I have a div which contains 2 divs, one has fixed height.
I want to make sure that the 2nd div's height is exactly as much as the height of the container div minus the other div's height. This height can't be manually set because it's often resized.
<div id="container" style="height: 50%">
<div id="header" style="height: 30px;">
</div>
<div id="content">
</div>
</div>
i have tried with jquery on resize but i think i wrote something wrong:
$(document).on("resize", "#container", function (event) {
$('#content').height($('#container').height()-$('#header').height());
});
Is there any way (Javascript, CSS) to achieve this?
An alternative to the jQuery method is CSS Flexbox:
#container {
display: flex;
flex-direction: column;
}
#content {
flex: 1;
}
See the demo. Unfortunately, this will only work in browsers supporting the latest Flexbox syntax. (http://caniuse.com/#search=flexbox) Backward compatible code is possible using old syntaxes as well, but will be sightly more involved. See David Storey's article at http://coding.smashingmagazine.com/2013/05/22/centering-elements-with-flexbox/ for more on how to do that.
Your main problem seems to be that you have to size the element initially and then keep listening to the resize event:
function handleResize() {
$('#content').height($('#container').innerHeight()-$('#header').height());
}
$(window).on("resize", handleResize);
handleResize();
Also, the resize event should be attached directly to the window.
Otherwise, I recommend the use of innerHeight() for the container as that takes into account padding.
Also I made some fixes to your CSS for this to fully work:
#container {
position: absolute;
width: 100%;
height: 50%;
}

I have a pure CSS solution for you,
Check out that Working Fiddle
HTML:
<div id="container">
<div id="header"></div>
<div id="content"></div>
</div>
CSS:
#container {
height: 300px; /*Whatever fixed height you want*/
}
#container:before {
content:'';
float: left;
height: 100%;
}
#header {
height: 30px;/*Whatever fixed height you want, or not fixed at all*/
background-color: red;
}
#content {
background-color: blue;
/*No height spesified*/
}
#content:after {
content:'';
clear: both;
display: block;
}

I have a simple 3 column layout with a left sidebar, content area, and right sidebar. I am using flexbox to handle widths. I would like to make it so that when a user drags the right border of the left sidebar, the div can be resized. I would prefer a css solution if it makes sense but am open to javascript or jquery. Whichever approach is easiest for me to understand : )
Here is a possible solution using the css resize property (click Run code snippet to see the result).
Notes:
The resize handler is in the bottom right corner of the left sidebar
The resize property is not yet fully supported by all browser (~74% see caniuse)
The styles for the resize handler are still limited (see this question)
.container {
height: 500px;
display: flex;
}
.left-sidebar {
display: flex;
flex-direction: row;
background-color: #364F6B;
color: #fff;
/* This is for resizing */
overflow: scroll;
resize: horizontal;
}
.center-aria {
background-color: #3FC1C9;
flex-grow: 2;
}
.right-sidebar {
background-color: #FC5185;
}
.left-sidebar, .right-sidebar, .center-aria {
padding: 8px;
}
<div class="container">
<div class="left-sidebar">
Left Sidebar - Resize me
</div>
<div class="center-aria">Center Aria</div>
<div class="right-sidebar">Right Sidebar</div>
</div>
I have three div's.
the first two are fixes width,but there width should not be set to permanent size because it could change. (base of the length of text that is there)
then next to those two I have a fluid div that will change his width dynamically when the user change his window size.
how can I set this kind of structure to work? even with the use of javascript
thanks.
I don't think you can have fixed width divs that resize dynamically unless you use javascript. Have you played around with min-width and max-width css attributes?
Have a look at this demo:
for a markup like this:
<div id="contentwrapper">
<div id="contentcolumn">
...
</div>
</div>
<div id="leftcolumn">
...
</div>
<div id="rightcolumn">
...
</div>
CSS
#contentwrapper {
float: right;
width: 100%;
margin-left: -430px;
}
#contentcolumn {
margin-left: 430px;
}
#leftcolumn {
float: left;
width: 230px;
background: #C8FC98;
}
#rightcolumn {
float: left;
width: 200px;
background: #FDE95E;
}
An example: http://jsfiddle.net/sw9422oy/
IF you don't want to set a fixed width then you should use a fluid-fluid-fluid approach like this one: http://www.dynamicdrive.com/style/layouts/item/css-liquid-layout-33-fluid-fluid-fluid/
I want to have a long page, with a fixed top 100px div, and a fixed 50px bottom div. However, I want the bottom div to scroll as you scroll down the page.
Its hard to explain, but the best example of this is on the front page of PayPal.com
On the first page load, the bottom div looks like it is fixed, and as you adjust the height of the browser window, that div stays at the bottom. Yet as you scroll down the page it is not fixed.
Can anyone explain how they have done this? I am trying to re-create something similar, but cant see how they have managed it.
As far as I can see they have this html...
<div id="fixed-top">
<header class="table-row">
// header content
</header>
<div class="table-row table-row-two">
// Video content
</div>
<div class="table-row">
//bottom content
</div>
</div>
And this CSS...
#fixed-top {
height: 100%;
width: 100%;
display: table;
position: relative;
top: 0;
left: 0;
z-index: 1;
}
.table-row {
display: table-row;
}
But that alone doesn't do it. I also can't see any js thats getting window height and applying it to the main fixed div.
Help! :)
EDIT:
Have just found a way to do it with javascript, controlling the height of the middle row using the window height, minus the 150px for the header and third row.
jQuery(document).ready(function(){
$('div.table-row-two').css({'height':(($(window).height())-150)+'px'});
$(window).resize(function(){
$('div.table-row-two').css({'height':(($(window).height())-150)+'px'});
});
});
But saying that, Zwords CSS only method seems like a winner.
From what I understand, you are looking for something like a sticky footer. So basically if the content is not enough, the footer should go sit at the bottom like its fixed, but if content comes in, it should scroll down like other content.
Try this - http://css-tricks.com/snippets/css/sticky-footer/
First off, you'll need to set the height of the body and html tag, otherwise the table won't take the full screen. Then I altered your code, made it a bit easier.
HTML:
<div id="fixed-top">
<header>
// header content
</header>
<div>
// Video content
</div>
<div>
//bottom content
</div>
</div>
CSS:
html, body {
margin: 0;
padding: 0;
height: 100%;
min-height: 100%;
}
#fixed-top {
display: table;
width: 100%;
height: 100%;
}
#fixed-top > * { /* makes all the direct children of #fixed-top a table row*/
display: table-row;
background: lightblue;
}
#fixed-top > *:nth-child(1) {
background: lightgreen;
height: 40px;
}
#fixed-top > *:nth-child(3) {
background: lightgreen;
height: 25%;
}
You can either set the height to a fix height (in px) or percentages. If you only give two of the three rows a height, the third one will automaticly fill up the rest space.
Also, check this demo.

