I've been working on a website with a pretty standard layout, header, content, footer, each being a DIV with a 900px width inside of a page-wide DIV, just like the one described in this question:
Full width background, without a wrapper
Now the problem itself is that whenever the browser window becomes less wide than the specified DIV width (900px) the background of the wrapper seems to disappear, showing the background color of the website itself. This also happens while using the code in the aforementioned question.
This is the CSS code:
#headerwrapper {
height: 229px;
background: url(imagenes/header.gif);
background-repeat: repeat;}
#header {
width:900px;
height:229px;
padding:0px;
margin:0 auto;
}
And this one is the HTML code:
<div id="headerwrapper">
<div id="header">
Content goes here.
</div>
</div>
Any suggestions are appreciated.
you probably can't see the background in the scrollarea. You need to set min-width: 900px; or max-width: 900px; so that the background will be shown in the scrollarea.
If you do not specify width for the #headerwrapper, browser makes it 100% of parent container (div or body). So if width of view area is less than 900px - #header becomes wider than #headerwrapper, so background is not showed for overlapped part. You may add overflow:auto; to #headerwrapper so scrollbars will appear, but i do not think that is a solution. So it is better to add background for the #header or add min-width for #headerwrapper.
P.S. Specifying
min-width:900px;
width:auto !important;
for #headerwrapper should do the trick.

I have running always into the problem with the responsive images,and i did not find an answer to clarify the problem.
The problem is with image
image {
height:auto;
width:100%;
}
when i add a simple image and style it, it works. when i start a project more complex with a lot of divs and I set the same properties doesn't work anymore. What's the purest explanation for this.
This is because when you add the <img> to the html directly, the browser sets the height of the element to the height of the image you provided (unless otherwise specified). When you add the image as a background of a <div> and set the height to auto, it tries to size the div to the height of the content. However, in this case, there is no content -- only a background that will be the background once the div has some height. An empty div has no height. Therefore, if you want the image to be the background of the <div>, it must either contain some content, or have its height set manually.
I'm using centered imgs to act as backgrounds for some tiles. I'm trying to have these images scale with their parent div's height and if they are wider then their parent's for them to hide the overflow.
Example:
* I've got it working now. Answers are below, I'm updating this code to display all I needed to use to get it to work *
HTML
<div class="container">
<img class="derp" src="http://gridiculo.us/images/kitty02.jpg">
</div>
CSS:
.container {
height:250px;
width:50%;
}
.derp{
object-fit: cover;
height: 100%;
width: 100%;
}
Here's a near-example: http://codepen.io/chriscoyier/pen/myPMGB
The difference would be that I'm using s and not background-image, and that instead of the img filling the div completely it would fit to the height and hide the width overflow.
I'm trying to avoid using background-image since I'm using a lot of these tiles and making CSS rules for every one isn't going to work.
In order to scale it with the div's height, I'd change the height from px to % - this way, the larger's the div, the larger's the picture. In order to certain the image, i'd use margin in the image css. That'd look like so:
.derp{
height:80%;
width:80%;
margin:10%;
}
.container {
height:250px;
width:50%; /* needed */
/* inner img is centered horizontally */
vertical-align:top;
text-align:center;
overflow-x:hidden;
}
<div class="container" style="background-color:gray"> <!-- The background is there so you could see the image relative to the div -->
<img class="derp" src="http://gridiculo.us/images/kitty02.jpg">
</div>
The best way to keep the aspect ratio of the image is to set the width to auto (and it's the default behavior so you don't need to set explicitly). And with a simple overflow:hidden it works almost as you want it.
The hard part is centering horizontally. You can try this answer :css to center a image horizontally.
However if all your images aren't the same size, you will need to make one rule per image. And in this case putting the image as background-img would be better for semantic and accessibility (because your image doesn't have a sense in the page, it doesn't convey any information, it's decoration). An <img> would be read by a screen reader (the alt attribute), and in your case it wouldn't help a blind people.
Depending on how many browsers you need to support, I'd suggest you use object-fit! Support for it is okay if you can ignore IE, but in case your project qualifies, I see no problem with using it today. Also, there is always a polyfill.
You can find a nice summary on CSS-Tricks.com about the property. It basically works similarly to background-size, but for <img> tags. In your case, object-fit: cover; does the trick.
I made a little demo on CodePen that shows you how it works.
img {
height: 100%;
object-fit: fill;
width: 100%;
}
Have a look at, http://thomaspalumbo.com
I have this CSS for my website's container:
.graybox {
padding: 0 30px 30px 30px;
background: #ededed;
position:absolute;
left:0;
right:0;
}
Then I have a container on top of that to center that info.
The .graybox container spreads the width of the page like I want but now my footer div is hidden, according to firebug is it actually behind? And up on the page?
Is there a fix for this?
While I'm here can anyone explain the white space on the right side of the page. It comes into effect once the page is resized smaller.
