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 BBjButton is implemented as a <div> element. It has two variants, .BBjButton.bbj-default, applied to any button with a control ID of 1, and .BBjButton.bbj-cancel, applied to any button with a control ID of 2. The BBjButton defines the following style names:

.BBjButton

.BBjButton.bbj-cancel

.BBjButton.bbj-default

.BBjButton.bbj-disabled

.BBjButton.bbj-focused

.BBjButton.bbj-transparent

There are many different options for styling the BBjButton. One simple choice would be to add rounded borders:

.BBjButton

{

  border-radius: 10px;  

}

Remarks


Mobile touch-oriented browsers (e.g. Mobile Safari in iOS, Chrome in Android) wait for 300 milliseconds after the user taps an element before generating a click event. This delay makes applications feel sluggish when the user tries to click on multiple buttons in rapid sequence, a process that can be common in applications like phone dialers. When the
FAST_TOUCH_CLICK !OPTIONS setting is set to TRUE, BUI buttons on iOS and Android report ON_BUTTON_PUSH immediately when the user touches and releases their finger from a button. This improves the responsiveness for those events, but introduces some side effects that the developer should be aware of. Because BUI is handling touch events on these buttons, normal double-tap and pinch-zoom gestures don't work. And because BUI is reporting the ON_BUTTON_PUSH event immediately, it appears in the event stream before the button reports gaining focus. Some applications are sensitive to precise sequence of events.
