Quick and dirty rules for making things that don't look gross
- Don't use the same color for body and header text (e.g. make headings black, text dark grey)
- Optimal line length for reading is 65 - 75 characters
- On smaller screens, make header and body text closer in size
- When tempted to use lines/borders, first try additional whitespace, variations in background color, or shadow
- Avoid colored text (it should almost always be black, grey, or white); if you're going for scannability, experiment with colored bullets, icons, and grouping
