Create a rounded arrow - html

Question

I am trying to make an arrow that looks like this:
However, this is the closest I can get to it:
.button {
margin: 4em 0;
padding: 2em;
width: 15%;
margin: 0 auto;
text-align: center;
background-color: #000000;
color: #ffffff;
display: -moz-box;
display: -ms-flexbox;
display: -webkit-flex;
display: flex;
-moz-flex-flow: row wrap;
-webkit-flex-flow: row wrap;
-ms-flex-flow: row wrap;
flex-flow: row wrap;
webkit-justify-content: center;
justify-content: center;
}
.curved-arrow {
display: inline-block;
border-top: 10px solid #fff;
border-bottom: 10px solid #fff;
border-left: 30px solid #fff;
border-top-right-radius: 100%;
border-bottom-right-radius: 100%;
}
<div class="button">
<div class="curved-arrow"></div>
</div>
Is this even possible? I know I can use images, but my designer made several of these in multiple colors to use throughout the site that I'd rather just use CSS for the shape.
If it's hard to see it's a flat straight line from top to bottom on the left, and curves in to the middle on the right.

Answer 1

SVG
CSS border radius won't let you get the exact output you are looking for easily. I would suggest an inline SVG with the path element with one quadratic bezier command :
svg{width:100px;}
<svg viewbox="0 0 20 8">
<path d="M0 0 Q 30 4 0 8" />
</svg>
Then you can color the arrow with the CSS fill property, see this fiddle (credits to #Nick R for the example posted in the comments)
CSS
You can also use the 2 values for the border-radius property (see MDN for an explanation of how it works) it is simple but it won't let you make the arrow 'point' as sharp as it is in your image :
.curved-arrow {
width:40px; height:25px;
background:#000;
border-top-right-radius:100% 50%;
border-bottom-right-radius:100% 50%;
}
<div class="curved-arrow"></div>

Answer 2

CSS
This requires just a bit of fancy border-radius styling to achieve the shape you want.
.container {
width: 100px;
height: 100px;
background: red;
position: relative;
}
.arrow {
width: 50px;
height: 30px;
position: absolute;
top: 32px;
left: 25%;
border-radius: 0px 100% 100% 0px / 0 50% 50% 0;
background: white;
}
<div class="container">
<div class="arrow"></div>
</div>
If you want it in a single element, you can just use a psuedo element like so.
.arrow {
width: 100px;
height: 100px;
background: red;
position: relative;
}
.arrow:before {
content: '';
width: 50px;
height: 30px;
position: absolute;
top: 32px;
left: 25%;
border-radius: 0px 100% 100% 0px / 0 50% 50% 0;
background: white;
}
<div class="arrow"></div>
SVG
A good alternative would also be SVG to create this shape which also makes it fully responsive.
<svg width="100px" height="100px" viewbox="0 0 20 20" style="background: red;">
<path d="M5,7
Q15,7 15,10
Q15,13 5,13z" fill="white"></path>
</svg>

Answer 3

I think I've made something quite similar, maybe you could change some margins/widths or heights:
#arrow{
display: block;
box-sizing: content-box;
float: none;
width: 130px;
height: 50px;
top: auto;
right: auto;
bottom: auto;
left: auto;
margin: 0;
padding: 0;
overflow: visible;
outline: none;
border: 0 solid rgba(0,0,0,1);
-webkit-border-radius: 50%;
border-radius: 50%;
background: #1abc9c;
box-shadow: none;
text-shadow: none;
margin-left:-65px;
}
#arrow:after {
position:absolute;
left:-65px;
width:65px;
background:transparent;
content:'';
}
It should be an oval, which i hide by an half by using :after ( quite dirty trick )
js fiddle
However, I would recomend you to use CSS sprites, I guess they should fit best your situation, because CSS shapes are not that easy to read for browsers.
Hope it helps! :)

Answer 4

Here's my take on it. Not quite as sharp a point as I'd like, but it's a little bit closer. Edit: second take uses two pseudo-elements to help sharpen the angle.
.button { margin: 4em 0; padding: 2em; width: 15%; margin: 0 auto; text-align: center; background-color: #000000; color: #ffffff; isplay: -moz-box; display: -ms-flexbox; display: -webkit-flex; display: flex; -moz-flex-flow:row wrap; -webkit-flex-flow:row wrap; -ms-flex-flow:row wrap; flex-flow:row wrap; webkit-justify-content: center; justify-content: center; }
.curved-arrow {
position: relative;
display: inline-block;
height: 36px;
width: 56px;
overflow: hidden;
}
.curved-arrow:after {
content: '';
position: absolute;
right: 0;
top: 0;
border-radius: 0 100% 0 0;
height: 50%;
width: 200%;
background: #FFF;
}
.curved-arrow:before {
content: '';
position: absolute;
right: 0;
bottom: 0;
border-radius: 0 0 100% 0;
height: 50%;
width: 200%;
background: #FFF;
}
<div class="button">
<div class="curved-arrow"></div>
</div>

Answer 5

Something like this?
#arrow-base {
width: 120px;
height: 80px;
background: red;
}
#arrow {
width: 0;
height: 0;
border-top: 16px solid transparent;
border-bottom: 16px solid transparent;
border-left: 32px solid white;
display: inline-block;
margin: 24px 44px;
border-radius: 2px;
}
<div id="arrow-base">
<div id="arrow">
<!-- should be empty -->
</div>
</div>
