widow

Add non breaking spaces to the ends of block level elements.

Install via npm:

npm install widow --save

Why?

To ensure good typographic style, widow adds non breaking spaces to your HTML content automatically. It's lightweight and doesn't depend on jQuery; and its node API will allow you to transform content on the server before it reaches the client.

In node, widow uses cheerio to modify a string of HTML; in the browser, it will modify the current document using querySelectorAll.

Example (node)

var widow = require('widow');
var htmlStr = '<h1>Donut topping lollipop gummi bears</h1>';

console.log(widow(htmlStr));
// => <h1>Donut topping lollipop gummi&nbsp;bears</h1>

Example (browser)

Bundle this code with browserify:

var widow = require('widow');
widow();

API

widow([html,][options])

The html argument is only required in node. In the browser it will modify the current document.

Options

selectors

Type: Array

Which selectors widow should transform. By default it only transforms headings, blockquotes, list items, paragraphs and table cells. Override this with an array of query selectors to limit widow's scope.

maxLength

Type: Integer Default: 50

You can specify a maximum length at which widow should apply a non-breaking space - this is useful if you have headings with large font sizes, and you tend to use long words in them.