}

min-height:15px;
}
.wrapper .row:nth-of-type(2){
height:100%;
background-color:white;
}
.wrapper .row:nth-of-type(3){
min-height:15px
}
You can do this easily with jQuery using $(window).height() and subtracting your footer/header's heights. See Fiddle for an example.
Ok, so i want to have a series of divs which are the exact width and height of the user's browser window, regardless of the screen size. I can easily make the divs stretch horizontally with "width: 100%;" but i cant work out how to make the height stretch itself. I am guessing that i need to use some bit of javascript to judge the height, and then another piece to resize the seperate divs. Unfortunately I am a complete javascript n00b and after two hours of seemingly fruitless searching and coming up with about 100 "solutions" this was as far as id gotten (Im sure that at some point I have probably been closer to the answer):
var viewportHeight = "height:" + document.documentElement.clientHeight;
getElementById('section-1').setAttribute('style', viewportHeight);
<div class="section" id="section-1"></div>
<div class="section" id="section-2"></div>
<div class="section" id="section-3"></div>
edit:
ah i should be more clear, im attempting to have all three divs take up the entire screen, so you have to scroll down to see each one - almost like seperate slides. The idea is that each one takes up the entire screen so you cant see the next section until you scroll down, rather than having three divs which take up a third of the screen.
If you haven't already tried it, you'll want to look at parent:child inheritance of elements within the DOM by way of using CSS.
What I want to STRESS is that everyone giving you JS hacks to accomplish this is not only providing you with overkill (YOU did ask for a JavaScript solution, so they gave it to you!), but it's also a deviation from standards. HTML is for structure, CSS is for presentation, and JavaScript is for behavioral aspects... setting a div to the width of the viewport on load is a PRESENTATION aspect and should be done in CSS... not JavaScript. If you were trying to change the width based on events or user interaction, then yes JavaScript is your friend... but stick with just HTML and CSS for now.
The trick is that most elements have an undefined height - and height is later defined by the content that the element holds.
If you want to 'trick' an element into having a height other than what it wants to default to, you'll have to explicitly define it. Since you want to inherit your height from the viewport, you'll have to define the height at the top and bring it down...
You might be in luck and can avoid JavaScript altogether (unnecessary). Just use CSS.
Try something like:
html, body {
height: 100%;
width: 100%;
}
Now, when you try to set your div's later on, specify width: 100% and the height gets inherited from the html --> body --> div.
Try that and see if that solves your problem - if not, point us to a website, a pastebin, or a SOMETHING with code in it that we can just show you how to do it (whereas what you posted for code was an attempt in JavaScript which is only 1 part of the code - post the full thing either to a server or temp site like pastebin).
Here is some sample code I wrote (tested in Chromium):
The HTML:
<html>
<head>
<title>Test Divs at 100%</title>
<link rel="stylesheet" type="text/css" href="divtest.css"
</head>
<body>
<div class="test1">aef</div>
<div class="test2">aef</div>
<div class="test3">aef</div>
</body>
</html>
The CSS:
html, body {
width: 100%;
height: 100%;
background-color: #793434;
padding: 0;
margin: 0;
}
div {
height: 100%;
width: 100%;
}
.test1 {
background-color: #E3C42E;
}
.test2 {
background-color: #B42626;
}
.test3 {
background-color: #19D443
}
try this
div#welcome {
height: 100vh;
background: black;
color: white;
}
div#projects {
height: 100vh;
background: yellow;
}
<div id="welcome">
your content on screen 1
</div>
<div id="projects">
your content on screen 2
</div>
it should work for you, but little support in IE
A bit of jQuery should do it:
$(document).ready(function() {
var window_height = $(window).height();
$('#section-1").height(window_height);
});
And if you want to keep 100% height on window resize:
$(document).ready(function() {
function viewport_height() {
var window_height = $(window).height();
$('#section-1").height(window_height);
}
viewport_height();
$(window).resize(function() {
viewport_height();
});
});
try this
window.onload = init;
function init()
{
var viewportHeight = "height:" + document.documentElement.clientHeight+"px;";
document.getElementById('section-1').setAttribute('style', viewportHeight);
}
Here is a script free solution, just CSS. This assumes that the divs are directly in the body element or a parent with position absolute and the parent has no padding.
#section-1 {
position: absolute;
height: 100%;
width: 100%;
background: #ff0000;
}
#section-2 {
position: absolute;
width: 100%;
top: 100%;
height: 100%;
background: #00ff00;
}
#section-3 {
position: absolute;
width: 100%;
top: 200%;
height: 100%;
background: #0000ff;
}

