To change the styles of an img src SVG with CSS, we set the mask property.
For instance, we write
<div class="logo"></div>
to add a div.
Then we write
.logo {
background-color: red;
-webkit-mask: url(logo.svg) no-repeat center;
mask: url(logo.svg) no-repeat center;
}
to set the mask property to the svg URL to render the svg in the div.
