I have a testimonials box that I would like to add a triangle to.
.arrow {
float: left;
margin-left: 25px;
margin-top: 20px;
width: 0;
height: 0;
border-top: 20px solid #eee;
border-left: 0px solid transparent;
border-right: 25px solid transparent;
}
The problem is the triangle ends up being solid, as opposed to white with a gray border. Below is a screenshot of how the CSS currently displays. Thanks in advance for the time and help.
You can create two triangles, one that overlaps the other, to create this bordered effect. You can do this with the ::before and ::after pseudo-elements so that you don't even have any superfluous HTML.
http://jsfiddle.net/7K2c4/
.mybox {
position: relative;
border: 1px solid #ccc;
}
.mybox:before,
.mybox:after { position: absolute;
left: 20px;
bottom: -19px;
display: block;
width: 0;
height: 0;
border-width: 0 25px 20px;
border-style: solid;
border-color: transparent;
border-left-color: #fff;
content: ' ';
}
.mybox:before { left: 19px;
bottom: -21px;
border-left-color: #ccc; }
You can place another triangle over it, smaller with the same color of the box background. You don't even need to create another HTML element, just use a pseudo-element selector.

I'm trying to absolute position an arrow relative to a button that toggles a filter box using :before pseudo-element.
I think I can't position relative to the filter box because its width is related to other div and I need the triangle to be aligned with the outside button.
Problem: when button is focused, the outline is present both in button and its :before, aka my triangle. I'm searching for a solution that outlines the button, but not its :before.
What I've already tried: set the rule outline: none; in the :before selector. Didn't worked.
What I've achieved:
My code, simplified for question purpose:
/* Toggle control isn't necessary for the purpose of the question */
.button-filter {
background-color: #333;
color: $click-white;
position: relative;
border: none;
color: #fff;
padding: 1em;
}
.button-filter:before {
content: "";
position: absolute;
display: block;
width: 0;
height: 0;
left: calc(50% - 15px);
bottom: -20px;
border-bottom: 15px solid #333;
border-left: 15px solid transparent;
border-right: 15px solid transparent;
}
<button class="button-filter" autofocus>Filter</button>
You can change the outline with a box-shadowto avoid this effect:
.button-filter {
background-color: #333;
position: relative;
border: none;
color: #fff;
padding: 1em;
}
.button-filter:before {
content: "";
position: absolute;
display: block;
width: 0;
height: 0;
left: calc(50% - 15px);
bottom: -20px;
border-bottom: 15px solid #333;
border-left: 15px solid transparent;
border-right: 15px solid transparent;
}
.button-filter:focus {
outline:none;
box-shadow:0 0 5px blue;
}
<button class="button-filter" autofocus>Filter</button>
Asuming that the pseudo will used to create an arrow next to another element, you don't really need it to be a triangle, it can be a rotated square. The lower part of it will be hidden by the other div.
If this is the case, the you can set the pseudo as a small square located inside the button. I set it red to show where it is, but in production you can set background transparent, or set z-index : -1;
And then set a shadow, located where you want the triangle to be. Since this is a shadow, not a real element, the outline won't be applied to it. (Note: the element is rotated, so the shadow coordinates are tricky)
/* Toggle control isn't necessary for the purpose of the question */
.button-filter {
background-color: #333;
color: $click-white;
position: relative;
border: none;
color: #fff;
padding: 1em;
}
.button-filter:after {
content: "";
position: absolute;
display: block;
width: 5px;
height: 5px;
left: 50%;
bottom: 10px;
transform: rotate(45deg);
background-color: red;
box-shadow: 40px 40px 0px 10px black;
}
<button class="button-filter" autofocus>Filter</button>
Hi I am trying to create a custom arrow in CSS that looks like the image below.
Ideally I want to create this by overlaying two shapes a triangle and a rectangle (maybe using CSS :after and :before) but I'm not too savvy when it comes to CSS so I have been struggling.I started by just using borders but doesn't look like it is going to work
So far I just have:
.arrow {
width: 0;
height: 0;
border-top: 60px solid transparent;
border-bottom: 60px solid transparent;
border-left: 60px solid #ccc;
}
<div class="arrow"></div>
Not too hard to make using the :before pseudo element and some transforms:
.container {
padding: 100px;
}
.arrow {
display: inline-block;
height: 150px;
background: #000;
width: 75px;
}
.arrow:before {
content: "";
border-top: 100px solid #000;
border-left: 100px solid transparent;
border-right: 100px solid transparent;
border-bottom: 100px solid transparent;
transform: rotateZ(180deg) translateY(100%) translateX(31%);
position: relative;
display: inline-block;
}
<div class="container">
<div class="arrow"></div>
</div>
Here's another option.
