I was wondering if someone could point me in the right direction. I have a div with a large background image. The BG image is set to contain so it will expand and contract with browser size. The issue I'm having is if you shrink the browser, the div still shows the height to 1000px. So while the image expands properly to fit, if you begin to scroll down you see the large gap that now occupies the 1000px height under the picture where the body bg color comes through (since the picture has shrunk via the contain). How can I make it so the div moves up and the gap disappears? I have seen this done on several sites.
CSS Code:
.contain { background-size: contain; }
.mainsplashtop {
width:100%;
height:1000px;
background-image:url(../images/main_splash.jpg);
background-repeat:no-repeat;
margin-top:0;
}
HTML
<div data-stellar-background-ratio="0.5" class="mainsplashtop contain"><a class="scroll" href="#destination1"></a></div>
You can see what I mean on the site (please disregard the disaray as its still in early development)

Here are examples of what im trying to achieve.

Thanks in advance.
I want to make a panel with background image, which can be resized vertically. So the simple idea is to split actual image in three parts: header, body-repeat-part, footer. It looks something like this
<tr><td><div class='header'></div></td></tr>
<tr><td><div class='body'>whatever goes here</div></td></tr>
<tr><td><div class='footer'></div></td></tr>
.header {background:url(header.png); width:110px; height:20px;}
.footer {background:url(footer.png); width:110px; height:40px;}
.body {background:url(body-repeat.png); repeat-y; width:110px;}
So I slice my image which is 100x100 into three parts - header.png - 100x20, footer.png - 100x40, and body-repeat.png - 100x1
Everything works fine in Ie9 and firefox. And even chrome works fine with 100% zoom. However when I change zoom in Chrome the picture becomes jagged i.e. you could see it's "glued" from 3 parts. Apparently chrome scales differently these images.
So my question is - could this be fixed somehow? Or is there any way to make resizable panel with background image?
Many thanks for the replies.
You can try to force no paddings, borders and margins on that tables and divs, and then try to add the CSS3 background size property!
.header {
background-image:url(header.png);
background-size:110px 20px;
}
More about CSS Background size properties: http://www.w3schools.com/cssref/css3_pr_background-size.asp
It is better too try to avoid tables when making a layout structure :)
EDIT:
You can try too to add the
background-size: cover;
property on the full page background so the background image will fit 100% of the width and height of the given area.
A great and very complete tutorial about background-size: http://www.css3.info/preview/background-size/
Here is an example of how I am currently implementing this functionality:
EXAMPLE
The content div can change in height dynamically when items are added or removed so I need the gradient to move with it. This works great in desktop browsers... However when you view it on an iPad and scroll down (moving the entire body up) it looks strange because of the position:fixed on the gradient div. Note that this is only a problem when the content div is smaller than the viewport. If the content div is larger than the viewport it pushes the gradient out of view and works great.
Is there any way to prevent the iPad from moving the body around like that or is there a better way to implement this functionality without using position: fixed?
Thanks!
Can you explain a bit more what looks wrong on the iPad, I don't have one with me. Also, I removed the position: fixed; and the functionality didn't change on chrome. position static and relative work the same for me.
I abandoned the gradient div and instead set a min-height on the content div with a background image of the gradient with the following properties:
#content {
min-height: 200px;
background-color: white;
background-image: url(../Images/content-background.png);
background-position: center bottom;
background-repeat: repeat-x;
}
I have a webpage with a static CSS background, but the content is longer than the height of the image. This causes whitespace at the bottom after the image ends.
How can I make the image scroll along with the view of the user's screen?
background-attachment: fixed;
See http://meyerweb.com/eric/css/edge/complexspiral/demo.html for a more detailed example.
I've been given a design for a website, and am trying to implement it.
One problem I've run into is that the design has some background images (one for the header, one for the body, and one for the footer of the site) that are wider than the main content area of the site.
Simply putting them in as background images doesn't work, since expanding the header, body and footer divs enough to accommodate the backgrounds causes horizontal scrollbars to appear if the browser window is not big enough to fully show the backgrounds.
This is undesirable since the backgrounds are not really important for viewing the website, and I don't want scrollbars to appear for them (scrollbars should only appear once the browser is too small to completely show the content of the website).
The second technique is to have a separate, absolutely positioned div to show the header background image (and put it under an element with the browser window's size), and set its width to 100% so that it never exceeds the size of the browser window (and hence create scrollbars).
This works up to a point - however, when the window is too small, the background starts shifting around relative to the content since the "top center" position of the background is relative to the browser window, not the content area. At large sizes, these are effectively the same since the content area is centered, but at small sizes, only part of the content is shown, so the center of the content and the center of the browser window are different.
A good illustration of this problem that I've found is the Quicken website: http://quicken.intuit.com/. At large sizes, its cloud background looks fine, but if you make your window's width small enough, the clouds start shifting relative to the content (bad!).
Any ideas on how to fix this so that backgrounds images
don't create scrollbars since they are not part of the content of the site
are fixed relative to the content of the site (and don't shift around at small browser window sizes)
?
An ideal solution would be something like turning overflow to hidden on the body, but only for specified divs. Unfortunately I believe this is impossible.
I'd prefer a pure html/css solution, but I accept that I may need js to get the effect I want.
Thanks! (this is a complex issue, so if any clarification is needed, let me know)
UPDATE: Fixed this by setting min-width on the background div to the width of the content.
Set the min-width on the div containing the background image to the width of the content.
You need to have your header, content & footer have a width of 100%. And put the image in as a background image in these divs ... center it horizontally.
Inside the specific divs have a wrapper that is centered. and is the width of the content of them divs.
Like so.
HTML
<div id="header">
<div class="wrapper">
...
</div>
</div>
<div id="content">
<div class="wrapper">
...
</div>
</div>
<div id="footer">
<div class="wrapper">
...
</div>
</div>
CSS
div#header {
background: url(...) 50% 0; /* to center your background image horizontally */
}
div#content {
background: url(...) 50% 0; /* to center your background image horizontally */
}
div#footer {
background: url(...) 50% 0; /* to center your background image horizontally */
}
div.wrapper {
margin: 0 auto; /* to center the div horizontally */
width: 960px; /* or however wide it should be */
}
Hope this helps.
Am I missing something, or should you be using the CSS background-image property?
I had a look at the Quicken site, and to be honest the cloud background image shifting when the browser is resized shouldn't be worried about unless your background-image is most distinctive than a bunch of clouds.
See what I mean?
You could use the overflow property and set it to hidden on the div that cause a scrollbars to appear.
I had the same issue on a site that I worked on, and come up with the following solution, which works well if all your background images are the same width.
/*
A container div that is set to the 100% width, with the overflow set to hidden.
This hides the overflowing images if the window sizes is too small
*/
#bg_container {
position:absolute;
z-index:0;
top:0px;
width:100%;
overflow:hidden;
}
/*
A div that sets the size of the content and centers itself on the page.
*/
.bg {
margin:0 auto;
width:1000px; /* content size */
overflow:visible;
}
/*
Here I set the image away from the left edge of the div to center it to the content. The actual size of the image is 1500px.
*/
.bg img {
margin-left:-250px;
}
