How to resize the ClipPath area of SVG?
You can apply the SVG as a mask and easily adjust its size and position (like you can with background-image). Simply make sure you set the correct value for the viewbox:
.img-container {
width: 300px;
height: 300px;
background-color: lightgreen;
margin:5px;
}
.clipped-img {
width:100%;
height:100%;
display:block;
object-fit:cover;
