I'm trying to stack a few divs vertically that have a "red" background which takes 100% of the page. Inside those divs i make 960px centered divs. What happens is very strange: if i resize my window to be less than 960px (for scrollbar to appear) - there is a gap at the right side of each stacked div. You can view live example here: http://jsfiddle.net/GLE7A/
Basic code:
<style type="text/css">
* { padding: 0; margin: 0; border: 0; }
.wmain { background: red; }
.w960 { margin: 0 auto; width: 960px; }
</style>
<div class="wmain">
<div class="w960">
test
</div>
</div>
<div class="wmain">
<div class="w960">
test
</div>
</div>
Solution is easy: just add min-width:960px; to the .wmain div to fix the problem
QUESTION: why does this strange behaviour happen in the first place? Does a fixed-width child somehow escapes normal flow like absolutely positioned divs or smth.?
Thanks for your thoughts
That occurs because you dont define any width for the wmain div that is what confusing the browsers.

I have quite an annoying problem, for which I don't seem to be able to find an easy fix. Consider the following HTML:
<html>
<body>
<div id="page">
<!-- Some HTML here -->
<div id="menu"><!-- Some stuff here --></div>
<!-- Some HTML here -->
</div>
</body>
</html>
With the following CSS:
body {
text-align: center;
}
#page {
margin: 0px auto;
max-width: 1200px;
}
#menu {
width: 100%;
padding: 0px 2000px;
margin-left: -2000px;
}
This would give a centered page div, with a menu bar in there. Thing is, whenever the browser width becomes > 1200px, the div will not grow any further, but the menu div must at all times stretch all the way to the window edges. And the problem with this approach now is, that I get a horizontal scrollbar because the menubar is bigger than the screen. So, I am looking for a solution for this. Something that disables the scrollbar from having impact on the horizontal scrollbar would do. Disabling the horizontal scrollbar isn't an option however, since the content must be scrollable on small devices as well...
I am aware that I could fix this by pulling the menu bar outside of the page div, but that is hard, since I am editing a Drupal theme and I want this change to have as little impact as possible.
Thanks in advance for any suggestions!
What you mean is that you want the div to stay 100% width all the way but to have scrolling inside of it? If so then you should have a wider div inside the main div.
Something like this-
<div id="full-width">
<div id="scrolling-div">
</div>
</div>
<style type="text/css">
#full-width {
float:left;
width:100%;
height:500px;
overflow-x:visible;
}
#scrolling-div {
float:left;
width:300%;
height:500px;
}
</style>
I tested this code, it works :)
You can easy fix this by setting your html and body styling like this:
html, body {
overflow-x:hidden;
}
body {
margin: 0;
}
This should do it with the current code you have now.
Can anyone enlighten me to why the following occurs with this test case?
<!DOCTYPE html>
<html>
<head>
<style>
body {
background-color: #ffffff;
margin: 0;
padding: 0;
}
.section {
background-color: #000000;
color: #ffffff;
}
.wrap {
width: 960px;
margin: 0 auto;
}
</style>
</head>
<body>
<div class="section">
<div class="wrap">Some content here</div>
</div>
</body>
</html>
When the window is big enough to accommodate 960px, everything works as expected.
When the window is resized to smaller than 960px a horizontal scrollbar appears (As expected). However, when scrolling horizontally it appears that the .section div has not been stretched across the document and appears only to be the width of the window, therefore revealing the body's white background.
I would normally expect the black, .section div to stretch across the document since it's display: block by default.
Does anyone know why this is happening and more importantly, how to get the result I expect?
Cheers
It's because the witdth of your section is only as big as what's in it. In this case this means your wrapper which is set to 960px. Setting the section in percentage only works as percentage of the available screen, so width:100% wouldn't solve this. You should set your section width to a specific number and that would fix the issue.
Edit: Use min-width instead of width and it works even better for when you go bigger than you min-width.
section is sizing to it's contents, try setting width:100% on .section
In addition, you may want to add this to .wrap
margin-left:auto;
margin-right:auto;
that will center the wrap div
I want to add space in the HTML document like the ones inside the orange rectangle. I don't know the technical term for what it's professionally called. Apologies.
