Skipping content by CSS class and/or ID

[Ade]

Is it possible to identify sections of HTML pages to skip over by specifiying the CSS class and/or ID of an html container?

I understand it's possible by adding comment tags directly into the html but it would be even better to be able to specify this without amending the html directly. Could this be done?

While not such a bad idea, this is not an option in the current software.

You need to add tags to exclude page content. As per this FAQ,
Q. How do I prevent parts of my webpage from being indexed (eg. exclude navigation menus, or page footers)?
