Diagnosis
What this finding means
Enter the class without a dot in Gutenberg and use the dot only in CSS.
A finding is not a verdict. Check the displayed evidence and the design intent before changing production code.
Detection
How CSS Doctor detects it
- CSS Doctor isolates the pasted HTML and CSS in a sandboxed iframe.
- Static rules inspect source structure; runtime rules measure the rendered result.
- Evidence is ranked by intent, severity, confidence, affected area, and fix safety.
Before / After
Minimal example
Before review
追加CSSクラス: .feature-cardPossible direction
追加CSSクラス: feature-card
CSS: .feature-card { ... }The example is a starting point, not a universal patch. CSS Doctor previews Tier A and B changes before applying them and never auto-applies Tier C guidance.
Limitations
Limits and manual checks
Separate multiple class names with spaces and target only the necessary combination.
- Production stylesheets not pasted into the tool are not fetched.
- JavaScript is never executed from user input.
- Verify the result at all breakpoints and with keyboard input.
