Interactive demonstrations of pretext — a pure-arithmetic text layout engine. Zero DOM reads, instant measurement, proportional font precision.

HTML is designed to collapse white space by default. In order words, all series of white spaces characters (spaces, tabs, line feeds...) are replaced by a single space on rendering.

Take a look at our collection of ASCII artwork code snippets that have been enhanced and animated with CSS & JavaScript.

I made the font monospace and added white-space: pre; but I need something else to help the photo become more visible. I also added the pre tag per what I read on another stackoverflow post.

Let's break down how to achieve this using HTML and CSS, along with common pitfalls and alternative approaches. The core idea here is to use a single element and leverage CSS properties to simulate the "background inside the lines" effect.

Learn how to effectively parse ASCII art into HTML format using Java or JavaScript with detailed explanations and code examples.

Traditional ASCII art assumes monospaced fonts where every character has the same width. With proportional fonts, characters like 'W' are wider than 'i', so naive grid-based placement breaks down. Pretext solves this by measuring each ASCII character's width with prepareWithSegments ().

A high-performance cinematic ASCII engine demo that renders the iconic "Bad Apple!!" shadow art using proportional variable typography instead of traditional monospaced characters.

ASCII art is always done on a fixed-width font like Courier New or Fixedsys, never on a proportional font like Arial or Times New Roman. It can be made in Notepad or MS-DOS Edit, but there are also some specific programs for making ASCII art.
