I have prepared a fiddle: https://jsfiddle.net/uj0uhkkq/1/
<div class="papa">
<img src="image.svg" />
</div>
<style>
.papa {
width: 250px;
height: 50px;
}
.papa>img {
max-width: 250px;
max-height: 50px;
}
</style>
In IE 10 and below the image looks like this:
...in any other "recent" Browser the svg has correct proportions.
Is there any way to fix this for IE 10 and below? If not maybe Javascript can calculate the dimensions?
(Why do I not just set the actual height and width of the svg??? Well because I have the img-element load svg-logos of clients dynamically - of course each has different dimensions)
the natural height/width of the svg image is 601x601 (see source for https://upload.wikimedia.org/wikipedia/commons/f/f4/I-8_%28AZ%29.svg), viz a square... so the max-height (or height) and max-width (or width) rules must be the same to maintain the aspect ratio....

I know we can use calc when lengths are defined:
flex-basis: calc(33.33% - 60px);
left: calc(50% - 25px);
height: calc(100em/5);
But what if a length is variable?
height: calc(100% - <<header with variable height>>);
OR
width: calc(100% - 50px - <<box with variable width>>);
Is there a standard way to do this in CSS?
I know the overall task is possible with flexbox and tables, but I'm wondering if CSS offers a simpler method. Flexbox, tables and simple Javascript are acceptable alternatives.

You can use CSS tables:
.wrapper {
display: table;
width: 100%;
margin: 15px 0;
}
.horizontal.wrapper > div {
display: table-cell;
white-space: nowrap; /* Prevent line wrapping */
border: 1px solid;
}
.left { width: 100px } /* Minimum width of 100px */
.center { width: 0; } /* Width given by contents */
.vertical.wrapper { height: 200px; }
.vertical.wrapper > div {
display: table-row;
}
.vertical.wrapper > div > span {
display: table-cell;
border: 1px solid;
}
.top { height: 100px; } /* Minimum heigth of 100px */
.middle { height: 0; } /* Height given by content */
.bottom { height: 100%; } /* As tall as possible */
<div class="horizontal wrapper">
<div class="left">100px wide</div>
<div class="center">Auto width, given by contents</div>
<div class="right">Remaining space</div>
</div>
<div class="vertical wrapper">
<div class="top"><span>100px tall</span></div>
<div class="middle"><span>Auto height, given by contents</span></div>
<div class="bottom"><span>Remaining space</span></div>
</div>
The horizontal case can also be achieved with floats:
#wrapper, .right { overflow: hidden; } /* Establish BFC */
#wrapper > div { border: 1px solid; }
.left, .middle { float: left; }
.left { width: 100px }
<div id="wrapper">
<div class="left">100px</div>
<div class="middle">Auto width, given by contents</div>
<div class="right">Remaining space</div>
</div>
Flexbox can do that.
Support is IE10 and up.

I'm looking for something simple and portable. In the same way a CSS
property can be easily applied across documents, I'm looking for
something similar in terms of ease-of-application for this function.
... isolated fix is preferred.
Horizontal:
This can be achieved using CSS only. As you do not prefer a flex layout solution, the next best bet would be a table layout.
A simple CSS snippet which you could drop into your project (and be done with) would look like this:
div.flexh {
display: table; box-sizing: border-box; padding: 0; margin: 0;
}
div.flexh > div {
display: table-cell; width: auto;
box-sizing: border-box; vertical-align: middle;
}
div.flexh > div:first-child {
/* Override your custom styling below */
min-width: 75px; width: 75px; max-width: 75px;
}
div.flexh > div:last-child { width: 100%; }
You can then add your site-specific styling to this base CSS as per site requirements. Like, nowrap etc.
Two apparent advantages of this solution are:
You do not need to change your markup and also do not need to decorate all children with classes. Just apply the class flexh to your parent div and that would be it.
Minimal Markup Required:
<div class="flexh">
<div>...</div>
<div>...</div>
<div>...</div>
</div>
You are not limited to just three columns. You could have as many columns as need be. The first one will have fixed width, the last one will be flexible, and all the columns in-between would get content-based widths.

