like this demo:
http://codepen.io/anon/pen/sorAB
How can i remove the white line between the block when they are rotateX.
Maybe it can without the translate/margin/top property.
Bad english. XD

You can add a border around your blocks :

The problem is that it is difficult to make the div match exactly.
Your layout is exact. However, slight round-outs in dimensions produce that gap between divs.
But, if you increase the sizes, then the corners don't match anymore.
One posible solution is to set a shadow between divs. And make this shadow slightly smaller than the div, so that it won't be visible in the angles:
#girl{
width:300px;height:400px;margin:100px auto 0;
-webkit-perspective:1000;
-webkit-perspective-origin: center center;
}
#girl .item{
height: 100px;width:100%;background-color:#333;
-webkit-transform-origin:top;
-webkit-transform-style:preserve-3d;
box-shadow: 0px 2px 0px -1px #333;
}
#girl .item.i1{-webkit-transform:rotateX(45deg);}
#girl .item.i2{-webkit-transform:translateY(100px) rotateX(-90deg);}
#girl .item.i3{-webkit-transform:translateY(100px) rotateX(90deg);}
#girl .item.i4{-webkit-transform:translateY(100px) rotateX(-90deg);}

Trapezium with css AND with box-shadow

I'm looking at making a trapezium with a box shadow that's 10px wider at the top than the bottom. In the past I've made a trapezium as outlined in the following jsfiddle, but you'll notice that if I put a box-shadow onto the element it boxes the outerWidth in a rectangle, rather than putting a shadow on the slanted border:
#trapezium {
margin:20px auto;
height: 0;
width: 80px;
border-bottom: 80px solid blue;
border-left: 40px solid transparent;
border-right: 40px solid transparent;
box-shadow:0 0 10px #333;
}
http://jsfiddle.net/YhePf/8/
My initial thoughts would be to use something along the lines of:
-webkit-transform:perspective(100) rotateX(1deg);
Something like that. While this certainly begins to resolve the issue, I'm not sure what the number 100 refers to in 'perspective', and how I could calculate a formula that would make sure the top width was precisely 10px wider than the bottom, regardless of how high or wide this element is.
Any tips? Or a third option to pull this off?
What you've built isn't a trapezoid (aka trapezium) -shaped element; it's a rectangle-shaped element where the border styling creates the appearance of a trapezoid. This is why the box-shadow is rectangular.
Using the proprietary -webkit-transform property wouldn't change the shape of the actual element.
To create a truly non-rectangular element, you'll need to use SVG. See Multi-Shaped CSS Layers \ Non-rectangular CSS Layer or non-rectangular hoverable area.

CSS3's box-shadow issue

As I'm developing my webpage, I found an issue using the box-shadow feature.
I want to add a box-shadow to the whole wrapper of my webpage, which contains the header, nav, content and footer.
The nav and content are side by side element.
The problem is, that when I add the box-shadow to the #wrapper, it only appears on the header, as I reproduced here
I was able to fix it by using the side by side elements with the display: table-cell propriety, but it ruined the rest of the page, so I'm asking how could I fix this.
Add overflow:hidden to your wrapper as shown here. It will force your container to wrap the floated elements.
[edit] Without having to add extra markup...
Use CSS clear:both; because you are floating elements to the left, check this out : my fiddle
instead of a wrapper you could simply make another separate with the same size and position and give it a box shadow. change the height to whatever you want, just figure out the height of the content you want to be shadowed.
<style>
div.shadow {
width: 400px;
height: 100%;
position:absolute;
z-index:-99;
box-shadow: 3px 3px 20px #999;
-moz-box-shadow: 3px 3px 20px #999;
-webkit-box-shadow: 3px 3px 20px #999;
}
</style>
<body>
<div class="shadow></div>

CSS dotted border render issue

I'm seeing a rendering issue for a 2px dotted border similar to CSS dotted border issue in adjacent columns in a table rendered as dash in Chrome but on desktop Safari and Chrome. I tried several widths and it happens in all of them
This is a sample:
the vertical line ending has the same issue but it's out of the picture.
Sample:
http://jsfiddle.net/bcdQQ/
This issue happens if the width is not divisible by the border-width.
This works:
http://jsfiddle.net/bcdQQ/5/ (i made it a little bit bigger, for better sight)
#prodpre {
border-bottom: #555 5px dotted;
height: 20px;
margin: 0px 0px 2px 0px;
padding-bottom: 10px;
width: 505px;
}
So, the only possibility to catch this issue, would be a javascript solution, which corrects the width of the div, so it is divisible by the border-width (cause it is dynamically in your example).
could you put it in a smaller container div with overflow hidden?

