Advanced Tips for Editing MemPad’s HTML Templates

Troubleshooting Common Issues in MemPad’s HTML

1. Broken formatting or missing styles

• Cause: Incorrect HTML tags or mismatched opening/closing tags in templates.
• Fix: Validate HTML structure; ensure tags are properly nested. Replace stray characters (e.g., stray ampersands or entities). Test by simplifying to a minimal template and reintroducing parts.

2. Images not showing

• Cause: Incorrect file paths or unsupported formats.
• Fix: Use absolute paths or correct relative paths; ensure image files are in the expected folder. Prefer PNG/JPEG. Check for URL-encoding issues (spaces, special chars).

3. CSS not applying

• Cause: Inline styles overridden, wrong selectors, or stylesheet not linked.
• Fix: Confirm stylesheet link is correct and loaded. Use browser inspector or a simple HTML viewer to see computed styles. Apply !important sparingly to debug selector specificity.

4. Special characters display as entities (e.g., ‘)

• Cause: Double-escaped HTML entities or incorrect encoding.
• Fix: Ensure file encoding is UTF-8 without BOM. Decode entities where needed or avoid double-escaping when saving templates.

5. Templates not updating in the app

• Cause: Caching or wrong template file being edited.
• Fix: Restart MemPad or clear app cache. Verify you’re editing the active template file (check timestamps and file paths).

6. Links not working

• Cause: Malformed href values or missing protocol for external links.
• Fix: Use full URLs (https://…) for external links; ensure internal anchors have matching ids.

7. Unexpected behavior with scripts

• Cause: Scripts blocked by the app or sandboxing, or syntax errors.
• Fix: Avoid relying on external JavaScript; if used, test for errors with a console-capable HTML viewer. Keep scripts minimal and inline where supported.

8. Fonts rendering poorly

• Cause: Missing font files or unsupported web fonts.
• Fix: Use system fonts or include local font files. Confirm font-family fallbacks.

9. Performance issues with large templates

• Cause: Heavy images, large embedded data, or complex DOM.
• Fix: Optimize images, simplify HTML structure, and paginate or split large content.

10. Debugging checklist (quick)

1. Validate HTML (online validator).
2. Check file encoding (UTF-8).
3. Verify correct file path and that you’re editing the active template.
4. Test changes in a simple HTML viewer/browser.
5. Restart MemPad after changes.
