which is fitting the height of the
background image to the fixed height of your div, 209px. remove the
fixed height and replace with padding-bottom:15% this will kep the
aspect ratio of the div the same and scale the image as viewport gets
smaller."
You have background-size: cover which is fitting the height of the background image to the fixed height of your div, 209px.
remove the fixed height and replace with padding-bottom:15% this will kep the aspect ratio of the div the same and scale the image as viewport gets smaller.
I would suggest having the header image in your HTML rather than a background image and then setting a max-width like so:
#header img{
max-width: 100%;
height: auto;
}
This will also allow you to make the image "clickable" which is generally wanted in a header logo.
DEMO FIDDLE
FULLSCREEN
Have you used the a precentage to set the height of the image in the div?
So set the image height to be say 100% of the div?
If not then maybe you could use some javascript code to detect whether they are on a mobile device, and set the height of it accordingly?
The hard coded height value is messing you up. Try playing with the height: 290px value and watch the header fit properly on smaller screens.
Instead of a background image, you can try putting the image in the html and using a CSS property to help the content scale down on smaller screens.
img {
max-width: 100%;
}
I was wondering how i can make an image across the browser such that even though, my website is viewed in a larger monitor, the image will still span out and extend without showing a white space at the end.
You basically have two choices:
Use a repeating pattern that fills the entire width: you can do this using
width: 100%; background: url(your-image-file) repeat-x
Use a fixed main image and a background filler image that fills the remaining area: the background would use the same code as above and the main image could be an img within the background container.
Well, to start, lets clear your margins with this code.
* {
margin: 0;
padding: 0;
}
By using this in your style sheet or section, it will allow for those images to stretch all the way with no white space.
Next, you'll want to create an image that doesn't look skewed. To do this you will need to create it in a fairly wide format to begin with. If you are looking to fill the entire background, I would suggest 1028X768 px as a good size.
Finally, it's time to place the last bit of code and get it all working.
html {
background: url(images/bg.jpg) no-repeat center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}
This will work with dang near all current browsers (except IE8 and below).
In order to place an odd size image that you want to span but not entirely cover, I would suggest using a <div> to create a place for the image and add a style to the <div> that says width: 100%;.
This can be done with height as well.
Hope this helps.
