我已经创建了这支笔的不透明滑块,我想使用客户证明。我的CSS的推荐信从另一支笔,我可以链接在这里,如果有人愿意。我对编码很陌生,而且是个极端的初学者,所以请原谅我的愚蠢错误。:对于如何改进这一设计,以及如何使它变得更通用,我有什么建议吗?我增加了更多的推荐信(也许是6-8)。我有点困惑的动画属性和他们是如何工作,即延迟和动画的持续时间。我一直在玩这些数字直到它起作用。我计划在我的网站页脚有这个“滑块”。有一件事让我很困扰,那就是它不是中心。我怎么能把滑块对准中心?另外,对于“滑块”的高度,我应该做些什么?我目前的做法并没有什么意义。有点像那种代码。
非常感谢你的建议,我非常感激。:)

除了给您解决方案之外,更重要的是帮助您实际看到元素实际上是以为中心的。
我喜欢在调试CSS代码时使用red,所以尝试将:
.test-slider {
border: 1px solid red;
}现在,您可能会看到.test-slider确实是居中的,但是它的子.test-slide,锚定在其父服务器的左上角,并且由于父服务器的宽度更大,因此它似乎是关闭的。
要解决这个问题,只需设置:
.test-slider {
width: 20.4em; /* Instead of 25em */
}由于.test-slider是不可见的,只是用来包装.test-slide,,所以您并不真正关心它的宽度,所以这个解决方案很好。
另一种方法是设置:
.test-slide {
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}因为您在.test-slide上使用了.test-slide而不是position: relative,,所以您不会遇到任何问题。如果以后要将其更改为position: relative,,只需设置:
.test-slide {
display: inline-block;
margin: 0 auto;
}或者你可以更好地设置:
.test-slider { /* The parent */
text-align: center;
}请查看以下提示,以获得更直观的表示:
