Fixing The Overlapping Button Issue On Open Collective

Understanding the Problem: The Overlapping Button on Small Screens

Navigating the world of online fundraising and community support platforms, user experience is paramount. One common issue that can significantly impact the user's journey, particularly for those accessing the platform on smaller screens like mobile phones, is the overlapping of interface elements. In the context of Open Collective, a popular platform for funding and managing open-source projects and communities, this issue manifests specifically with the "Back this Collective" button. When a user clicks this button on a small-screen device to contribute to a collective, a modal (a pop-up window) is designed to appear, allowing the user to select a contribution amount and payment method. However, due to a design or coding oversight, the background "Back this Collective" button remains partially visible, overlapping the content of the modal. This overlap can obscure crucial elements within the modal, such as input fields, buttons, and informational text, making it difficult or even impossible for users to complete their intended action—backing the collective. This breakdown in the user interface can lead to frustration, confusion, and, ultimately, a decrease in contributions. Addressing this overlapping button issue is therefore not just a matter of aesthetic improvement but a crucial step in ensuring that the platform remains user-friendly, accessible, and effective in its primary function: facilitating the flow of financial support to valuable projects and communities. This directly impacts the platform's usability on mobile devices, which are a very popular way to access the internet nowadays. The core problem revolves around how the modal, designed to capture user input, interacts with the existing elements of the webpage. The design flaw allows the button to remain visible, obstructing the modal's contents.

Steps to Reproduce the Overlap

To thoroughly understand and address the overlapping issue, it's essential to outline the specific steps that replicate the problem. This clear understanding allows developers and designers to effectively test and validate the proposed solutions. The process is straightforward, allowing anyone to verify the presence of the issue and the impact it has on the user experience. By following these steps, we can ensure that the solution is robust and effectively eliminates the overlap, thus improving the overall usability of the platform. Here is a detailed breakdown of how to reproduce the overlapping button problem:

1. Access a Collective Page: Begin by navigating to any collective page on Open Collective. For example, you can visit a project page of your favorite open-source project or any other collective listed on the platform.
2. Simulate a Small Screen: Since the issue is most noticeable on small screens, you need to simulate a mobile device or a narrow browser window. You can do this by:
   • Resizing the Browser Window: If you're using a desktop computer, resize your browser window to a narrow width. A width of around 375 pixels is a good starting point to simulate a mobile screen.
   • Using Device Emulation (Developer Tools): Most modern web browsers, such as Chrome, Firefox, and Safari, have developer tools that allow you to emulate different devices. Open the developer tools (usually by pressing F12 or right-clicking on the page and selecting "Inspect") and use the device emulation feature to simulate a mobile device like an iPhone or Android phone.
3. Click the "Back this Collective" Button: Locate the "Back this Collective" button on the collective page and click it. This action should trigger the modal to open.
4. Observe the Overlap: Once the modal opens, carefully observe the interface. Look for any overlap between the modal's content and the "Back this Collective" button in the background. The button might partially obscure elements within the modal, such as text fields, buttons, or informational text.

By following these steps, anyone can easily reproduce the issue and see the impact it has on the user interface. This is a critical step in diagnosing the problem and verifying that proposed solutions effectively address the overlap.

Expected Behavior vs. Actual Behavior: A Comparison

To thoroughly understand the nature of the overlapping button issue, it's essential to compare the expected behavior of the platform with the actual behavior observed by users. This comparison highlights the discrepancies and clarifies the impact on the user experience. By clearly defining both the expected and actual behaviors, developers and designers can create targeted solutions that address the specific issues and improve the overall usability of the platform. The objective is to ensure that the user interface functions as intended and provides a seamless and intuitive experience for all users. The following details the expected and actual behaviors:

Expected Behavior

• Modal Presentation: When a user clicks the "Back this Collective" button, a modal window should appear on top of the existing content. This modal should act as a self-contained unit, clearly separate from the rest of the page. The modal's background should ideally have a dimmed or blurred overlay to further emphasize its presence and guide the user's focus.
• Background Interaction: The background content, including the "Back this Collective" button, should be fully hidden, disabled, or visually de-emphasized while the modal is open. The user should not be able to interact with the background elements while the modal is active, ensuring that their attention is directed solely towards the modal's contents.
• Clear and Unobstructed Content: All elements within the modal, such as input fields, buttons, and informational text, should be fully visible and easily accessible. There should be no overlap or obstruction from any background elements.