I am trying to create a carousel, where clicking on any element will slide it leftwards, simultaneously sliding the right element into viewport. For that, I need to have the divs stacked side by side. I am trying it out as a float based layout (see Fiddle ).
Problem is that here clicking the red colored div slides it leftward alright, but not the green element leftwards. This is probably due to the fact that they are actually lying below another, as visible when the overflow: hidden is removed from #cont's style. How elese to stack them side by side so that sliding one leftward automatically slides the next one leftwards as well? (Creating the to-be-next element on the fly while clicking and animating it into viewport is a no-no, the element should be present in the DOM!)
I'd suggest you use a plugin, as there is more to this than you may realize. There are many plugins out there for this, here's a list to get you started: http://www.tripwiremagazine.com/2012/12/jquery-carousel.html
I modified your Javascript, HTML, and CSS to get you pointed in the right direction:
http://jsfiddle.net/nf5Dh/2/
You need a container contContent, positioned absolutely, and that container gets moved within the container div. You just float the elements in contContent to get them next to each other.
HTML:
<div id='cont'>
<div id="contContent">
<div id='i1'></div>
<div id='i2'></div>
<div id='i3'></div>
</div>
</div>
CSS:
#cont {
width: 50px;
padding-top: 10px;
background: blue;
height: 50px;
overflow: hidden;
position: relative;
}
#contContent {
height: 50px;
width: 150px;
position: absolute;
top: 0;
left: 0;
}
#contContent > div {
float: left;
display: inline-block;
height: 50px;
width: 50px;
}
#i1 { background: red; }
#i2 { background: green; }
#i3 { background: yellow; }
And the JS:
$("#contContent > div").click(function(){
$("#contContent").animate({left: "-=50px"},1000);
});
You'd probably be better off using an ul instead of all divs, this is at least more semantically correct, though not technically necessary.
<div id="carousel">
<ul id="carouselContent">
<li id="slide1"></li>
<li id="slide2"></li>
<li id="slide3"></li>
</ul>
</div>
This:
#cont {
white-space:nowrap;
overflow: hidden;
}
.pane { // or whatever the slide divs are called. get rid of the float.
float: none;
display: inline-block;
*zoom:1;
*display:inline;
}
You can use that carousel where you can generate javascript for the carousel http://caroufredsel.dev7studios.com/configuration-robot.php
I've used http://sorgalla.com/jcarousel/ for things like this in the past, that's based on postion: relative and left/right offsets. Probably easier than messing with floats.
You can try using a list item instead, and display them inline.
