Good typography improves readability and visual structure. In this chapter, we focus on properties that control spacing and subtle visual effects for text: line-height, letter-spacing, word-spacing, and text-shadow.

These properties help make text easier to read and visually balanced.

line-height

line-height controls the vertical spacing between lines of text. Browsers set a default value based on the font, but you can customize it using several formats:

line-height: multiplier | value in px | value in em | percent 
  • multiplier unitless value like 1.5 multiplies the font-size;
  • value in px specific height, e.g., 24px;
  • value in em relative value, similar to multiplier (1.4em = font-size × 1.4);
  • percent works like multiplier (120% = font-size × 1.2).

text-shadow

text-shadow adds a shadow effect to text. It accepts four values:

text-shadow: "X set" | "Y set" | "blur radius" | "color"
  • X set: horizontal shift;
  • Y set: vertical shift;
  • blur radius: softness of the shadow (0 = sharp);
  • color: any valid color, defaults to current text color.

In text formatting, there are no strict rules dictating which values must be used in specific situations. The choice of text formatting properties and values depends on the unique requirements of each project and the design vision.
