I've been playing around with it for you.
First I set the buttons to be 10px x 10px to make it easier, and created 4 10 by 10 arrows pointing left, right, up and down.
Then I set the background-size to be 100%, to scale it correctly.
Then i set the correct image to each button using, the :increment, :decrement, :horizontaland :verticalselectors.
The images are on my public dropbox right now, but you can add your own.
我一直在为你玩弄它。首先，我将按钮设置为 10px x 10px 以使其更容易，并创建了 4 个 10 x 10 箭头，指向左、右、上和下。然后我将背景大小设置为 100%，以正确缩放。然后，我使用的正确的图像设置为每个按钮:increment，:decrement，:horizontal和:vertical选择器。这些图像现在在我的公共保管箱中，但您可以添加自己的。
Here's the updated code: http://jsfiddle.net/Nk3NH/2/
这是更新的代码：http: //jsfiddle.net/Nk3NH/2/
the code I wrote was this:
我写的代码是这样的：
::-webkit-scrollbar-button {
background-size: 100%;
height: 10px;
width: 10px;
-webkit-box-shadow: inset 1px 1px 2px rgba(0,0,0,0.2);
}
::-webkit-scrollbar-button:horizontal:increment {
background-image: url(https://dl.dropboxusercontent.com/u/55165267/icon2.png);
}
::-webkit-scrollbar-button:horizontal:decrement {
background-image: url(https://dl.dropboxusercontent.com/u/55165267/icon4.png);
}
::-webkit-scrollbar-button:vertical:increment {
background-image: url(https://dl.dropboxusercontent.com/u/55165267/icon3.png);
}
::-webkit-scrollbar-button:vertical:decrement {
background-image: url(https://dl.dropboxusercontent.com/u/55165267/icon.png);
}
EDIT: Managed to get the scroll buttons next to each other as OP wanted by adding these styles:
编辑：通过添加这些样式，按照 OP 的需要，设法使滚动按钮彼此相邻：
::-webkit-scrollbar-button:end {
display: block;
}
::-webkit-scrollbar-button:start {
display: none;
}
Updated code with base64 images instead of broken links:
使用 base64 图像而不是断开的链接更新代码：

I wanted to do the same thing, but without having to use background-images for the arrows. My solution is to use overlapping background gradients:
我想做同样的事情，但不必为箭头使用背景图像。我的解决方案是使用重叠的背景渐变：
::-webkit-scrollbar-button:vertical:start:decrement {
background:
linear-gradient(120deg, #696969 40%, rgba(0, 0, 0, 0) 41%),
linear-gradient(240deg, #696969 40%, rgba(0, 0, 0, 0) 41%),
linear-gradient(0deg, #696969 30%, rgba(0, 0, 0, 0) 31%);
background-color: #b6b6b6;
}
::-webkit-scrollbar-button:vertical:end:increment {
background:
linear-gradient(300deg, #696969 40%, rgba(0, 0, 0, 0) 41%),
linear-gradient(60deg, #696969 40%, rgba(0, 0, 0, 0) 41%),
linear-gradient(180deg, #696969 30%, rgba(0, 0, 0, 0) 31%);
background-color: #b6b6b6;
}
::-webkit-scrollbar-button:horizontal:end:increment {
background:
linear-gradient(210deg, #696969 40%, rgba(0, 0, 0, 0) 41%),
linear-gradient(330deg, #696969 40%, rgba(0, 0, 0, 0) 41%),
linear-gradient(90deg, #696969 30%, rgba(0, 0, 0, 0) 31%);
background-color: #b6b6b6;
}
::-webkit-scrollbar-button:horizontal:start:decrement {
background:
linear-gradient(30deg, #696969 40%, rgba(0, 0, 0, 0) 41%),
linear-gradient(150deg, #696969 40%, rgba(0, 0, 0, 0) 41%),
linear-gradient(270deg, #696969 30%, rgba(0, 0, 0, 0) 31%);
background-color: #b6b6b6;
}

Because this is the first solution found on Google, when you have problems showing multiple buttons on one scrollbar, I will leave this answer here.
You have to add this lines to hide the extra buttons:
因为这是在 Google 上找到的第一个解决方案，当您在一个滚动条上显示多个按钮时遇到问题，我会在这里留下这个答案。
您必须添加此行以隐藏额外的按钮：
::-webkit-scrollbar-button:vertical:start:increment,
::-webkit-scrollbar-button:vertical:end:decrement,
::-webkit-scrollbar-button:horizontal:start:increment,
::-webkit-scrollbar-button:horizontal:end:decrement {
width: 0;
height: 0;
}
