Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Inside the component controller JavaScript file (.js)
Why it's wrong here
Incorrect. Component styling should reside in CSS files, not JavaScript logic.
- ✓
In the component's cascading style sheet file (.css)
Why this is correct
Correct. SLDS styling hooks are defined inside the component's CSS file.
- ✗
In a separate Static Resource uploaded to Salesforce
Why it's wrong here
Incorrect. While static resources can hold CSS, styling hooks are native to component stylesheets.
- ✗
In the component's configuration file (.js-meta.xml)
Why it's wrong here
Incorrect. The meta-xml file defines component metadata and targeting, not CSS styling overrides.
