Inner Divs overflow Outerdiv

I am dynamically creating multiple divs inside a div. I want all these inner divs to avoid overflowing from the outer div. I have attached jsfiddle to reproduce the problem.
https://jsfiddle.net/t3jgdodm/1/
attaching CSS:
html,
body {
height: 100%;
}
#topDiv {
background-color: lightblue;
max-height: 100px;
width: 100%;
padding: 10px;
}
#insideDiv {
background-color: pink;
max-height: inherit;
overflow-y: auto;
}
I want all divs to be under single scroll.
I am using multiple divs as each div represents a new entered keyword and the div will dynamically generate inside the outer div. I am ready to change the div element into other HTML element if the problem if due to div element.

Is this what your trying to do?
https://jsfiddle.net/t3jgdodm/2/
#topDiv {
background-color: lightblue;
max-height: 100px;
width: 100%;
padding: 10px;
overflow-y: scroll;
}
i added overflow-y: scroll to you #topDiv element id

Important note: You're using repeating ID's which is completely taboo. Make them classes if you plan on re-using them, as I have in my example below.
To have a scrollbar on the outer div, put overflow: auto on your #topDiv instead of your .insideDiv. https://jsfiddle.net/t3jgdodm/11/
#topDiv {
background-color: lightblue;
max-height: 100px;
width: 100%;
padding: 10px;
overflow: auto;
box-sizing: border-box;
}
.insideDiv {
background-color: pink;
}
I've added a box-sizing: border-box; to #outerDiv so that the padding: 10px + width: 100% doesn't cause it to flow off the screen.
Also, I've removed max-height from .innerDiv to avoid having them overlap.

Just remove the max-height: inherit from the #insideDiv (it's inheriting the max-height: 100px from it's parent) and move the overflow-y: auto to the #topDiv.
html,
body {
height: 100%;
}
#topDiv {
background-color: lightblue;
max-height: 100px;
width: 90%;
padding: 10px;
overflow-y: auto;
}
#insideDiv {
background-color: pink;
}
In your exact fiddle, the scrollbar gets pushed off the edge. That's just because the width of the #topDiv exceeds 100% (you need to add box-sizing: content-box to prevent that).
Also, probably just in your example, but remember you shouldn't have more than one element with any given ID. Use a class instead.

The problem was with max height attribute. I changed the css to height.
html,
body {
height: 100%;
}
#topDiv {
background-color: lightblue;
height: 100px;
width: 100%;
padding: 10px;
}
#insideDiv {
background-color: pink;
height: 33%;
overflow: scroll;
}

I wanted to give a proper answer for your issue.
Don't control overflow with the child (#innerDiv), control it with the parent (#topDiv). You don't tell water where to go, you put in a different-sized glass.
Here's an example:
<div id="parent">
<div>
Some inside content
<br> More inside content
<br> More inside content
<br> More inside content
<br> More inside content
<br> More inside content
<br> More inside content
<br> More inside content
<br> More inside content
<br> More inside content
<br>
</div>
</div>
#parent {
background-color: lightblue;
max-height: 100px;
overflow-y: scroll;
}

The problem is you have multiple divs with the same id, make that id a class first of all, secondly you have max-height: inherit on the insidediv, all this means is they get the max-height from the parent, so they'll have the same max-height as the topDiv, with no real restriction. The only real ways I can think of to fix this are to either put an overflow: auto on the outer div or somehow work out what the height of the insidedivs should be.
So to simplify, the HTML should be more like:
<div id="topDiv">
<div class="insideDiv">
Some inside content
<br> More inside content
<br> More inside content
<br>
</div>
<div class="insideDiv">
<br>check
<br>check
</div>
<div class="insideDiv">
<br>check
<br>check
</div>
</div>
and the CSS should be more like:
html,
body {
height: 100%;
}
#topDiv {
background-color: lightblue;
max-height: 100px;
width: 100%;
padding: 10px;
overflow-y: auto;
}
.insideDiv {
background-color: pink;
overflow-y: auto;
}
Or completely remove the overflow-y from the insideDiv class and keep it on just the topDiv id.

remove "max-height: 100px" from topDiv. It will work

Using pure CSS, make a div centered until it runs into sidebar from resizing the window?

