Contact Form 7 style

Simply add styles for the fields to your theme’s stylesheet.

could you please advise with an example?

#your-sidebar .wpcf7 input.wpcf7-text,
#your-sidebar .wpcf7 textarea {
	width: 20px;
}

like this. Obviously you need to change the #your-sidebar to the real id of your sidebar.

Thanks a lot Takayuki Miyoshi! This helps a lot!!!
Peace to you!!
