human-highlighter v1.0.1

Demo: https://ahw.github.io/human-highlighter

This bit of code takes a chunk of text and draws randomized highlighter lines over each line on the page. It's not as simple as just wrapping text in a single <span> and applying CSS — the code takes care of figuring out where all the line wrapping occurs and creates a new highlighter line for each displayed line on the page. Afterwards it applies some CSS3 transforms (rotate and translate) to jitter the lines a bit.

Usage

Add HTML

Take a block of HTML and wrap whatever lines you want highlighted with <span class="hh"> tags like this:

<p>Upset by two nostalgias facing each other like two mirrors, he lost
his marvelous sense of unreality and he ended up recommending to all of
them that they <span class="hh">leave Macondo,</span> that they forget
everything he had taught them about the world and the human heart, that
they shit on Horace, and that wherever they might be they always
remember that <span class="hh">the past was a lie, that memory has no
return, that every spring gone by could never be recovered, and that the
wildest and most tenacious love was an ephemeral truth in the
end.</span></p>

Add JS

Put the human-highlighter code on your page. You can require human-highlighter.js if you're using Browserify, or you can just depend on having HumanHighlighter as a browser global by putting dist/human-highlighter.min.js on the page. Either way, using the following code to highlight everything in <span class="hh"> tags.

// Skip this line if you're using human-highlighter.browser.js to make
// HumanHighlighter a global.
var HumanHighlighter = require('./human-highlighter');

var highlighter = new HumanHighlighter({
    // Check the source for available configuration options
});

highlighter.highlight();
