Question

我的图片不会显示在我的幻灯片上。
我直接从w3school复制并粘贴了html和css的幻灯片代码，它适用于我之前的项目，但它不能用于我当前的项目。我不认为，我在我的HTML中做错了，因为在我编写css之前，图像就在那里。此外，如果我删除代码显示：无，图像会再次出现，但它们遍布整个地方。

请帮助这位可怜的学生在tmr中提交作业！

以下是我对html5和css的编码

    .slide {
    width: 30%;
    margin: auto;

}



 .mySlides {
    display: none;
}



  .prev, .next {
  cursor: pointer;
  position: absolute;
  top: 50%;
  width: auto;
  margin-top: -22px;
  padding: 16px;
  color: white;
  font-weight: bold;
  font-size: 18px;
  transition: 0.6s ease;
  border-radius: 0 3px 3px 0;
}

.next {
  right: 0;
  border-radius: 3px 0 0 3px;
}


.prev:hover, .next:hover {
  background-color: #ec7979;
}



.text {
  color: #f2f2f2;
  font-size: 15px;
  padding: 8px 12px;
  position: absolute;
  bottom: 8px;
  width: 100%;
  text-align: center;
}



.numbertext {
  color: #f2f2f2;
  font-size: 12px;
  padding: 8px 12px;
  position: absolute;

}



.dot {

  width: 15px;
  margin: 0 2px;
  background-color: #bbb;
  border-radius: 50%;
  display: inline-block;
  transition: background-color 0.6s ease;
}

.active, .dot:hover {
  background-color: #717171;
}



.fade {
  -webkit-animation-name: fade;
  -webkit-animation-duration: 1.5s;

  animation-duration: 1.5s;

@-webkit-keyframes fade {

Can you share w3 school slider link where you got code for slider.


<script>
var slideIndex = 1;
showSlides(slideIndex);

function plusSlides(n) {
  showSlides(slideIndex += n);
}

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";
}
</script>
