Design

3. Design sin: filling all four corners of a layout instead of grouping elements thoughtfully
4. Design sin: a single short line stranded alone at the top of a column
6. Design principle: echoing visual elements throughout a piece to create unity and consistency
7. Typography: spacing adjusted between two specific characters
8. Design principle: arranging elements to signal their relative order of importance
9. Design sin: a lonely line left by itself at the bottom of a text block
13. Color theory: colors sitting directly opposite each other on the color wheel
16. Design principle: every element should have a visual connection to something else on the page
17. Typography: the part of a lowercase letter that rises above the x-height
20. Color theory: the intensity or purity of a color
21. Design sin: justified text that creates distracting white gaps running down a paragraph
22. Typography: a typeface with small finishing strokes at the ends of letterforms
23. Typography: vertical space between lines of type, measured baseline to baseline

1. Typography: the invisible line on which most letters sit
2. Design sin: a photo stretched or squeezed out of its original proportions
4. Design principle: intentional empty area that gives content room to breathe
5. Color theory: a color scheme built from variations of a single hue
10. Color theory: the pure name of a color, such as red, blue, or yellow
11. Design principle: using opposing values, sizes, or colors to create visual interest and hierarchy
12. Design sin: negative space caught in the interior of a layout rather than pushed to the edges
14. Color theory: a color lightened by mixing it with white
15. Design principle: grouping related items together to reduce clutter and show organization
18. Design sin: every element placed on a central axis with no strong edge for the eye to follow
19. Design sin: thick decorative boxes and borders that overwhelm a layout
24. Color theory: colors that sit side by side on the color wheel
