I am trying to find out if there is a way to write a css rule that
will cause a tag with a certain id attribute to automatically belong
to a certain class and inherit all the properties already defined for
that class.

In other words, I would like to produce the effect of the following code

#myid, .myclass { blah-blah-blah }

but by writing something in the following form:

.myclass { blah-blah-blah }
#myid { what goes here? }

FYI, I am doing this because the rule ".myclass { blah-blah-blah }" is
defined in a stylesheet outside of my administrative control and
defines rules that are complex and subject to change. Thus, it is not
acceptable for me to have to modify, reproduce, or even view the
content of "blah-blah-blah".

A helpful answer will tell me the syntax I need, or else tell me why
it is impossible in terms of css language definition.

Hi,

Can you not add the class attribute to the elements with the given IDs?

Thanks.

No, I cannot add the class attribute to the elements because the
elements are generated dynamically on the server side by a system out
of my control.

As you can read here: http://archivist.incutio.com/viewlist/css-discuss/2685

In CSS it is not possible to define one element in terms of another.


However, if you can accept a JavaScript solution: it is possible to
read the style of YOURCLASS and create a new style rule to be applied
to YOURID. The result is exactly what you need... but achieved with
JavaScript.
