Right now I have a main div with an id of "wrapper", and inside this div I am trying to make two other divs that take up about the entire width of "wrapper". The first div, "sidebar", is narrow and contains some information I want displayed on the far right of "wrapper". The second internal div I have will be dynamically updated using php and javascript from data inserted by users, id called "maincontent".
I can get them positioned inside "wrapper" fine at first. The problem comes when new content is added in the "maincontent" div. When new content is added the "sidebar" div will move down proportionally to the height of the newly added content.
So, my question is this:
How do I get the two internal divs to maintain their positions on the top of the page while still being able to extend dynamically downward without anything moving around?
you need to float:left your left-content:
see the css below:
.wrapper
{
margin:0;
padding:0;
top:10px;
width:100%;
height:500px;
background-color:yellow;
}
.left-content
{
position:relative;
width:20%;
background-color:red;
height:100%;
float:left;
}
.main-content
{
position:relative;
width:80%;
left:20%;
background-color:green;
height:100%;
}
where your divs are as below:
<body>
<div class="wrapper">
<div class="left-content">
</div>
<div class="main-content">
</div>
</div>
</body>
what's important is, you accurately divide the width of the parent to the child containers
i.e. total width of child containers <= parent width
see, you need to learn about position attribute of css-style
when you do position:relative for any container, css properties like top, left,right,bottom starts working for them.
Check out my fiddle, the Javascript is completely unnecessary. Let me know if it helps you, or if you have any questions left. The most important part is having float: left or float: right in both the maincontent and sidebar.

I am trying to add two divs inside the parent div, which has a button inside each div.
I need to fix the width in pixels only for the second div and the 1st div should be having width in % so that the button inside the 1st div should be covering the entire space of the browser.
I need all the widths in % and also I don't want to change either html structure and css because it is already implemented so i just need changes in css property.
Here is my demo
http://jsfiddle.net/zuyyT/2/
P.S : When I scale the browser, the second div is coming in next line. Please scale it and check once.
Fiddle is working on and off ... you can go either one of two ways; using floats (need to change the order of your markup) or positioning - like such ...
<div class="block">
<div class="block_right"> <span>last button</span> </div>
<div class="block_left"><a href="" class="scButton score" > <span>Lorem ipsum</span></a></div>
</div>
and your CSS ...
.block {
display:block; background-color:#FFC; width:100%; float:left; height:30px
}
.block_left{
background-color:#C93; margin-right: 150px;
}
.block_left a{
background-color:#CCC; border-radius:4px; padding:4px; width:100%; display:block
}
.block_right{
float:right; width:130px; background-color:#CC9
}
... using position, you'll need to add position:relative to .block and then right:0 to .block_right; keep the margin on .block_left
Using positioning, you won't need to change the order of the elements in your markup (should that be an issue).
This may be what you require. :-)
.block_right{
position :absolute;
right:0;
top:0;
float:right; width:130px; background-color:#CC9
}
If you give your block_left a width:100% and then use margin-right:-130px; you can leave your html exactly as it is.
The negative right margin leaves space on the right hand side for other elements to fit into even though the element has a 100% width.
This is happening because of the width of right div..u gave 100% to the parent and 80% to the first child..so,when the browser size is 500px(say),the first child will occupy 400px(80%) of it...And when u give 130 px to the second child,it'll come to the next line..that's pretty obvious coz it doesn't have enough space in the first line...so it should be <=100px(for this example)...
Appologies for a duplicate question, but none of the answers to the other questions seem to fix my problem. I would like to align a div in the center of the page. The div must only be as wide as the content inside it. It will be used as a modal popup. I have setup a jsFiddle here: http://jsfiddle.net/PDzNj/11/
The div aligns its left side in the middle and not the center of the div (which is the desired effect)
Thank you in advance for any help
One option is to emulate a table with the <div>'s surroundings.
<div class='outer'>
<div class='inner'>
<div class='thebox'>Contents</div>
</div>
</div>
And then use the CSS:
div.outer {
display:table;
width:100%; //Or however wide you want the container to be
}
div.inner {
display:table-cell; //This allows the use of vertical-align
vertical-align:middle;
text-align:center;
width:100%;
}
div.thebox { //Your variable-width container
display:inline-block; //Makes it obey text-aligning.
}
You can of course add height values as needed. This is neater, CSS wise, than making it relative, or using margins, and also disrupts the surroundings less.
