Thanks for your help.I has builded the child theme of bp child with 2 folders as the instruction.
And add the codes to style.css

/*
Theme Name: BP Child
Tags: buddypress
Template: bp-default
*/

And add the code to functional.php

if ( !function_exists( ‘bp_dtheme_enqueue_styles’ ) ) :
function bp_dtheme_enqueue_styles() {

// You should bump this version when changes are made to bust cache
$version = ‘20111109’;

// Register stylesheet of bp-dusk child theme
wp_register_style( ‘bp-dusk’, get_stylesheet_directory_uri() . ‘/style.css’, array(), $version );

// Enqueue stylesheet of bp-dusk chid theme
wp_enqueue_style( ‘bp-dusk’ );
}
add_action( ‘wp_enqueue_scripts’, ‘bp_dtheme_enqueue_styles’ );

Then i appended the changing css codes to child theme style.css
.content-wrapper-inner {
background-color: black;
}
BUT nothing has changed.

And
