Colophon for this issue

Colophon

How this issue was made

Source

github.com/webflow/webflow-skills, branch main, last pushed 21 September 2026.

Licence

MIT — the text of every skill is reproduced unmodified, frontmatter included, under the upstream licence.

Discovery

32 skills found by walking the repository tree for SKILL.md, not by matching a directory convention. One layout observed: plugins/webflow-skills/skills/*/SKILL.md.

Issue colours

Resolved from the awesome-design-md registry — hue 289°, chroma 0.190. Two accent tones are generated per issue and each is proven against its own ground before it ships: a single accent that passes AA on both light and dark paper is arithmetically impossible.

Typefaces

Display: WF Visual Sans Variable is not a face we ship; the reader's own choice is used.
Body: WF Visual Sans Variable is not a face we ship; the reader's own choice is used.
Mono: WFVisualSans-Mono is not a face we ship; the reader's own choice is used.

We never load a typeface at request time from a third-party origin, so a brand face we do not already self-host is substituted rather than fetched.

Heading repairs

1 repair applied to this skill so the document has one h1 and no skipped levels:

Shifted “38 headings” from h1 to h2 so the skill title is the only h1.

Spec compliance

64 editorial notes across 32 of 32 skills. They are printed in the margin of each skill rather than as errors here.

For Rich Text Fields:
- Parse HTML content
- Find and replace <a> tags
- Preserve other HTML formatting
- Update fieldData[fieldName] with new HTML

Batch Processing:
- Process 50 items per batch
- Show progress for large collections
- Handle API rate limits gracefully

Ask user:
"Would you like to publish the changes immediately?"
- Yes: Use data_cms_tool with action publish_collection_items

3. Test a few links manually
4. Contact Webflow support if needed

⚠️ Mixed Content Warning

Your site uses HTTPS but has 18 HTTP links.

This creates:
- Security warnings in browsers
- SEO penalties
- Trust issues for visitors

🔧 Recommendation:
Upgrade all HTTP links to HTTPS (all 18 can be auto-fixed)

Proceed with upgrade? (yes/no)

⚠️ Redirect Chain Detected

Link: https://example.com/old
  → 301 to: https://example.com/temp
  → 301 to: https://example.com/final

Recommendation: Update directly to final URL
- Improves page load speed
- Reduces redirect overhead
- Better for SEO

Fix: Update to https://example.com/final

Apply fix? (yes/no)
