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.

The BUI BBjLineChart is implemented as an <image> element. It defines the following style names:

.BBjLineChart

.BBjLineChart.bbj-disabled

Use CSS styles that would work with images, for example:

.BBjLineChart

{

opacity: 0.4;

border-radius: 15px;

border-width: 2px;

box-shadow: 7px 7px 5px rgba(50, 50, 50, 0.5);

}

.BBjLineChart:hover

{

opacity: 1.0;

}

That adds a rounded border and drop shadow to the chart image, and dims it unless the mouse is hovering over it.

Or to show a disabled BBjLineChart grayed out:

.BBjLineChart bbj-disabled

{
