CSS3 漸變

div{
    width: 200px;
    height: 200px;
    background-image:repeating-linear-gradient(to right, red 10%, green 20%);
}

 

漸變分爲線性漸變和徑向漸變兩種；其中：線性漸變指的是從上/下/左/右/對角方向開始的漸變，徑向漸變指的是從模塊的中心到周邊開始的漸變。

　　線性漸變：

1. 從上至下線性漸變

   div{
       width: 200px;
       height: 200px;
       background-image:linear-gradient(#e66465, #9198e5);
   }

2. 從左至右線性漸變

   div{
       width: 200px;
       height: 200px;
       background-image:linear-gradient(to right, red, yellow);
   }

    

3. 對角線性漸變

   div{
       width: 200px;
       height: 200px;
       background-image:linear-gradient(to right bottom, red, green);
   }

    

4. 使用角度的線性漸變

   div{
       width: 200px;
       height: 200px;
       background-image:linear-gradient(-90deg, red,yellow);
   }

    

5. 使用多個顏色節點的線性漸變

   div{
       width: 600px;
       height: 100px;
       background-image: linear-gradient(to right, red, orange, yellow, green, blue, indigo, violet);
   }

    

6. 使用透明度的線性漸變

   div{
       width: 200px;
       height: 200px;
       background-image: linear-gradient(to right, rgba(255,0,0,0), rgba(255,0,0,1));
   }

    

7. 重複的線性漸變

   div{
       width: 200px;
       height: 200px;
       background-image:repeating-linear-gradient(to right, red 10%, green 20%);
   }

    

　　徑向漸變：

1. 顏色節點均勻分佈（默認狀況下）

   div{
       width: 200px;
       height: 100px;
       background-image:radial-gradient(red, yellow,green);
   }

    

2. 顏色節點不均勻分佈

   div{
       width: 200px;
       height: 100px;
       background-image: radial-gradient(red 5%, yellow 15%, green 60%);
   }

    

3. 設置形狀——circle

   div{
       display: inline-block;
       width: 200px;
       height: 100px;
       background-image: radial-gradient(circle,red,yellow,green);
   }

    

4. 設置形狀——ellipse

   div{
       display: inline-block;
       width: 200px;
       height: 100px;
       background-image: radial-gradient(ellipse,red,yellow,green);
   }

    

5. 重複的徑向漸變

   div{
       width: 200px;
       height: 200px;
       background-image:repeating-radial-gradient(red, yellow 10%, green 15%);
   }

6. 不一樣尺寸大小關鍵字的使用

   .one{
       width: 100px;
       height: 100px;
       background-image:radial-gradient(closest-side at 60% 55%, red, yellow, black);
   }

    

   .two{
       width: 100px;
       height: 100px;
       background-image:radial-gradient(farthest-side at 60% 55%, red, yellow, black);
   }

    

   .three{
       width: 100px;
       height: 100px;
       background-image:radial-gradient(closest-corner at 60% 55%, red, yellow, black);
   }

    

   .four{
       width: 100px;
       height: 100px;
       background-image:radial-gradient(farthest-corner at 60% 55%, red, yellow, black);
   }
