效果（完整代碼在底部）

其實(shí)實(shí)現(xiàn)并不難，都是重復(fù)的代碼比較多。

實(shí)現(xiàn)（可跟著一步一步寫）：

1. 先定義基本標(biāo)簽：

<!-- 血輪眼 -->
    <div class="zuo">
        <!-- 眼睛最中間那個(gè)黑點(diǎn) -->
        <div class="zuoZong">
            <!-- 三勾玉所在的圈 -->
            <div class="zuoYu">
                <!-- 三個(gè)勾玉 -->
                <span class="yu"></span>
                <span class="yu"></span>
                <span class="yu"></span>
            </div>
        </div>
    </div>
    <!-- 輪回眼 -->
    <div class="you">
        <!-- 眼睛最中間那個(gè)黑點(diǎn) -->
        <div class="dian"></div>
             <!-- 3個(gè)輪回圈 -->
            <div class="youYu">                        
                <span class="quan" style="--r:2;"></span>
                <span class="quan" style="--r:3;"></span>
                <span class="quan" style="--r:4;"></span>
            </div>       
    </div>

2. 定義左右眼的基本css樣式：

.zuo , .you{ 
            width: 250px;
            height: 120px;
            background-color: rgb(255, 255, 255);
            border-bottom: 5px solid rgb(70, 70, 70);
            overflow: hidden;
            position: relative;
        }

border-bottom: 5px solid rgb(70, 70, 70); 給個(gè)灰色的眼底。

overflow：溢出隱藏。

position: relative; 相對(duì)定位。

3. 開始先定義血輪眼的基本樣式：

.zuo{
            transform: translateX(-135px);
            border-radius: 0 120px 0 120px;
            box-shadow: inset 3px 2px 3px  rgba(17, 17, 17, 0.8);
        }

transform: translateX(-135px); 向左偏移，讓兩眼分開。

border-radius：給兩個(gè)角設(shè)置弧度，形成眼睛形狀。

bos-shadowL給眼角一點(diǎn)陰影。

4. 設(shè)置眼球?qū)捀叩龋?/strong>

.zuo::after{
            content: '';
            position: absolute;
            top: 50%;
            left: 50%;
            transform: translate(-50%,-50%);
            width: 95px;
            height: 95px;
            border-radius: 50%;
            border: 2px solid #000;
            animation: colour 2s linear forwards;
        }
        @keyframes colour{
            0%,30%{
                background-color: rgb(0, 0, 0);
            }
            100%{
                 background-color: rgb(255, 4, 4);
             }
         }

5. 設(shè)置眼球正中間的黑點(diǎn)，都是些定位大小啥的，然后設(shè)置動(dòng)畫然它慢慢變大：

 .zuoZong{
            position: absolute;
            top: 50%;
            left: 50%;
            transform: translate(-50%,-50%);
            width: 0px;
            height: 0px;
            border-radius: 50%;
            background-color: rgb(0, 0, 0);
            z-index: 1;
            animation: da 3s linear forwards;
        }
        @keyframes da{
            100%{
                width: 15px;
            height: 15px;
            }
        }

6. 設(shè)置三勾玉所在的圈，設(shè)置動(dòng)畫讓其顯示與旋轉(zhuǎn)：

.zuoYu{
            position: absolute;
            top: -25px;
            left: -25px;
            bottom: -25px;
            right: -25px;
            border-radius: 50%;
            border: 2px solid rgb(0, 0, 0);
            animation: zhuan 2s linear 2s forwards;
            opacity: 0;
        }
        @keyframes zhuan{
           
            100%{
                opacity: 1;
                transform: rotate(720deg);
            }
        }

7. 制作三勾玉，先做一個(gè)圓，再用雙偽類制作一個(gè)圓弧，兩者結(jié)合就是勾玉了：

.zuoYu .yu{
             position: absolute;
             width: 15px;
             height: 15px;
             border-radius: 50%;
             background-color: rgb(0, 0, 0);

        }
        .zuoYu .yu::after{
            content: '';
            position: absolute;
            top: -6px;
            left: -1px;
            width: 6px;
            height: 20px;
            border-radius: 50%;
            border-left: 6px solid rgb(0, 0, 0);
        }

border-radius: 50%;

border-left: 6px solid rgb(0, 0, 0);

先讓偽類為圓，再只設(shè)置一條邊框，圓弧形成，再定位在父元素上，形成勾玉。

8. 給勾玉設(shè)置動(dòng)畫，讓其從最中間變大旋轉(zhuǎn)到勾玉所在的圈：

  .zuoYu .yu:nth-child(1){
            animation: yu1 2s ease-in 2s  forwards;
        }
        @keyframes yu1{
            0%{
                opacity: 0;
                left: 50%;
                top: 50%;                
                transform:translate(-50%,-50%)  scale(0.1) ;
            }
            100%{
                left: 50%;
                top: -9%;
                transform: scale(1) rotate(80deg);  
            }
        }

left: 50%;
top: 50%; 在最中間。
opacity：透明。
scale(0.1)；縮小。
100%{…}到對(duì)應(yīng)位置，同時(shí)變不透明和放大成正常大小。

