Ability to specify width in terms of percentage

The size parameter only takes in a number array. Is there a way to specify the size in terms of percentage and make it responsive I guess? I couldn't find anything in the documentation regarding this.

Like in the above codesandbox example, how do I make the OrdinalFrame take up the full space of its parent div, which is 70%?
