Material design: [Progress & activity](https://www.google.com/design/spec/components/progress-activity.html)
|
|
|
|
The progress bars are for situations where the percentage completed can be
|
|
determined. They give users a quick sense of how much longer an operation
|
|
will take.
|
|
|
|
Example:
|
|
|
|
<paper-progress value="10"></paper-progress>
|
|
|
|
There is also a secondary progress which is useful for displaying intermediate
|
|
progress, such as the buffer level during a streaming playback progress bar.
|
|
|
|
Example:
|
|
|
|
<paper-progress value="10" secondary-progress="30"></paper-progress>
|
|
|
|
### Styling progress bar:
|
|
|
|
To change the active progress bar color:
|
|
|
|
paper-progress {
|
|
--paper-progress-active-color: #e91e63;
|
|
}
|
|
|
|
To change the secondary progress bar color:
|
|
|
|
paper-progress {
|
|
--paper-progress-secondary-color: #f8bbd0;
|
|
}
|
|
|
|
To change the progress bar background color:
|
|
|
|
paper-progress {
|
|
--paper-progress-container-color: #64ffda;
|
|
}
|
|
|
|
Add the class `transiting` to a paper-progress to animate the progress bar when
|
|
the value changed. You can also customize the transition:
|
|
|
|
paper-progress {
|
|
--paper-progress-transition-duration: 0.08s;
|
|
--paper-progress-transition-timing-function: ease;
|
|
--paper-progress-transition-transition-delay: 0s;
|
|
}
|
|
|
|
To change the duration of the indeterminate cycle:
|
|
|
|
paper-progress {
|
|
--paper-progress-indeterminate-cycle-duration: 2s;
|
|
}
|
|
|
|
The following mixins are available for styling:
|
|
|
|
Custom property | Description | Default
|
|
-------------------------------------------------|---------------------------------------------|--------------
|
|
`--paper-progress-container` | Mixin applied to container | `{}`
|
|
`--paper-progress-transition-duration` | Duration of the transition | `0.008s`
|
|
`--paper-progress-transition-timing-function` | The timing function for the transition | `ease`
|
|
`--paper-progress-transition-delay` | delay for the transition | `0s`
|
|
`--paper-progress-container-color` | Color of the container | `--google-grey-300`
|
|
`--paper-progress-active-color` | The color of the active bar | `--google-green-500`
|
|
`--paper-progress-secondary-color` | The color of the secondary bar | `--google-green-100`
|
|
`--paper-progress-disabled-active-color` | The color of the active bar if disabled | `--google-grey-500`
|
|
`--paper-progress-disabled-secondary-color` | The color of the secondary bar if disabled | `--google-grey-300`
|
|
`--paper-progress-height` | The height of the progress bar | `4px`
|
|
`--paper-progress-indeterminate-cycle-duration` | Duration of an indeterminate cycle | `2s`
