         </emphasis> is a simple layout component which represents a transparent
      <property>spacer</property>. Thus, the main attributes that define its style are <emphasis>
            <property>"style"</property>
         </emphasis> and <emphasis>
            <property>"styleClass"</property>.</emphasis>

      <para>In addition, the attributes are responsible for the component size: <emphasis>
            <property>"width"</property>
         </emphasis> and <emphasis>
            <property>"height"</property>.</emphasis>
      </para>
      <para>Moreover, to add e.g. some JavaScript effects, events defined on it are used.</para>
