如何创建：引用幻灯片

学习如何使用 CSS 和 JavaScript 创建引用幻灯片。

创建引用幻灯片

第一步 - 添加 HTML：

  
  

    一切反动派都是纸老虎！
    
- 毛泽东
  </div>
  

    改革是中国发展生产力的必由之路。
    
- 邓小平
  </div>
  

    中国共产党人的初心和使命，就是为中国人民谋幸福，为中华民族谋复兴。
    
- 最高领袖
  </div>
  
  ❮
  <a class="next" onclick="plusSlides(1)">❯</a>
</div>
/* Dot/Item symbol/Indicator */
<div class="dot-container">
  <span class="dot" onclick="currentSlide(1)"></span>
  <span class="dot" onclick="currentSlide(2)"></span>
  <span class="dot" onclick="currentSlide(3)"></span>
</div>

Step 2 - Add CSS:

Set the styles for the slides, buttons, dots, etc.:

/* Slideshow container */
.slideshow-container {
  position: relative;
  background: #f1f1f1f1;
}
/* Slides */
.mySlides {
  display: none;
  padding: 80px;
  text-align: center;
}
/* Next & Previous buttons */
.prev, .next {
  cursor: pointer;
  position: absolute;
  top: 50%;
  width: auto;
  margin-top: -30px;
  padding: 16px;
  color: #888;
  font-weight: bold;
  font-size: 20px;
  border-radius: 0 3px 3px 0;
  user-select: none;
}
/* Position the 'next button' to the right */
.next {
  position: absolute;
  right: 0;
  border-radius: 3px 0 0 3px;
}
/* Add a semi-transparent black background color when the mouse hovers */
.prev:hover, .next:hover {
  background-color: rgba(0,0,0,0.8);
  color: white;
}
/* Dot/Item symbol/Indicator container */
.dot-container {
  text-align: center;
  padding: 20px;
  background: #ddd;
}
/* Dot/Item symbol/Indicator */
.dot {
  cursor: pointer;
  height: 15px;
  width: 15px;
  margin: 0 2px;
  background-color: #bbb;
  border-radius: 50%;
  display: inline-block;
  transition: background-color 0.6s ease;
}
/* Add background color for the active dot/circle */
.active, .dot:hover {
  background-color: #717171;
}
/* Add italic style for all quotes */
q {font-style: italic;}
/* Add blue color for the author */
.author {color: cornflowerblue;}

Step 3 - Add JavaScript:

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";
}
