Placing a div sidebar next to a centered div - css

I've found a lot of variations to this question within SO, but it seems no matter what I try I can't get this (seemingly very simple!) thing working!
What I'm trying to do is to keep the 'centered' div in the center of the viewport and to place the 'sidebar' div directly to its right (i.e. not right-aligned to the viewport) without affecting the centering of the 'centered' div.
Here's some test code on jsfiddle:
http://jsfiddle.net/6wCyr/13/
Everything I've read seems to imply that the float property is exactly what I'm looking for, but the results in the link show that I get weird results wherein the right sidebar is placed below the 'centered' div rather than beside it. That's what's shown in the link.
I've also seen a solution involving using a negative value for the right property, and setting the width of the sidebar exactly, but I couldn't get that one going either.
Hopefully this question is as easy to solve as I think it should be! Just can't seem to find the right set of div inside div and so forth. Hard to debug these alignment issues!
Thanks!

Live Demo
I moved div.sidebar inside div.centered.
I added position: relative to div.centered.
We're using this technique.
You don't have to declare a fixed width on div.sidebar.
CSS:
div.centered {
margin-left: auto;
margin-right: auto;
border: dashed;
width: 100px;
height: 100px;
position: relative
}
div.sidebar {
border: dotted;
position: absolute;
top: 0;
left: 100%
}
HTML:
<div class="holder">
<div class="centered">
CENTERED
<div class="sidebar">
RIGHT SIDEBAR
</div>
</div>
</div>

Try this.
http://jsfiddle.net/DOSBeats/6wCyr/16/
.holder {
margin:0 auto;
width:100px;
}
.centered {
border: dashed;
float:left;
height: 100px;
}
.sidebar {
border: dotted;
float:left;
margin-right:-100px;
width:100px;
}

If you do not set a width to your holder and center it, the sidebar will float to the edge of the window.
Try this:
HTML:
<div id="holder">
<div id="sidebar">Sidebar</div>
<div id="centered">Centered</div>
</div>
CSS:
#holder{
margin:auto;
width:500px;
}
#sidebar{
border:dotted;
float:left;
width:100px;
}
#centered{
border:dashed;
margin-left:110px;
width:380px;
}

Positioning a div within a parent div using auto margin or %

I was under the impression that when using % or auto for margins on a div contained within another div the position would be calculated in respect to the parent div.
So if I have a div with height: 50%, margin-top: 25% and margin-bottom: 25% the box should centre vertically within the parent div.
When I do this though the div centres on the page not the parent div.
The CSS
div#header {
width: 100%;
height: 100px;
margin: 0px;
position: fixed;
}
div#leftnavigation {
height: 50%;
margin-top: 25%;
margin-bottom: 25%;
float: left;
}
And the HTML
<!--Title and navigation bar-->
<div id='header'>
<!--Left navigation container-->
<div id='leftnavigation'>
<p>efwfwgwegwegweg</p>
</div>
</div>
In my case there are other divs floated to the right of the one detailed above, but any one of them behaves the same way. I'm assuming I'm doing something daft but I've been over all the other questions I could find along these lines and still can't figure it out.
EDIT
Here's the JSFiddle as requested http://jsfiddle.net/ChtVv/
UPDATE
I've tried removing the margin constraints and setting the leftnavigation div to height: 100%, this works so the issue is with the margin attribute?
The reason it didn't work is that percentage-margins are percentages of the parent's width, not its height. You can tell this by using margin-top: 25px; margin-bottom: 25px;, and also by increasing the width of the right-panel in jsFiddle.
In all cases % (percentage) is a valid value, but needs to be used
with care; such values are calculated as a proportion of the parent
element’s width, and careless provision of values might have
unintended consequences.

