+<p>El <a href="/en-US/docs/Web/CSS/Pseudo-elements">pseudo-element</a> <a href="/en-US/docs/Web/CSS">CSS</a> <strong><code>::-webkit-progress-bar</code></strong> representa la barra sencere d'un element {{HTMLElement("progress")}}. Normalment només és visible la part no emplenada de la barra, ja que de forma predeterminada es processa a continuació el  pseudo-element {{ cssxref("::-webkit-progress-value") }}. És un fill del pseudo-element {{cssxref("::-webkit-progress-inner-element")}} i el pare del pseudo-element {{cssxref("::-webkit-progress-value")}}.</p>