You can use the CSS z-index property to make sure your footer is in front of the content. Z-index only works when the element is positioned though. So make sure you add position:relative to your footer
#footer{
position:relative;
z-index:999;
}

EDIT
Just checked out the code of your website, and I don't understand why your graybox is positioned absolutely, this will only make things more complex. The same goes for your menu, why position it absolute, why not just add it in the right order in the HTML in the first place?
EDIT
If you want to center your content but with a background that has a 100% width then you can simply add a container div like so:
HTML
<div class="container">
<div>lorem ipsum....</div>
</div>
CSS
.container{
background:red;
}
.container div{
width:400px;
margin:0 auto;
background:yellow;
}
See JSFiddle here: http://jsfiddle.net/HxBnF/
Currently you cannot do this because you have a container which you set at 980px, don't ever do that unless you are sure you don't want anything to wrap over it, like in this case the background of a div in that container.
in the div style, just assign a z-index value greater than any other z-index such as
.divClass{
position: absolute;
z-index: 1 //if other elements are still visible chose a higher value such as 20 or even higher.
}
I have a centered wrapper with following CSS:
div.wrapper {
width: 1170px;
padding-left:30px;
margin-top: 80px;
margin-bottom:20px;
margin-left: auto;
margin-right: auto;
position:relative;
background-color:black; }
inside i have a div with following css:
position:absolute;
top:-26px;
left:517px;
height:63px;
z-index:3;
inside of this div is an image which has 759px width, that makes the wrapper grow larger and makes the browser show a v-scrollbar on lower display resolutions.
what i want is to make the image go outside the wrapper but prevent the browser from showing the scrollbar, so that the right side of the image is only shown if your browser window is large enough and the wrapper keeps its 1200px width. i can't make it a background image because it goes over some of the other content.
something that is compatible with >= IE7 would be nice.
i uploaded a pic of the page to show what i mean:
http://img153.imageshack.us/img153/6070/hpx.jpg
the blue box is the wrapper, it has 1200px width and is ALWAYS centered in the window (unless then window is smaller than 1200px, then it scrolls)
the red box is the image (the green bar is not part of it)
You can set overflow: hidden to the wrapper so that content that exceeds the dimensions of wrapper will not be shown.
see overflow
You are looking for #your_div { overflow: hidden; }, if you want your content to be hidden. Or #your_div { overflow: visible; } if you want your content visible outside the div.
The only method that springs to mind given your requirements is to move the inner element out of that wrapper div and position it in relation to the entire window:
<body>
<div class="abs">the div with the image</div>
<div class="wrapper">the wrapper div</div>
</body>
Unfortunately, this probably means you can't position it very well. You may need to use Javascript to get the width/height of the page and/or the position of the wrapper div, and calculate the offset accordingly. (You'll find questions on Stack Overflow for these bits.)
The problem lies with the img being inline. Not tested but you should 'display:block' the image and then float it or absolutely position it.
I have a div with two nested divs inside, the (float:left) one is the menu bar, and the right (float:right) should display whatever content the page has, it works fine when the window is at a maximum, but when i resize it the content is collapsed until it can no longer has any space, at which it is forced to be displayed BELOW the left menu bar, how can I make the width fixed so that the user may scroll when resized?
(css width didn't work, i alternated between floating the right content and not), here is the code:
<div style="width:100%">
<div style="float:left; background:#f5f5f5; border-right:1px solid black; height:170%; width:120px;"></div>
<div style="margin-right:2px;margin-top:15px; margin-bottom:5px; width:100%; border:1px solid #f5f5f5"></div>
</div>
I only need to have this working on Interner Explorer for now.
This should do it (container is the parent div containing that 2 divs):
.container {
width: 1024px;
display: block;
}
You may want to set a width on the containing div and set your overflow property
#containing_div {
width: 200px;
overflow: auto;
}
Also use the min-width property on the page if that makes sense, however that CSS property doesn't really work with IE6, this is usually what I do in that situation (supporting Firefox, IE7, IE6, etc)
#container {
min-width: 1000px;
_width: 1000px; /* This property is only read by IE6, which gives a fixed width */
}
Well, putting a width or min-width property is the way to go.
Now, without an example, or a link of the actual page, it's a bit tricky to answer.
Simply don't make the right div floating. Menu is already floating left of any other content. Just set a left-margin for the right div so the content in that div won't be wrapped around the floating div.
if the two divs are taking up 100% of the available width, could try to use percentage width and display: inline with a further div with a fixed min-width/width (boo IE) inside where required.
this is rather difficult without some HTML to go on
Your containing div should have a width wide enough to contain both inner div's
So if your two inner div's are 300px each and assuming you have no margin/padding on them then you should set the outer div to be 600px;
I'm a bit confused:
Fixed width means the width of a node will not change. Never.
You say you want to scroll when the screen gets too small for your content, so I think you mean the exact oposite of fixed width.
If my assumption is right, you could as mentioned before go for the percentual widths.
Watch out width the suggested "min-width" solution because it is not supported all that well.
<div id="container" style="width:100%">
<div id="primaryNav" style="float:left; width:150px; background-color: Orange">someNav</div>
<div id="content" style="margin-left: 10px; background-color: Red; overflow: auto;">
