Closed 4 years ago.
I try using transform:scale(1.2) to obtain the effect of an appearing circle around the icon. transform I added to the .icon-style:hover::after.
Now this code is commented, please uncomment this code to see what I want to get.
For example I trying doing something like this: click. But scale change position circle.
I read this article, but I don't now how to use transform-origin in my CSS.

First of all, the transform in your hover (.icon-style:hover::after) is overwriting your transform: translate(-50%, -50%);. A way to fix it is to add the translate to the hover too:
.icon-style:hover::after {
opacity: 1;
transform: scale(1.2) translate(-50%, -50%);
}
Then you have to define your transform-origin in .icon-style to top left;
*{
background-color: black;
}
.pos-footer {
position: absolute;
bottom: 20px;
right: 30px;
}
.icon-social {
display: flex;
}
.icon-social-pos {
position: relative;
}
.icon-style {
position: relative;
background-repeat: no-repeat;
background-position: center;
width: 30px;
height: 30px;
background-color: rgba(255, 255, 255, 0.25);
padding: 10px;
border-radius: 50%;
transition: background-color .3s ease-in-out;
}
.icon-style:hover {
background-color: rgba(255, 255, 255, 0.7);
}
.icon-style::after {
content: '';
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
transform-origin: top left;
z-index: 1;
width: 100%;
height: 100%;
border: 5px solid rgba(255, 255, 255, 0.425);
border-radius: 50%;
padding: 7px;
opacity: 0;
transition: all .4s ease-in-out;
}
.icon-style:hover::after {
opacity: 1;
transform: scale(1.2) translate(-50%, -50%);
}
.icon-github {
background-image: url("https://img.icons8.com/windows/30/000000/github.png");
margin-right: 10px;
}
.icon-linkedin {
background-image: url("https://img.icons8.com/ios-glyphs/22/000000/linkedin-2.png");
margin-left: 10px;
}
