Why doesn't this image sprite menu display properly, and why aren't the links working?

fixed the issue. Will look into that further Hum - maybe you should try setting the links (.menu a) to display: block to have the links working properly. Otherwise the link won't stretch to use the specified size, links are inline elements (correct me if I'm wrong, didn't test it).

Working on Creating Image Gallery in JavaFX. not able to display image properly
Date : March 29 2020, 07:55 AM
like below fixes the issue You need to create a TilePane and add the ImageView's to it. You can have a ScrollPane if needed. A complete example with double click to create a fullscreen preview is shown below. You can of course do necessary changes for creating a FXML :) import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import javafx.application.Application;
import javafx.event.EventHandler;
import javafx.geometry.Insets;
import javafx.scene.Scene;
import javafx.scene.control.ScrollPane;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.input.MouseButton;
import javafx.scene.input.MouseEvent;
import javafx.scene.layout.BorderPane;
import javafx.scene.layout.TilePane;
import javafx.scene.paint.Color;
import javafx.stage.Screen;
import javafx.stage.Stage;
public class ImageGallery extends Application {
Stage stage;
@Override
public void start(Stage primaryStage) throws Exception {
stage = primaryStage;
ScrollPane root = new ScrollPane();
TilePane tile = new TilePane();
root.setStyle("-fx-background-color: DAE6F3;");
tile.setPadding(new Insets(15, 15, 15, 15));
tile.setHgap(15);
String path = "/home/ubuntu/eclipse with liferay/Desktop/imagetest/";
File folder = new File(path);
File[] listOfFiles = folder.listFiles();
for (final File file : listOfFiles) {
ImageView imageView;
imageView = createImageView(file);
tile.getChildren().addAll(imageView);
}
root.setHbarPolicy(ScrollPane.ScrollBarPolicy.NEVER); // Horizontal
root.setVbarPolicy(ScrollPane.ScrollBarPolicy.AS_NEEDED); // Vertical scroll bar
root.setFitToWidth(true);
root.setContent(tile);
primaryStage.setWidth(Screen.getPrimary().getVisualBounds().getWidth());
primaryStage.setHeight(Screen.getPrimary().getVisualBounds()
.getHeight());
Scene scene = new Scene(root);
primaryStage.setScene(scene);
primaryStage.show();
}
private ImageView createImageView(final File imageFile) {
// DEFAULT_THUMBNAIL_WIDTH is a constant you need to define
// The last two arguments are: preserveRatio, and use smooth (slower)
// resizing
ImageView imageView = null;
try {
final Image image = new Image(new FileInputStream(imageFile), 150, 0, true,
true);
imageView = new ImageView(image);
imageView.setFitWidth(150);
imageView.setOnMouseClicked(new EventHandler<MouseEvent>() {
@Override
public void handle(MouseEvent mouseEvent) {
if(mouseEvent.getButton().equals(MouseButton.PRIMARY)){
if(mouseEvent.getClickCount() == 2){
try {
BorderPane borderPane = new BorderPane();
ImageView imageView = new ImageView();
Image image = new Image(new FileInputStream(imageFile));
imageView.setImage(image);
imageView.setStyle("-fx-background-color: BLACK");
imageView.setFitHeight(stage.getHeight() - 10);
imageView.setPreserveRatio(true);
imageView.setSmooth(true);
imageView.setCache(true);
borderPane.setCenter(imageView);
borderPane.setStyle("-fx-background-color: BLACK");
Stage newStage = new Stage();
newStage.setWidth(stage.getWidth());
newStage.setHeight(stage.getHeight());
newStage.setTitle(imageFile.getName());
Scene scene = new Scene(borderPane,Color.BLACK);
newStage.setScene(scene);
newStage.show();
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
}
}
});
} catch (FileNotFoundException ex) {
ex.printStackTrace();
}
return imageView;
}
public static void main(String[] args) {
launch(args);

'Hover image display image' CSS is not working properly
Date : March 29 2020, 07:55 AM
To fix this issue Use background-size property, as you are setting a background-image property to a:before element and the size of the background image is 256x256. But you've defined the width & height of the a:before element to 50px, so the size of the background image should also be 50px. Just use: a:hover:before {
background-size: 50px; /* as you have 'width' and 'height' defined as 50px each */
}
a {
position: relative;
display: inline-block;
}
a:hover:before {
content: '';
display: block;
background-image:url('http://i.imgur.com/fGAbTOj.png');
width: 50px;
height: 50px;
background-size: 50px;
position: absolute;
top: 0;
left: 0;
}
