letter-spacing
CSS letter-spacing Property
The CSS letter-spacing property allows specifying the spaces between letters/characters in a text.
Values supported by letter-spacing include parent-relative values (percentage), font-relative values (em, rem), absolute values (px) and the normal property, which resets to the font’s default.
The letter-spacing property supports negative values.
The letter-spacing is transitionable that’s why the spacing will change smoothly if a transition is defined.
The speed of transition is specified by the animation-timing-function.

Additional information
Additional information
In almost all the browsers, if you define a value computing to less than 1px (subpixel values), the letter-spacing property will not be applied.
Letter-spacing lowercase letters is not a good idea.
You can animate this property using the CSS transitions.
