Class: Dommy::HTMLProgressElement

Inherits:

HTMLElement

• Object
• Element
• HTMLElement
• Dommy::HTMLProgressElement

Defined in:

lib/dommy/html_elements.rb

Overview

‘<progress>` — `value` and `max` (default max=1). `position` returns `value / max` for a “determinate” progress bar, or -1 when no value is set (“indeterminate”).