<div>Flexible Remaining Width</div>
</div>
Vertical:
This is a bit tricky to achieve without flex layout. A table layout would not work here mainly because, the table-row would not keep a fixed height as required by your use-case. The height on a table-row or table-cell is only an indicative of the minimum height required. If the space is constrained, or the content exceeds the available space, then the cell or row will increase its height depending on the content.
As per the specs here: http://www.w3.org/TR/CSS21/tables.html#height-layout
The height of a 'table-row' element's box is calculated once the user
agent has all the cells in the row available: it is the maximum of the
row's computed 'height', the computed 'height' of each cell in the
row, and the minimum height (MIN) required by the cells...
...the height of a cell box is the minimum height required by the
content
This effect can be seen here: http://jsfiddle.net/abhitalks/6eropud3/
(Resize the window pane and you will see that the first row will increase in height as the content cannot be fit into the specified height, hence defeating the purpose)
Therefore, you can restrict the height indirectly either using inner markup like a div element, or let go of the table-layout and calculate the height for the flexible one. In your use-case, you prefer not to change the markup, hence I am not proposing an inner markup.
The best-bet here would be to use the time-tested model of plain block-level divs with the height of the flexible one to be calculated. As you have already discovered that it is not possible with CSS, you will need a small JavaScript snippet to do that for you.
A simple JavaScript snippet (no jQuery) which you could wrap in a window.load and drop into your project (and be done with) would look like this:
var flexv = document.querySelectorAll('div.flexv');
/* iterate the instances on your page */
[].forEach.call(flexv, function(div) {
var children = [].slice.call(div.children), // get all children
flexChild = children.splice(-1, 1), // get the last child
usedHeight = 0, totalHeight = div.offsetHeight;
children.forEach(function(elem) {
usedHeight += elem.offsetHeight; // aggregate the height
});
/* assign the calculated height on the last child */
flexChild[0].style.height = (totalHeight - usedHeight) + 'px';
});
The CSS snippet is more or less like the horizontal one, sans table layout, which also you could just drop into your project and just add the additional site-specific styling. Minimal markup required remains the same.
Demo Fiddle 2: http://jsfiddle.net/abhitalks/Ltcuxdwf/

usedHeight = 0, totalHeight = div.offsetHeight;

flexChild[0].style.height = (totalHeight - usedHeight) + 'px';
});

Note: As pointed out by #LGSon, the display: inline-table used for the demo does not play well with Firefox. This is only for a demo and should be replaced by either block or inline-block as per your use-case.
Updated
As I commented earlier, and besides flex, this is also solvable using display: table and here is a fiddle demo I made showing that.
If a fixed top also were required for the vertical demo, here is an update of my original display:table version: fiddle demo
Sometimes I haven't been able (or didn't want) to use either flex nor tables, and I have, on and off, looked into making use of css calc() and css attr().
Both come short though, as calc() can only use +-*/ and attr() can only return a string value, which can't be computed by calc().
My suggestion, using plain javascript, is based on that these 2 methods, at some point, might be extended so we can make better use of them.
This is how I would like see them work;
width: calc(100% - attr(this.style.left))
but as they don't, and I can't add it to my css either as it wouldn't validate properly (might even break the parsing, who knows) I added a variant as an attribute on the element instead, with some quirks to make it easier to compute.
And in this case (the 2 demos) it looks like this:
//height
<div id="bottom" data-calcattr="top,height,calc(100% - toppx)">...</div>
//width
<div class="box right" data-calcattr="left,width,calc(100% - leftpx)">...</div>
Together with below script, which by no means is fully developed/tested on all property combinations, it does adjust the div's size.
In short, when runned, it take the attribute, split it into an array, take the first item value as from which property to read, the second to which property to set and the third to which the read value gets inserted/replaced and assigned to the property to be set (hmmm, still working on a better way to express this, but hopefully the script is clear enough with whats going on).
Here is a fiddle showing both the height and width demo, integrated, making use of the same script.
function calcattr() {
var els = document.querySelectorAll('[data-calcattr]');
for (i = 0; i < els.length; i++) {
var what = els[i].getAttribute('data-calcattr');
if (what) {
what = what.split(',');
var rect = els[i].getBoundingClientRect();
var parentrect = els[i].parentNode.getBoundingClientRect();
var brd = window.getComputedStyle(els[i].parentNode,null).getPropertyValue('border-' + what[0] + '-width');
what[2] = what[2].replace(what[0],parseInt(rect[what[0]]-parentrect[what[0]]) - parseInt(brd));
els[i].setAttribute("style", what[1] + ":" + what[2]);
}
}
}
IN CSS
Although I've never tried it, I believe that this would work:
.top {
height:13px;
}
.main {
height:calc(100% - var(height));
}
http://www.creativebloq.com/netmag/why-you-need-use-css-variables-91412904
IN SASS
$top_height: 50px
.main {
height: calc(100% - $top_height)
}
Sass Variable in CSS calc() function
In both cases on container css you should put:
#container {
overflow: hidden;
}
But, it will hide the information that overflows the container. I think that is the point, since you put white-space: nowrap; it means that you don't want to change the height, so you have to hide the text that can't fits the container.
I have this,
I want,
Fiddle
When Seconds tab goes up, I want to decrease height of First Section with min First 2 showing always, same with Second section.
$('#second').resizable({
handles: {
'n': '#ngrip',
},
resize: function () {
var b = $('#second').height();
var a = $('#first').css("height", b + "px");
console.log(a.height());
}
});
Edit
Must have -- I want it to work just like JSFiddle "HTML" and "JavaScript" panels, they both are resizable but also have min heights as you can see here
http://jsfiddle.net/
$('#second').resizable({
handles: {
'n': '#ngrip',
},

