Here is what I was thinking for the extending:
```scss
%gcwu-sp-pe-small-mendium-screen-fip-size {
	height: 22px;
	width: 92px;
}

#gcwu-wmms {
	img {
		@extend %gcwu-sp-pe-small-mendium-screen-fip-size;
	}
	object {
		@extend %gcwu-sp-pe-small-mendium-screen-fip-size;
	}
}

#gcwu-wmms-in {
	@extend %gcwu-sp-pe-small-mendium-screen-fip-size;
}
```
