Search icon in topheader

Hi everyone,

I made a custom searchbar in the header using this code:

add_action( ‘ava_main_header’, ‘enfold_customization_header_widget_area’ );
function enfold_customization_header_widget_area() {
dynamic_sidebar( ‘header’ );
dynamic_sidebar( ‘header-two’ );
}

Is it possible to make a search icon with a search bar coming out on mouseover?

Thanks!
