Consider:
<div class="my-class">
AAA
</div>
I am trying to only skew the shadow, but not the content of the div by putting the shadow into the pseudo-element:
.my-class {
height: 5rem;
width: 10rem;
&::before {
content: "";
box-shadow: 0.2em -0.4rem 0 -0em rgba(0,0,0,0.6);
transform: skew(0, 25deg);
}
}
The example appears in jsbin.
I am obviously misunderstanding something about pseudo-elements, because the shadow doesn't even appear. What am I missing and how can this code be fixed to skew the shadow, but not the text?
There are a couple of things. The pseudo element needs width and height - and the snippet below assumes those are to be the same as its 'owning' element.
Also, where is the element to be placed? This snippet assumes that what is wanted is the shadow skewed but as if it were otherwise the shadow on the main element so it positions it absolutely relative to the main element. Obviously change this if I've misunderstood.
.my-class {
height: 5rem;
width: 10rem;
position: relative;
}
.my-class::before {
content: "";
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
box-shadow: 0.2em -0.4rem 0 -0em rgba(0, 0, 0, 0.6);
transform: skew(0, 25deg);
}
}
<div class="my-class">
AAA
</div>

This is what i am trying to achive
i have :
#image1 {
position: absolute;
bottom: 0px;
align-self: auto;
background-color: #dc022e;
width: 340px;
height: 100px;
border-radius: 50% / 100%;
border-bottom-left-radius: 0;
/*transform: rotate(10deg);*/
border-bottom-right-radius: 0;
opacity: 0.8;
}
#image2 img {
width: 80%;
}
<div>
<div id="image2">
<img src="http://t1.gstatic.com/images?q=tbn:ANd9GcThtVuIQ7CBYssbdwtzZjVLI_uw09SeLmyrxaRQEngnQAked5ZB">
</div>
<div id="image1"></div>
</div>
Finally I don't know how to make it rotated and with the margins cut like in the picture
A Quick example of this would use a pseudo element and have the image set in the background.
div {
position: relative;
height: 300px;
width: 500px;
background: url(http://lorempixel.com/500/300);/*image path*/
overflow: hidden;/*hides the rest of the circle*/
}
div:before {
content: "";
position: absolute; /*positions with reference to div*/
top: 100%;
left: 50%;
width: 0;/*define value if you didn't want hover*/
height: 0;
border-radius: 50%;
background: tomato;/*could be rgba value (you can remove opacity then)*/
opacity: 0.5;
transform: translate(-50%, -50%);/*ensures it is in center of image*/
transition: all 0.4s;
}
/*Demo Only*/
div:hover:before {/*place this in your pseudo declaration to remove the hover*/
height: 100%;
width: 150%;/*this makes the shape wider than square*/
transform: translate(-50%, -50%) rotate(5deg);/*ensures it is in center of image + rotates*/
}
div {/*This stuff is for the text*/
font-size: 40px;
line-height: 300px;
text-align: center;
}
<div>HOVER ME</div>
Instead of nested elements, you can just use a pseudo element. This is placed at the bottom of the container div. For this to work, you need position:relative and overflow:hidden on the container div. Also, pseudo elements always need the content declaration.
To modify the border radius, you just play around with left | width | height of the pseudo element. You don't need any rotation.
Instead of hex color and opacity you can as well use the "new" color space rgba(r,g,b,a) where a is the opacity value.
For the passepartout you simply use the border declaration.
#image2{
position:relative;
border:10px solid #888;
overflow:hidden;
box-shadow:0 0 4px #aaa;
}
#image2::after {
content:"";
display:block;
position: absolute;
bottom: 0;left:-10%;
background-color: #dc022e;
width: 120%;
height: 60%;
border-radius: 100% 100% 0 0;
opacity: 0.8;
}
#image2 img {
width: 100%;
display:block;
position:relative;
}
<div id="image2">
<img src="http://t1.gstatic.com/images?q=tbn:ANd9GcThtVuIQ7CBYssbdwtzZjVLI_uw09SeLmyrxaRQEngnQAked5ZB">
</div>
You can just use position: absolute for your image and position: relative for your overlay, adjusting the top position and width according to your needs. Here's a Fiddle. Hope this helps!
