Planyo integration in Enfold, interferring css?

Building a new site for a company hiring out boats. They want to use Planyo booking system – http://planyo.com.
I´ve done my first try to integrate one of Planyos widgets (nervous what will happen with all the others).
I´ve placed the code for the ”Availability search box” in a code block (first page http://new.gotakanacharter.se ) and in a text widget ( http://new.gotakanalcharter.se/planera-din-resa/ ).
In the first case the calender doesn´t appear, in the text widget case there are some ugly text boxes witch also appears on a booking page:

The code that I have placed both in the code box and in the widget i as below (yes, it´s possible to change the css i planyos system, but I don´t know how….)
