// # Content Helper
|
|
// Usage: `{{content}}`, `{{content words="20"}}`, `{{content characters="256"}}`
|
|
//
|
|
// Turns content html into a safestring so that the user doesn't have to
|
|
// escape it or tell handlebars to leave it alone with a triple-brace.
|
|
//
|
|
// Enables tag-safe truncation of content by characters or words.