.arrow{
width: 0;
height: 0;
border-top: 60px solid transparent;
border-bottom: 60px solid transparent;
border-left: 60px solid #ccc;
position: relative;
margin: 0 0 0 100px;
}
.arrow::before{
content: "";
height:50px;
width:80px;
background: #ccc;
position: absolute;
top: 0;
margin: -100%;
display: block;
transform: translateX(-160%) translateY(-50%);
}
<div class="arrow"></div>
Create one rectangle and then add triangle on top with :before pseudo-element and that is it.
.arrow {
width: 36px;
height: 50px;
background: #3F3F3F;
position: relative;
margin: 60px;
}
.arrow:before {
content: '';
border-style: solid;
border-width: 0 40px 40px 40px;
border-color: transparent transparent #3F3F3F transparent;
position: absolute;
top: 0;
left: 50%;
transform: translate(-50%, -100%);
}
<div class="arrow"></div>
To explain and demonstrate:
A CSS arrow is created by coloring 1 border side, and then moving the other 3 sides in towards the middle of the shape as transparent so they don't show but cut the remaining colored side into a triangle. The shorthand for this is TOP RIGHT BOTTOM LEFT. So to make a triangle pointing upwards you use the third property or bottom.
Using pseudo elements (incase you want the arrow added to another element) you need content:'' to "create" the pseudo element. I've set them as display: block so that they are in the flow and interact with eachother (rather than being laid on top of one another).
By giving the rectangle position: relative you can then use left: 30px (half of the triangle width) to position it in the middle of the triangle.
.arrowWrapper:before {
content: '';
display: block;
width: 0;
height: 0;
border-style: solid;
border-width: 0 60px 60px 60px;
border-color: transparent transparent black transparent;
/* border-color: TOP RIGHT BOTTOM LEFT; */
}
.arrowWrapper:after {
content: '';
position: relative;
display: block;
width: 60px;
height: 60px;
background: black;
left: 30px;
}
<div class="arrowWrapper"></div>
Lifted and modified from http://www.cssportal.com/css3-shapes/:
#eq-triangle {
width: 0;
height: 0;
border-bottom: 104px solid blue;
border-left: 60px solid transparent;
border-right: 60px solid transparent;
}
#rectangle {
width: 40px;
height: 80px;
background: blue;
margin-left: 40px;
}
<div id="eq-triangle"></div>
<div id="rectangle"></div>
How would I achieve the following as seen in the image below, in the best way as possible? I want a thick top border, but as it goes down I want the sides to become thinner and just "mend" (if that's right expression) into the black block.
This is my CSS code for the black block:
.containerMain {
background: #000;
padding: 15px;
border-radius: 5px;
width: 250px;
}
You can use the after pseudo-element to position an upside-down trapezoid behind your element.
Look here for a trapezoid shape example.
body { padding: 30px; }
.containerMain {
background: black;
padding: 15px;
border-radius: 5px;
width: 250px;
height: 250px;
position: relative;
}
.containerMain:after {
content: '';
border-radius: inherit;
margin: -20px;
margin-top: -25px;
width: 100%;
height: 50%;
position: absolute;
z-index: -1;
/* upside-down red trapezoid props */
border-top-width: 150px;
border-top-style: solid;
border-top-color: red;
border-left: 5px solid transparent;
border-right: 5px solid transparent;
}
<div class="containerMain"></div>
So I'm drawing elements in CSS, using this tutorial as a guide. I need some help with borders, though. For instance, here's my code for a curved trapezoid:
.foobar {
height: 0px;
width: 140px;
position: relative;
border-bottom: 200px solid red;
border-left: 30px solid transparent;
border-right: 30px solid transparent;
border-bottom-left-radius: 150px 70px;
border-bottom-right-radius: 100px 25px;
}
The problem: I want to draw a 1px line border around the foobar element, but I'm already using the border properties to draw the element in the first place.
Is there an easy way to do this? My sense is that I'll have to create a shadow element that is the same shape as -- but slightly larger than -- the foobar element.