CSS is tricky!! :D
This is a borrowed technique to centre vertically and horizontally, but it would involve changing your HTML and CSS. I am not sure how flexible you are with your code:
CSS:
#outer {width: 100%; border: 3px solid red;}
#middle {width: 100%; text-align: center;border: 3px solid green;}
#inner {width: 200px; margin-left: auto; margin-right: auto; text-align: left;border: 3px solid blue;}
/* Courtesy: http://www.jakpsatweb.cz/css/css-vertical-center-solution.html */
HTML
<!--Title and navigation bar-->
<div id='outer'>
<!--Left navigation container-->
<div id='middle'>
<p id="inner">efwfwgwegwegweg</p>
</div>
</div>
You can build upon this to achieve whatever you are after!

Ok, so there are a lot of reasons why this would not work.
The main reason would be that your container has position:fixed;
When adding position:fixed; to a element, it no longer reserved it's space in the DOM and won't contain it's children.
I have made a example of the best way (in my Opinion) to center your child both Vertically & Horizontally
Here is a demo.

And here is the code.
<div id="container">
<div id="child"></div>
</div>
#container{
width:100%;
height:500px;
background:#CCC;
margin:0;
}
#child{
width:50%;
height:50%;
background:#EEE;
position:relative;
top:25%;
left:25%;
}

How to add a footer which always shows up at the bottom of the page

I'm looking for a way to add a footer to my page which will always show up at the bottom. The problem is, a lot of the content on the page is set via position: absolute;, so at the moment, unless I manually give the footer a margin-top: 900px; value, its simply hidden by one of the absolute positioned content. But on some pages where the content is less than 900px, there is an unnecessary gap at the bottom between the end of the page, and the footer.
How can I resolve this in such a way that there's no gap between the end of content and footer?
In the new jquery, you can just use this:
<div data-role="footer" data-position="fixed">
<h1>Fixed Footer!</h1>
</div>
from http://jquerymobile.com/demos/1.2.0/docs/toolbars/bars-fixed.html
Put everything before the footer in a div with position relative. This div will flex vertically to the content in it and will provide the buffer to keep anything after it right below it. No margin needed.
You also can put indexes.
z-index: 1;
http://www.fiveminuteargument.com/fixed-position-z-index
In your case, put z-index in css for footer at 10 or more.
Let's suppose a <footer>, styled with display: block and height: 250px.
So all you have to do to achieve what you want is add:
position: fixed;
top: 100%;
margin-top: -250px;
That's it. It'll be permanently aligned at the bottom. :)
Sticky footer. No javascript required:
http://www.cssstickyfooter.com/
After doing some fiddling I was reminded that absolute positioning removes the element from the document flow. You cannot depend on an absolute positioned element to affect the other elements because it will not. Because you do not know the height of the content then using margin-top is clearly not option.
So I came up with this: basically do a normal layout with floats then use position relative to move the items where you want them. This way the elements still affect the document flow, however, now you have total control over the position. This is precisely what relative positioning is for: You want total control over the position of an element but you still want they element to affect the layout normally.

Image Placement Issues

I''m looking to move an image of a saw in between two borders so it is looks likes this.
I believe I have centered the image correctly but it appears I haven't and I am loathe to use padding if that is not right way, as I want this to be semantic as possible for a responsive design. I also need it to be placed within the two borders with one border stacked in front. Presumably I need use z-index to do that but I haven't got that far.
JsFiddle
Are you looking for something like this:
See Demo: http://jsfiddle.net/rathoreahsan/Fcn96/
Hi Played with positioning and tried to make the results as per your referred image requirement. I hope this will help you.
CSS
#logo-container .saw {
left: 50%;
margin: 0 auto;
position: relative;
top: 46px;
}
#tag-container {
border: 2px solid #00AC9D;
height: 150px;
margin-bottom: 5px;
position: relative;
width: 1140px;
}
see the demo:- http://jsfiddle.net/RJVXE/16/
You need to utilize both z-index and positioning.
.line
{
height:1px;
width:100%;
background:#000;
position:absolute;
left:0px;
}
.item1
{
top:5px;
z-index:5;
}
.item3
{
top:25px;
z-index:15;
}
<div style="width:100%; position:relative">
<div class="line item1"></div>
<div style="position:absolute; top:0px;left:50px;z-index:10">
<img src="saw.png" />
</div>
<div class="line item3"></div>
</div>
(example uses both inline & blocked CSS references only for brevity. Stay away from inline CSS).
You could tryo what AlphaMale suggestes here: How to center image in a div horizontally and vertically
Before your image include a 'span' tag. Then add this properties to 'saw' class:
#logo-container .saw {
text-align: center;
margin-bottom:-50px!important;
}
The !important is to override margin: 0 auto that actually has.

