Richtypo: HTML typography enhancer for Node

npm Build Status

Richtypo adds non-breaking spaces in right places, <nobr> and <abbr> tags, CSS classes, ampersands and hanging punctuation for special styling. It expects that your texts already have the right quotes, em-dashes and other symbols (you can use Typography Keyboard Layout).


  • Rules for English and Russian languages
  • Non-breaking spaces after prepositions and conjunctions, before em-dash, etc.
  • <nobr> for words with hyphens
  • CSS classes for ampersands and hanging punctuation
  • <abbr> for abbreviations
  • Takes care of your HTML tags
  • Simple typographer (quotes, em-dash, etc.) for user generated content (like comments)
  • No dependencies


Try it out!

const richtypo = require('richtypo');
const beautiful ='Welcome to the world of beautiful web typography — only with Richtypo.');
const awesome = richtypo.title('Beautiful &amp; Awesome Web Typography with “Richtypo”');
const ok = richtypo.lite('"Richtypo" - awesome!');

Will produce something like that:

Welcome to&nbsp;the&nbsp;world of&nbsp;beautiful web <nobr>typography&#8202;</nobr>&#8202;only with&nbsp;Richtypo.
Beautiful <span class="amp">&amp;</span> Awesome Web Typography with<span class="sldquo"> </span> <span class="hldquo"></span>Richtypo”'

Note: all methods render &nbsp; as an actual non-breaking space (\xA0).

Also look at the example page and its source.


Richtypo wraps abbreviations in <abbr> tags. It also wraps ampersands and leading quotes to allow custom styling:

Character Spacer class Character class
& .amp
.sldquo .hldquo
.slsquo .hlsquo
« .slaquo .hlaquo
.sbdquo .hbdquo
( .sbrace .hbrace

Start with something like this and customize it for your site:

/* Use small caps for abbreviations */
abbr {
  font-size: 0.875em;
  letter-spacing: 0.15em;
  margin-right: -0.15em;
/* Use the best available ampersand */
.amp {
  font-family: Baskerville, Constantia, Palatino, 'Palatino Linotype''Book Antiqua'serif;
  font-style: italic;
/* Hang leading braces and quotes into the left margin */
.sbrace { margin-right: 0.3em;  }
.hbrace { margin-left: -0.3em;  }
.slaquo { margin-right: 0.42em; }
.hlaquo { margin-left: -0.42em; }
.sbdquo { margin-right: 0.42em; }
.hbdquo { margin-left: -0.42em; }
.sldquo { margin-right: 0.42em; }
.hldquo { margin-left: -0.42em; }
.slsquo { margin-right: 0.42em; }
.hlsquo { margin-left: -0.42em; }
