I create a new file, say “sidebar-top”. I make it dynamic
<?php if ( function_exists ( dynamic_sidebar(2) ) ) : ?> Then I go to the function, and register it.
register_sidebar(array( 'name'=>'sidebar-top', 'before_widget' => '<div class="site-description">', 'after_widget' => '</div>' ))
Next, I call this sidebar in need I place?
