Question: I am displaying some text in a JLabel. Basically I am generating that text dynamically, and then I apply some HTML tags (e.g., `BR` and `B`) to format the text. Finally I assign this formatted text to my JLabel.

Now I want my Jlabel to automatically wrap the text to the next line when it reaches the end of screen, like the "Word Wrap" feature in Note Pad.

How can I do that?

Answer: 
A width can be set for the `body` using HTML styles (CSS). This in turn will determine the number of lines to render and, from that, the preferred height of the label.

Setting the width in CSS avoids the need to compute where line breaks should occur in (or the best size of) the label.

```
import javax.swing.*;

public class FixedWidthLabel {

    public static void main(String[] srgs) {
        final String s = "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Aenean eu nulla urna. Donec sit amet risus nisl, a porta enim. Quisque luctus, ligula eu scelerisque gravida, tellus quam vestibulum urna, ut aliquet sapien purus sed erat. Pellentesque consequat vehicula magna, eu aliquam magna interdum porttitor. Class aptent taciti sociosqu ad litora torquent per conubia nostra, per inceptos himenaeos. Sed sollicitudin sapien non leo tempus lobortis. Morbi semper auctor ipsum, a semper quam elementum a. Aliquam eget sem metus.";
        final String html = "<html><body style='width: %1spx'>%1s";

        Runnable r = () -> {
            JOptionPane.showMessageDialog(
                    null, String.format(html, 200, s));
            JOptionPane.showMessageDialog(
                    null, String.format(html, 300, s));
        };
        SwingUtilities.invokeLater(r);
    }
}

```

Just thought I should post this for anyone searching the internet, as it was the tiny little mistake that cost me 30 minutes, but make sure you've *actually* wrapped the text in HTML. You may have thought you did and yet didn't. Check it, I forgot, and when I wrapped them in HTML it fixed it for me.

`JLabel label = new JLabel("Lorem ipsum long paragraph");` wrong.

`JLabel label = new JLabel("<html>Lorem ipsum long paragraph</html>");` correct!
