### Dependency
- #3636
- #1534

### Overview
As a developer, I need to know what resources to follow so that I can learn the best practices when it comes to designing my code.

### Action Items

- [ ] Gather a list of resources, either internal or external, pertaining to these topics:
- [ ] Accessibility
- [ ] CSS/SASS/SCSS
- [ ] Documentation/Wiki
- [ ] Design/Design System
- [ ] GitHub Actions
- [ ] HTML
- [ ] Javascipt
- [ ] Add these resources to either a pre-exisitng or new Wiki article
- [ ] Possible next steps: create a new issue for a Github action/issue template that links the Wiki in the Resources/Instructions section

### Resources/Instructions
None for now, but do note that these resources are intended to help developers on complex issues, such as those involving designing a webpage, and to help reviewers be better aware of what to look for when reviewing code. To get started, it might be good to ask the team on what resources they turn to when working on issues.
