text-shadow: 1px  1px 1px #ccc,  
                  0 0 10px #fff,             
                   0 0 20px #fff,
                   0 0 30px #fff,
                   0 0 40px #ff00de,
                   0 0 70px #ff00de,
                   0 0 80px #ff00de, 

下面每一行跟上面属性一样，只是像素值和颜色不一样，为什么要重复写好几遍呢，求解。呢。。。。                   0 0 100px #ff00de,
                   0 0 150px #ff00de;
