1.滚动条样式

::-webkit-scrollbar {width: 10px;height: 10px;z-index: 101;
}
::-webkit-scrollbar-thumb {border-radius: 5px;background: #cecece;
}
::-webkit-scrollbar-track {// background: #f5f5f5be;background: rgba(33, 85, 163, 0);
}
::-webkit-scrollbar-button {display: none;
}
::-webkit-scrollbar-corner {display: none;
}

2.垂直滚动条上下留空

		::-webkit-scrollbar-button:vertical:start:increment {display: block;height: 30px;background-color: transparent;}::-webkit-scrollbar-button:vertical:end:increment {display: block;height: 30px;background-color: transparent;}
