By default, there is no special CSS Editor in TextGrid. But you can install a CSS editor from the Eclipse Indigo update site:
- Click on "Help" in the menu bar and select "Install software".
- Add the url http://download.eclipse.org/releases/indigo in the Work with field.
- In the list that will form below, select from the "Web, XML, ..." category "Web Page Editor" (last but one entry).
- Finish the wizard and restart the lab.
Afterwards, existing CSS objects will be opened with the CSS editor including syntax highlighting, auto completion, an outline and a properties view.
