<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Iosevka Fixed SS16"">No, it cannot. This (and other methods that add a text segment), while adding the style names to the underlying nodes, cannot style the background. The reason is these methods
add the Text instances, and the Text class does not have the background property. So even if your CSS style specifies the background properties, they will be ignored.<o:p></o:p></span></p>

<p class="MsoNormal" style="margin-bottom:12.0pt"><span style="font-size:12.0pt">I've read your comments on the issue and was actually in the process of writing to you when I received your message.
<br>
Let me clarify a critically important point.<br>
<br>
Currently, to style segment text using CSS style classes, we use this method:<br>
RichParagraph.Builder.addWithStyleNames(String text, String... css) - ONE METHOD FOR ALL STYLE CLASSES.<br>
<br>
If I understand correctly (and I might be wrong!), you're suggesting using a DIFFERENT method for background color styling:<br>
RichParagraph.Builder#addHighlight(int start, int end, String... styles).<br>
<br>
Could you please confirm whether RichParagraph.Builder.addWithStyleNames(String text, String... css) can also be used for background coloring?<br>
<br>
For example, we know that user wants to add style classes "foo" and "bar" to a text from from 5 to 20. We do not know IF THESE STYLES
<br>
SET BACKGROUND COLOR. Or should we ask an user to name a class this way - "foo-bg"?
<br>
<br>

That doesn’t work for me. As I mentioned before, I’m working with two CodeArea implementations - JFX and RTFX,
<br>
and CSS is the common styling mechanism. I can’t use code for one and CSS for the other.

Well, technically I could, but it just wouldn’t make any sense.<br>

<b>Subject: </b>CodeArea: -fx-background-color doesn't work.</span><o:p></o:p></p>

<p class="MsoNormal"><span style="font-size:11.0pt">For styling CodeArea, I use exclusively style classes, and this is the foundation of my entire architecture.<br>
Today I tried to implement search highlighting (via background color), but it didn't work. Below is my test code.<br>
<br>
Can anyone tell me how to set the background color using CSS? For example, in RichTextFX's CodeArea,<br>
they have -rtfx-background-color.<br>
<br>
public class JfxCodeArea extends Application {<br>
<br>
@Override<br>
public void start(Stage primaryStage) throws Exception {<br>
String text = """<br>

ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco<br>
laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit<br>
in voluptate velit esse cillum dolore eu fugiat nulla pariatur.<br>
""";<br>
<br>
String css = """<br>
.test {<br>
-fx-font-weight: bold;<br>
-fx-fill: red;<br>
-fx-background-color: green;<br>
}<br>
<br>
""";<br>
String data = <span class="MsoHyperlink">"data:text/css;base64,"</span> + Base64.getEncoder().encodeToString(css.getBytes(StandardCharsets.UTF_8));<br>
<br>
CodeArea codeArea = new CodeArea();<br>
codeArea.getStylesheets().add(data);<br>
<br>
codeArea.setSyntaxDecorator(new SyntaxDecorator() {<br>
@Override<br>
public RichParagraph createRichParagraph(CodeTextModel model, int index) {<br>
var builder = RichParagraph.builder();<br>
builder.addWithStyleNames(model.getPlainText(index), "test");<br>
return builder.build();<br>
}<br>
<br>
@Override<br>
public void handleChange(CodeTextModel m, TextPos start, TextPos end, int charsTop, int linesAdded, int charsBottom) {<br>
<br>
}<br>
});<br>
<br>
VBox.setVgrow(codeArea, Priority.ALWAYS);<br>
var button = new Button("Go!");<br>
button.setOnAction(e -> codeArea.setText(text));<br>
VBox root = new VBox(codeArea, button);<br>
Scene scene = new Scene(root, 600, 200);<br>
primaryStage.setScene(scene);<br>
primaryStage.show();<br>
<br>
}<br>
<br>
public static void main(String[] args) {<br>
launch(args);<br>
}<br>
}<br>
