How to rotate text and position it properly? (CSS, HTML) - html

I am trying to position a rotated headline next to some text. Statically it works very easy with absolute positioning (left picture). I have, however, difficulties when the page gets resized and the positioning fails (right picture).
Current CSS (can be changed):
.headline {
white-space: nowrap;
position: absolute;
top: 185px;
left: -20px;
transform: rotate(270deg);
}
Current HTML structure (can be changed):
<header>
<h1 class="headline">Über mich</h1>
</header>
<div class="text">
<p class="introduction">....</p>
</div>
How can I position the element so that I always stays 20px next to the paragraph?
Could someone link me to existing patterns how to solve this?
A solution with JS (and jQuery) would an option, I would, however, obviously prefer CSS.

Had the same issue. Managed to solve it like this in pure CSS :
.parent {
position: relative;
}
.child {
position: absolute;
transform: translateX(-100%) rotate(-90deg);
transform-origin: right;
left: 30px; /* change this value to match needs */
top: 30px; /* change this value to match needs */
}

The solution was a combination of Diego's answer and Smamatti's comment:
I had to use transform-origin:bottom and width:0. That was working rather quickly, the big problem I had was positioning the text independently to the length of the text. I've only managed to do this by using javascript.
.header
{
margin: 0;
width: 0;
white-space: nowrap;
position: absolute;
text-align: left;
transform-origin: bottom;
margin-top: 280px;
transform: rotate(270deg);
}
Javascript (to ensure compatibility to variables text length):
function adjustSideHeader() {
//check if the headline is visible
if($('h1.headline').length > 0)
{
var headline = $('h1.headline')[0];
var stringLength = headline.textContent.length;
//add style tag to support media queries
document.querySelector('style').textContent +=
"h1.headline { margin-top: " + (stringLength*23.5) + "px; -webkit-transition: margin-top 2s; transition: margin-top 2s;}"
}
}
// fire it when document is loaded
$(document).ready(setTimeout(adjustSideHeader, 300));
Result:

Have you tried moving
<h1 class="headline">Über mich</h1>
inside
<div class="text">?
and set
.text {
position: relative;
}
so that the position is relative to to "text" div. After that you might want to move the Über mich text to the left by reducing it's left value.

Have you tried use position:relative and the margin property?, I suppose it would be something like this:
.headline {
white-space: nowrap;
position: relative; //changed
margin-top: 185px; //changed
margin-left: -20px; //changed
transform: rotate(270deg);
}
*Note: I think you should move the headline inside the paragraph

I have an answer that may be late but worked wonderfully for me.
Normally your text will have a class or id and it will be position:absolute, and positioning values after it, like so:
.TextClass{
position:absolute;
top:50%;
left:55%;
transform:rotate(-90deg);
etc.
However, when you rotate, the positioning becomes relative (as mentioned above).
I found out that by simply putting the rotated text inside a parent div, you can position the (unrotated, position absolute) parent div as much as you want, and then rotate the text (which will be position:relative) inside the parent div, like so:
.divname{
position:absolute;
top:50vh;
left:50vw;
}
.TextClass{
position:relative;
transform:rotate(-90deg);
}

Opacity on background image

As far as I know I can't directly change the opacity of a background image but using ::before and ::after doesn't seem to let my image show up. Am I doing it wrong?

flower window boxes
All of our products come in virtually any length up to 16 feet and two sizes. Our standard size boxes are designed to accommodate almost any flower. Our XL sizes are taller and deeper to provide more root space for plants making them the ideal sized window boxes for plants.

