html - 为什么我的导航栏会随着幻灯片放映而变淡？

Question

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(我认为)，但由于某种原因，随着幻灯片更改图像，导航栏的背景颜色逐渐变为透明。我如何阻止它这样做，并将其设置为固定的不透明度？谢谢。

你好
尝试改变它，它应该可以工作。

HTML

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

CSS

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

}
