I am trying to build a DIV with cut corners, like so:
I only managed to do the top right corner using a tutorial and here is the code:
.lifeatblock {
background-color: #435973 !important;
position:relative;
}
.lifeatblock:after {
content: '';
border-style: solid;
border-width: 0 50px 50px 0;
border-color: transparent #fff transparent transparent;
width: 0;
height: 0;
right: 0;
top: 0;
position: absolute;
}
I've tried building the bottom left corner using :before and I've failed. Does anyone know how I can do this? Thanks.
it can be done with pseudo element like this!
*{
margin:0;
padding:0;
}
.box{
background-color:blue;
width:400px;
height:200px;
position:absolute;
top:50%;
left:50%;
transform:translate(-50%,-50%)
}
.box:before, .box:after{
content:"";
position:absolute;
width: 0;
height: 0;
border-left: 30px solid transparent;
border-right: 30px solid transparent;
border-bottom: 30px solid white;
}
.box:before{
transform:rotate(-135deg);
left:-20px;
bottom:-12.5px;
} .box:after{
transform:rotate(45deg);
right:-20px;
top:-12.5px;
}
<div class="box"></div>

I want to ask how can i create a css arrow triangle with smooth sides i.e. no cut in the side of arrow without using any image? I have already tried the tutorial -
[http://css-tricks.com/snippets/css/css-triangle/][1]
.arrow_up
{
width: 0;
height: 0;
border-left: 10px solid transparent;
border-right: 10px solid transparent;
border-bottom: 10px solid black;
position:absolute;
top:75px;
left:250px;
}
<div class="arrow_up"></div>
UPDATE
Sorry, the issue was found only in some older version of Firefox.
You need to use a pseudo element and rotate it:
DEMO
CSS:
.arrow_up
{
width: 100px;
height: 50px;
position:absolute;
top:150px;
left:250px;
overflow:hidden;/* hide part of the pseudo overflowing*/
}
.arrow_up:before {
content:'';
position:absolute;
width:100%;
padding-top:100%;/* it will draw a square , change this value for other degrees angles*/
transform:rotate(45deg);/* we'll see a corner */
background:black;
top:20px;/* tune this according to size of parent or size to be seen */
}
Do not forget to add vendor-prefix or use a script that adds them automaticly.
The use o a pseudo element allows to add content in the box : ie. http://codepen.io/gc-nomade/pen/gdoGA
The only thing I can possibly think of is that you have another element on the page which is slightly overlapping onto the arrow as when tested it works fine:
http://jsfiddle.net/Hive7/qLAg4/
.arrow_up {
width: 0;
height: 0;
border-left: 50px solid transparent;
border-right: 50px solid transparent;
border-bottom: 50px solid black;
position: absolute;
top: 75px;
left: 250px;
}
It could be something to do with your browser as well though
Is it possible to recreate a box like this without using background images and only one element?
Ideally, I'd be able to control which corners are darkened by adding a class, so the above image might be class="box dark-top dark-left dark-bottom dark-right". I can darken two by using :before and :after, but am having problems thinking of a good way to darken three or four corners without adding additional markup.
Here's a way to darken all four corners with one element, though I haven't figured out how to darken specific corners yet. But my theory was to have the original border as the dark border, and then /lighten/ the sides of the box with pseudo-elements.
Fiddle: http://jsfiddle.net/KZSLH/
.box {width:236px; height:236px; border:1px solid #333; position:relative;}
.box:before {content:""; display:block; width:200px; height:236px; position:absolute; top:-1px; left:18px; border-top:1px solid #ccc; border-bottom:1px solid #ccc;}
.box:after {content:""; display:block; width:236px; height:200px; position:absolute; top:18px; left:-1px; border-left:1px solid #ccc; border-right:1px solid #ccc;}
It's far from perfect, but this is the only way I could think of to do something like that... You'll want to play around with the border thickness, border radius and which borders are rounded to really have it suit your needs
The only thing I couldn't figure out is how to get the edges of the corners to be sharp rather than tapering off... Maybe someone could contribute that part?
First, start off with two overlapping div elements:
<div id="thick" />
<div id="thin" />
Then, use rounded corners and relative positioning to taper off and create the "bold" corners.
