روی یکی از تصاویر زیر کلیک کنید تا Lightbox باز شود :

مثال زیر ترکیبی از کدهای Modal و Slideshow را برای ایجاد Lightbox نشان میدهد :

قدم اول : کد HTML را اضافه کنید.
مثال :

                                
                

                  

                    
                  
                  

                    
                  
                  

                    
                  
                  

                    
                  
                

                                    
                

                  ×
                  


                    

                      
1 / 4
                      
                    

                    

                      
2 / 4
                      
                    

                    

                      
3 / 4
                      
                    

                    

                      
4 / 4
                      
                    

                      
                    ❮
                    ❯

                      
                    

                      

                    

                      
                    

                      
                    

                    

                      
                    

                    

                      
                    

                    

                      
                    
                  
                
                

قدم دوم :   کد CSS را اضافه کنید.
مثال :

                                .row > .column {
                  padding: 0 8px;
                }

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

                /* Create four equal columns that floats next to eachother */
                .column {
                  float: left;
                  width: 25%;
                }

                /* The Modal (background) */
                .modal {
                  display: none;
                  position: fixed;
                  z-index: 1;
                  padding-top: 100px;
                  left: 0;
                  top: 0;
                  width: 100%;
                  height: 100%;
                  overflow: auto;
                  background-color: black;
                }

                /* Modal Content */
                .modal-content {
                  position: relative;
                  background-color: #fefefe;
                  margin: auto;
                  padding: 0;
                  width: 90%;
                  max-width: 1200px;
                }

                /* The Close Button */
                .close {
                  color: white;
                  position: absolute;
                  top: 10px;
                  right: 25px;
                  font-size: 35px;
                  font-weight: bold;
                }

                .close:hover,
                .close:focus {
                  color: #999;
                  text-decoration: none;
                  cursor: pointer;
                }

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

                /* Next & previous buttons */
                .prev,
                .next {
                  cursor: pointer;
                  position: absolute;
                  top: 50%;
                  width: auto;
                  padding: 16px;
                  margin-top: -50px;
                  color: white;
                  font-weight: bold;
                  font-size: 20px;
                  transition: 0.6s ease;
                  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;
                }

                /* Caption text */
                .caption-container {
                  text-align: center;
                  background-color: black;
                  padding: 2px 16px;
                  color: white;
                }

                img.demo {
                  opacity: 0.6;
                }

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

                img.hover-shadow {
                  transition: 0.3s;
                }

                .hover-shadow:hover {
                  box-shadow: 0 4px 8px 0 rgba(0, 0, 0, 0.2), 0 6px 20px 0 rgba(0, 0, 0, 0.19);
                }

                

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