css代码怎样改变火狐浏览器中滚动条样式

css代码怎样改变火狐浏览器中滚动条样式

　　CSS无法控制滚动条的样式。这里推荐几块滚动条美化的插件给你。
　　
1. Windows：全屏窗口滚动插件

　　该插件可以很好地实现全屏滚动，每滚动一次即为一屏。比如，用户浏览下一屏幕内容时，只需手动滚动到某一位置，该插件会自动滚动显示下一屏全部内容。对于浏览类似于PPT的内容时比较实用。

　　2. Jquery Scroll Follow：滚动跟随插件
　　该插件可以使DOM对象随着页面的滚动而移动。你可以设置滚动的速度、偏移等参数。

　　3. 列表滚动插件
　　该插件可以为任意列表添加上滚动效果。你可以自定义列表的滚动方向和滚动速度。

　　4. Sly：灵活的基于ITEM的滚动插件

　　SLY提供了很多基于项目（如图像/内容画廊）的滚动选项，支持水平和垂直方向的无限滚动。

5. Coverscroll

　　仿苹果的CoverFlow设计，支持滚动条、鼠标滚轮和手势来滚动查看。

6. Sticky
　该插件可以让你的页面中的任何元素在滚动过程中始终可见

7. Tiny Scrollbar：一个轻量级的JQUERY插件

8. Sticky Float：另一个滚动跟随插件

9. Page Scroller：漂亮实用的滚动导航

10. Custom Srollbar：自定义内容滚动条插件

11. Scroll Up：一个轻量级的滚动到顶部插件2015-12-15