How to have "margin:auto" and "margin-left:offset" working together?

I have a container on my test site:
#container {
margin: 0 auto;
}
Then I added the left vertical menu and on some small screens that menu is not fully visible.
Like my old laptop :-)
I want to keep the margin:auto setting in place but I want to move the whole #container a little bit to the right.
Could it be done some how?
I have tried #container {margin-left:10px;}, but to no avail.
Playing with firebug, it's good to use:
#container {
margin: 0 auto;
position:relative;
left:10px;
}
Hope it solves...
The simplest approach would be to introduce another element (or style another element if it's already available). Thus, you might have:
<div style="margin-left: 10px;">
<div id="container" style="margin: auto;">...</div>
</div>
That way the centering is being done within a container div that's already got the appropriate left-hand padding.
If you wrap your #container div in another div with double the left margin, that will work.
#wrap {
margin-left: 20px;
}
.centre { /* this would be your #container */
width: 100px;
height: 40px;
margin: auto;
background-color: #f00;
}
#wrap .centre {
background-color: #00f;
}
The HTML:
<div class="centre"></div>
<div id="wrap">
<div class="centre"></div>
</div>

HTML/CSS Div placing

Yo. There's a tendency in placing divs to follow each other vertically, but what i'm trying to accomplish right now is to is basically to place a number of divs (two) inside a parent div like so:
<div id='parent'><div id='onediv'></div> <div id='anotherone'></div> </div>
And i'd like to place 'anotherone' just to the right of 'onediv'. Sadly, float:right is pretty much ruining the layout with the divs popping out of their parent divs and whatnot. Any suggestions are welcome.
Edit: It might be worth noting that the parent div and 'anotherone' has no height elements at all, with 'onediv' planned to be thought as the "height support" div, allowing the contents of 'anotherone' to make the parent div larger at will.
Edit again: Here's the CSS for the specified stuff:
.parent
{
width: 90%;
margin: 0 auto;
border:solid black 1px;
}
.firstchild
{
width: 20%;
margin: 5px;
border: solid black 1px;
height: 180px;
}
.secondchild
{
width: 60%;
border:solid black 1px;
margin: 5px;
}
You can float both inner divs and give the outer div an overflow so that it grows with the inner divs.
Example:
#parent {
overflow: hidden;
}
#parent div {
width: 50%;
float: left;
}
Try this:
<div id="parent">
<div id="onediv" style="float:left;"></div>
<div id="anotherone" style="float:left;"></div>
<div style="clear:both;"></div>
</div>
I think this is what you want (note the re-ordering of DOM elements):
<div id="parent">
<div id="anotherone"></div>
<div id="onediv"></div>
</div>
/*CSS*/
#anotherone{
float:right;
width:50%;
}
#onediv{
float:left;
width:50%;
}
Note, if this is what you want, IE6 will still mess it up. ;-)
You certainly need to specify a width as indicated in #Kevin's answer to get the layout you described, simply specifying float left/right will not have the desired effect. Try specifying the width in pixels rather than a percentage. Failing that or if that's not appropriate for you, I think you possibly need to specify the width of the outer div (through css if you like).
#onediv { float: left; width: 50%; } #anotherone { float: right; width: 50%; }
Just use the <span> tag. Its the equivalent of except it doesn't start a new row.
