Squircle template rounding [duplicate] - html

Question

I've been banging my head against the wall trying to figure out how to use The Code Player's CSS3 Squircles example to create an iOS-7-style app icon on my website (testing in the Safari browser). The example uses pseudo tags to clip the background color, whereas I need to crop around an <img>. In case you're not familiar, a squircle is like a rounded-rect, but with the sides rounding beyond the corner radius, like so:
.icons img {
width: 100px;
height: 100px;
border-radius: 24%;
}
.icons a {
text-decoration: none;
display: inline-block;
position: relative;
}
/*Now we will create fish-eye shapes using pseudo elements and clip them to add a curve to the sides of the icons*/
.icons a:before, .icons a:after {
content: '';
position: absolute; left: 0; top: 0;
width: 100%; height: 100%;
background: inherit;
border-radius: 100%; /*circle*/
/*time to transform the circle into fish-eye shape. iOS7 style now.*/
-webkit-transform: scaleX(2) scaleY(1.05);
transform: scaleX(2) scaleY(1.05);
/*clipping the left and right sides - 17px from the left and right*/
clip: rect(0, 66px, 100px, 34px);
/*pushing it behind the icon*/
z-index: -1;
}
/*duplicating the :before element and rotating it 90deg and swapping the X/Y transforms*/
.icons a:after {
-webkit-transform: scaleY(2) scaleX(1.05) rotate(90deg);
}
<div class="icons">
<img src="http://lorempixel.com/256/256/abstract/2/" />
</div>

Answer 1

The easiest solution might be to create the image with a transparent background until some of the following features are implemented.
If you can add the image via CSS then you could just add height, width, background-image and background-size to the link (.icons a).
Note: This might not be the desired effect as it is complemented by a background colour.
.icons a {
height: 100px;
width: 100px;
background-image: url(https://picsum.photos/256/);
background-size: cover;
text-decoration: none;
color: white;
display: inline-block;
margin: 20px;
border-radius: 24px;
position: relative;
}
.icons a:before,
.icons a:after {
content: '';
position: absolute;
left: 0;
top: 0;
width: 100%;
height: 100%;
background: inherit;
border-radius: 100%;
-webkit-transform: scaleX(2) scaleY(1.05);
transform: scaleX(2) scaleY(1.05);
clip: rect(0, 66px, 100px, 34px);
z-index: -1;
}
.icons a:after {
-webkit-transform: scaleY(2) scaleX(1.05) rotate(90deg);
transform: scaleY(2) scaleX(1.05) rotate(90deg);
}
<div class="icons">
</div>
If this is not the case you could add size and border radius to the image. In this case the the pseudo rounded borders are filled by a background colour on the '.icon a' element.
Note: This might not be the desired effect as it is complemented by a background colour.
.icons a {
height: 100px;
width: 100px;
background: red;
text-decoration: none;
color: white;
display: inline-block;
margin: 20px;
border-radius: 24px;
position: relative;
}
.icons img{
height: 100px;
width: 100px;
border-radius: 24px;
}
.icons a:before, .icons a:after {
content: '';
overflow: hidden;
position: absolute; left: 0; top: 0;
width: 100%; height: 100%;
background: inherit;
border-radius: 100%;
-webkit-transform: scaleX(2) scaleY(1.05);
transform: scaleX(2) scaleY(1.05);
clip: rect(0, 66px, 100px, 34px);
z-index: -1;
}
.icons a:after {
-webkit-transform: scaleY(2) scaleX(1.05) rotate(90deg);
transform: scaleY(2) scaleX(1.05) rotate(90deg);
}
<div class="icons">
<a href="#">
<img src="https://picsum.photos/256/">
</a>
</div>
SVG Solution 1:
Use a cliping-path using an svg but this is not yet supported by webkit (sticks the clipped image at the top left of the screen). See this link for more info: https://css-tricks.com/clipping-masking-css/#comment-1587234
#squircle{
-webkit-clip-path: url(#svg-shape);
-moz-clip-path: url(#svg-shape);
-o-clip-path: url(#svg-shape);
-ms-clip-path: url(#svg-shape);
clip-path: url(#svg-shape);
}
<img src="https://picsum.photos/400/" id="squircle">
<svg height="0" width="0" version="1.1"
xmlns="http://www.w3.org/2000/svg">
<defs>
<clipPath id="svg-shape">
<path d="M100,200c43.8,0,68.2,0,84.1-15.9C200,168.2,200,143.8,200,100s0-68.2-15.9-84.1C168.2,0,143.8,0,100,0S31.8,0,15.9,15.9C0,31.8,0,56.2,0,100s0,68.2,15.9,84.1C31.8,200,56.2,200,100,200z" />
</clipPath>
</defs>
</svg>
SVG Solution 2:
Use a pattern to add the image as a background image.
svg.iOS-svg {
height: 100px;
width: 100px;
}
<svg class="iOS-svg" viewBox="0 0 200 200">
<defs>
<pattern id="squircle" patternUnits="userSpaceOnUse" width="200" height="200">
<image xlink:href="https://picsum.photos/256/" x="0" y="0" width="200" height="200" />
</pattern>
</defs>
<path d="M100,200c43.8,0,68.2,0,84.1-15.9C200,168.2,200,143.8,200,100s0-68.2-15.9-84.1C168.2,0,143.8,0,100,0S31.8,0,15.9,15.9C0,31.8,0,56.2,0,100s0,68.2,15.9,84.1C31.8,200,56.2,200,100,200z" fill="url(#squircle)" />

Answer 3

A squircle is not border-radius or round corners, and you must draw the path by yourself.
