<p dir="rtl"><a href="/en-US/docs/Web/CSS/Pseudo-elements">شبه عنصر</a> {{ Cssxref("cue::") }} یک عنصر انتخاب شده با نشانههای WebVTT را تطابق میدهد. این <a href="/en-US/docs/Web/CSS/Pseudo-elements">شبه عنصر</a> میتواند برای<a href="/docs/Web/API/WebVTT_API#Styling_WebTT_cues"> آرایش زیرنویس و دیگر موارد</a> محتوای تصویری با VTT tracks مورد استفاده قرار گیرد.</p>
<pre class="brush: css no-line-numbers">::cue {
color: yellow;
font-weight: bold;
}</pre>
<h2 id="Allowable_properties">Allowable properties</h2>
<p>Only a small subset of CSS properties can be used in a rule with <code>::cue</code> in its selector:</p>
<ul>
<li>{{cssxref("color")}}</li>
<li>{{cssxref("opacity")}}</li>
<li>{{cssxref("visibility")}}</li>
<li>{{cssxref("text-decoration")}} and its longhand properties</li>
<li>{{cssxref("text-shadow")}}</li>
<li>{{cssxref("background")}} and its longhand properties</li>
<li>{{cssxref("outline")}} and its longhand properties</li>
<li>{{Cssxref("font")}} and its longhand properties, including {{cssxref("line-height")}}</li>
<li>{{cssxref("white-space")}}</li>
<li>{{cssxref("text-combine-upright")}}</li>
<li>{{cssxref("ruby-position")}}</li>
</ul>
<p>The properties are applied to the entire set of cues as if they were a single unit. The only exception is that <code>background</code> and its shorthand properties apply to each cue individually, to avoid creating boxes and obscuring unexpectedly large areas of the media.</p>
<h2 id="Syntax">Syntax</h2>
<pre class="syntaxbox">{{csssyntax}}</pre>
<h2 id="Example">Example</h2>
<p>The following CSS sets the cue style so that the text is white and the background is a translucent black box.</p>
<pre class="brush: css">::cue {
color: #fff;
background-color: rgba(0, 0, 0, 0.6);
}</pre>
