title: Can't implement the W3Schools slideshow in Bootstrap?
body: <p>I'm trying to edit my Bootstrap and I want to add more stuff then what it already has but it isn't working.</p>
  
  <p>I tried to add a slideshow, but it is completely white, only the arrows to change the image are blue.</p>
  
  <p>I know part of it is working because when I click to change the image, the dimensions of the page change (I only have 1 photo, the others 2 links are for photos that don't exist).</p>
  
  <p>I copied the W3Schools code and pasted it in the bootstrap page, is something in the bootstrap file, putting everything white?</p>
  
  <p>Here is my code:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>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 &gt; slides.length) {
      slideIndex = 1
    }
    if (n &lt; 1) {
      slideIndex = slides.length
    }
    for (i = 0; i &lt; slides.length; i++) {
      slides[i].style.display = "none";
    }
    for (i = 0; i &lt; dots.length; i++) {
      dots[i].className = dots[i].className.replace(" active", "");
    }
    slides[slideIndex - 1].style.display = "block";
    dots[slideIndex - 1].className += " active";
