dynamic and fixed size in CSS - html

I need in the same HTML row to have 2 divs: one will stay the same width while the other's size will be increased once the web page is being increased by the end user.
So I defined one div and inside 2 divs like this:
<div>
<div style="float:left" width="20px">first div</div>
<div style="float:left" width="100%">first div</div>
</div>
However it does not work!
How can I create 2 divs in the same line that one will be fixed size and the other one relative?

Do I win?
Live Demo
Live Demo #2 (using classes and with support for more than one instance of this)
HTML:
<div id="divHolder">
<div id="div1">1</div>
<div id="div2">2</div>
</div>
CSS:
#divHolder {
overflow: auto
}
#div1 {
float: left;
width: 20px;
background: #ccc
}
#div2 {
margin-left: 20px;
background: #888
}

Take a look at this: http://jsfiddle.net/Shaz/GaZYt/2/
The left box will change size depending how much horizontal space is left. The right box will always have a minimum and maximum width of 200px.

Try setting display:inline on the div elements. The default display value for a div is block (which causes them to appear on seperate lines). Here is an example on js fiddle

I believe you may need to use Javascript to handle this case.
$(window).resize(function() {
var $left = $('#left');
var $container = $('#container');
$right.width($container - $left);
});

How to create two <div>s with one taking up maximum width

I have a table that needs to be transformed into CSS-based layout, because of responsive-design requirements:
<table>
<tr><td>minimal width</td><td width="100%">maximum width</td></tr>
</table>
Is it possible to create two div s that replace the two td s in the above example?
Unfortunately, the answers to this question is not appropriate, because the first answer uses a fixed width for the left column and the in the second answer any 100% width-element on the right side causes the right div to slide under the left one. I need the same behavior as the table: Use the maximum available width, keep on the right side and use horizontal scrolling if not enough space is available.
Is it possible to do?
Sure, like this:
div {
display:table-cell;
border:1px solid #999;
}
#b {
width:100%;
}
<div id="a">
a
</div>
<div id="b">
b
</div>
Try this code in your window for your own results. When I run this in snippets, it functions correctly.
The div id=one has a fixed 100px width. The max-width for div id=two is decided in the jQuery in which it gets the width of the window you currently are using, and it subtracts the amount of the fixed width of the div id=one.
The div that encompasses them all has a flex display to erase the blank space that generally shows up between divs, which adds pixels and would make the 100% - 100px width still appear on the line below because it would be too big.
$("#two").css("max-width", ($(window).width() - 100) + "px");
#one {
display:inline-block;
width: 100px;
border: 2px solid black;
}
#two {
display:inline-block;
border: 2px solid red;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div style="display:flex">
<div id="one">stuff</div><div id="two">more stuff more stuff more stuff more stuff more stuff more stuff more stuff more stuff more stuff more stuff more stuff more stuff</div>
</div>

Make one <div>'s height match another's

I want to create a header with 2 divs in it. The left div needs to be the same height as the right one, but the right one can scale based on its contents.
The left div's contents need to be vertically aligned to the middle.
I tried something like this:
<header>
<div id="test1">
<div>LOGO</div>
</div>
<div id="test2">
<h1>texttexttexttexttexttexttexttexttexttexttexttexttexttexttexttext</h1>
</div>
</header>
Use display: table-cell;
Working Demo
Edit:
In case if you want jQuery Solution it works on all browsers
You can fake this using overflow, padding and margins. It's completely cross browser compatible and doesn't need any JavaScript or anything. Just CSS. For example:
.header {
overflow: hidden;
}
.test {
background: red;
padding-bottom: 2000px;
margin-bottom: -2000px;
float: left;
width: 100px;
margin-right: 20px;
}​
DEMO
There is also always faux cols (using a background image) but this is a better method that doesn't need images.
If you don't mind a bit of javascript:
$(document).ready(function() {
setHeight($('#test1'), $('#test2'));
// When the window is resized the height might
// change depending on content. So to be safe
// we rerun the function
$(window).on(resize, function() {
setHeight($('#test1'), $('#test2'));
});
});
// sets height of element 1 to equal the height of element 2
function setHeight(elem1, elem2) {
var height = elem2.height()
elem1.css('height', height);
}

display: flex;
in the parent container works for me

Dynamically adjusting two outside columns to the variable width of the center column