Edit: Here's an updated version of the Fiddle demonstrating border and overflow properties on the img container. As CBroe mentioned, rotating a circle is probably not a good use of your time in this case. Also, I definitely agree that using a pseudo element is a much cleaner approach than nesting images.
Currently working with bootstrap datepicker with to range windows.My task is to fill all dates in selected range. All works fine, but I have this problem:
My CSS classes:
.selected-date-picker-range{
background-color: #0eabec!important;
background-image:none!important;
border-radius: 0!important;
}
.selected-start-position-date-picker {
background-color: #2c7594!important;
background-image: none!important;
border-radius: 50%!important;
}
.selected-end-position-date-picker {
background-color: #2c7594!important;
background-image: none!important;
border-radius: 50%!important;
}
How can I fill white corner spaces in active buttons? Result is have to be like this:
I have tried this code:
border-radius: 25% 0 0 25%!important;
But it's looks not so good. Maybe someone have some idea about that. Thanks for attention.
This jsfiddle shows a possible solution: https://jsfiddle.net/fnrfa9n7/3/
The trick is to add a pseudo-element to selected-start-position-date-picker and selected-end-position-date-picker that has the same background-color as the selected-date-picker-range class, but border-radius applied only to one side of it and a z-index of -1 to move it behind the round parent.
Then the pseudo-element is absolutely positioned within the relatively positioned parent, so that width and height can be 100% of the parent.
.selected-start-position-date-picker,
.selected-end-position-date-picker {
position: relative;
}
.selected-start-position-date-picker:after,
.selected-end-position-date-picker:after {
content: '';
position: absolute;
z-index: -1;
width: 100%;
height: 100%;
background-color: #0eabec;
}
.selected-start-position-date-picker:after {
border-radius: 50% 0 0 50%;
}
.selected-end-position-date-picker:after {
border-radius: 0 50% 50% 0;
}
I wondered if it was possible to create two background-colors for a div an overlay them.
I want a white background-color so that the content below this div doesn't shine through and another rgba() color painted over this white to create lighter colors per script.
Without understanding why you want this, it can be done by using solid color gradients: fiddle.
body {
background: linear-gradient(rgba(220,14,120,0.5), rgba(220,14,120,0.5)),
linear-gradient(white, white); /* first bg is on top of this */
}
Though Adrift's answer is the way to go, you can also use pseudo elements for this.
body {
background: white;
position: relative;
}
body:before {
content: "";
position: absolute;
top: 0;
left; 0;
width: 100%;
height: 100%;
background: rgba(220,14,120,0.5);
z-index: 1;
}
/* Just to be sure, automatically set all elements to a higher z-index than the pseudo element */
body * {
z-index: 2;
position: relative;
}
Here is a fiddle.
However, this is not production friendly:
Setting position relative on body and all other elements when not necessary
Setting unnecessary z-index on all elements
The only upside this method has, is that it doesn't use gradients which, from a semantic standpoint, is more logical.
You can't define two background-colors for one element, but you could overlay one coloured element on top of a white one in order to get a blending effect, while blocking out anything below them:
JSFiddle
HTML
<div class="one">
<div class="two"></div>
</div>
CSS
div {
width: 100px;
height: 100px;
}
.one {
background-color: #fff;
}
.two {
top: 0;
left: 0;
background-color: rgba(0,0,255,0.2);
}
To answer your question, yes there is a way. You can use a background image and a background color on the same div. Check out this SOF post.
