Identical elements have different scrollHeights when overflowed. What is the cause, and how can I fix it?

I have a plugin that creates and, on an interval, populates a <p> with the content of a <textarea>. The plugin positions the <p> underneath the <textarea>, and styles the elements so that their "boxes" are identical. Additionally, the background and text of the <textarea> are defined as transparent so that the content of the <p> can be seen.
Ideally, the elements and their contents will mirror one another at all times. And in most cases, they do. However, when both elements are made to be scrollable, the dynamic breaks; this is due to a difference in the scrollHeight of the two elements (the scrollHeight of <textArea> is larger than that of the <p>)
Here is the code:
var $shadowParagraphObj = $("#shadowParagraph");
var $contentTextAreaObj = $("#contentTextArea").scroll(scrollShadowParagraph);
function scrollShadowParagraph(event)
{
var textAreaScrollLeft = $contentTextAreaObj.scrollLeft();
var textAreaScrollTop = $contentTextAreaObj.scrollTop();
if($shadowParagraphObj.scrollLeft() != textAreaScrollLeft)
$shadowParagraphObj.scrollLeft(textAreaScrollLeft)
if($shadowParagraphObj.scrollTop() != textAreaScrollTop)
$shadowParagraphObj.scrollTop(textAreaScrollTop)
}
var intervalId = setInterval(function(){$shadowParagraphObj.html($contentTextAreaObj.val())}, 100);
#containerDiv {
position: relative;
left: 50%;
margin-left: -250px;
width: 510px;
height: 200px;
}
#shadowParagraph, #contentTextArea {
width: inherit;
height: inherit;
overflow: scroll !important;
padding: 4px;
border : none;
outline: none;
margin: 0px;
white-space: pre-wrap;
word-wrap: pre-wrap;
font: 1em Arial, sans-serif;
}
#shadowParagraph {
position: absolute;
z-index: 0;
background: white;
color: blue;
}
#contentTextArea {
position: relative;
z-index: 1;
background: transparent;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id='containerDiv'>
<p id='shadowParagraph'></p>
<textarea id='contentTextArea'></textarea>
</div>
Overflowing the <textarea> should produce the issue (the text of the <textarea> has been given color to make the issue easy to see).
Have I forgot to declare some properties that are causing this discrepancy between scrollHeight values? If so, what are they and how should I declare them? If not, is there any way to ensure that the scrollHeight of the two elements is equal at all times?

Okay so using .replace(/\n\r?g, '<br />') to convert updated values, your line breaks will be converted into html line breaks. Additionally, html tends to ignore lone <br /> line breaks, so you will want to add an additional <br /> to the value to ensure the last line break is rendered.
Put together this would look something like:
var textAreaHTML = $myTextArea.val().replace(/\n\r?g, '<br />')+'<br />';
Additionally, I would recommend updating your textarea values AND scroll position on the .keyup() event, .keypress() event, or both events using .on('keyup keypress', function() {...}).

Setting a length (height or width) for one element minus the variable length of another, i.e. calc(x - y), where y is unknown

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.

<p>Variable ContentWidth</p>
</div>
<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/

document.addEventListener("load", flexit);
function flexit(e) {
var flexv = document.querySelectorAll('div.flexv');

flexChild = children.splice(-1, 1),
usedHeight = 0, totalHeight = div.offsetHeight;

usedHeight += elem.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.

Child Element Moves Baseline

I have a dropdown widget that can be used inline, but when it opens it seems to lower the text baseline. I would have expected the children of the widget not to affect layout.
With some experimentation, I found that it matters whether or not there is text in the div, so there are two widgets in the following example.
var divs = document.querySelectorAll('div div');
for (var i = 0; i < divs.length; i++) {
divs[i].addEventListener('click', function() {
this.classList.toggle('high')
});
}
div {
background-color: #ddf;
width: 150px;
height: 20px;
overflow: visible;
display: inline-block;
}
.third {
display: block;
}
.high {
height: 100px;
}
<div>
<div></div>
</div>
<div>
<div>Text</div>
</div>
<div>
<div class="third"></div>
</div>Text
It seems like the inner div is treated like text if there is not actual text. Is there a way to eliminate this behavior?
I can only change the divs and not what follows, so I'd be interested in a solution that allows me to make the parent div solely determine the baseline.
EDIT: Not making the child display: inline-block also seems to work. This seems to confirm that the contents are being treated as the "text" that matters. I'd still like to know why.

does this solve your problem. I added only float: left to the <div> 's. Here's Fiddle <http://jsfiddle.net/zlajaa1/ffebcww0/>