I would consider myself to be an intermediate/advanced CSS/HTML coder but I'm stumped on how to do the following scenario.. I'm starting to think it is impossible but I really want to believe it is..
Let's say the wrapper width is 1000px.
Within it is three columns. The two outside columns are the same width, this width is decided by the center column. The center column is the only one with content, just one line of text with 30px of padding on either side. So if the line of content is 100px with padding, than the other two columns would be (1000-100)/2 each..
Is there a dynamic way to have the two outside columns adjust to the varying width of the center column that is defined by its varying contents, one line of text?
Graphic of what I am trying to accomplish:
The very closest I could come up with was to use display: table; and table-cell. This creates the dynamic effect you're looking for, but I don't think you can get your desired effect without setting an explicit width to the center element.
HTML:
<div id="wrap">
<div id="left">
Left
</div>
<div id="center">
center
</div>
<div id="right">
Right
</div>
</div>
CSS:
#wrap
{
width: 1000px;
display: table;
}
#wrap div
{
display: table-cell;
border: 1px solid #000;
width: auto;
}
#center
{
padding: 0 30px;
text-align: center;
}
You can check out my attempt here, it has some buttons for you to see the different states, width on/off and add text etc. (the jQuery has nothing to do with the solution)
I think this is as close as you're going to get with pure CSS.
Good 'ole tables to the rescue:
http://jsfiddle.net/hgwdT/
Actually I think tables are the devil, but this works as you described. And so here it is using display: table-cell on the child divs, so it is functionally the same using nicer markup:
http://jsfiddle.net/XXXdB/
The center element can indeed have a dynamic width; to prevent the content from being squished, I simply added a white-space: nowrap to the p containing the text.
I also confirmed that this solution works in IE8 and FF, in addition to Chrome.
This not the most elegant solution, but it works. I wanted to go the pure CSS route, but couldn't figure it out. Nice work, jblasco and Kyle Sevenoaks, on figuring that out!
Here is my jsFiddle demo. If you don't mind using a little JavaScript though (utilizing jQuery in my example):
HTML:
<div id="wrapper">
<div class="side"></div>
<div id="middle">One line of text.</div>
<div class="side"></div>
</div>
CSS:
#wrapper {
margin: 0 auto;
width: 1000px;
}
#wrapper div {
float: left;
height: 300px;
}
.side {
background: #ddd;
}
#middle {
background: #eee;
padding: 0 30px;
text-align: center;
}
JavaScript:
var adjustSize = function(){
// Declare vars
var wrapper = $('#wrapper'),
middle = $('#middle'),
totalWidth = wrapper.width(),
middleWidth = middle.width(),
middleOuterWidth = middle.outerWidth(),
remainingWidth = totalWidth - middleOuterWidth,
sideWidth;
if(remainingWidth % 2 === 0){
// Remaining width is even, divide by two
sideWidth = remainingWidth/2;
} else {
// Remaining width is odd, add 1 to middle to prevent a half pixel
middle.width(middleWidth+1);
sideWidth = (remainingWidth-1)/2;
}
// Adjust the side width
$('.side').width(sideWidth);
}

Fit divs into fixed space

This is what I am trying to do :
HTML
<div class="container">
<div id="one" class="child">One</div>
<div id="two" class="child">Two</div>
<div id="three" class="child">Three</div>
<div id="four" class="child">Four</div>
</div>
CSS
<style type="text/css">
.container{
height:40px;
width:500px;
}
.class{
float:left;
/*...*/
}
</style>
The child divs should fill the container div how big or small it has its width. They can get big according to the container automatically.
|<---One----><---Two---><-Three-><--Four-->|
How can I do it with css?
Thanks in advance.
I've set up a test site to make sure this works:
First, you'll need to keep float to "left" to keep everything on the same row. Next, set width to "25%", to space out the elements. Finally, set text-align to "center" to center the elements, as in your diagram. Remember, if you change the number of elements, you'll need to modify the "25%" to a value that evenly spaces out the elements. (Use 100 / numElements).
.child {
float: left;
width: 25%;
text-align: center;
}
Does anyone know a way to do this without using width percentages, so that it will auto-spread the elements if they are removed or added?
You can set the .child width to 25%, like this:
.child { width 25%; }
You can test it out/play with it here.
Total width is 500 so each child div should be 125px wide. You got the right idea using the float:left;
The solutions that have been given to you are correct. Just be careful if you have margins/borders/paddings in the inner divs, because in that case the 25% would break the layout (margin, borders and paddings are not included in the percentage).

