[Small Feature Request] Add CSS class for `@p` command

[parmi93]

Currently the @p and @c commands when rendered in HTML both generate the same output (<code></code>), it would be nice if a CSS class was added by default to distinguish the two commands.

Like:

• @p --> <code class="param"></code>
• @c --> <code class="code"></code>

This way the User would have the possibility to define his own CSS classes (.param{} and .code{}), to be able to visually distinguish more easily when referring to parameters and when referring to simple code.

I'm not asking you to create the related CSS classes, but simply to add the class= attribute in the generated HTML code.

Same also applies for the commands \a, \e and \em.

It should also be taken into consideration what to do with explicit <code> tags and tags like <tt> that are translated into <code> tags. They can have attributes, so a distinction can be made, but maybe also an extra class attribute should be added here.

I've just pushed a proposed patch, pull request #11243

[doxygen]

This issue was previously marked 'fixed but not released',
which means it should be fixed in doxygen version 1.13.0.
Please verify if this is indeed the case. Reopen the
issue if you think it is not fixed and please include any additional information
that you think can be relevant (preferably in the form of a self-contained example).

I'm not sure if it's a problem related to the introduction of the param class.

/**
 * @p key/@p value pair was added to the dictionary successfully.
 */
void my_func(int key, int value);

Result:

I was expecting this:

[albert-github]

No this does not have to do with changes for this issue, I can see it also in e.g. doxygen version1.12.0, so please file a new issue for this.
(also a line like @b key/@p value pair was added to the dictionary successfully. will give some unexpected results).

Note: might be related to #8706 / #9207
