Add two more logos to the right and left in the header

Hi everyone. I have read several posts on how to put two logos in the header. I managed but partly….
I use a central logo and menu bar below the logo.
I would like to put two more images on the left and right of the logo in the same div without going out with hover effect.
I have added this function:

add_action( 'ava_main_header', 'enfold_customization_header_widget_area' );
function enfold_customization_header_widget_area() {
	dynamic_sidebar( 'header' );
}

And so I created a widget area called’ header’.
CSS rules do not work well.
To put another logo, do I do the same function and in dynamic_sidebar (‘ another name’)?
Do you also help me with the CSS code to put them on the left and right of the logo in the centre?
Thank you very much.
