Asterisks vs Underscores
When to Use Double Asterisks (**)
Best for:
- • General bold text
- • Most common choice
- • Consistent with italic (*)
- • Mid-word emphasis
Example:
This is **really** important. The word super**star** performance.
When to Use Double Underscores (__)
Best for:
- • When text contains asterisks
- • Alternative style choice
- • Headers and titles
- • Consistent with italic (_)
Example:
__Important Note:__ Read carefully. Use __UPPERCASE__ for emphasis.
Best Practices
✅ Best Practices
- Be consistent: Choose either ** or __ and stick to it throughout your document
- Use for importance: Bold should indicate importance, not just visual appeal
- Don't overuse: Too much bold text loses its impact
- Consider hierarchy: Use bold for headings, key terms, and important points
- Maintain readability: Ensure bold text doesn't overwhelm the content
❌ Common Mistakes
- Mixing markers: Using both ** and __ randomly in the same document
- Spaces around markers: Using "** bold **" instead of "**bold**"
- Single markers: Using "*bold*" instead of "**bold**"
- Overemphasis: Making too much text bold
- Wrong semantic use: Using bold for code or technical terms
Common Issues and Solutions
❌ Problem: Single vs Double Markers
Wrong (creates italic):
This is *not bold* text. This is _also not bold_ text.
Correct (creates bold):
This is **bold** text. This is __also bold__ text.
Use double markers (**) or (__) for bold, single markers for italic.
❌ Problem: Spaces Around Markers
Wrong:
This is ** not bold ** text. This is __ also not bold __ text.
Correct:
This is **bold** text. This is __also bold__ text.
Don't add spaces between the markers and the text.
❌ Problem: Unmatched Markers
Wrong:
This is **missing closing marker text. This is __mixed markers** text.
Correct:
This is **properly closed** text. This is __consistently marked__ text.
Always use matching opening and closing markers of the same type.
