DIV as filling block in another DIV - html

I have a CSS
.nav {
width: 200px;
line-height: 50px;
float: left;
}
.content {
margin: 0px 0px 0px 230px;
}
.container {
border: 1px solid red;
}
And here is the HTML
<body>
<div class="container">
<div class="nav">Some text
<br>more text
<br>even more text
</div>
<div class="content">
<h1>Home</h1>
<p>Text paragraph</p>
</div>
</div>
</body>
This gives me menu on the left and the content on the right. And a red box around the content on the right, but only the half menu on the left.
But I would like to have the red box also around the complete nav-div Can anyone help?
Thanks
Teddy

Add overflow:auto to your container div's CSS:
.container {
border: 1px solid red;
overflow:auto;
}
jsFiddle example
Floating the child div removes it from the flow of the document and the container essentially collapses as if it didn't exist. Adding the overflow restores the behavior you're after.

I think this is a quick fix if you float your container it should solve the problem your having. See here http://jsfiddle.net/1540sscj/
.container {
border: 1px solid red;
float:left;
width:100%;
}

Floating an element removes it from the normal flow of the page with one side effect being that its parent's dimensions won't expand to fit it.
So, what you need to do is clear the floated item. The best way to do this, without using additional markup or using the overflow property, which may cause other issues, depending on your layout, is to use the :after pseudo class on the parent element, like so:
.nav{
width:200px;
line-height:50px;
float:left;
}
.content{
margin:0px 0px 0px 230px;
}
.container{
border:1px solid red;
}
.container::after{
clear:both;
content:"";
display:block;
height:0;
width:0;
}
<body>
<div class="container">
<div class="nav">Xalsdk fjaskldfj alskdfj asädf<br>asdf<br>asdf</div>
<div class="content">
<h1>Home</h1>
<p>Bla bla.</p>
</div>
</div>
</body>
More information on clear
More information on pseudo elements

Best way imho would be to add a div like:
<div style="clear:both;"></div>
Under your floating elements: FIDDLE
This way you don't need to use oveflow:hidden on your container that may give you problems once you have more stuff in your project.
Also you shoudn't use a margin-left for your content as the previous element is already floating left. The best practise if you want to add some margin between nav and content would be to make your content float left as well and then use margin left (the exact size you want) with respect of the nav and not with the left of the window.
Finally, if you don't want to add the clear:both div to the html you could add somethign like
.content:after {
content:'';
display:block;
clear: both;
}
it's a bit less browser (old ones) compatible but cleaner

You have to add overflow:auto to .container in your css
Check my js fiddle
Also the css that modified.
.container {
border: 1px solid red;
overflow:auto;
}
Description of property overflow from MDN
The overflow property specifies whether to clip content, render
scrollbars or just display content when it overflows its block level
container.

background-color not extending to the entire element

This is my CSS code:
#outer {
width:580px;
padding:10px;
float:left;
}
.inner {
width:560px;
padding: 10px;
background-color:#fff;
color:#666666;
}
And the HTML:
<div id="outer">
<div class="inner">
... a lot of content
</div>
</div>
My problem is the background-color for the inner div doesn't extend to fill the entire div alongside its content. I've had this problem quite often, and my solution has usually been to specify a height for #inner, which makes the background fill #inner accordingly. However, I don't want to specify a height explicitly because it's dynamic content. What should I do to make the background-color fill the div as it extends?
Set the position of each element, with the inner element needing to be absolute, and then just tell the inner div to always fill the outer one with height: 100%. The only care that you have to take with this is that setting the position of inner to absolute will then make it ignore floats, but presumably you are taking care of that with outer.
(I changed the background color to red in this answer to make it more obvious what is going on.)
This is my CSS code:
#outer {
position: relative;
width:960px;
height: 500px;
}
.inner {
position:absolute;
height:100%;
width:400px;
background-color: red;
}
And the HTML:
<div id="outer">
<div class="inner">
... a lot of content
</div>
</div>
I couldn't replicate your issue. If you don't specify a height for '.inner', the background color should extend dynamically as '.inner' fills with content.
You might be having an issue due to a lack of a CSS reset. Each browser has a set of standard css rules it applies to all pages, unless you override these rules.
I recommend adding a CSS reset in your above all your current css.
A very basic but popular reset is by Eric Meyer, found here: http://meyerweb.com/eric/tools/css/reset/
Let me know if that helps, and if not try posting an image of what you are experiencing.
Btw, this is how your code renders for me:
The padding of the outer element will always show the background color of the outer element...
Just remove the padding there.
#outer {
width:580px;
/* padding: 10px;*/
background:red;
border:1px solid green;
}
.inner {
width:560px;
padding: 10px;
background-color:lightblue;
color:#666666;
}

