how to add css to Edge

I'm looking for a site that will show the different ways one can add CSS to an object in Edge.

Found this code on one site...

sym.$(manOne).css({"width":"275", "height":"280"});

Found this code on another...

sym.$(manOne).css({"width", 275});

Commas...no commas...add a colon...no colon...

What is the standard way for expressing CSS code in the Actions panel. Specifically, I'm looking to scale an object's x & y, but would love to know what the common language for adding CSS to Edge looks like.

Thanks,
