## 點擊後按鈕出現藍色邊框？
加上這段程式碼即可解決：

&:focus {
                    outline: 0 !important;
                    box-shadow: 0 0 0 0 rgba(0, 0, 0, 0) !important;
                    -webkit-touch-callout: none;
                    -webkit-user-select: none;
                    -khtml-user-select: none;
                    -moz-user-select: none;
                    -ms-user-select: none;
                    user-select: none; 
                }