CSS Drop Shadow for CSS drawn arrow

I want the arrow that appears when a div is hovered here to also drop a shadow. The arrow is drawn from CSS:
.arrow {
position:absolute;
margin-top:-50px;
left:80px;
border-color: transparent transparent transparent #ccff66;
border-style:solid;
border-width:20px;
width:0;
height:0;
z-index:3;
_border-left-color: pink;
_border-bottom-color: pink;
_border-top-color: pink;
_filter: chroma(color=pink);
}
The shadow setting I want to apply is:
-moz-box-shadow: 1px 0px 5px #888;
-webkit-box-shadow: 1px 0px 5px #888;
box-shadow: 1px 0px 5px #888;
-ms-filter: "progid:DXImageTransform.Microsoft.Shadow(Strength=5, Direction=0, Color='#888888')";
filter: progid:DXImageTransform.Microsoft.Shadow(Strength=5, Direction=0, Color='#888888');
The problem in just pasting the shadow setting into the arrow is that the shadow applies to the entire span box and results in a box shadow instead of an drop shadow for the arrow.
P.S. I want to try as much as possible to not use explorercanvas, since I'm trying to minimize script tags in the html. However, if its a must please do provide the code.
Applying the box shadow to the css border triangle will not work, it will only ever apply it to the whole element box.
You can achieve what you are trying to do by changing your css border triangle into a square div, rotating it 45 degrees using css3 and then applying the box-shadow
-webkit-transform: rotate(45deg);
-moz-transform: rotate(45deg);
-o-transform: rotate(45deg);
transform: rotate(45deg);
position: absolute;
Edit:
Updated
Edit:
See the link below for another approach using css content and :after
http://css-tricks.com/triangle-with-shadow/
I haven't tested other browsers, but I noticed that CSS Arrow Please uses a neat little trick
Using this syntax on the parent box will also add a dropshadow to the generated "arrow":
-webkit-filter: drop-shadow(0 1px 4px rgba(0,0,0,0.3));
But using this syntax will not?:
-webkit-box-shadow: 2px 3px 8px 0px rgba(0, 0, 0, 0.04);
Credit to Blowsie for the original answer that led me to the following implementation. Here is a working jsfiddle implementation for Chrome. The relevant CSS:
/* Make an arrow */
.arrow{
background-color: pink;
box-shadow: 3px 3px 4px #000;
width: 30px;
height: 30px;
/* Translate the box up by width / 2 then rotate */
-webkit-transform: translateY(-15px) rotate(45deg);
}​
Caveat
If the content of your box overlaps the arrow then the illusion is broken. You might try working around this by changing the z-index of the arrow to be behind the box but this will cause the box drop-shadow to be rendered on top of the arrow. Add sufficient padding to the box content so that this doesn't happen.
I’m afraid drop shadows only apply to the element box, rather than the angle of the border corners. If you want an arrow like this with a drop-shadow, I’m afraid you’ll have to make it as a PNG image, with the drop shadow in the image.
CSS generally only produces square boxes. The border trick to make a pointy arrow here with CSS is a clever hack.
Another way to achieve arrow with shadow, which will work for all the browsers is to use html triangle character in unicode.
HTML:
<span class="arrow">▶</span>
CSS:
.arrow {
color: red;
text-shadow: 0 0 20px black;
transform: scaleY(1.4)
}
Since that is rendered as regular text you may apply the text-shadow property. For customize the arrow dimensions (want to add extra width or height or skew the arrow) css3 transform property is the key.

CSS margin quirks - please help me understand

When using margin on the child element (h2) why does it give margin to the parent(#box) instead? If I change margin to padding it works as expected.
Did something change or am I missing something? here is my sample code
<html>
<head>
<style>
#box{
border-radius:10px;
-moz-border-radius:10px;
-webkit-border-radius:10px;
height:200px;
width:500px;
background:red;
box-shadow: 15px 15px 12px grey;
-moz-box-shadow: 15px 15px 12px grey;
-webkit-box-shadow: 15px 15px 12px grey;
text-align:center;
margin-top:0;
}
#box h2{
color:#fff;
text-shadow: 2px 2px 2px #000;
margin-top:75px;/*making this padding gives the effect I thought I could achieve with margin*/
height:50px;
width:200px;
}
</style>
</head>
<body>
<div id="box">
<h2>Fun with CSS3</h2>
</div>
</body>
</html>
also if anyone or everyone could share their experience with margin quirks. THx
It's because of collapsing margins. I hate this "feature", but that's the cause of the rendering "issues" you're having. An excerpt from the specs (emphasis is mine):
If the top and bottom margins of a box are adjoining, then it is possible
for margins to collapse through it. In
this case, the position of the element
depends on its relationship with the
other elements whose margins are being
collapsed.
If the element's margins are collapsed with its parent's top
margin, the top border edge of the box
is defined to be the same as the
parent's.
Here's a couple of articles on this subject:
http://reference.sitepoint.com/css/collapsingmargins
http://www.researchkitchen.de/blog/archives/css-autoheight-and-margincollapsing.php
My guess is that you've misunderstood the box model. Margin is the space outside, i.e. around a widget, while padding is space inside, i.e. betweeen the widget's outer border and its content.
You may want to look at this diagram: http://www.w3.org/TR/CSS2/box.html of the box model for reference.
I think it's working OK. Padding does just that: it pads the element its applied to. Margin separates elements from each other. So the margin is working as it should. The position of the h2 tag is where it should be. Giving it a margin would push it away from the root element, which in this case is the body. In order for it to move around in the parent element (the #box div), either you would have to position it relative to the #box element, or give it padding (just one method, but not optimal).
