Indent CSS functions

[neruson]

I have some code in my template using CSS gradients that looks roughly like this:

<style>
    #gradient {
        background: linear-gradient(
            to top left,
            rgba(204,0,0,1),
            rgba(204,0,0,0)
        );
    }
</style>

However, djhtml removes the indentation in the function arguments:

<style>
    #gradient {
        background: linear-gradient(
        to top left,
        rgba(204,0,0,1),
        rgba(204,0,0,0)
        );
    }
</style>

This adds ( and ) as tokens in the CSS mode so CSS function arguments are indented one level.

Side note: I skipped creating an issue and went straight to a pull request, but I'm not sure if that's considered impolite. If so, I'm sorry, and I'm happy to go back and create one. Thank you for your hard work on this, I was really excited to discover this project!

I'm running zsh as my shell and without the quotes, this gave me this error: zsh: no matches found: .[dev]

These first two changes were automatically made by the black pre-commit hook.

Confirmed, pre-commit run --all on main produces the same changes. Not sure why, Black's version hasn't changed (although we should upgrade Black because they have released their first stable version!)

[JaapJoris]

Thank you very much for this improvement. I am sure this will make many people happy, good job!

I just have one minor change request, after that I will merge your PR and release the next version crediting you as a new contributor.

Thanks again!

Could you replace the previous 4 lines by just:

r"[\{\(\)\}]",

That would make it more similar to DjJS mode and accomplish the same thing.

Thank you for the quick review! I like the idea of being consistent with the JS mode and I've made the change you suggested.