Avoid right-floated DIV wrapping without adding any height in container

I'm trying to have a toolbar always aligned to the right within a DIV without adding any height. The problem I'm finding is making this work both when the box has 100% width and when the width is determined by content. The HTML looks something similar to this:
<div class="box">
<div class="title">
float right
</div>
<div class="toolbar">
<button>1</button>
<button>2</button>
<button>3</button>
<button>4</button>
</div>
</div>
I managed to make it work in Firefox, but Chrome wraps the toolbar when there is not enough space for it instead of increasing the width of the container.
.box {
border: 1px solid #ccc;
display: inline-block;
margin: 5px 0 15px;
}
.title {
display: inline-block;
}
.toolbar {
background: #eee;
float: right;
margin-left: 25px;
}
I would like to find a single set of rules to achieve this regardless the width of the container, but I'm out of ideas unless I use some extra class to differentiate both cases. Also, I'm trying to avoid using overflow or clearfix because I don't want the toolbar to affect the height of the box.
In this fiddle I show all combinations I have tried: http://jsfiddle.net/omegak/c4y4t/2/
You can try this, This worked for me.
.title {
float:left;
}
See if this is the desired output
Updated the below css and added clearfix class to the parent div
.title {
float:left;
}
Add the following CSS and clear the floats on first Div.
.title {
float:left;
}
Here is the demo
I got it working in the end with a little hack.
I gave up on trying the title not to be float: left. Then, to prevent the box to have no height I added overflow: hidden to it. Finally, the hack consists on setting margin-bottom: -999px on the toolbar to prevent it from adding any extra height to the box.
Here is the solution: http://jsfiddle.net/c4y4t/8/

Simple HTML rendering issue

I'm having a doubt in the basics of the HTML rendering. I'm having the following HTML/CSS.
http://jsfiddle.net/cgZ4C/2/
<style type="text/css">
.outer
{
background-color:#DADADA;
width:400px;
border:1px solid silver;
margin:auto;
min-height:50px;
padding:10px;
}
.content
{
float:left;
width:196px;
min-height:20px;
background-color:#BABABA;
margin:2px;
}
</style>
<div class="outer">
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div>
Why is the outer div not growing when the inner content grows? Even I tried adding some text inside .content divs. But still the .outer div is not growing?
You need to add overflow property to your outer div and assign proper value to it like
overflow:hidden
Find what is the most suitable for your need here
Here is the possible code change you need:
.outer
{
background-color:#DADADA;
width:400px;
border:1px solid silver;
margin:auto;
min-height:50px;
padding:10px;
overflow:hidden;
}
CLEAR YOUR FLOATS! Always :-)
Add overflow:auto; like in this code: http://jsfiddle.net/cgZ4C/3/
Many CSS frameworks these days use a class clearfix . That has become the de facto standard. Twitter bootstrap uses it as well. What we need to do is just add a class clearfix to the outer div and you'll be done :)
Although Clearing floats is the correct way to go, sometimes, there is another way you can do this:
float your outer div too!!!
.outer {
float: left;
}
This way, the outer will respect the floated children and expand, but you'll need to float the parent div of outer too, and so on, until there is a ancestor div which is cleared/<body> is encountered.
All floats are like bro's so go along with each other much better than non-floated non-cleared divs.
:)
Add attribute overflow: hidden to the .outer style.
It doesn't grow because all of your content within the parent is floated. When an element is floated, it is no longer taken into consideration by the parent when it calculates it's total size. Since every element is floated, as far as the parent is concerned there is no content, so it doesn't resize.
Your code looks like a table so, with display:table (source) the element will behave like a table element.
http://jsfiddle.net/eWwtp/
.outer
{
background-color:#DADADA;
width:400px;
border:1px solid silver;
margin:auto;
min-height:50px;
padding:10px;
display:table
}
Another solution, that avoid these issues:
But with overflow hidden, more issues can arise where items outside of that div are hidden, or cut off (usually with menus etc).