Although I would consider a different method like this:
Structure:
<div class="parent">
<div class="white"></div>
<div class="color"></div>
</div>
CSS:
.parent {
position: relative:
}
.white, .color {
position:absolute;
top: 0px;
left: 0px;
}
.white {
z-index: 9998;
}
.color {
z-index: 9999;
}
You can mess around with the details here, but the overall idea is that your layer the divs on top of each other. The div with the higher z-index will be on top. Change their colors accordingly. The parent div being relative will keep the absolute divs inside of that container.
To achieve multiple background colors in CSS, a common proposal is
Solid Color Gradients
But there is an alternative:
Solid Color background-images via SVG Data URIs
The working example below contains the following areas with the following background colors:
<main> - dark-gray
<section> - light-gray
<div class="circle"> - translucent red
In this set-up, we want to use the same theme-color for all the circles, rgba(255, 0, 0, 0.5) but we also want the circles inside the <section> to appear to have the same background-color as the circle outside <section>.
We can observe that, due to the application of the technique below to div.circle.does-not-blend - the rightmost of the two circles inside <section> - that circle ends up with the same apparent background-color as div.circle outside <section>.
The Approach
The approach is to give div.circle.does-not-blend:
the same initial background-color as <main>
an SVG Data URI background-image with the same translucent red background-color as the other .circle elements
The SVG background-image
The SVG Data URI background-image looks like this:
data:image/svg+xml,%3Csvg xmlns="http://www.w3.org/2000/svg" style="background-color:rgba(255, 0, 0, 0.5);"%2F%3E
The Result
In the final result we see that the light-gray background-color of <section> does not bleed through and influence the final background-color of div.circle.does-not-blend
Working Example
main {
display: flex;
justify-content: space-around;
align-items: center;
height: 180px;
padding: 0 9px;
background-color: rgb(127, 127, 127);
border: 1px solid rgb(0, 0, 0);
}
section {
display: flex;
justify-content: space-around;
align-items: center;
flex: 0 0 66%;
background-color: rgb(191, 191, 191);
height: 162px;
}
.circle {
display: inline-block;
width: 120px;
height: 120px;
color: rgb(255, 255, 255);
text-align: center;
line-height: 120px;
background-color: rgb(255, 0, 0, 0.5);
border-radius: 50%;
}
.circle.does-not-blend {
background-color: rgb(127, 127, 127);
background-image: url('data:image/svg+xml,%3Csvg xmlns="http://www.w3.org/2000/svg" style="background-color:rgba(255, 0, 0, 0.5);"%2F%3E');
}
<main>
<div class="circle"></div>
<section>
<div class="circle">Incorrect</div>
<div class="circle does-not-blend">Correct</div>
</section>
</main>
Please see this fiddle, or the code below:
http://jsfiddle.net/MegaMatt3/92G6X/9/
HTML:
<div id="outer">
<div id="inner"></div>
</div>
CSS:
#outer {
border: 1px solid black;
box-shadow: 0 0 20px rgba(0, 0, 0, 1) inset;
height: 200px;
position: relative;
width: 200px;
}
#inner {
background-color: #55A8FF;
bottom: 0;
height: 50px;
left: 0;
position: absolute;
width: 100%;
}
If I have a parent element, with an inset box shadow, and a child element inside it, the child element appears over top of the box shadow. I'd like for the child element to be "underneath" the box shadow, if possible. The effect would essentially show the inset box shadow on top of the child element.
I've messed with the z-index, but with no luck. Is this possible? Any help would be much appreciated. Thanks.
EDIT:
This question is kind of a mess now, but my original question should have indicated that I'm looking for a solution that works when the outer div has a non-transparent background. I've updated my original fiddle and code to reflect this scenario. The other answers here are valid, but the one I've marked as correct works for me in that scenario.
Another solution that works with non transparent backgrounds:
Set the shadow on a pseudo element
CSS
#outer {
border: 1px solid black;
height: 200px;
position: relative;
width: 200px;
background-color: white;
}
#outer:after {
content: "";
box-shadow: 0 0 10px rgba(0, 0, 0, 0.5) inset;
height: 100%;
position: absolute;
width: 100%;
left: 0px;
top: 0px;
}
#inner {
background-color: #55A8FF;
bottom: 0;
height: 50px;
left: 0;
position: absolute;
width: 100%;
}
demo
Set #inner to a negative z-index.
