为什么导航栏会以幻灯片形式淡出？

标签： html css

所以我在页面顶部创建了一个粗略的导航栏，在图片幻灯片的顶部（我想），但由于某些原因，当幻灯片改变图像时导航栏的背景颜色渐渐变为透明。如何阻止它执行此操作并将其设置为固定的不透明度？三江源。

嗨
尝试改变它，它应该工作。

<强> HTML 

<li>
<span>
  <img src="ImageHere"></span>
  <div class="slides"><h3>hon·our</h3></div>
</li>

<强> CSS 

.cb-slideshow li .slides h3 {
  font-family: 'BebasNeueRegular', 'Arial Narrow', Arial, sans-serif;
  font-size: 240px;
  z-index: 0;
  position:absolute;
  top:50%;

}
