Override iframe fixed size iz shortcode for wordpress plugin

Question

I am working with wordpress plugin for fb feed. It gives a short code where you can set width and height. But only in pixels. Is there a chance to set it in % (width and height 100%)?

Here is a code:

[efb_likebox fanpage_url="SPIBiH" box_width="336" box_height="487" locale="en_US" responsive="1" show_faces="1" show_stream="1" hide_cover="0" small_header="0" hide_cta="0" animate_effect="fadeIn" ]

This creates HTML with iframe. I don't know how to override this sizes in css.

You can't target the iframe with CSS oridinarily, but you can add some javascript that will add classes to your iframe that can be targeted.
