How to set image size in JTextPane with HTML and CSS (Java, Swing)?

I want to insert an image (say - a formula compiled from LaTeX) into JTextPane, using HTML+CSS for text markup, manually setting it's size. I tried like here

import java.awt.Dimension;
import javax.swing.JFrame;
import javax.swing.JTextPane;


public class App extends JFrame {

    private void run() {
        setSize(new Dimension(320, 240));
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        JTextPane pane = new JTextPane();
        pane.setContentType("text/html");
        String imageUrl = getClass()
                              .getClassLoader()
                              .getResource("resources/img.jpg");
        pane.setText(
                "<html>"+
                    "<head> <style>"+
                            // CSS works perfectly for text,
                            ".text { color: red; font-family: \"Times New Roman\"; }"+
                            // but not for images
                            ".pic { width: 250px; }"+
                    "</style> </head>"+
                    "<body>"+
                        "<p class=\"text\"> Aaaa. </p>"+
                        "<img class=\"pic\" src=\""+imageUrl+"\" />"+
                    "</body>"+
                "</html>"
            );
        
        getContentPane().add(pane);
        setVisible(true);
    };

    public App() {
        super("Test HTML+CSS");
    }

    public static void main(String[] args) {
        App app = new App();
        app.run();
    }
}

For some reason JTextPane works perfectly with text styles, but ignores CSS notations for pictures. Is there any way to handle this out or I'm just wasting time?

Solution

As Gilbert Le Blank mentioned in the comment, the width block shall be in <img> statement. So the HTML string should look like this:

<html>
  <body>
    <p color="red"> Aaaa. </p>
    <img width="250" src="/path/to/Image" />
  </body>
</html>
