CSS Positioning - Two Column Div Layout with Two fixed top DIVs - css

I am attempting to put together a webpage layout with the following elements:
1. A two column setup with menu on the left and main content on the right.
2. A "function bar" fixed to the top of the right column. Fixed and always visible.
Here are the catches:
I want the two columns to scroll independently of each other if their height pushes past the browser window resolution
The Content Managment System I use adds a fixed pane to the top of the page to show control options
I have crafted an image that gives a visual representation of the layout I am after. I hope it helps this make sense.
Image of layout for reference
Here's where I'm at currently in attempting to create this layout
<div class="CMS-Admin-Bar"></div>
<div class="total-wrapper">
<div class="left-pane">
<div class="menu-pane"></div>
</div>
<div class="right-pane">
<div class="Function-Pane"></div>
<div class="Content-Pane"></div>
</div>
</div>
.CMS-Admin-Bar{
position:fixed;
height:43px;
left:0;
top:0;
width:100%;
z-index:10;
}
.total-wrapper{
position:relative;
}
.left-pane{
position:absolute;
top:0;
bottom:0;
left:0;
height:100%;
width:283px;
z-index:8;
}
.right-pane{
position:fixed;
top:0;
left:283px;
right:0;
bottom:0;
overflow:auto;
}
.Function-Pane{
position:fixed;
z-index:8;
top:0px;
left:283px;
height:43px;
}
With this CSS I have a few problems:
The "CMS-Admin-Bar" covers my "Function-Pane" when an admin is logged in.
The "Function-Pane"'s right 283px is being cut off. I need this fixed div to fit in the screen, while still having a fluid width.
I hope I was descriptive enough. Thanks for your help and time!

Check out this: http://codepen.io/anon/pen/kEhny UPDATED AGAIN
The "CMS-Admin-Bar" covers my "Function-Pane" when an admin is logged in.
You will need to find the height of the CMS-Admin-Bar and add padding to the parent element (might be the body for this case) or add a top margin to the total-wrapper element.

It seems like it works in the pen now. Note that this layout really isn't responsive though.

Trouble positioning divs inside other divs

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.

horizontal menu using % positioning

I am making a menu that is a div with with:100%; and height:45px;
each element inside the menu are divs. My goal is to make it adapt to any screen resolution so I start by placing the first div with a margin-left:2%;but the for the next one I am not sure of what I must use.
I could make the first element in float:left; and use margin like margin-left:10%; but then if we change the screen resolution it's not good anymore. If I don't put anything it goes under the first button. If I use the margin-left in px it won't be good because of the first margin-left:2%; How can I achieve this?
This is what I curently have(you can see that the buttons get under the first one):
Why don't you use display:inline-block; and whatever the margins that are great for you?
Meaning that, the first element can have 2% and the second one as well:
<div id="menu">
<div class="element">1</div>
<div class="element">2</div>
</div>
​
#menu{
width:100%;
height:45px;
background:#f00;
}
.element{
background:#0f0;
display:inline-block;
margin-left:2%;
}
​
I think you should provide something like a jsfiddle source when asking these type of questions :)

100% width div for browser width

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)...

How to add a fixed width div next to an auto width div?

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;
}

boxes adding up to 100% of the browser

I want to have 2 boxes right next to each other, one with a fixed width, and another with a width that will change based on the size of the browser. The box has overflow:auto, and I'm trying to get the first box to act as a side bar that will follow you down the page. But of course I can't seem to achieve this, and have come here hoping someone could give me some examples, or point me in the right direction.
Thanks!
To achieve the layout you asked try something along these lines:
HTML:
<div>
<div id="col1">Left Navigation Menu</div>
<div id="col2">Right Content</div>
</div>
CSS:
#col1
{
position:fixed;
width:400px;
}
#col2
{
position:absolute;
left:400px;
}
Will I was trying to think of a good way to do this in CSS, I was channeling my google-fu and found...
http://plugins.jquery.com/project/jStickyScroll
"This plug-in allows you to keep a div element at the top of the browser window when scrolling down a page. The most common use is to keep a sidebar navigation menu from disappearing when scrolling to the bottom of a web page."
You could maybe try...
#element{
position:fixed;
}
Although this doesn't work without hacks in IE6, see
http://www.howtocreate.co.uk/fixedPosition.html
Give this a go (I hope this is what you are after?):
See a live demo here: http://jsfiddle.net/VcecU/
HTML
<div class="main_container">
<div class="content_a">1</div>
<div class="content_lotsoftext">Start. Lots of text goes here! Finish. </div>
</div>
CSS
.main_container{
background-color:#ccc;
overflow:auto;
zoom:1;
}
.content_a{
width:60px;
float:left;
background-color:#3FF;
}
.content_lotsoftext{
float:left;
background-color:#FCF;
margin:-20px 0 0 60px; /* -- Need conditional for IE6 and 7 to remove the margin to get it to work in those browsers --*/
/*-- The following classes help it to sit better in IE6 and 7 --*/
clear:left;
display:inline;
}
Please note, you will need a IE6&7 conditional to remove the margin, clear and display classes from .content_lotsoftext
