Creating a Responsive Card Layout in OutSystems That Rearranges on Mobile

Creating a responsive card layout in OutSystems is essential to ensure that your web applications are well-adapted for different screen sizes, particularly mobile devices. This guide provides an extensive step-by-step approach to building a responsive card layout that dynamically rearranges based on the user's device.

Prerequisites

• An OutSystems account with a project ready for implementing responsive design.
• Basic understanding of OutSystems UI elements and layout properties.
• Familiarity with HTML/CSS can be beneficial for deeper customizations.

Understanding Responsive Design in OutSystems

• Responsive design automatically adjusts your application's layout based on the device's screen size and orientation.
• OutSystems provides built-in support for responsive design using CSS Flexbox and Grid properties, which you can leverage to create adaptive layouts.

Setting Up Your Card Layout in OutSystems

• Open your OutSystems project and navigate to the screen where you want to add the responsive card layout.
• Drag and drop a Container widget onto your screen; this will serve as the wrapper for your cards.
• Inside this container, you can add another Container widget, or directly add the Card widget if available (based on your template).
• Repeat the card addition process depending on how many cards you desire within this layout.

Applying Styles for Responsiveness

• Click on the parent Container (the card wrapper) and navigate to the Styles tab in the Properties panel.
• Set the display property to flex or grid to enable responsive behavior. Here's how you can proceed with Flexbox:
• Use CSS classes or directly set the styles:

.container {
  display: flex;
  flex-wrap: wrap; /_ Enables wrapping of cards on smaller screens _/
  justify-content: space-between; /_ Distributes space between cards _/
}
.card {
  flex: 1 1 200px; /_ Specifies the flex growth, shrink, and base width _/
  margin: 10px; /_ Adds spacing between cards _/
}
    

Using Media Queries for Enhanced Mobile Responsiveness

• Create a style sheet or directly use the Styles tab to include media queries, adjusting card layout specifically for mobile devices.
• Example code snippet for a media query:

@media (max-width: 768px) { /_ Targets tablet and smaller screens _/
  .container {
    justify-content: center; /_ Centers cards on smaller screens _/
  }
  .card {
    flex: 1 1 100%; /_ Takes full width on small screens _/
  }
}
  

• Adjust these styles to match the number of cards and desired appearance on various screen sizes.

Testing Your Responsive Layout

• Use the OutSystems preview feature to test your responsive layout on different devices.
• Resize your browser window to see how the cards realign themselves on smaller screens.
• Ensure responsiveness remains consistent across actual mobile devices to verify that user experience isn’t compromised.

Deploying Your Responsive Card Layout

• After ensuring that your responsive card layout functions as intended and appears well on various devices, you can proceed to deploy your app.
• Before full deployment, test the application in different environments to check performance and adaptability across devices.

By following these steps, you can successfully create a responsive card layout in OutSystems that automatically rearranges based on device dimensions. This approach enhances user experience by providing a seamless interface across different screens, ensuring the accessibility and usability of your application.
