The letter-spacing
property controls the amount of space between each letter in a given element or block of text.
Syntax:
letter-spacing: normal|length|initial|inherit;
The most important point to note when using letter-spacing
is that the value specified does not change the default, it is added to the default spacing the browser applies (based on the font metrics). letter-spacing
also supports negative values, which will tighten the appearance of text, rather than loosening it.
