Have you read the Contributing Guidelines on issues?

• I have read the Contributing Guidelines on issues.

Description

When using a category index page (e.g. docs/how-to/index.md) and providing front-matter meta data

---
sidebar_class_name: green
---

i would expect, that this is applied to the category's <li class="green"> element, but it is not.

Current workaround: _category_.json with

// _category_.json
{
  "className": "green"
}

Self-service

• I'd be willing to address this documentation request myself.
