最佳答案

您可以覆盖.carousel-caption CSS规则来调整元素的大小，以使其清晰可见。

@media screen and (max-width: 768px)
     {    .carousel-caption {
          bottom: 50px !important;
          }
          .carousel-caption h1 {
          font-size : 20px !important;
          }
     }

对于最大宽度为768px的设备，上述CSS会将h1元素的字体大小更改为20px。 CSS类.carousel-caption的位置是绝对的，因此，如果不合适的话，请将bottom增大到更高。