Setting a div's height in HTML with CSS

I am trying to lay out a table-like page with two columns. I want the rightmost column to dock to the right of the page, and this column should have a distinct background color. The content in the right side is almost always going to be smaller than that on the left. I would like the div on the right to always be tall enough to reach the separator for the row below it. How can I make my background color fill that space?
.rightfloat {
color: red;
background-color: #BBBBBB;
float: right;
width: 200px;
}
.left {
font-size: 20pt;
}
.separator {
clear: both;
width: 100%;
border-top: 1px solid black;
}
<div class="separator">
<div class="rightfloat">
Some really short content.
</div>
<div class="left">
Some really really really really really really
really really really really big content
</div>
</div>
<div class="separator">
<div class="rightfloat">
Some more short content.
</div>
<div class="left">
Some really really really really really really
really really really really big content
</div>
</div>
Edit: I agree that this example is very table-like and an actual table would be a fine choice. But my "real" page will eventually be less table-like, and I'd just like to first master this task!
Also, for some reason, when I create/edit my posts in IE7, the code shows up correctly in the preview view, but when I actually post the message, the formatting gets removed. Editing my post in Firefox 2 seems to have worked, FWIW.
Another edit: Yeah, I unaccepted GateKiller's answer. It does indeed work nicely on my simple page, but not in my actual heavier page. I'll investigate some of the links y'all have pointed me to.
Ahem...
The short answer to your question is that you must set the height of 100% to the body and html tag, then set the height to 100% on each div element you want to make 100% the height of the page.
Actually, 100% height will not work in most design situations - this may be short but it is not a good answer. Google "any column longest" layouts. The best way is to put the left and right cols inside a wrapper div, float the left and right cols and then float the wrapper - this makes it stretch to the height of the inner containers - then set background image on the outer wrapper. But watch for any horizontal margins on the floated elements in case you get the IE "double margin float bug".
Give this a try:
html, body,
#left, #right {
height: 100%
}
#left {
float: left;
width: 25%;
}
#right {
width: 75%;
}
<html>
<body>
<div id="left">
Content
</div>
<div id="right">
Content
</div>
</body>
</html>
Some browsers support CSS tables, so you could create this kind of layout using the various CSS display: table-* values. There's more information on CSS tables in this article (and the book of the same name) by Rachel Andrew: Everything You Know About CSS is Wrong
If you need a consistent layout in older browsers that don't support CSS tables, you need to do two things:
Make your "table row" element clear its internal floated elements.
The simplest way of doing this is to set overflow: hidden which takes care of most browsers, and zoom: 1 to trigger the hasLayout property in older versions of IE.
There are many other ways of clearing floats, if this approach causes undesirable side effects you should check the question which method of 'clearfix' is best and the article on having layout for other methods.
Balance the height of the two "table cell" elements.
There are two ways you could approach this. Either you can create the appearance of equal heights by setting a background image on the "table row" element (the faux columns technique) or you can make the heights of the columns match by giving each a large padding and equally large negative margin.
Faux columns is the simpler approach and works very well when the width of one or both columns is fixed. The other technique copes better with variable width columns (based on percentage or em units) but can cause problems in some browsers if you link directly to content within your columns (e.g. if a column contained <div id="foo"></div> and you linked to #foo)
Here's an example using the padding/margin technique to balance the height of the columns.
html, body {
height: 100%;
}
.row {
zoom: 1; /* Clear internal floats in IE */
overflow: hidden; /* Clear internal floats */
}
.right-column,
.left-column {
padding-bottom: 1000em; /* Balance the heights of the columns */
margin-bottom: -1000em; /* */
}
.right-column {
width: 20%;
float: right;
}
.left-column {
width: 79%;
float: left;
}
<div class="row">
<div class="right-column">Right column content</div>
<div class="left-column">Left column content</div>
</div>
<div class="row">
<div class="right-column">Right column content</div>
<div class="left-column">Left column content</div>
</div>
This Barcamp demo by Natalie Downe may also be useful when figuring out how to add additional columns and nice spacing and padding: Equal Height Columns and other tricks (it's also where I first learnt about the margin/padding trick to balance column heights)
I gave up on strictly CSS and used a little jquery:
var leftcol = $("#leftcolumn");
var rightcol = $("#rightcolumn");
var leftcol_height = leftcol.height();
var rightcol_height = rightcol.height();
if (leftcol_height > rightcol_height)
rightcol.height(leftcol_height);
else
leftcol.height(rightcol_height);
Here's an example of equal-height columns - Equal Height Columns - revisited
You can also check out the idea of "Faux Columns" as well - Faux Columns
Don't go the table route. If it's not tabular data, don't treat it as such. It's bad for accessibility and flexibility.
I had the same problem on my site (shameless plug).
I had the nav section "float: right" and the main body of the page has a background image about 250px across aligned to the right and "repeat-y". I then added something with "clear: both" to it. Here is the W3Schools and the CSS clear property.
I placed the clear at the bottom of the "page" classed div. My page source looks something like this.
body
-> header (big blue banner)
-> headerNav (green bar at the top)
-> breadcrumbs (invisible at the moment)
-> page
-> navigation (floats to the right)
-> content (main content)
-> clear (the quote at the bottom)
-> footerNav (the green bar at the bottom)
-> clear (empty but still does something)
-> footer (blue thing at the bottom)
I hope that helps :)
No need to write own css, there is an library called "Bootstrap css" by calling that in your HTML head section, we can achieve many stylings,Here is an example:
If you want to provide two column in a row, you can simply do the following:
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
<div class="row">
<div class="col-md-6">Content</div>
<div class="col-md-6">Content</div>
</div>
Here md stands for medium device,,you can use col-sm-6 for smaller devices and col-xs-6 for extra small devices
The short answer to your question is that you must set the height of 100% to the body and html tag, then set the height to 100% on each div element you want to make 100% the height of the page.
A 2 column layout is a little bit tough to get working in CSS (at least until CSS3 is practical.)
Floating left and right will work to a point, but it won't allow you to extend the background. To make backgrounds stay solid, you'll have to implement a technique known as "faux columns," which basically means your columns themselves won't have a background image. Your 2 columns will be contained inside of a parent tag. This parent tag is given a background image that contains the 2 column colors you want. Make this background only as big as you need it to (if it is a solid color, only make it 1 pixel high) and have it repeat-y. AListApart has a great walkthrough on what is needed to make it work.
http://www.alistapart.com/articles/fauxcolumns/
I can think of 2 options
Use javascript to resize the smaller column on page load.
Fake the equal heights by setting the background-color for the column on the container <div/> instead (<div class="separator"/>) with repeat-y
Just trying to help out here so the code is more readable.
Remember that you can insert code snippets by clicking on the button at the top with "101010". Just enter your code then highlight it and click the button.
Here is an example:
<html>
<body>
<style type="text/css">
.rightfloat {
color: red;
background-color: #BBBBBB;
float: right;
width: 200px;
}
.left {
font-size: 20pt;
}
.separator {
clear: both;
width: 100%;
border-top: 1px solid black;
}
</style>
This should work for you: Set the height to 100% in your css for the html and body elements. You can then adjust the height to your needs in the div.
html {
height: 100%;
}
body {
height: 100%;
}
div {
height: 100%; /* Set Div Height */
}
It's enough to just use the css property width to do so.
Here is an example:
<style type="text/css">;
td {
width:25%;
height:100%;
float:left;
}
</style>
.rightfloat {
color: red;
background-color: #BBBBBB;
float: right;
width: 200px;
}
.left {
font-size: 20pt;
}
.separator {
clear: both;
width: 100%;
border-top: 1px solid black;
}
<div class="separator">
<div class="rightfloat">
Some really short content.
</div>
<div class="left">
Some really really really really really really
really really really really big content
</div>
</div>
<div class="separator">
<div class="rightfloat">
Some more short content.
</div>
<div class="left">
Some really really really really really really
really really really really big content
</div>
</div>
