JavaFX-based UI objects can be styled using CSS files (similar to how HTML objects can be styled). Note that the CSS attribute names are normally different to those used to style HTML. However, most are just the equivalent for HTML with an added -fx- prefix.
Height And Width
Please note that the width and height properties of UI objects are read only (i.e. you cannot set them). They reflect the current ACTUAL width and height of the object. The width and height of an UI object maybe manipulated by setting the minWidth, prefWidth, maxWidth (ditto for height) properties.
CSS styling can be used by applying it to a JavaFX Scene object, using the following code within a .java file:
The background of JavaFX nodes can be styled using a variety of
A basic, single-tone colour can be applied to a JavaFX node with:
or by using hex:
You can also provide multiple values to the background colour property. The following code gives the node a button-like appearance:
-fx-background-color: -fx-shadow-highlight-color, -fx-outer-border, -fx-inner-border, -fx-body-color;
-fx-shadow-highlight-color and all the other values used above are predefined by JavaFX.
A colour gradient can be set with:
-fx-background-color: linear-gradient(to right, #000000, #FFFFFF);
You will probably want to choose something more subtle than a solid white to black gradient!