Thanks in advance!
You can position a :pseudo element behind with slightly adjusted dimensions.
.foobar, .foobar:before {
height: 0px;
width: 140px;
position: relative;
border-bottom: 200px solid red;
border-left: 30px solid transparent;
border-right: 30px solid transparent;
border-bottom-left-radius: 150px 70px;
border-bottom-right-radius: 100px 25px;
}
.foobar:before {
content: "";
display:block;
position: absolute;
left: -31px;
top: -1px;
width: 142px;
z-index: -1;
border-bottom: 202px solid black;
/* add these lines if you're a pixel perfectionist */
border-bottom-left-radius: 150px 71px;
border-bottom-right-radius: 100px 26px;
}

You can use a pseudo element drawn behind with same rules with a small increase of scale.
.foobar, .foobar:before {
height: 0px;
width: 140px;
position: relative;
border-bottom: 200px solid red;
border-left: 30px solid transparent;
border-right: 30px solid transparent;
border-bottom-left-radius: 150px 70px;
border-bottom-right-radius: 100px 25px;
position:relative;
}
.foobar:before {
content:'';
position:absolute;
display:block;
z-index:-1;
top:0;
left:-30px;
width: 140px;
-webkit-transform-origin:center;
-webkit-transform:scale(1.03);/* adapt here the width of your fake border */
transform-origin:center;
transform:scale(1.03);
border-bottom: 200px solid black; /* color of fake border */
}

You can even play with both pseudo-element and still add some shadows: http://codepen.io/gc-nomade/pen/axmsc
I want to make a CSS only speech bubble. So far, I have this...
Example
CSS
div {
position: relative;
background: #fff;
padding: 10px;
font-size: 12px;
text-align: center;
-webkit-border-radius: 20px;
-moz-border-radius: 20px;
border-radius: 20px;
}
div:after {
content: "";
display: block;
width: 0;
height: 0;
position: absolute;
left: 50%;
bottom: -60px;
margin-left: -15px;
border-width: 30px 20px 30px 20px;
border-style: solid;
border-color: #fff transparent transparent transparent;
}
jsFiddle.
...which is almost exactly what I want. However, I want a light border around the whole thing.
Obviously, on the main portion, that is simple as adding border: 1px solid #333 to the div.
However, as the tail of the bubble is a border hack, I can't user a border with it.
I tried setting a box shadow of 0 0 1px #333 but browsers apply the border to the rectangular shape of the element (which I guess is what they should do).
jsFiddle.
My next thoughts were finding a Unicode character that looks like a bubble tail and absolutely positioning it there, with text-shadow for the border and using z-index of the main bubble to hide the top shadow of the text.
What Unicode character would be suitable for this? Should I do something different? Do I need to resort to an image?
I only have to support Mobile Safari. :)
<div>Hello Stack Overflow!<span></span></div>
div span:after {
content: "";
display: block;
width: 0;
height: 0;
position: absolute;
left: 50%;
bottom: -51px;
margin-left: -15px;
border-width: 20px 20px 30px 20px;
border-style: solid;
border-color: #000 transparent transparent transparent;
}

For the Unicode character approach you suggested, the most appropriate would be ▼ U+25BC BLACK DOWN-POINTING TRIANGLE. I don't know whether iOS has glyphs for it.
Here is a similar solution:
http://jsfiddle.net/JyPBD/2/
<div>Hello Stack Overflow!<span></span></div>
body {
background: #ccc;
}
div {
position: relative;
background: #fff;
padding: 10px;
font-size: 12px;
text-align: center;
-webkit-border-radius: 20px;
-moz-border-radius: 20px;
border-radius: 20px;
border: 1px solid #333;
}
div:after {
content: "";
display: block;
width: 0;
height: 0;
position: absolute;
left: 50%;
bottom: -60px;
margin-left: -16px;
border-width: 30px 20px 30px 20px;
border-style: solid;
border-color: green transparent transparent transparent;
}
div span
{
border-color: #FF0000 transparent transparent;
border-style: solid;
border-width: 25px 15px;
bottom: -51px;
margin-left: -65px;
position: absolute;
z-index: 10;
}
You could use the filter property with box-shadow() to do it...
-webkit-filter: drop-shadow(1px 1px 1px #111) drop-shadow(-1px -1px 1px #111);
jsFiddle.
