Thanks ray,
I tried both

<?php if ( bp_get_group_id(1) ) { echo ‘yes’; } ?>

and

<?php global $bp; if ( $bp->groups->current_group->id == 1 ) { echo ‘yes’; } ?>

but they are not working…

Oops, HTML tags are disappeared! I wanted to say

if( [group ID that displayed user is joining] == 1){
echo ‘<div class="classA">‘;
} else {
echo ‘<div class="classB">’;
}