Javascript show hide css/html/js problem

Some code when I call a showhide method in html is not working correctly. The method shows then hides some html content on this webpage, however, the html or css is not functioning correctly. For example, when the page is loaded in a browser, the space where the div will be shown is just empty space, when there shouldn't be space at all, but when the div is shown it just fills that space. The I think it could be something to do with the css, however I am not to sure. Here is the CSS id I am using to show and hide.
#showAndHide {
text-align: justify;
height: auto;
width: 700px;
margin: auto;
position: relative;
padding-top: 10px;
padding-bottom: 10px;
padding-left: 20px;
padding-right: 10px;
visibility: hidden;
}
and here is a small sample of the html that this is being applied to.
<div id="showAndHide">
<div id="physicalAdress">
<div class="h4">
<h4> What is your physical address? </h4>
</div>
<p> Property name (if you have one) </p>
<input type="text" name="propertyName" /><br/>
that html is within the showandhide div, then within a user input div which is:
.userinput {
text-align: justify;
height: auto;
width: 700px;
margin: auto;
position: relative;
border-collapse: collapse;
padding-top: 10px;
padding-bottom: 10px;
padding-left: 20px;
padding-right: 10px;
border-right-style: solid;
border-left-style: solid;
}
here is the Javascript method.
function showHideDiv()
{
var divstyle = new String();
divstyle = document.getElementById("showAndHide").style.visibility;
if(document.getElementById("yesPrint").checked == true)
{
document.getElementById("showAndHide").style.visibility = "visible";
}
if(document.getElementById("noPrint").checked == true)
{
document.getElementById("showAndHide").style.visibility = "hidden";
}
}
Basically when I run the page, and show the content the styling is becoming skewed and the positioning of the html that is not with the show and hide content is also becoming skewed.
Any ideas/help would be appreciated.

use display:none instead of visibility: hidden;.
visibility: hidden; reserves space for element

Change visibility:hidden to display:none to prevent the element from taking up space when hidden.
You may need to change your JavaScript slightly, but I can't say for sure as you haven't posted it, but you're going to need something like this:
element.style.display = "block"; //Show the element

function toggle_show(id) {
var el = document.getElementById(id);
if (el && el.style) {
el.style.display = el.style.display == 'none' ? 'block' : 'none';
}
}

http://webdesign.about.com/od/css/f/blfaqhidden.htm
Quoting webdesign:
"visibility: hidden hides the element, but it still takes up space in the layout.
display: none removes the element completely from the document. It does not take up any space, even though the HTML for it is still in the source code."

Position badge over corner of image automatically

I have a layout where images "float" within a certain area. The layout looks like this:
The source like this:
<div class="free_tile">
<a class="img_container canonical" href="/photos/10">
<img class="canonical" src="http://s3.amazonaws.com/t4e-development/photos/1/10/andrew_burleson_10_tile.jpg?1303238025" alt="Andrew_burleson_10_tile">
<!-- EDIT: I am aware that I can put the badge here. See the edit notes and image below. -->
</a>
<div class="location">Houston</div>
<div class="taxonomy"> T6 | Conduit | Infrastructure </div>
</div>
The CSS looks like this (in SCSS):
div.free_tile { width: 176px; height: 206px; float: left; margin: 0 20px 20px 0; position: relative;
&.last { margin: 0 0 20px 0; }
a.img_container { display: block; width: 176px; height: 158px; text-align: center; line-height: 156px; margin-bottom: 10px; }
img { margin: 0; border: 1px solid $dark3; display: inline-block; vertical-align: middle; #include boxShadow;
&.canonical { border: 1px solid $transect; }
}
.location, .taxonomy { width: 176px; }
.location { font-weight: 700; }
.taxonomy { line-height: 10px; font-size: 10px; text-transform: uppercase; height: 20px; overflow: hidden; }
}
div.transect_badge { height: 20px; width: 20px; background: url('/images/transect-badge.png'); }
So, basically the images are sitting vertically-aligned middle and text-aligned center, and they have a maximum width of 176 and max height of 158, but they're cropped to maintain the original aspect ratio so the actual top corner of each image falls differently depending on which image it is.
I have a badge that I'd like to put in the top corner of certain images (when the image is "canonical"). You see the style for this above (div.transect_badge).
The problem, of course, is I don't know where the top corner of the image will be so I can't hardcode the position via CSS.
I assume that I'll need to do this via jQuery or something. So, I started with a jQuery method to automatically append the badge div to any canonical images. That works fine, but I can't figure out how to position it over the top left corner.
How can this be done? (ideally using just HTML and CSS, but realistically using JS/jQuery)
--EDIT--
Here's the problem: The image is floating inside a container, so the corner of the image might fall anywhere inside the outer limits of the container. Here's an example of what happens if I try to use position:absolute; top:0; left:0 inside the same container the image is bound by:

