❓ FAQ
QWhat happens if progress has no value attribute?
AWithout
value, the bar is indeterminate — browsers show a sliding or spinning animation for processing with unknown completion. Once value is set (between 0 and max), it shows determinate progress.QWhat is the default max of progress?
AThe default max is 1, so
value='0.5' means 50%. Set max='100' and value becomes a plain 0-100 number, which reads better. Values above max are clamped to max.QCan the progress bar be styled?
AYes, but it needs vendor pseudo-elements: WebKit uses
progress::-webkit-progress-bar and progress::-webkit-progress-value; Firefox uses progress::-moz-progress-bar. Cross-browser styling is fiddly — for elaborate designs, a CSS-drawn progress bar may be simpler.🏷️ Related Tags
