Question

当其中一个元素改变其大小时会发生这种情况。一个例子是幻灯片。一张图片具有特定尺寸，第二张图片更高。幻灯片下方有一个文本，当您从一张图片切换到另一张图片时，较高的图片会覆盖文本，反之亦然。

如何解决这个问题？

var slideIndex = [1,1];
var slideId = ["mySlides1", "mySlides2"]
showSlides(1, 0);
showSlides(1, 1);

function plusSlides(n, no) {
  showSlides(slideIndex[no] += n, no);
}

function showSlides(n, no) {
  var i;
  var x = document.getElementsByClassName(slideId[no]);
  if (n > x.length) {slideIndex[no] = 1}    
  if (n < 1) {slideIndex[no] = x.length}
  for (i = 0; i < x.length; i++) {
     x[i].style.display = "none";  
  }
  x[slideIndex[no]-1].style.display = "block";  
}

* {box-sizing: border-box}
    .mySlides1 .mySlides2 {display: none;}
    img {vertical-align: middle;}
    
    /* Slideshow container */
    .slideshow-container {
      max-width: 1000px;
      position: relative;
      margin: auto;
    }
    
    /* Next & previous buttons */
    .prev, .next {

      top: 50%;

Answer 1

如果您只想防止文本与图像重叠，请在 CSS 中尝试：

.text {
  font-family: "Raleway", sans-serif;
  position: relative;
  text-align: center;
  font-size: 4vw;
  width: 100%;
}

选项 2（未测试）您可以像这样将位置应用于 .text：

.text {
    font-family: "Raleway", sans-serif;
    position: absolute;
    bottom: 0;
    text-align: center;
    font-size: 4vw;
    width: 100%;
}

.slideshow-container {
  max-width: 1000px;
  position: relative;
  margin: auto;
  padding-bottom: 100px; /* adjust for your text size */
}