minHeight: 150,
resize: function (event, ui) {
var h = ui.size.height;
$('#first').height(400 -h);
}
});

}
#second {
z-index:999;
position: absolute;
}
#first-head, #second-head {
background-color:red;
}
#ngrip {
position: relative;
width: 10px;
height: 10px;

Use minHeight and minHeight option of JqueryUI combined with CSS display: absolute; for #second
First, change your resize direction in HTML (from ui-resizable-s to ui-resizable-n)
<div class="ui-resizable-handle ui-resizable-n" id="ngrip"></div>
Second, use JqueryUI options in Javascript:
$('#second').resizable({
handles: {
'n': '#ngrip',
},
maxHeight: 300, // Example max height of `#second` is 300px
minHeight: 100, // Example min height of `#second` is 100px
resize: function (event, ui) {
// Get height of `#second`
var h = ui.size.height;
// Set height of `#first`
$('#first').height(400 - h); //400 is height of container `#main`
}
});
Final, change some CSS
#main {
width:100%;
height:400px;
overflow: hidden;
position: relative;
}
#first, #second {
height:200px;
width: 100%;
overflow-y: scroll;
}
#second {
z-index:999;
position: absolute;
}
#first-head, #second-head {
background-color:red;
}
#ngrip {
position: relative;
width: 10px;
height: 10px;
background-color: #ffffff;
border: 1px solid #000000;
bottom: -5px;
left: 50%;
}