If you are looking to center your web page and you are using a fixed width on your main container this can easily be achieved.
CSS
.container {
margin:0 auto; /* this will center the page */
width:960px; /* use your width here */
}
HTML
<body>
<div class="container">
<!-- all your great content here -->
</div>
</body>
If you need help applying this to your html/css please post your html and I would be glad to help you.
Why not do this? :
<style type="text/css">
html, body {
margin: 0;
border: 0;
width: 100%;
}
body {
padding: 0 20px;
}
#main {
margin: 0 auto; /* in case you want to set a fixed width on this as well */
}
</style>
<body>
<div id="main"></div>
</body>
This way, depending on the width on the window, the main div will resize and there will always be a fixed space on both sides. If you want the main div have a fixed width and the spacing on the sides to be resized automatically, use the other solutions.
Those would be margins. But your better option would be to wrap the main area in a div or other block element/sectioning root, set it to the width that you want, and then center it with margin: 0 auto;
you need margins. set the style to margin:0 auto; that will center your div
I want to recreate the following header:
The problem is that the content is centered in the white section. Grey is the background of body and the header is 100% of screen.
What I have now is:
CSS
.top_left {
background:#3c4d74;
}
.top_right {
background:#2f3a5a;
}
.top_center {
background:#3c4d74 url(http://img85.imageshack.us/img85/2816/headerbgo.jpg) no-repeat right top;
height:140px;
}
#page,
.top_center {
max-width:1000px;
margin:0 auto;
}
#page {
background:#FFF;
}
body {
background:#DEDEDE;
}
HTML
<body>
<div id="top-header">
<div class="top_left"></div>
<div class="top_center">
LOGO
</div>
<div class="top_right"></div>
</div>
<div id="page" class="hfeed">
MY content bla bla bla
</div>
</body>
Which you can see working on http://jsfiddle.net/gTnxX/ (I put max width 600px instead of 1000px so you can see it on fiddle).
How can I make the left side soft blue and right side hard blue at any resolution?
To do this you need to be very aware of how positioning works.
The #header-bg is positioned so it falls below #wrapper. It is 100% width, 140px high with 2 divs which both take up 50% of that space and they both get a different colour for left/right.
The #wrapper is relatively positioned to make z-index work, putting it above the #header-bg. Width is set at 600px, and margin: 0 auto; centers it.
The #header is a simple div which has a height set to it and the background it requires.
Content follows the #header in normal flow.
Here is a jsfiddle with the requested behaviour.
http://jsfiddle.net/sg3s/cRZxN/
This even degrades nicely and lets you scroll horizontally if the content is larger than the screen (something I noticed from the original jsfiddle).
Edit:
To make it IE7 compatible I made some changes to fix 2 bugs. I had to add left: 0; and top: 0; explicitly to #header-bg to fix a positioning bug. Made the divs inside #header-bg 49% instead of 50% or else IE7 would not resize them properly and make the right div bump down. To compensate for the small gap that created I made the right div float: right;.
I have the following HTML and CSS:
<div class="content">
<div class="leftbg"></div>
<div class="innercontent"><p>Some content goes here</p></div>
<div class="rightbg"></div>
</div>
.content {
overflow: hidden;
}
.leftbg {
background: url("./leftbg.png") repeat-y scroll top left transparent;
margin-left: 0;
float: left;
width: 10px;
}
.innercontent {
width: 600px;
float: left;
margin-left: 0;
}
.rightbg { /* similar to left bg except for the right side */ }
The problem that I am having is the leftbg image is only repeating until it reaches the height of the paragraph in the innercontent div. I am accessing a database to grab the content for the innercontent div and hence the content will be of variable height. Is there any way to make it so that it repeats until it reaches the bottom of the leftbg (and rightbg) div? What I mean by that is for it to repeat until it is at the bottom of the innercontent div without setting the height as static (e.g. height: 200px;) because the height will be variable.
This equal height column layout tutorial from smashing magazine might help you. With lot of explanation of all the whys.
I think the problem you are facing is that leftbg and rightbg don't have any content. The height of the <div class="content"> element equals the height of it's "tallest" child (innercontent in this case).
Maybe if you post a mockup of what you want as a final result I can help you further. Also, the markup would be helpful.
