adding extra custom css file to balance theme

Hi

I have been trying unsuccessfully to add and extra stylesheet to the balance theme I intend to use on my site.

I have looked at several explanations, either I don’t understand or they don’t work, including wp_enqueue_style.

I can’t figure out how to get the theme to call the css file and use it along side the default existing stylesheet.

I just want to tweek a few styles to overwrite the default, but I would rather do it in a separate file because it is easier to edit.

Many thanks
Richard