#thick {
position:absolute;
top:50px;
left:50px;
height:100px;
width:100px;
background-color:white;
border:3px solid black;
}
#thin {
position:relative;
top:-2px;
left:-2px;
height:104px;
width:104px;
background-color:white;
border-radius: 15px;
}
Here is a fiddle: http://jsfiddle.net/bGrdA/
And credit to this post for giving me the idea.
I think I figured it out. The key is that there must be content inside of the box in it's own element, which will always be the case my scenario.
Example: http://jsfiddle.net/n7pgP/
The classes that can be added to the box are:
dtl = darken top left
dtr = darken top right
dbl = darken bottom left
dbr = darken bottom right
Some thing this can be tried out for two elements
http://jsfiddle.net/V8jmR/
#content {position:relative;width:400px;height:300px;}
#content:before, #content:after, #content>:first-child:before, #content>:first-child:after {
position:absolute;
width:80px; height: 80px;
border-color:red; /* or whatever colour */
border-style:solid; /* or whatever style */
content: ' ';
}
#content:before {top:0;left:0;border-width: 1px 0 0 1px}
#content:after {top:0;right:0;border-width: 1px 1px 0 0}
#content>:first-child:before {bottom:0;right:0;border-width: 0 1px 1px 0}
#content>:first-child:after {bottom:0;left:0;border-width: 0 0 1px 1px}
Original answer
CSS - show only corner border
The only possibility I know is in using additional elements:
<div class="box">
<span class="darkTopLeft"></span>
<span class="darkTopRight"></span>
<span class="darkBottomLeft"></span>
<span class="darkBottomRight"></span>
</div>
.box {
background-color: #fff;
border: 1px solid #ccc;
height: 100px;
position: relative;
width: 100px;
}
.box > span {
height: 10px;
position: absolute;
width: 10px;
}
.darkTopLeft {
border-left: 1px solid #000;
border-top: 1px solid #000;
left: -1px;
top: -1px;
}
.darkTopRight {
border-right: 1px solid #000;
border-top: 1px solid #000;
right: -1px;
top: -1px;
}
.darkBottomLeft {
bottom: -1px;
border-bottom: 1px solid #000;
border-left: 1px solid #000;
left: -1px;
}
.darkBottomRight {
bottom: -1px;
border-bottom: 1px solid #000;
border-right: 1px solid #000;
right: -1px;
}

I'd like to produce a circle with the outer dashed border offset from the main circle. I've attached a pic for reference.
I have tried using box shadow to achieve this but no luck so far. Is there a way to do this?
I was able to get this effect by utilizing the pseudo-element selector ::before. (::after would work just as well)
Here is a DEMO
Given the element:
<div class="circle"></div>
Apply the following CSS rule:
.circle {
position: relative;
float: left;
border: 2px dotted black; /* This is the outer border (dotted) */
background-color: white; /* This is the color of the inner border */
padding: 10px; /* This is the size of the inner border */
border-radius: 50%;
}
.circle::before {
position: absolute;
display: block;
content: ' ';
background-color: #6abde7; /* This is the color of the inner circle */
width: 150px; /* This controls how wide the circle will be. Remember to subtract padding + border */
height: 150px; /* This controls how tall the circle will be. Remember to subtract padding + border */
border-radius: 50%;
}
You can adjust a few of the rules above. They are mainly there just to give shape to the circle for the demo. I've commented the ones that control the styles of the circle.
Explanation
You're basically adding an element inside of the container element via CSS. This won't work on elements that don't support content. (i. e. <input>)
DEMO
.circle {
height:200px;
width:200px;
border-radius:50%;
background-color:#cef;
border:3px dotted #000;
box-shadow:inset 0 0 0 10px #fff;
}
UPDATE
Using :after
DEMO
.circle {
height:200px;
width:200px;
border-radius:50%;
background-color:#fff;
border:3px dotted #000;
}
.circle:after {
content:' ';
display:block;
height:180px;
width:180px;
border-radius:50%;
background-color:#cef;
position:relative;
top:10px;
left:10px;
}
Is there a reason you can't have a second div, like so?
http://jsfiddle.net/gUYFF/1/
.outline {
float:left;
border: dotted 2px black;
width: 220px;
height: 220px;
border-radius: 110px;
box-shadow: 0 0 0 10px white inset;
}
.circle {
background-color: #6abde7;
width: 200px;
height: 200px;
border-radius: 100px;
margin:10px;
}
<div class="outline"><div class="circle"></div></div>
If I use box-sizing: "border-box" for images the images will get smaller, like on hover: Example JsFiddle
Is it possible to do the same effect without the image getting cropped?
Solution #1 Outline property. Try to use outline instead of border with negative outline-offset value equal to outline width:
img:hover {
box-sizing:border-box;
outline: solid 10px #f80;
outline-offset: -10px;
}
http://jsfiddle.net/dfsq/BPRyZ/2/
Also since IE does not understand this property you can leave box-sizing to be used by IE8+.
Solution #2 Using div as wrapper + :after:
<div class="img-wrap">
<img src="http://upload.wikimedia.org/wikipedia/commons/a/af/Bonsai_IMG_6426.jpg" class="img1" />
</div>
CSS:
.img-wrap:after {
border: 0;
}
.img-wrap:hover:after {
content: '';
position: absolute;
top: 0;
left: 0;
bottom: 0;
right: 0;
border: solid 10px #f80;
}
http://jsfiddle.net/dfsq/BPRyZ/7/
The question you need to answer is, do you want the image itself to be 200px, or the entire box to be 200px. There are 4 different ways to code this depending on your answer to the previous question...
If you want the entire box to be 200px wide, then you can use border-box with the following code...
http://jsfiddle.net/BPRyZ/8/
img {
width:200px;
border: transparent 10px solid;
box-sizing:border-box;
}
img:hover{
box-sizing:border-box;
border:solid 10px #f80;
}
If you want the entire box to be 200px wide, then you could also use this code...
img {
width:180px;
border: transparent 10px solid;
}
img:hover{
border:solid 10px #f80;
}
If you want the image itself to be 200px, then you need this code... (this means your total box width is actually 220px)
img {
width:220px;
border: transparent 10px solid;
box-sizing:border-box;
}
img:hover{
box-sizing:border-box;
border:solid 10px #f80;
}
For the above you could also use...
img {
width:200px;
border: transparent 10px solid;
}
img:hover{
border:solid 10px #f80;
}
I updated your jsfiddle
CSS:
img {
width:200px;
border: transparent 10px solid;
}
img:hover{
box-sizing:border-box;
border:solid 10px #f80;
width:220px;
}
I want to create a trapezoid with all corners rounded. I've gotten 2/4 of the way there but can't manage to get the bottom corners look nice. Here is what I have so far: http://jsfiddle.net/w8rHk/2/
Color difference is for illustration only. It will be the same color in the end.
Question: How do I finish this and create a trapezoid with all nicely rounded edged?
1 million points if you can make it scale up and down for screen sizes with out it breaking. That's a ninja level I don't come close to approaching yet.
Question 2: Any way to put a gradient on this bad boy?
Thanks for the help!
Code:
.trapezoid{
vertical-align: middle;
position:relative;
border-bottom: 120px solid blue;
border-left: 200px solid transparent;
border-top-left-radius:30px;
border-top-right-radius:30px;
*border-bottom-right-radius:3px;
height: 0;
width: 150px;}
.trapezoid:after {
content:' ';
left:-14px;
top:-10px;
position:absolute;
background:red;
border-radius:40px 30px 0 0;
width:164px;
height:40px;
display:block;
}
Here's my attempt lol
.trapezoid{
position:relative;
border-bottom: 100px solid blue;
border-right: 12px solid transparent;
border-left: 180px solid transparent;
width: 122px;
}
.trapezoid:before{
content:' ';
left:-184px;
top:98px;
position:absolute;
background:blue;
border-radius:80px 20px 80px 80px;
width:318px;
height:20px;
}
.trapezoid:after {
content:' ';
left:-11px;
top:-7px;
position:absolute;
background:blue;
border-radius:150px 50px 90px 0px;
width:133px;
height:30px;
}
<div style="margin:30px">
<div class="trapezoid">
</div>
</div>