What I've tried
.backimg::after {

opacity: 0.5;
}
.backimg::before{
background-image:url(../images/backimg/wide.png);

}
div::after {
opacity: 0.5;
}
On a side not i know i can simply make the images themselves transparent, but i feel like a code to do it much more useful in the long run. thanks in advance.
::before and ::after require a content property. You can set it to an empty string but it must be included.
In most cases you also need to define a display property and assign some dimensions to the element (unless you are using something like position: absolute; top: 0; bottom: 0; left: 0; right: 0; - in which case, you don't).
.backimg {
background: red;
}
.backimg::after {
content: "";
display: block;
width: 200px;
height: 200px;
background-image: url(http://placehold.it/200x200);
opacity: 0.5;
}
<div class="backimg"></div>
You are missing the .backimg class in your html.
Dont use double :: and add content and display properties to after. Also some dimensions wouldnt hourt (width,height)
.class:after{
Cintent:"";
Display:block; // change as you see fit
}

Chrome Scrollable Div Bug

Interesting bug in Chrome. If a scrollable div is off screen when the page initially loads, then that scrollable div is not scrollable by way of mouse wheel or touch pad gestures until it is given focus (by double clicking somewhere within its element, or selecting text inside of it).
Update
This bug is documented here https://code.google.com/p/chromium/issues/detail?id=417345 It remains unfixed as of May 2015. The thread provides some interesting possible solutions with javascript, but I would like to see if anyone has any alternate suggestions for a fix, possibly not involving JS
The Bug
When you click on the button to "Show Side Container", the side container will slide into view, and the main container will slide out of view. If you immediately try to scroll using the mouse wheel or two finger gesture on a laptop track pad, nothing will happen. You can use page up and page down on the keyboard however, these do work. You can of course also use the actual scroll by by clicking on it with a mouse.
In firefox and IE, you can use the mouse wheel to scroll on this element

$('.side-container').removeClass('side-container-visible');
});
It gets more interesting
If you make the original "page-container" element have enough content that to force it to have overflow, then the "side-container" element no longer displays the aforementioned bug!

Any thoughts on what is happening here are welcome, and any possible fixes would be very welcome.
Came across this question when I encountered a very similar problem with an off-screen menu that moves on-screen when toggled.
Here's the relevant HTML and CSS, simplified:
<div class="menu">
<!-- long list of menu items here -->
</div>
.menu {
position: fixed;
top: 0;
bottom: 0;
left: 0;
transform: translateX(-100%);
transition: transform ease 125ms;
}
.menu--active {
transform: translateX(0);
}
.menu--active is toggled with a button.
Though you're looking for a non-JS solution, I thought I'd post the cleanest workaround I've found in case people end up here with the same problem.
The workaround is to simply force a focus state on the div after the transition has completed. To do this, you first have to give the div a tabindex so that it can be focused.
<div class="menu" tabindex="-1">
<!-- long list of menu items here -->
</div>
(A value of -1 should keep the div out of the normal tab order.)
Then, using a bit of delayed jQuery, focus on the div. This should be invoked along with whatever logic you use to "activate" your div.
setTimeout( function() {
$('.menu').focus();
},150);
The time here is 150 milliseconds, which is just after the transition should have completed. A value equal to that of the transition duration would probably work too, but I set it longer just to be safe.
A more complete example might be:
$('.menuButton').on('click', function() {
$('.menu').addClass('menu--active');
setTimeout( function() {
$('.menu').focus();
},150);
});
Finally, you probably won't want the focus outline on the focused div, so you might choose to remove it with an outline: none in the style rule for your div. In my project, but not in the original example in the question, this actually broke focus on the div, and it went back to being un-scrollable. So I did this instead:
.menu:focus {
outline-color: transparent;
}
I forked the original example and included this solution here: http://codepen.io/johntobinme/full/MaPMgY
You have overflow-y set to auto, meaning it will create a scroll bar for off screen content. Since .large-content has such a large height, it goes off screen. Simply set overflow-y to none and this will no longer occur. Not a bug, just user error.