Actual Behavior

• Overlapping Elements: The actual behavior deviates significantly from the expected behavior. The "Back this Collective" button remains partially visible in the background, overlapping the content of the modal.
• Obstructed Content: The overlap can obscure critical elements within the modal, making it difficult for users to see and interact with input fields, buttons, or informational text. This obstruction directly impacts the user's ability to complete their desired action of backing the collective.
• Cluttered Interface: The overlapping of elements creates a cluttered and confusing interface. Users may find it difficult to understand which elements are interactive and which are not. This clutter can lead to frustration and a poor user experience.
• Interaction Issues: Due to the overlap, users might unintentionally click the background button instead of the intended modal elements. This can lead to unexpected behavior and further confusion.

Possible Solutions: Fixing the Overlapping Button Problem

The overlapping button issue on Open Collective can be addressed through several technical approaches, each with its own advantages and considerations. These solutions involve adjustments to the CSS (Cascading Style Sheets) and HTML (HyperText Markup Language) structure to ensure the modal window properly overlays the background content. The primary goal is to hide or disable the background button, and prevent it from interfering with the user's interaction with the modal. Here are some possible solutions:

CSS-Based Solutions

1. Z-Index Adjustment: The z-index property in CSS controls the stacking order of elements. By assigning a higher z-index value to the modal than the "Back this Collective" button, you can ensure that the modal always appears on top. For example, you might set the z-index of the modal to 1000 and the button's z-index to a lower value, such as 1. The specific z-index values may need adjustment based on other elements present on the page. This approach is simple and effective if the button is the only element causing the overlap. The modal’s z-index will need to be higher than that of the "Back this Collective" button.
2. Overlay with Dimming: Create an overlay element (a <div> element) that covers the entire background of the page when the modal is open. This overlay should have a semi-transparent background color (e.g., rgba(0, 0, 0, 0.5)) to dim the background and focus the user's attention on the modal. The overlay should be positioned absolutely or fixed to cover the entire viewport, and its z-index should be between the background elements and the modal. This ensures that the button is covered. The overlay can also be used to disable pointer events on the background, preventing any accidental clicks on the button. This approach is more robust because it ensures that all background elements are covered, not just the button.

HTML/JavaScript Solutions

1. Hide the Button: When the modal is opened, use JavaScript to hide the "Back this Collective" button from the DOM (Document Object Model). This can be achieved by setting the display property of the button to none or using the visibility: hidden; property. When the modal is closed, restore the button's visibility. This is a foolproof way to prevent the overlap. The downside is that it involves writing JavaScript code.
2. Disable the Button: Alternatively, you can disable the button instead of hiding it. Add the disabled attribute to the button when the modal is open and remove it when the modal is closed. This will prevent the button from being clicked, while still keeping it visible (though grayed out). This approach might be useful if you want to provide visual feedback to the user that the button is temporarily unavailable.

Combining Approaches

The most effective solution might involve a combination of these approaches. For example, you could use a CSS z-index adjustment along with an overlay to dim the background and disable pointer events. This combination provides a robust solution that addresses both the visual overlap and potential interaction issues.

Device, Browser, and Platform Information

Identifying the specific devices, browsers, and operating systems affected by the overlapping button issue is crucial for targeted testing and effective debugging. The issue might manifest differently across various platforms, so gathering this information allows developers to prioritize their efforts and ensure a consistent user experience. This detailed information will help in replicating the issue, identifying the root cause, and confirming the effectiveness of proposed solutions. The following information helps to paint a clear picture of the environment in which the issue occurs:

• Device: Include the specific device type, such as an iPhone 12, Samsung Galaxy S21, or any other mobile device. Alternatively, you can mention the use of a desktop computer with a specific browser and screen resolution to simulate a small-screen environment.
• Browser: Specify the web browser used, such as Safari, Chrome, Firefox, or Edge. Include the browser version number to ensure compatibility across different browser versions.
• Operating System: Indicate the operating system of the device, such as iOS 16, Android 12, or Windows 11. Knowing the operating system helps identify any platform-specific issues.
• Open Collective Version: If possible, include the version of Open Collective you are using. This information helps developers track changes and determine if the issue is specific to a particular version of the platform.

Why This Matters: The Importance of a Clean User Interface
