响应文字定位？

Question

我将Bootstrap旋转木马滑块与文本一起使用（旋转木马标题）。它在所有设备上都响应，但是文本始终居中并位于屏幕底部。我知道如何将文本放置在我想要的任何地方。

但是，如果我更改位置，则无法在其他设备上正确显示。我只想将文本放在屏幕的左侧和中间，并希望在调整视口大小时将其保留在屏幕上。

Answer 1

我不确定您是否要将文本水平或垂直居中。所以两个答案： 水平 您要居中的.carousel-caption元素的宽度为px，以百分比为单位。

您只能使用百分比值：

.carousel-caption {
    width: 70%;
    left: 15%;
}

或使其全角显示，因为其中包含的所有文本均居中：

.carousel-caption {
   width: 100%;
   left: 0px;
   right:0px;
}

垂直

.carousel-caption {
    top: 50%;
    bottom: auto;
    transform: translateY(-50%);
}

Answer 2

以最小的变化；将您的“ .carousel-caption”样式块替换为以下内容：

.carousel-caption {
  top: 0 !important;
  left: 0 !important;
  width: 100%;
  max-width: 100vw;
  padding: 0 15%;
}

并添加“我只想将文本留在屏幕中间”

.carousel-caption .lead {
  text-align: left;
  position: absolute;
  top: 45vh;
}