Get image in front when mouseover HTML

I have many images button in div and I want when I over mouse in an image it change the scr and show the same image but highlighted with border.
Like here show before /after :
It work fine but when I have all other images together it show like that :
I think i need to set the image when the mouse over to be in front ;any idea?
Update :
code:
<div id="mymap" width="720" style="width: 920px; height: 1227px; position: relative; left: 250px; transform: scale(.5,.5); -ms-transform: scale(.5,.5); -webkit-transform: scale(.5,.5); -o-transform: scale(.5,.5); -moz-transform: scale(.5,.5);">
<img id="Burimi" style="position: absolute; left: 10px" src="Images/Reagion/Burimi-B.png" onmouseover="this.src='Images/reagion/Burimi-A.png'" onmouseout="this.src='Images/reagion/Burimi-B.png'" />
<img id="N Batinah" style="position: absolute; left: 98px; top: 1px;" src="Images/Reagion/N Batinah-B.png" onmouseover="this.src='Images/reagion/N Batinah-A.png'" onmouseout="this.src='Images/reagion/N Batinah-B.png'" /></dive>
using simple CSS you should be able to change the z-index property. Assuming that the element is positioned either absolute or relative, just use
#mymap img:hover { z-index: 9999; }
#image:hover{
position: relative;
z-index: 2;
background-image: url('image2.png');
}
assuming #image is your image container , and image2.png is your hover-state image (while your are using background on container for all elements on the map, not just plain img tags).
It'll be quite dodgy though with detecting the hover on a correct elements.
use the selector ":hover" to change your css when the mouse over

Is it possible to show a div on click using the :active selector in CSS?

I'm looking to show a div on click. The goal is to use pure CSS only, no jQuery.
Working FIDDLE Demo
Consider that you want something like this:
We write our markup as simple as possible. One element for container, one element for our link and one another element for popup:
<!-- [container] -->
<div class="link-with-popup">
<!-- link -->
<div class="link">CSS</div>
<!-- [popup] -->
<div class="popup">
<div class="box">CSS Description</div>
</div>
<!-- [/popup] -->
</div>
<!-- [/container] -->
Here is our layer structure in picture:
CONTAINER
Let's write CSS for our container.
.link-with-popup {
/* for visualizing */
background: yellow;
/* we need relative, because childs are absolute */
position: relative;
margin-bottom: 10px;
height: 30px;
width: 400px;
}
[!] Note that we make our container relative. Because the children will be in absolute mode.
LINK
We create our link as an absolute element from left, just as shown in the figure above.
.link {
background: blue;
position: absolute;
top: 0;
left: 0;
bottom: 0;
width: 100px;
z-index: 10;
}
POPUP
The dimention of popup element is same as the container, so we set all top, left, right, bottom properties to 0.
.popup {
position: absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;
background: green;
z-index: 20;
}
[!] Note that z-index of popup element must be greater than link element.
.popup {
/* we won't show the popup yet */
display: none;
}
By now, we'll get this result (check it on jsFiddle):
Now we want the click for our link. This must be done with :active pseudo selector in CSS. But how we must show the poup? We have to get the next sibling element by the link. We use the + selector in CSS:
.link:active + .popup {
display: block;
}
See the result on jsFiddle. But the problem is that when user realize the mouse, the popup will disappear (as it display is set to none).
So we set the :hover rule for the popup and make it block.
.popup:hover {
display: block;
}
Check the jsFiddle demo. Now we get close enough. The only issue that the popup element, hide our link.
But it doesn't matter, because we won't set background for our popup (it will be transparent).
TEXT
For wanted text in popup element, we set this rules:
.popup .box {
position: absolute;
/* note that we make a gap from left to don't hide the link */
left: 130px;
top: 0;
right: 0;
bottom: 0;
background: #505050;
}
Check the jsFiddle demo. Now we have all things that we need.
Now it's time to make our popup element transparent (by setting the background as transparent or simply remove the background: green; rule):
.popup {
background: transparent;
}
And here is the final jsFiddle result. And if you add some extra CSS to it, it can be more stylish. Something like this that I've created.
Some important note to memorize:
In the final result, there is a gap between the link (blue one) and the popup (gray one). But the fact is that the gray element is not our popup. It's a child of popup and our popup is an 100% width and height element on the container.
Working FIDDLE Demo
Another way is to use the :target property (only works in moderns browsers).
Here's a qucik DEMO where I've hidden the div by applying opacity: 0; and the when you click the link the div changes to opacity: 1; The link and the div are matched using a hash in the url.
Here's the code from my example.
HTML
Click me
<br />
<div id="pop"></div>
CSS
#pop {
width: 100px;
height: 100px;
background: #000;
opacity: 0;
}
#pop:target {
opacity: 1;
}
There are some side effects though. The browser will jump/scroll down (not sure if it's possible to prevent this?) to the matched div and since we are using a hash in the url it will effect the browser history and, as mentioned above, it only works in modern browsers.
EDIT If you want to look into other hack/tricks for pure CSS click events, this is a good post - http://tympanus.net/codrops/2012/12/17/css-click-events/

