          <p>Holographic projection creates 3D-like visual effects using layered transparency, gradients, and light effects.</p>

        </div>
        <div class="faq-answer">
          <p>Effects use CSS gradients, box-shadows, and pseudo-elements to simulate light projection and depth.</p>

          <p>While not true 3D, the visual effects create an illusion of depth using advanced CSS techniques.</p>
