响应式文本定位？

Question

我使用 Bootstrap 带文本的轮播滑块（轮播字幕）。它在所有设备上都有响应，但文本始终居中并位于屏幕底部。我知道如何将文本放在我想要的位置。

但是如果我改变位置，它就不能在其他设备上正确显示。我只想将文本定位在屏幕的左侧和中间，并且我希望它在我调整视口大小时保持在那里。

.carousel-caption {
  top: 35%;
  width:500px;
  left: 220px;
  bottom: auto;
}

.carousel-item {
  height: 100vh;

  width: 1em;
  height: 1em;

}

.services-icon {
  margin-bottom: 20px;
  font-size: 30px;
}

Answer 1

我不确定您是要水平居中还是垂直居中。所以两个答案：横向您想要居中的元素 .carousel-caption 具有 px 宽度和百分比边距。

您可以只使用百分比值：

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

或者让它全宽，因为所有包含的文本都居中：

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

垂直

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

Answer 2

对于最小的变化；用以下内容替换您的“.carousel-caption”样式块：

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

然后添加 "I just want to put text left in the middle of the screen":

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