I currently have a div with width:auto to fill the entire screen width but I want to put a side bar on the right hand side.
When I float the width:auto div left and fixed width div to the right it goes under instead.
I'm basically looking for something similar to what reddit have with there search bar on the right width the content auto adjusting to the page width.
Thanks
You can make it like this:
Say you have those 2 divs inside a parent container, which expands to fit the page:
<div id="container">
<div id="autowidth">text expands her...</div>
<div id="fixed">This is a fixed column</div>
</div>
In your CSS:
#container {
width:100%;
border:1px solid black;
padding-right:200px;
}
#autowidth{
width:100%;
background-color:red;
float:left;
}
#fixed{
width:200px;
background-color:green;
float:right;
margin-right:-200px;
}
Basically, the parent container holds everything together. It has a padding of 200px (the width of the right col), so that its content doesnt goes beyond that point. In turn, the right col has a margin of -200px, so that it forces the boundaries imposed by the parent padding and places itself always at the foremost right. The other div, actually, now has only the spaces provided by the parent container, constrained by its padding, so its 100% would be, in fact, (100% - (parent's padding)). You can see a working result of this here: jsfiddle.
I'm pretty sure there might be more elegant solutions out there, so bear with me.
if you want to give a background, like it were 2 cols, you can go for the classical 'faux columns' background (see example at a list apart )
You don't strictly need a container div. I did css inline for brevity.
<div style="float:right; width:14em; background-color:#CCC;">
<p>This div is fixed-width.</p>
</div>
<div style="background-color:#EEE; margin-right:14.5em;">
<p>This div is auto-width.</p>
</div>
The answer doesn't work for me, I think it's outdated. Now you have to specify box-sizing: border-box for padding to count to width, but thanks for inspiration. This is my solution.
#autowidth {
float:left;
width:100%;
padding-right:200px;
box-sizing:border-box;
}
#fixed {
float:right;
width:200px;
margin-left:-200px;
}
Just checking to see whether there's a way to do this in CSS before I get my Javascript on!
In the example, the #fixed div gets filled with content dynamically - so we never know how big the content in that div will be.
The beginning of the #absolute div must always be rendered underneath the #fixed div. The #absolute div also gets filled with lengthy content dynamically, so the user must be able to scroll the content in that div, no matter how big it gets.
Without knowing the size of the #fixed div, is there a way using only CSS that we can keep the beginning of the #absolute div underneath the #fixed div?
XHTML:
<div id="right">
<p>This div is just here to force a scrollbar.</p>
</div>
<div id="fixed">
<p>This div gets filled dynamically with content of varying length</p>
</div>
<div id="absolute">
<p>This div also gets filled dynamically with content of varying length,
and needs to stay underneath the div above.</p>
<p>This div will sometimes get so high that it stretches below the bottom of the page,
and because it's inside a fixed positioned div the user won't be able to read all of its content.</p>
</div>
CSS:
#fixed {
position:fixed;
border:2px solid green;
width:200px;
display:block;
background-color:white;
}
#absolute {
position:absolute;
border:2px solid red;
width:200px;
margin-top:90px;
z-index:-1;
}
#right {
position:absolute;
right:0px;
width:200px;
height:4000px;
border:2px solid blue;
}
Without knowing the size of the #fixed
div, is there a way using only CSS
that we can keep the beginning of the #absolute div underneath the #fixed div?
No. CSS cannot help you here.
The absolute/fixed elements are ...
removed from the normal flow entirely
([and have] no impact on later siblings).
and:
the contents of an absolutely
positioned element do not flow around
any other boxes
http://www.w3.org/TR/CSS21/visuren.html#absolute-positioning
I was wondering if this were possible, and if it is the best way to go about this:
example image (since I'm not allowed to post pics yet ^^)
So, not only does each column have to be of equal height, but each column also has its own individual footer.
I saw this SO post — how could I rework this technique to apply to the bottom of the divs and not the bottom of the window?
Edit: each column will have content that will constantly change and be of variable height. I'm thinking I could just figure out the equal height columns first, then just absolute position a footer div within those columns. Does its parent div then have to be position: relative?
Looks like a nested div in each that has the same properties. So each outer div is the same size, and so do the inside div.
.outer
{
height:500px;
float:left;
margin-right:20px;
}
.inner
{
height:30px;
width:100%;
margin-top:-470px;
}
<div class="outer">
<div class="inner">
</div>
</div>
Didn't test this; off the top of my head!
