CSS letter-spacing property allows us to define the spaces between letters/characters in a text.

Values supported by letter-spacing include font-relative values (em, rem), parent-relative values (percentage), absolute values (px) and the normal property, which resets to the font's default.

The letter-spacing property supports negative values.

CSS Syntax

letter-spacing: normal | length | initial | inherit;

Let's see an example:

<!DOCTYPE html>
            p{letter-spacing: normal;}
            .spacing{letter-spacing: 4px;}
            .spacing-negative{letter-spacing: -4px;}

      <p>This is a paragraph.</p>
      <p class="spacing">We put more space between letters in this paragraph.</p>
      <p class="spacing-negative">But here we gave negative value and the letters almost merged.</p>


Here the result is:
