Best way of adding custom CSS as part of a plugin
 

I am working on a plugin, and I like the new product/plugin system very much. I just need to add a couple of custom style definitions to the main CSS file, but I wonder how that can be done in the best way. I could just add it to EXTRA or EXTRA2, but then uninstall becomes difficult. Another option is to put it in a template, and load it with misc.php?do=page&template=nameoftemplate, which I also use for my javascript file. Is there an option which I have overlooked?

[edit]
The last option does not work, because FireFox doesn't like CSS files with Content-type: text/html.

I would like to know this too.
Anyone?

I'm also wondering why the main CSS is inline and not in an external file.

That's an option. Make clientscript/vbulletin_css/ writable , enable the setting in the options menu and vBulletin will write the CSS to that directory.

is this a plugin that will enable adding new css selector fields in the style manager? Like this?

how to make it writeable?

No, my plugin won't add new fields to the Admin CP CSS editor.

chmod 777 should make it writable.

bump.

Figured out a good way to do this and used it in my new modification https://vborg.vbsupport.ru/showthread.php?t=110401

I might be mistaking, but does your method cause that your CSS is added to the CSS file which is cached in clientscript/vbulletin_css?

I'd just use inline CSS personally, or add it to the headinclude template. Not allowing proper CSS addition via plugins is a pretty chronic oversight in my eyes on Jelsoft's part.
