Chrome 中出现带有 CSS 动画的奇怪白框？

Question

所以我正在尝试使用这个 CSS 滑块，它在 IE 和 firefox 中运行良好，但不适用于 chrome。当第一张图片加载时它看起来很正常但是当第二张图片填满框时我在页面底部得到一个白框。 Image

我在 Pure CCS3 Cycling Slideshow 找到了这段代码，但是当我尝试为我的学校项目自定义它时出现了这个问题。

HTML:

<div id="slider">
                     <div id="mask">
                     <ul>
                     <li id="first" class="firstanimation">
                     <a href="#"> <img src="images/turtleSlider/tur1.jpg" alt="Turtle"/> </a>
                     <div class="tooltip"> <h1>Turtle</h1> </div>
                     </li>

                     <li id="second" class="secondanimation">
                     <a href="#"> <img src="images/turtleSlider/tur2.jpg" alt="Turtle"/> </a>
                     <div class="tooltip"> <h1>My Dad Tomas & A Turtle</h1> </div>
                     </li>

                     <li id="third" class="thirdanimation">
                     <a href="#"> <img src="images/turtleSlider/tur3.jpg" alt="Turtle"/> </a>
                     <div class="tooltip"> <h1>Turtle</h1> </div>
                     </li>

                     <li id="fourth" class="fourthanimation">
                     <a href="#"> <img src="images/turtleSlider/tur4.jpg" alt="Turtle"/> </a>
                     <div class="tooltip"> <h1>Me & A Turtle</h1> </div>
                     </li>

                     <li id="fifth" class="fifthanimation">
                     <a href="#"> <img src="images/turtleSlider/tur5.jpg" alt="Turtle"/> </a>
                     <div class="tooltip"> <h1>Turtle</h1> </div>
                     </li>
                     </ul>

                     </div>
                     <div class="progress-bar"></div>

Answer 1

将以下代码添加到您的 CSS 文件中：

html,
body{
  height: 100%;
}

这个白色矩形在页面上是空的 space，因为文档没有覆盖整个视口。

Answer 2

我明白了。我在底部添加了一些学分作为 <footer>，现在它不再显示了。感谢您的帮助！