180 degree rotated div is only clickable from one side

I've run into a rather strange problem. I have a div that is rotatable via CSS3. The div has a front div child and back div child, with the back div having -webkit-transform: rotateY( 180deg ) set.
The problem that once the parent element is rotated to display the back side of the div, it will only detect clicks of child elements on exactly one side of the div, specifically the second half of the div or right side. The front side div detects clicks on the entire face of element. Also, the z-indexes are fine. I assume that the issue may be due to the rotation and the browser displaying one half of the side "closer"?
The code that this is breaking is extremely complex, so I created a test file to demonstrate the problem below. I'm using a jQuery plugin I wrote for the 3D transformations, which can be found here https://github.com/pwhisenhunt/jquery.transform/blob/master/jquery.transform.js.
Edit: After experimentation, the clicking of the button element is only registering from 100-200px and not from 0-100px. In other words, it is in fact only registering on the second half of the div.
Any help is very much appreciated!

A JSFiddle Example of the Problem - Can be found HERE!
I know this reply is a bit too late for most of us here, but I ran into this problem earlier today, and none of the replies helped me solve it.
Solution by #kristiankeane made the other half non-clickable. I was using a container for the wrapper as well. Turns out, it's an odd bug in webkit, and I was able to fix it and make 100% of the element clickable by changing transform: rotateY(180deg) to transform: rotateY(-180deg)
It's really odd, and I don't know how it worked, but it did. I hope this helps someone!
I had this exact same issue, was able to fix it by slightly changing the parent rotation when flipped - I changed
`.flip-holder.flipped {
-webkit-transform: rotateY(180deg);
-moz-transform: rotateY(180deg);
transform: rotateY(180deg);
}`
to
`$.flip-holder.flipped {
-webkit-transform: rotateY(180.5deg);
-moz-transform: rotateY(180.5deg);
transform: rotateY(180.5deg);
}`
and the entire backface (plus overflowed elements positioned absolutely) were now clickable, and the browser did not render the extra 0.5deg of rotation so text and images are clear.
Translate both front and back just a little bit and they won't overlap.
Example:
.element .front {
-webkit-transform: translateZ(1px);
}
.element .back {
-webkit-transform: rotateY(180deg) translateZ(1px);
}
it seems that you are missing a container (in much the same way I was missing it).
see the official documentation
it's not the outer element being flipped, but a wrapper inside it. that in turn causes one of two divs to be displayed (and the transition to occur)
If your flip card structure is like this:
<div class="flipcard">
<div class="flipcard-front">
</div>
<div class="flipcard-back">
</div>
</div>
then add this to your CSS:
.flipcard:hover {
pointer-events: none;
}
.flipcard-back:hover {
pointer-events: auto;
}
could It be (and I'm just speculating) that you should use a live or delegate event bind instead of the regular. I'm speculating the click event maybe 'remembers' some how the original div position without the rotating.
After all tricks as rotate to back and rotate to 180.5 and other...
problem fixed only the following way:
When the rotation ends - create new element, clone html from rotated element, and insert new element instead of old
