<!DOCTYPE html>
<html>
<body>
<style>
.someClass {
fill:gray;
}
</style>
<svg width="400" height="110">
<rect class="someClass" width="100" height="100"/>
</svg>
<svg width="400" height="110">
<rect class="someClass" width="100" height="100"/>
</svg>
<svg width="400" height="110">
<rect class="a" width="100" height="100"/>
</svg>
</body>
