Scroll Marker

Scroll Marker插件简介

Scroll Marker插件描述

Adds a customizable line ("Marker") to the bottom of web pages which helps users visually keep their place when the page is scrolled.  

After the page scrolls, the Marker will move up with the page,  remain in place f a moment to help the user keep track of where they left off.  After a set period of time, the Marker will redraw again near the bottom of the freshly scrolled web page, awaiting the next scroll.

The Marker col, opacity, width  distance from the bottom of the web page can be changed by the user.  Also, the delay after scrolling befe the Marker redraws itself is also configurable.

Scroll Marker does not set cookies, track users  webpages,  does not communicate  exchange data with anyone.  It simply uses basic JavaScript to temparily insert  manipulate its "marker" object in web pages after they load.  The only infmation it reads are the size  scrolling dimensions of Chromes browser windows.
