旋转木马轮播图源码与制作过程 html+css+js

能轮播，点击按钮能切图。鼠标位于图片或按钮上停止轮播。

## 实现（可跟着一步一步实现）： ##

**1. 定义标签（video是背景视频，.but1与.but2是左右两个按钮，main与.haha是底层盒子，.box就是旋转的8张图）：**

[\- -d是var函数的使用，var函数的可以去看这个文章的开头部分][- -d_var_var]  
**2. 定义底层盒子基本样式：**

main{ 
                position: relative;
                width: 220px;
                height: 130px;
                perspective: 800px;
            }
            .haha{ 
                position: relative;
                width: 100%;
                height: 100%;
                transform-style: preserve-3d;
                transition: all 1s;
            }

position: relative;相对定位。  
perspective: 800px;改变3D元素是怎样查看透视图。  
transform-style: preserve-3d;子元素将保留其 3D 位置。  
transition: all 1s; 过渡，后面切图时的时间。

**3. 定义按钮基本样式：**

.but1,.but2{ 
                position: absolute;
                top: 50%;
                transform: translateY(-50%);
                width: 50px;
                height: 50px;
                font-size: 30px;
                color: white;
                opacity: 0.8;
                line-height: 50px;
                text-align: center;
                border-radius: 50%;
                cursor: pointer;
                user-select: none;
            }
            .but2{         
                left: -320px;           
            }
            .but1{  
                right: -320px;
            }

transform：translateY：偏移。  
opacity：0.8；透明度。  
text-align: center; 文本居中。  
cursor: pointer; 鼠标外观样式。  
user-select: none; 文本不可选。

**4. 经过与点击按钮样式变化：**

.but1:hover,.but2:hover{ 
                box-shadow: inset 0 0 5px rgb(18, 208, 221);
                opacity: 1;
            }
            .but1:active,.but2:active{ 
               /* background-color: rgb(22, 163, 81); */
               box-shadow: inset 0 0 5px rgb(18, 208, 221),
               inset 0 0 10px rgb(18, 208, 221),
               inset 0 0 15px rgb(18, 208, 221);
            }

box-shadow：阴影。  
opacity: 1; 透明度。

**5. 图片的基本样式：**

.box{ 
                position: absolute;
                width: 100%;
                height: 100%;
                transform: rotateY(calc(var(--d) * 45deg)) translateZ(295px); 
            }
            .box img{ 
                width: 100%;
                height: 100%;                    
            }

transform: rotateY(calc(var(–d) \* 45deg)) translateZ(295px); 每张图旋转与偏移相应的位置得到旋转木马的立体效果。可自己调节~

**6. 开始js部分，获取元素与定义变量：**

var haha = document.querySelector(".haha");
            var but1 = document.querySelector(".but1");
            var but2 = document.querySelector(".but2");
            /* 旋转角度 */
            var zhuan = 0;
            /* 设置轮播定时器 */
            var  lunbo =  setInterval(fn,3000);

**7. 点击向左按钮事件，点一次转 -45deg：**

but1.addEventListener('click',function(){ 
                zhuan = zhuan - 45;
                haha.style.cssText = ` transform: rotateY(${ zhuan}deg); `;
            })

**8. 点击向右按钮事件，点一次转 45deg：**

but2.addEventListener('click',fn);
     function fn(){ 
                zhuan = zhuan + 45;
                haha.style.cssText = ` transform: rotateY(${ zhuan}deg); `;
            }

**9. 鼠标经过按钮与图片时停止轮播定时器，离开图片与按钮开始轮播定时器（简单粗暴）：**

but1.addEventListener('mouseover',function(){ 
                clearInterval(lunbo);
            });
            but1.addEventListener('mouseout',function(){ 
                lunbo =  setInterval(fn,3000);
            });
             but2.addEventListener('mouseover',function(){ 
                clearInterval(lunbo);
            });
            but2.addEventListener('mouseout',function(){ 
                lunbo =  setInterval(fn,3000);
            });
     haha.addEventListener('mouseover',function(){ 
                clearInterval(lunbo);
            });
           haha.addEventListener('mouseout',function(){ 
                lunbo =  setInterval(fn,3000);
            });
