Question

我正在尝试使滑块上的图像在容器内以全宽显示。我曾尝试将英雄文本div分开，但仍然无法正常工作。我已经坚持了很长时间，意识到它可能有些愚蠢，所以堆栈溢出是我的最后选择。请参见下面的代码和显示方式图片：

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";
}

Answer 1

从您发布的屏幕截图中。问题出在您的CSS上。您已给定background-size：覆盖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。您需要为图像使用以下代码，以占用容器的整个空间。

在CSS中：

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

英雄滑块图像未显示全宽
