    <title>Look-and-Feel Customization</title>

    <para>For skinnability implementation, the components use a style class redefinition method.
      Default style classes are mapped on skin parameters.</para>

    <para>To redefine appearance of all <emphasis role="bold">
        <property>&lt;rich:messages&gt;</property>
      </emphasis> components, you can define the properties of the predefined style classes in the
      common CSS style sheet used on a page (there are no skin parameters and predefined values by
      default to make it compatible with the standard message component). </para>

    <para>In order to redefine styles for all <emphasis role="bold">
      <property>&lt;rich:messages&gt;</property>
    </emphasis> components on a page using CSS, it&apos;s enough to create classes with the

    <para>To change styles of particular <emphasis role="bold">
      <property>&lt;rich:messages&gt;</property>
    </emphasis> components, define your own style classes in the corresponding <emphasis
