Adobe Dreamweaver CC 2014 v.13 - Manual (Page 15)

Code View improvements
Line number highlighting
Line numbers where the IP is present are highlighted in code view, live code, design view, live view, and code inspector. Line numbers are also
highlighted in case of syntax error.
Tag and attribute highlighting
The tag on which the Insertion Point (IP) is present is highlighted. If IP is on the opening tag, the closing tag is also highlighted and vice-versa.
Highlighting works with mouse clicks as well as keyboard navigation keys. Tag highlighting works with Live code and code inspector as well.
You can change the color of the tag highlighting in Preferences (Code Coloring).