I want to create a website with a single fixed-width centered column and an additional fixed-width sidebar that is position: fixed on the left. When the window is large, this works perfectly, but when I resize the window, they begin to overlap when there's plenty of room left on the right side of the window. For example:
I'd like the center div to be positioned in the center until it runs into the sidebar, at which point I'd like it to have a more fluid responsive design, where the sidebar starts to push the div to the right as you resize the window. For example:
The only solution I'm aware of is something like this (using the jQuery resize event and adding a class to the center column when the window resizes small enough):
var SMALL_WINDOW_SIZE = 560;
function checkWindowSize() {
var $content = $("#content");
if ($(this).width() < SMALL_WINDOW_SIZE && !$content.hasClass("smallWindow")) {
$content.addClass("smallWindow");
} else if ($(this).width() >= SMALL_WINDOW_SIZE && $content.hasClass("smallWindow")) {
$content.removeClass("smallWindow");
}
}
$(document).ready(function() {
checkWindowSize();
});
$(window).resize(function() {
checkWindowSize();
});
#sidebar {
background: orange;
width: 100px;
height: 200px;
position: fixed;
top: 10px;
left: 10px;
}
#content {
background: blue;
width: 300px;
height: 350px;
margin: 0px auto;
}
.smallWindow {
float: left;
margin-left: 120px !important;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div id='sidebar'></div>
<div id="content"></div>
I can't help but feel there should be a pure CSS solution or one that uses less or more elegant JavaScript. Is there such a thing?

This isn't by any means the best way of achieving the desired effect with CSS, but it's the methodology behind using CSS media queries to adapt layout that I want to convey.
Obviously if this meets your needs, you'll want to adjust the numbers/widths to suit your case.

How do you make a div only extend in one direction when the outer container size increases?

I'm trying to make a a page container with a navigation bar on the left (inside of the container). When the outer page is wider than the container, I would like just the navigation bar to extend left up to a certain size while the rest of the container's contents to remain the same and stay in the middle of the outer page.
To illustrate my idea, here are the before and after images, with black representing the outer page, blue the page container, pink the leftnav, and green the rest of the container.
Here is also the general structure of the code I am writing. The jsfiddle link includes some css for detail.
<div id="page">
<div id="container">
<div id="leftCol">
LEFT
</div>
<div id="rightCol">
RIGHT
</div>
</div>
https://jsfiddle.net/6L1zrj6e/1/
Currently, my container has a fixed width and automatic margins so as to center it. Is what I am trying to achieve even possible with the current layout? Would I need to move the leftnav div outside of the container?

Here's a pure css solution: fiddle
This is a trick I learned here: here
where you have to put the float first, then make the div respect it by creating a new block formatting context, then the div will expand to the remaining space. Throw in a couple min/max widths to conform it and a wrapper with min/max widths as well and it falls into place. The html background makes the body background not extend past the body as it normally would. Another little trick.
<div class="wrap">
<main></main>
<nav></nav>
</div>
html {
background: white;
}
body {
background: purple;
padding: 0;
margin: 0;
}
.wrap {
margin: 0 auto;
max-width: 1080px;
min-width: 920px;
}
nav {
overflow: auto; /* force a new context to respect float */
background: red;
height: 300px;
min-width: 200px;
max-width: 360px;
}
main {
float: right;
background: green;
height: 300px;
width: 720px;
}

