Styling FX Buttons with CSS

Styling FX Buttons with CSS


A number of people have asked me recently can I create this look or that look using CSS in JavaFX. Or they have said that you could never do that! So I thought I would do a little experiment and try recreating a bunch of common button styles purely using CSS. So without further ado, here is the result:


All of these are mostly created with multiple background fill layers each with a gradient. Then there is a little font tweaking and some subtle effects. So for example all you need to make a JavaFX button look like a Windows 7 button is:
#windows7-default {
    -fx-background-color:
        #3c7fb1,
        linear-gradient(#fafdfe, #e8f5fc),
        linear-gradient(#eaf6fd 0%, #d9f0fc 49%, #bee6fd 50%, #a7d9f5 100%);
    -fx-background-insets: 0,1,2;
    -fx-background-radius: 3,2,1;
    -fx-padding: 3 30 3 30;
    -fx-text-fill: black;
    -fx-font-size: 14px;
}
The first line defines the 3 background fills, first is solid color and the other two are linear gradients. The background-insets offsets the backgrounds so they do not 100% paint over each other and the second background is 1px in from the outside and the 3rd background is 2px in from the outside of the button. The background-radius us setting the corner radius�s of the 3 backgrounds getting smaller as the backgrounds move in, this makes the gap between the borders a consistent 1 pixel all the way around. Padding adds extra space around the text to make the button bigger by default. Then the last two lines set the text color and size. That is all there is too it.
I have not included styles for the pressed, over and focused states of all the buttons but they can all be easily added in a similar way. I have included a over and pressed state for the �Record Sales� button as a example.
You can download the complete Netbeans project with all the code here.

Here is the CSS code of all the button styles you see above:
