How to squircle an app icon image with just CSS
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">
<a href="#"></a>
</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>
</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

width: 100px;
}<svg class="iOS-svg" viewBox="0 0 200 200">
