我试图让 slider 上的图像在容器内全宽显示。我试过分离英雄文本 div，但它仍然不起作用。我多年来一直坚持这个，并意识到它可能是愚蠢的，所以堆栈溢出是我最后的选择。请参阅下面的代码和显示方式的图像:

Display Image 

var slideIndex = 1;
showSlides(slideIndex);

// Next/previous controls
function plusSlides(n) {
  showSlides(slideIndex += n);
}

// Thumbnail image controls
function currentSlide(n) {
  showSlides(slideIndex = n);
}

function showSlides(n) {
  var i;
  var slides = document.getElementsByClassName("mySlides");
  var dots = document.getElementsByClassName("dot");
  if (n > slides.length) {slideIndex = 1}
  if (n < 1) {slideIndex = slides.length}
  for (i = 0; i < slides.length; i++) {
      slides[i].style.display = "none";
  }
  for (i = 0; i < dots.length; i++) {
      dots[i].className = dots[i].className.replace(" active", "");
  }
  slides[slideIndex-1].style.display = "block";
  dots[slideIndex-1].className += " active";
}

最佳答案

根据您发布的屏幕截图。问题出在你的CSS上。您已将 background-size: 覆盖到容器而不是内部图像。这就是为什么它不会占用整个空间的原因。您需要以下代码让您的图像占用容器的整个空间。

在 CSS 中:

.mySlides { background-size: cover ; height : 500px; }