You can try the following: Full screen example
jsFiddle
HTML:
(Took leftCol out of container)
<div id="page">
<div id="leftCol">
LEFT
</div>
<div id="container">
<div id="rightCol">
RIGHT
</div>
</div>
</div>
JS: (Update the width on page resize and on load)
$(window).on('resize', function(){
var containerWidth = 980;
var pageWidth = $(window).width();
var tempW = Math.max(0, pageWidth-containerWidth) / 2;
tempW += 200;
var w = Math.min(tempW, 360); // 360 = max width
var l = Math.max(0, tempW - w);
$('#leftCol').css({'width': w+'px', 'left': l+'px'});
}).resize();
CSS: (Removed floats, using absolute position for leftCol)
#page{
background-color: purple;
position:relative;
}
#container {
background-color: blue;
width: 980px;
height: 300px;
margin: 0 auto;
}
#leftCol {
position:absolute;
top: 0;
left: 0;
background-color: red;
height: 300px;
width: 200px;
}
#rightCol {
padding-left:200px;
background-color: green;
height: 300px;
width: auto;
}

This is what I think you're after - forgive me if I'm wrong!
EDIT: Added outer container wrapper for right margin:
Updated HTML:
<div id="page">
<div id="outercontainer">
<div id="container">
<div id="leftCol">
LEFT
</div>
<div id="rightCol">
RIGHT
</div>
</div>
</div>
</div>
And the CSS:
#page{
background-color: purple;
height: 300px;
}
#outercontainer {
margin: 0 5% 0 0;
}
#container {
background-color: blue;
height: 300px;
margin: 0 auto;
min-width: 300px;
max-width: 600px;
position: relative;
}
#leftCol {
background-color: red;
height: 300px;
margin-right: 200px;
}
#rightCol {
position: absolute;
background-color: green;
width: 200px;
top: 0;
right: 0;
bottom: 0;
}
This gives the #container a min and max width, and the margins will show beyond the max. These are set quite small to show up well in JSFiddle.
leftCol will expand to fit the available space, and it's right-margin prevents it overflowing the rightCol.
rightCol is absolutely positioned (within #container) in the leftCol's margin.
JSFiddle here: https://jsfiddle.net/xuew6og5/1/
The #outerwrapper allows a visible right margin, until the page gets to minimum width at least. If you want the margins to be balanced, change its margin to 0 5%
Update: New JS Fiddle with right margin: https://jsfiddle.net/xuew6og5/2/
Update 3: Sorry, I missed your requirement for a max-width of 360px on the leftCol. Updated the CSS above, and a fiddle here: https://jsfiddle.net/xuew6og5/4/

In order to achieve the wanted effect you need to move the leftCol outside of your container and give your rightCol a margin-left with the size of your leftCol.
Also add a min-width and max-width to your lefCol and a width using calc to adjust it's width to your goals.
Note: lefCol width is calculated like this:
100% / 2 - (Container width / 2 - leftCol min-width)
So your altered html looks like this:
<div id="page">
<div id="leftCol">
LEFT
</div>
<div id="container">
<div id="rightCol">
RIGHT
</div>
</div>
</div>
Your new CSS looks like this:
#page{
background-color: purple;
}
#container {
background-color: blue;
width: 300px;
height: 300px;
margin: 0 auto;
}
#leftCol {
float: left;
background-color: red;
height: 300px;
min-width:100px;
width:calc(100%/2 - 50px);
max-width:200px;
}
#rightCol {
margin-left:100px;
background-color: green;
height: 300px;
width: 200px;
}

How to make a relatively positioned child to get all parent's height

I have this layout
body, html {
height: 90%;
}
#content{
width: 100%;
height: 100%;
}
#sidebar {
position: relative;
width: 200px;
float: left;
height: 100%;
background-color: green;
}
#sidebar-content {
height: 120px;
background-color: blue;
}
#sidebar-footer {
position: absolute;
bottom: 0;
height: 50px;
width: 100%;
background-color: black;
}
#main {
position: relative;
overflow: hidden;
background-color: red;
}
#main-content {
height: 750px;
}
<div id="content">
<div id="sidebar">
<div id="sidebar-content">
</div>
<div id="sidebar-footer">
</div>
</div>
<div id="main">
<div id="main-content">
</div>
</div>
</div>
I need the sidebar to occupy all height available if it's height lower than the #main's. Setting the sidebar position to absolute solves this, but adding even more bugs, is there a solution for the relatively positioned child to get all the parent's height without specifying height of the parent in pixels?
As you can see in the fiddle, if #main exceeding the sidebar's width the sidebar is shorter, but it need to fill all the height.

