"breaks" with new anki version 2.1.55

[gustavosmendes]

Problem description

Anki's new version, 2.1.55, has changed some html classes. E.g. I cannot change background webview since it is named now as "--canvas".

Checklist

Please replace the space inside the brackets with an x if the following items apply:

• [ x] I've verified that I use the latest version of the add-on by redownloading it from AnkiWeb

• [ x] My issue disappears when I hold shift while starting Anki.
• [x ] I've checked if anyone else reported this problem before by looking through the issue reports. I also checked to see if there is a section about known issues in the add-on description, documentation, or README.

Relevant Changes

I'm making a list of relevant changes that I (or whoever addresses this issue) can reference later. The new color theme variables have have many more variants. Reference sass/_vars.scss file for variants.

• --medium-border, --faint-border merged into --border
• --slightly-grey-text, --text-fg merged into --fg
• --frame-bg, --window-bg merged into --canvas
• --link -> --accent-link
• --highlight-bg, --highlight-fg -> ?

Thank you for the feedback. Didn't know about these issues.

Reopening as this is a valid issue! (Just that it's a bigger scope than initially thought)
