Hi Yuan,

> Also,the scroll bar color can change?

It is possible to change the scollbar colors but it's somewhat laborious since you can't just tweak a single color, when you use a custom scrollbar selector it will replace the default system drawn scrollbar entirely and so you will have to specify a lot of different properties yourself to make up all the pieces.

The different selectors are described here:

Also some info here:

So for a quick example, if you add this into moi.css you will get a weird looking red and yellow 2 color scrollbar:

::-webkit-scrollbar {
background:red;
}

::-webkit-scrollbar-thumb {
background:yellow;
}