9. 一樣的，給其它兩個(gè)勾玉動(dòng)畫：

.zuoYu .yu:nth-child(2){
            animation: yu2 2s ease-in 2s forwards; 
        }
        @keyframes yu2{
            0%{
                opacity: 0;
                left: 50%;
                top: 50%;
                
                transform: translate(-50%,-50%) scale(0.1) ;
            }
            100%{
                top: 60%;
                left: -9%;
                transform: scale(1) rotate(-60deg);  
            }
        }
        .zuoYu .yu:nth-child(3){          
            animation: yu3 2s ease-in 2s forwards;
        }
        @keyframes yu3{
            0%{
                opacity: 0;
                right: 50%;
                top: 50%;
                
                transform: translate(-50%,-50%) scale(0.1);
            }
            100%{
                top: 60%;
                right: -9%;
                transform: scale(1) rotate(180deg);  
            }
        }

10.給兩個(gè)眼睛都設(shè)置一個(gè)白點(diǎn)，相當(dāng)于反光效果吧，至此血輪眼做完了：

.zuo::before,.you::before{
            content: '';
            position: absolute;
            left: 38%;
            top: 30%;
            width: 12px;
            height: 12px;
            border-radius: 50%;
            background-color: rgb(255, 255, 255);
            z-index: 10;
        }

position: absolute;
left: 38%;
top: 30%; 定位相應(yīng)的位置。
background-color: rgb(255, 255, 255); 白色。
z-index: 10; 設(shè)置為10，顯示在最上層。

11.設(shè)置輪回眼基本css樣式，跟血輪眼一樣：

 .you{
            transform: translateX(135px);
            border-radius:  120px 0 120px 0;
            box-shadow: inset -3px 2px 3px  rgba(17, 17, 17, 0.8);
        }

12.設(shè)置眼球?qū)捀叩龋?/strong>

.you::after{
            content: '';
            position: absolute;
            top: 50%;
            left: 50%;
            transform: translate(-50%,-50%);
            width: 95px;
            height: 95px;
            border-radius: 50%;
            border: 2px solid #000;
            animation: youcolor 2s linear forwards;
         }
         @keyframes youcolor{
            0%,30%{
                background-color: rgb(0, 0, 0);
            }
            100%{
                 background-color: rgb(144, 130, 183);
             
             }
         }

position: absolute; 絕對(duì)定位
top: 50%;
left: 50%;
transform: translate(-50%,-50%); 居中對(duì)齊。
animation：設(shè)置動(dòng)畫，讓其變紫色。forward：繼承最后一幀的屬性。
background-color: rgb(0, 0, 0); 黑色
background-color: rgb(144, 130, 183); 紫色。

13. 設(shè)置眼球最中間的黑點(diǎn)，跟血輪眼也差不多：

.dian{       
             position: absolute;
            top: 50%;
            left: 50%;              
            background-color: #000;
            transform: translate(-50%,-50%);
            border-radius: 50%;
            z-index: 10;
            animation: youda 3s linear forwards;
         }
         @keyframes youda{
             0%{
                height: 0px;
            width: 0px;
             }
             100%{
                height: 15px;
            width: 15px;
             }
         }

14. 設(shè)置輪回眼每個(gè)圈，同時(shí)設(shè)置動(dòng)畫讓其變大：

 .youYu{
            position: absolute;
          top: 50%;
          left: 50%;
          transform: translate(-50%,-50%);
       }
       .quan{
           position: absolute;
           border-radius: 50%;
           border: 2px solid #000;
           z-index: calc(1 - var(--r));
           animation: zhi 2s ease-out 2s forwards;
       }
       @keyframes zhi{
           0%{
            top: calc(var(--r) * 1px);
           left: calc(var(--r) * 1px);
           right: calc(var(--r) * 1px);
           bottom: calc(var(--r) * 1px);
           }
           100%{
            top: calc(var(--r) * -35px);
           left: calc(var(--r) * -35px);
           right: calc(var(--r) * -35px);
           bottom: calc(var(--r) * -35px);

               background-color: rgb(187, 177, 214);
           }
       }

z-index: calc(1 - var(–r)); 計(jì)算，讓最開始的圈顯示在最上層。
animation：設(shè)置動(dòng)畫，讓輪回圈慢慢變大，同時(shí)變成紫色。