Explanation
Your second comment was close to all that's required.
The "key insight" is that, in order to constrain the minimum height of one element, it suffices to constrain the maximum height of the other. If the top element cannot be taller than 250, then the bottom element cannot be any smaller than 50 (to maintain a constant container height of 300).
Relevant JavaScript
// initialise dimensions
var containerHeight = $("#container").height();
var minHeight = containerHeight * 0.30; // min 30% height
var maxHeight = containerHeight - minHeight;
// call rebalance once on page load to make sure the panels start off right
rebalance()
$("#top").resizable({
handles: 's',
maxHeight: maxHeight,
minHeight: minHeight,
resize: rebalance // whenever we resize, rebalance the panels
});
function rebalance() {
var currentTopHeight = $("#top").height();
$("#bottom").height(containerHeight - currentTopHeight);
}
I've also taken the liberty of cleaning up your code a little. I think you were having CSS problems related to filling the space after the header, and once that was fixed the resizing is fairly straightforward. I've annotated the CSS with comments to explain what's going on. You might also be interested in the discussion here: Make a div fill the height of the remaining screen space
Relevant CSS
/* both containers are full-width, and absolutely positioned in their parent */
#first, #second {
position:absolute;
width:100%;
}
/* pin the first to the top, and the second to the bottom */
#first {
top:0;
}
#second {
top:50%;
bottom:0;
}
/* The body needs to leave space at the top for the header (25px) but none at the bottom */
#first-body, #second-body {
overflow-y:auto;
width:100%;
position:absolute;
top:25px;
bottom:0;
}
I came across a plugin that looks very promising:
http://nathancahill.github.io/Split.js/
Split.js is a lightweight, unopinionated utility for creating adjustable split views or panes.
No dependencies or markup required, just two or more elements with a common parent.
Views can be split horizontally or vertically, with draggable gutters inserted between every two elements.
There is even a JS Fiddle-style Demo.
Sample JS (from demo):
Split(['#a', '#b'], {
gutterSize: 8,
cursor: 'col-resize'
})
Split(['#c', '#d'], {
direction: 'vertical',
sizes: [25, 75],
gutterSize: 8,
cursor: 'row-resize'
})
Split(['#e', '#f'], {
direction: 'vertical',
sizes: [25, 75],
gutterSize: 8,
cursor: 'row-resize'
})
Sample html usage (from demo):
<div id="a" class="split split-horizontal">
<div id="c" class="split content"></div>
<div id="d" class="split content"></div>
</div>
<div id="b" class="split split-horizontal">
<div id="e" class="split content"></div>
<div id="f" class="split content"></div>
</div>
I'm trying to make a responsive square with the width size based on the (100%) height of the element. I believe it's impossible using only CSS.
The square width should be equal to the height (100% of the large container. The large container is more than 100% of the screen). The ratio has to be width=height to keep the square.
You could do this with a tiny inline image.
No JS, no extra files.
.container {
height: 150px;
width: 100%;
text-align: center;
background: #acd;
}
.square {
display: inline-block;
height: 100%;
background: #691;
}
<div class="container">
<div class="square">
<img src="data:image/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==" height="100%">
</div>
</div>
For a CSS-only solution (where you're sizing relative to the screen size), use viewport units. For example:
#media screen and (orientation:landscape) {
.box{
height: 100vh;
width: 100vh;
}
}
#media screen and (orientation:portrait) {
.box{
height: 100vw;
width: 100vw;
}
}
(You may want to reduce it to 98 units to eliminate scrolling)
Works great for divs that need to take up a precise proportion of screen space.
JSFiddle here.
Take a look... at the aspect-ratio property.
This property makes creating a square div based on height, in the easiest method possible. Here's some example code:
h2 {
font-family: calibri;
}
#parent {
height: 96px;
width: 256px;
background: grey;
margin-bottom: 16px;
}
#child {
height: 80px;
aspect-ratio: 1 / 1;
background: lightgrey;
}
#anotherParent {
height: 96px;
width: 256px;
background: grey;
}
#anotherChild {
height: 50%;
aspect-ratio: 1 / 1;
background: lightgrey;
}
<h2>Absolute height (80px/96px)</h2>
<div id="parent">
<div id="child">
</div>
</div>
<h2>Relative height (50%)</h2>
<div id="anotherParent">
<div id="anotherChild">
</div>
</div>
Here are a couple of links to help you understand the aspect-ratio property:
https://css-tricks.com/almanac/properties/a/aspect-ratio/
https://developer.mozilla.org/en-US/docs/Web/CSS/aspect-ratio
https://support.squarespace.com/hc/en-us/articles/115008538927
Since a square has same width and the height, and you know the width of the square, you can apply the same value to height.
If you can use JS, then please try this: (jQuery)
var wiDth = $('div').css('width'); // get width
$('div').css('height', wiDth); // apply that value to the height
Try it here: http://jsfiddle.net/afzaal_ahmad_zeeshan/vpGUK/
You can accomplish this using javascript. I'm assuming that you have a larger div container, in which you want a square, whose height is the same height as the container. The html is as follows:
<div id="container">
<div id="square" style="height:100%;">
</div>
</div>
In javascript, you would simply do:
<script>
var container = document.getElementById("container");
var square = document.getElementById("square");
square.style.width = container.style.height;
window.onresize=function(){
square.style.width = container.style.height;
};
<script>
Hope that helps
I think this can be a good 'css only' solution for you.
Cross browser working.

Good to highlight this nice css rule:
If the vertical paddings (and margins) are specified in percent (%) values the size is a percent of the width of the containing element.
Put it on your <script src="http://code.jquery.com/jquery-1.10.2.js"></script> and try with jquery:
var totalHeight = 0;
$("#yourContainer").children().each(function(){
totalHeight += $(this).height;
});
$("#yourContainer").css('width', totalHeight + 'px');
Ok here the solution.
<div id="square" style="background-color:black;height:100%">test</div>
$(window).ready(updateWidth);
$(window).resize(updateWidth);
function updateWidth()
{
var square = $('#square');
var size = square.height();
square.css('width',size);
}

