CSS

The visual appearance of BUI controls is defined using CSS (cascading style sheets) rules. Easily change the default colors, border, and other settings by customizing these rules, all without changing any application code. See CSS API for a high-level overview of BUI CSS.

For a sample BBjSlider, refer to the BUI Showcase (demo, code). The BBjSlider defines the following style names:

.BBjSlider

.BBjSlider.bbj-disabled

.BBjSlider.bbj-focused

.BBjSlider.bbj-horizontal

.BBjSlider.bbj-vertical

.BBjSlider.bbj-labels

.BBjSlider.bbj-ticks

.BBjSlider-line

.BBjSlider-line-sliding

.BBjSlider-knob

.BBjSlider-knob-sliding

.BBjSlider-label

.BBjSlider-minor-tick

.BBjSlider-major-tick

Remarks

None.