CSS Flexbox does indeed solve your problem, and is the perfect answer if you don't have to support older browsers.
Basically, just adding display: flex to the container will sort this out for you.
Browsers support flexbox in a variety of ways, make sure you check the compiled CSS of that Pen to get all the browser pre-fixes and such.
Link to CodePen

You may be able to use a combination of css properties to achieve what you are looking for. The main reason you were running into trouble with the position:absolute was due to your float:left.
Have a glance through this and you may find some of the positioning and width declarations useful in your implementation:
body,
html {
height: 90%;
}
#content {
width: 100%;
height: 100%;
position: relative;
background: lightgray;
}
#sidebar {
position: absolute;
width: 200px;
height: 100%;
top: 0;
left: 0;
background-color: green;
z-index: 8;
}
#sidebar-content {
height: 120px;
background-color: blue;
}
#sidebar-footer {
position: absolute;
bottom: 0;
height: 50px;
width: 100%;
background-color: black;
}
#main {
overflow: hidden;
background-color: red;
height: 100%;
position: absolute;
top: 0;
left: 200px;
width: calc(100% - 200px);
height: 100%;
z-index: 10;
}
#main-content {}
<div id="content">
<div id="sidebar">
<div id="sidebar-content">
</div>
<div id="sidebar-footer">
</div>
</div>
<div id="main">
<div id="main-content">this is the main content
</div>
</div>
</div>

I guess jQuery solution will help you solve your problem :) Try this This will allow to have the #sidebar to have same height as the container. Hope this helps :) Happy coding.
jQuery:
$(document).ready(function(){
var wrapH = $('#content').outerHeight();
$('#sidebar').css("height", wrapH);
});
Edited:
JS Fiddle Link
$(document).ready(function(){
var wrapH = $('#main').outerHeight();
$('#sidebar').css("height", wrapH);
});
Just change the content to main. Hope this solves the issue. This will make the sidebar height be the same as the main height.

Emulating a fixed sidebar template issues

am trying to emulate this theme:
http://themetrust.com/demos/ink/?project=the-city-of-samba
But instead make the blog post always remain centered in the right hand side (space outside of the fixed sidebar) and have the blog post be of a % width.
I currently have this set up on my site, but am using a percentage based sidebar which looks awful.
Here is a JSfiddle recreating in basic terms the theme from above:
http://jsfiddle.net/Uyv6w/4/
All i am after is to make that grey inner div always remain centered inside the red content div.
Incase JSFiddle goes down and for future ref:
HTML:
<div id="container">
<div id="sidebar"></div>
<div id="content">
<div id="inner"></div>
</div
</div>
CSS:
* {
margin: 0; padding: 0;
}
html, body {
width: 100%;
height: 100%;
background-color: #333;
}
#container {
height: 100%;

#sidebar {

}
Thanks.

There are just 2 properties to change in ordre to make this work the way you want :
#content {
/* width: 100%; */
margin-left: 100px; /* the width of you sidebar.
Since #content is a div, a block-level element
, its width will be automatically 100%
, minus the margins */
background-color: #f00;
}
#inner {
width: 60%;
/* margin-left: 150px; */
margin-left: auto;
margin-right: auto; /* having margin-left & right set to auto will center your div.
you could also use "margin: 0 auto" */
background-color: #888;
height: 1000px;
}
I have updated you JSFiddle example here : http://jsfiddle.net/Uyv6w/5/

http://jsbin.com/requv/1/edit
if you set body, html (and the container) to height 100%, it will not be able to to scroll.
the height should be more then 100%.
