Question

我使用过w3school引导程序主题，但是图像上应该显示的文字并没有显示出来。我确实改变了图像，所以可能有一个问题，谢谢你的帮助。

当我运行我的网页时，我看不到滑块上的文字，并尝试了一堆不同的结果。

这是我的代码，这里很新，所以不确定我是否正确地执行代码块事情向您显示。

Answer 1

当我运行你的代码时，我可以看到你有一个css样式，设置为none。

.carousel-caption {
  display: none;
}

如果您对此发表评论/ * display：none; * /或将其更改为

.carousel-caption {
  display: block;
}

这应该显示图像上方的文字。

Answer 2

从css中删除以下代码：

.carousel-caption {
  display: none;
  /* Hide the carousel text when the screen is less than 600 pixels wide */
}

上述文字应放在媒体查询中，以隐藏屏幕尺寸小于600像素的文字。

如果你想达到同样的目的，你可以做的就是附上以下代码：

@media only screen and (max-width: 600px) {
    .carousel-caption {
      display: none;
      /* Hide the carousel text when the screen is less than 600 pixels wide */
    } 
}

轮播文字没有显示图片？
