Remarks
A text range has two end points. One end point is located at the beginning of the text range, and the other is located at the end of the text range. An end point also can be characterized as the position between two characters in an HTML document.
As of Microsoft® Internet Explorer 4.0, an end point is relative to text only, not HTML tags.
There are four possible end points in the following HTML:
<BODY><P><B>abc
The possible end points are:
- Before the letter a.
- Between the letters a and b.
- Between the letters b and c.
- After the letter c.
An end point cannot be established between the body and the p. such an end point is considered to be located before the letter a.