It took some tryouts, but here it is: the size independent image badge positioner.
HTML:
<div class="tile">
<span class="photo">
<img src="/photos/10.jpg" alt="10" /><ins></ins>
</span>
<p class="location">Houston</p>
<p class="taxonomy">T6 | Conduit | Infrastructure</p>
</div>
CSS:
.tile {
float: left;
width: 176px;
height: 206px;
margin: 0 20px 20px 0;
}
.photo {
display: block;
width: 176px;
height: 158px;
text-align: center;
line-height: 158px;
margin-bottom: 10px;
}
a {
display: inline-block;
position: relative;
line-height: 0;
}
img {
border: none;
vertical-align: middle;
}
ins {
background: url('/images/badge.png') no-repeat 0 0;
position: absolute;
left: 0;
top: 0;
width: 20px;
height: 20px;
}
Example:
In previous less successful attempts (see edit history), the problem was getting the image vertically centered ánd to get its parent the same size (in order to position the badge in the top-left of that parent). As inline element that parent doesn't care about the height of its contents and thus remains to small, but as block element it stretches to hís parent's size and thus got to high, see demonstration fiddle. The trick seems to be to give that parent a very small line-height (e.g. 0) and display it as an inline-block. That way the parent will grow according to its childs.
Tested in Opera 11, Chrome 11, IE8, IE9, FF4 and Safari 5 with all DTD's. IE7 fails, but a center-top alignment of the photo with badge at the right position isn't that bad at all. Works also for IE7 now because I deleted the spaces in the markup within the a tag. Haha, how weird!

EDIT3: This solution is very similar to my original solution. I didn't really look at your code much so I should have noticed this earlier. Your a tag is already wrapping each image so you can just add the badge in there and position it absolute. The a tag doesn't need width/height. Also you must add the badge image at the beginning of your a tag.
Demo: http://jsfiddle.net/wdm954/czxj2/1/
div.free_tile {
width: 176px;
height: 206px;
float: left;
}
a.img_container {
display: block;
margin-bottom: 10px;
}
span.transect_badge {
display:block;
position: absolute;
height: 20px;
width: 20px;
background-image: url('/images/transect-badge.png');
}
HTML...
<a class="img_container canonical" href="/photos/10">
<span class="transect_badge"></span>
<img class="canonical" src="path/to/img" />
</a>
Other solutions...
In my code I'm using SPAN tags so simulate images, but it's the same idea. The badge image, when positioned absolute, will create the desired effect.
Demo: http://jsfiddle.net/wdm954/62faE/
EDIT: In the case that you need jQuery to position. This should work (where .box is your container and .corner is the badge image)...
$('.box').each(function() {
$(this).find('.corner')
.css('margin-top', ( $(this).width() - $(this).find('.img').width() ) / 2);
$(this).find('.corner')
.css('margin-left', ( $(this).height() - $(this).find('.img').height() ) / 2);
});
EDIT2: Another solution would be to wrap each image with a new container. You would have to move the code that you use to center each image to the class of the new wrapping container.
Demo: http://jsfiddle.net/wdm954/62faE/1/
$('.img').wrap('<span class="imgwrap" />');
$('.imgwrap').prepend('<span class="badge" />');
Technically you can just add something like this to your HTML though without using jQuery to insert it.

Use an element other than <div>, e.g. <span> and put it inside your <a> element after the <img> element. Then, give the <a> element position:relative; and the <span> gets position:absolute; top:0px; left:0px;. That is, if you don't mind the badge also being part of the same link - but it's the easiest way. Also, the reason for using <span> is to keep your HTML4 valid, <div> would still be HTML5 valid, however.

I did find one solution using jQuery. I don't prefer this because it noticably impacts page loading, but it is acceptable if nothing else will work. I'm more interested in NGLN's idea which seems promising but I haven't entirely figured out yet. However, since this thread has picked up a lot of traffic I thought I'd post one solution that I came up with for future readers to consider:
Given this markup:
<div class="free_tile">
<a class="img_container canonical" href="/photos/10">
<img class="canonical" src="http://s3.amazonaws.com/t4e-development/photos/1/10/andrew_burleson_10_tile.jpg?1303238025" alt="Andrew_burleson_10_tile">
<span class="transect-badge"></span>
</a>
<div class="location">Houston</div>
<div class="taxonomy"> T6 | Conduit | Infrastructure </div>
</div>
Same CSS as in question except:
span.transect-badge { display: block; height: 20px; width: 20px; position: absolute; background: url('/images/transect-badge.png'); }
Then this jQuery solves the problem:
$(function() {
$('img.canonical').load( function() {
var position = $(this).position();
$(this).next().css({ 'top': position.top+1, 'left': position.left+1 });
});
});
Like I said, though, this incurs noticeable run-time on the client end, so I'd prefer to use a non JS solution if I can. I'll continue to leave this question open while I test out and give feedback on the other solutions offered, with hopes of finding one of them workable without JS.
