The CSS code sets the button and text of the previous picture and the next picture.
CSS code:
* {box-sizing:border-box} body {font-family: Verdana,sans-serif;} .mySlides {display:none} /* Slide container */ .slideshow-container { max-width: 1000px; position: relative; margin: auto; } /* Next & Previous button */ .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; } /* Position the "Next" button to the right */ .next { right: 0; border-radius: 3px 0 0 3px; } /* On hover, add a black background color with a little bit see-through */ .prev:hover, .next:hover { background-color: rgba(0,0,0,0.8); } /* Title text */ .text { color: #f2f2f2; font-size: 15px; padding: 8px 12px; position: absolute; bottom: 8px; width: 100%; text-align: center; } /* Numeric text (1/3 etc.) */ .numbertext { color: #f2f2f2; font-size: 12px; padding: 8px 12px; position: absolute; top: 0; } /* mark symbol */ .dot { cursor:pointer; height: 13px; width: 13px; 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 out animation */ .fade { -webkit-animation-name: fade; -webkit-animation-duration: 1.5s; animation-name: fade; animation-duration: 1.5s; } @-webkit-keyframes fade { from {opacity: .4} to {opacity: 1} } @keyframes fade { from {opacity: .4} to {opacity: 1} }
JavaScript code:
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"; }

You can also set the slideshow to automatically play, modify the JavaScript code as follows:
JavaScript code:
var slideIndex = 0; showSlides(); function showSlides() { var i; var slides = document.getElementsByClassName("mySlides"); var dots = document.getElementsByClassName("dot"); for (i = 0; i <slides.length; i++) { slides[i].style.display = "none"; } slideIndex++; if (slideIndex> slides.length) {slideIndex = 1} 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"; setTimeout(showSlides, 2000); // switching time is 2 seconds }