Add:
<div class="clear"></div>
.clear{clear:both}

Floating div expands to 100% in IE7

I have the following simple layout:
div.main
{
width: 300px;
border: 2px solid #98999E;
overflow: auto;
}
div.main > div
{
float: right;
border: 2px solid #FF3700;
margin: 2px;
}
div.inner > div
{
float: right;
}
<div class="main">
<div class="inner">
<div>123</div>
<div>456</div>
</div>
<div>999</div>
</div>
In Chrome and Firefox, this is rendered as expected - all the content is within the same line:
However, when testing this in IE7 (or actually IE8 in compatibility mode, to be exact), the first div under the main one takes a width of 100%, and therefore the second is pushed beneath it:
An example can be found here.
How can that be fixed?
(Edit:
It turns out that this is happening in IE9 in compatibility mode as well)
(Edit 2: It seems that this is happening with float:right only, and doesn't with float:left)
Apply display: inline; or display: inline-block; to the inner div.
w3.org - 9.2.2 Inline-level elements and inline boxes
IE might need a width...technically you're supposed to have a width assigned when you are floating an element.
Try adding a div with a style of clear:
div.main{
width: 300px;
border: 2px solid #98999E;
overflow: auto;
}
div.main > div {
float: right;
border: 2px solid #FF3700;
margin: 2px;
}
div.inner > div {
float: right;
}
div.clear{
clear:both;
}
<div class="main">
<div class="inner">
<div>123</div>
<div>456</div>
</div>
<div>999</div>
<div class='clear'>
</div>
This MUST be done with a div (or some other block level element). It's always good CSS form to clear your floats at the same level at the same level as you create them, after all the floated elements. Let me know if it works for you. Cheers.
I'd suggest that you specify width for floated <div>. That way, you will be more sure about the layout; rather than relying the rendering completely on the browser. Also, it'd hopefully help you visualize what layout you're trying to get at.
Just from the example above, maybe using floating <span> inside a <p> will accomplish what you need? Or, just right-align a paragraph.

centering a div between one that's floated right and one that's floated left

I have a page in which a header consists of three divs - one that's floated to the left, one that's floated to the right, and one that's in between them. I'd like for that central div to be centered, yet sadly float: center doesn't exist and I can't just float it to the left and add padding as it'd have to change depending on the window size.
Is there something simple I'm overlooking? Or how would I do such a thing?
Update:
In addition, I'd like to find a way of centering that middle div in the space between the divs in case that looks better.
If you have two floated divs, then you know the margins. The problem is that the float:right div should be put before the middle div. So basically you will have:
left-floated | right-floated | centered
Now, about the margins: usually you can just use margin:0 auto, right? The problem is that right now you know the values of the margins: floated divs! So you just need to use:
margin:0 right-floated-width 0 left-floated-width
That should work.
Years later edit
Meanwhile, a new toy is in town: flexbox. The support is fairly good (i.e. if you don't need to support lower than IE 10) and the ease of use is way over floats.
You can see a very good flexbox guide here. The example you need is right here.
Indeed, the important part is that the centered div come after the left and right divs in the markup. Check out this example, it uses margin-left: auto and margin-right: auto on the centered div, which causes it to be centered.
<html>
<head>
<style type="text/css">
#left
{
float: left;
border: solid 1px red;
}
#mid
{
margin-left: auto;
margin-right: auto;
border: solid 1px red;
}
#right
{
float: right;
border: solid 1px red;
}
</style>
</head>
<body>
<div id="left">
left
</div>
<div id="right">
right
</div>
<div id="mid">
mid
</div>
</body>
</html>
Here's a JS Bin to test: http://jsbin.com/agewes/1/edit
Usually you can use flexbox instead of floats:
https://jsfiddle.net/h0zaf4Lp/
HTML:
<div class="container">
<div>left</div>
<div class="center">center</div>
<div>right</div>
</div>
CSS:
.container {
display: flex;
}
.center {
flex-grow: 1;
}
The element with the centered content needs to be specified after both floated elements. After that, simply set the middle element to text-align: center. The text in the centered element will squeeze in between the floats.
See here:
http://jsfiddle.net/calvintennant/wjjeR/
Try this (make sure to use better class names):
.left {
float:left;
width:200px;
}
.right{
float:right;
width:200px;
}
.center {
overflow:hidden;
zoom:1;
}
The center div will fit between the two floats.
If you want to create a gutter between that centered div and the two floats, then use margin on the floats, not on the center div.
Because of "zoom", the CSS will not validate, but that layout will work in IE 5.5 and 6.
Note that source order is important here: the two floats must come first, then your "centered" div.
In some cases, you have a limitation and cannot change the page markup by moving the middle div after the right-floated div. In that case, follow these instructions:
For container: position: relative
For middle div: position: absolute; left: [containerWidth - middle-width / 2]
I hope you got the idea.
A simple solution without having to change the order of the divs (sometimes we can not do this) could be an absolute positioning for the center div as follows:
.container {
position: relative;
}
.container div {
width: 200px;
background: red;
}
.left {
float: left;
}
.right {
float: right;
}
.center {
position: absolute;
top: 0;
left: 0;
right: 0;
margin: auto;
}
<div class="container">
<div class="left">left</div>
<div class="center">center</div>
<div class="right">right</div>
</div>