#inner {
background-color: #55A8FF;
bottom: 0;
height: 50px;
left: 0;
position: absolute;
width: 100%;
z-index: -10;
}
http://jsfiddle.net/S8Sm7/
PS:
Remember to close your tags :) just to be safe.
I would add another <div>.
You could use z-index, but if anything else is in the <div> you're going to have modify them all or do some other hack.
I suggest adding another <div> with the shadow. This is a flexible solution.
<div id="outer">
<div id="inner"></div>
<div id="newDiv"></div> // shadow moved to this div
</div>
I had a similar problem here css - box shadow covering all contained divs using absolute positioning
example here: http://jsfiddle.net/92G6X/8/
Due to browser performance implications I can't use box-shadow CSS property because I have many similarly looking elements on my page that should have same looking style including shadow. That's the reason I would like to implement shadows using traditional PNG imagery.
Facts
My elements have predefined and more importantly fixed pixel width
They have fluid height (auto) depending on their content
They have content directly in the element and some child elements will be positioned outside their border
CSS3 can be used but performance-critical parts (gradients, shadows...) should be avoided
CSS pseudo elements can be used without limitation
Requirements
There should be no additional wrapper element added in order to have fluid shadow
Application should run smoothly on mobile browsers - shadows seem to slow down performance significantly on mobile devices since their processing power is much lower than desktop computers.
Possible direction
I thought of using :before and :after pseudos to display top-to-bottom and bottom shadows on the containing element, but these pseudos display within their parent element and positioning parent z-index higher than these children has no effect.
Visual demo of end result
This JSFiddle Demo in pure CSS3 that I would like to achieve but using PNG shadows. In reality there are numerous of these boxes so you can imagine mobile browsers are struggling with all these shadows.
Item is one such box (see blow) that needs PNG shadow. Left menu is child element positioned outside of the box.

Probably I am missing something, but looks like you want something in this way:
demo
The CSS is
.base {
width: 300px;
height: 150px;
font-size: 100px;
font-weight: bolder;
background-color: lightgreen;
position: relative;
z-index: auto;
}
.base:after {
content: '';
position: absolute;
top: 30px;
left: 30px;
background-color: green;
z-index: -1;
width: 100%;
height: 100%;
}
.child {
position: absolute;
left: 150px;
top: 50px;
border: solid 1px black;
color: red;
}
And just change the background of the :after to your image.
I have applied this solution to your fiddle.
The relevant CSS is for the before pseudo element:
.item:before {
content: "";
position: absolute;
top: -10px;
left: -10px;
right: -10px;
bottom: -10px;
z-index: -1;
background-image: url(http://placekitten.com/100/100);
background-repeat: no-repeat;
background-size: 100% 100%;
}
I have used a kitten picture, that is being scaled to cover all the needed size. Just change that to whatever you want.
I needed to do it that way because I had onky a pseudo element available.
The key for that to work (and where you probably had the difficulty) is to add z-index: auto to .item
Updated demo
Well, I had said that it wasn't posible, but I have find a way.
The standard technique would be to use 2 elements, just to avoid stretching the image (as you said). The problem is that we only have 1 pseudo element available.
The solution then would be to use 1 pseudo element, but with 2 backgrounds, to solve the issue.
CSS (only relevant part)
.item:before {
background-image: url(http://placekitten.com/320/10), url(http://placekitten.com/320/500);
background-repeat: no-repeat;
background-size: 100% 9px, 100% calc(100% - 9px);
background-position: left bottom, left top;
}
We will need an image (the first one) only 10 px in height, to cover the bottom shadow. And another one, with enough height to cover the maximumitem posible, and that will be used for the remaining part of the shadow. The dark part is that we need now a calc() height, with limited support. (anyway, better than border image)