You can assign width and height to the container like this
.container {
width: 100vh;
height: 100vh;
}
It will create a square div with 100% height and width=height.
I have a page that displays images at a set width. The height is variable so the image keeps it's aspect ratio. On mouse over, the image changes, but so does the height. How can I keep the height and width the same and just have the new image use a max-height / max-width of the last image so the container is not resized.
See Here - http://jsfiddle.net/z3sxc/11/
<style>
li {
width: 190px;
border: 1px solid black;
list-style: none;
}
li img{
width: 100%;
}
</style>
<body>
<ul>
<li onmouseover="clip_1.src='http://3.bp.blogspot.com/-7VguOKQL_1A/TZCZqkhCJ8I/AAAAAAAAAEc/Hcch-vkZBMk/s1600/01_08_52---Duck_web.jpg'" onmouseout="clip_1.src='http://animal.discovery.com/guides/wild-birds/gallery/mallard_duck.jpg'">
<img src="http://animal.discovery.com/guides/wild-birds/gallery/mallard_duck.jpg" name="clip_1">
</li>
<li onmouseover="clip_2.src='http://3.bp.blogspot.com/-7VguOKQL_1A/TZCZqkhCJ8I/AAAAAAAAAEc/Hcch-vkZBMk/s1600/01_08_52---Duck_web.jpg'" onmouseout="clip_2.src='http://animal.discovery.com/guides/wild-birds/gallery/mallard_duck.jpg'">
<img src="http://animal.discovery.com/guides/wild-birds/gallery/mallard_duck.jpg" name="clip_2">
</li>
</ul>
</body>
You can try this - DEMO
$("li")
.on("mouseover", function() {
var h = $(this).height();
$(this).find("img").prop("src", "http://3.bp.blogspot.com/-7VguOKQL_1A/TZCZqkhCJ8I/AAAAAAAAAEc/Hcch-vkZBMk/s1600/01_08_52---Duck_web.jpg");
$(this).height( h );
})
.on("mouseout", function() {
$(this).find("img").prop("src", "http://animal.discovery.com/guides/wild-birds/gallery/mallard_duck.jpg");
});
No JavaScript/jQuery is needed to achieve this effect.
Simply define the background image of a block element (e.g. <div />, <span style="display: inline-block" />, etc.) in a css class, then change the background image on :hover.
See here: http://jsfiddle.net/adamb/z3sxc/15/
HTML:
<div class="picture" />
CSS:
.picture {
background: url(http://animal.discovery.com/guides/wild-birds/gallery/mallard_duck.jpg) no-repeat;
background-size: 190px;
width: 190px;
height: 190px;
border: 1px solid black;
}
.picture:hover {
background: url(http://3.bp.blogspot.com/-7VguOKQL_1A/TZCZqkhCJ8I/AAAAAAAAAEc/Hcch-vkZBMk/s1600/01_08_52---Duck_web.jpg) no-repeat;
background-size: 190px;
}
You could add a Javascript function to change the CSS on the element:
function changeImage() {
clip_1.style.maxWidth = clip_1.width + 'px';
clip_1.style.maxHeight = clip_1.height + 'px';
clip_1.src='http://3.bp.blogspot.com/-7VguOKQL_1A/TZCZqkhCJ8I/AAAAAAAAAEc/Hcch-vkZBMk/s1600/01_08_52---Duck_web.jpg';
}
<li onmouseover="changeImage()" ... />
(Live here)
Here's something that might get you started.
The first adjustment I made was to wrap your image in a <div> with a generic CSS class name:
<li onmouseover="clip_1.src='http://3.bp.blogspot.com/-7VguOKQL_1A/TZCZqkhCJ8I/AAAAAAAAAEc/Hcch-vkZBMk/s1600/01_08_52---Duck_web.jpg'" onmouseout="clip_1.src='http://animal.discovery.com/guides/wild-birds/gallery/mallard_duck.jpg'">
<div class="clip">
<img src="http://animal.discovery.com/guides/wild-birds/gallery/mallard_duck.jpg" name="clip_1">
<div>
</li>
And then you can give that class some style which will help with the sizing:
.clip {
overflow: hidden;
}
And then with a little jQuery on top:
$(function() {
$('.clip img').load(function() {
$(this).parent('.clip').css({
width: $(this).width(),
height: $(this).height()
});
$(this).unbind('load'); // only do this once
});
});
