Answer 1

您假设变换框是填充框，但默认情况下不是，它是 View 框。你可以用 transform-box 修复它

a {
    width: 40px;
    height: 40px;
    width: 40px;
    font-size: 1.5rem;
    padding: 1px;
    overflow: hidden;
    border: 1px solid black;  
}

a:hover path {
    -webkit-transform: rotate(360deg);
    -moz-transform: rotate(360deg);
    -ms-transform: rotate(360deg);
    -o-transform: rotate(360deg);
    transform: rotate(360deg);    
}

a path {
    transition: all .5s ease-in-out;
    transform-origin: center center;
    transform-box: fill-box;
}
