آموزش ساخت گالری اسلاید شو برای سایت

در این مقاله می آموزیم که چطور با استفاده از کد CSS , Html و جاوا اسكريپت Slideshow Gallery ایجاد کنیم.

قدم اول : کد HTML را اضافه کنید.
مثال :

                                 
                


                  
                  

                    
1 / 6
                      
                  

                  

                    
2 / 6
                      
                  

                  

                    
3 / 6
                      
                  

                  

                    
4 / 6
                      
                  

                  

                    
5 / 6
                      
                  

                  

                    
6 / 6
                      
                  

                    
                  ❮
                  ❯

                    
                  

                    

                  

                    
                  

                    

                      
                    
                    

                      
                    
                    

                      
                    
                    

                      
                    
                    

                      
                    
                    

                      
                    
                  
                
                

قدم دوم :   کد CSS را اضافه کنید.
مثال :

                                * {
                  box-sizing: border-box;
                }

                /* Position the image container (needed to position the left and right arrows) */
                .container {
                  position: relative;
                }

                /* Hide the images by default */
                .mySlides {
                  display: none;
                }

                /* Add a pointer when hovering over the thumbnail images */
                .cursor {
                  cursor: pointer;
                }

                /* Next & previous buttons */
                .prev,
                .next {
                  cursor: pointer;
                  position: absolute;
                  top: 40%;
                  width: auto;
                  padding: 16px;
                  margin-top: -50px;
                  color: white;
                  font-weight: bold;
                  font-size: 20px;
                  border-radius: 0 3px 3px 0;
                  user-select: none;
                  -webkit-user-select: none;
                }

                /* 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);
                }

                /* Number text (1/3 etc) */
                .numbertext {
                  color: #f2f2f2;
                  font-size: 12px;
                  padding: 8px 12px;
                  position: absolute;
                  top: 0;
                }

                /* Container for image text */
                .caption-container {
                  text-align: center;
                  background-color: #222;
                  padding: 2px 16px;
                  color: white;
                }

                .row:after {
                  content: "";
                  display: table;
                  clear: both;
                }

                /* Six columns side by side */
                .column {
                  float: left;
                  width: 16.66%;
                }

                /* Add a transparency effect for thumnbail images */
                .demo {
                  opacity: 0.6;
                }

                .active,
                .demo:hover {
                  opacity: 1;
                }
                

قدم سوم :   کد جاوا اسکریپت را اضافه کنید.
مثال :

                               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("demo");
                  var captionText = document.getElementById("caption");
                  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";
                  captionText.innerHTML = dots[slideIndex-1].alt;
                }
