Implementation
Best Practices

40. http://extens.is/webv
Bigger Body Text
• Legible ≠ Comfortable!
• Most web text unnecessarily small
• Average 9–12 px
• Suggested default: 14–16 px
• Ideal size varies by font
• Different x-height
• Minimum legible varies

41. http://extens.is/webv
Limit & Control Line Length
• Impacts reading comfort
• Aim for 55–75 characters/line
• Type size ×30 is a good start
• width: 30em;
• Or, use max
• max-width: 30em;

42. http://extens.is/webv
Use OpenType features in CSS
• Contextual Alternates
• Ligatures
• Contextual Ligatures
• Kerning
• OptimizeLegibility (Older Browser Support)

43. http://extens.is/webv
Use OpenType features in CSS
• OpenType is font file type
• OpenType features ≠ file type
• Not all features are in all fonts
