+title: 🟠 Content Projection Condition
+description: Challenge 58 is about conditional content projection in Angular
+author: thomas-laforge

+challengeNumber: 58

+
+## Information
+
+Content projection in Angular allows you to create flexible and reusable components by dynamically inserting content from a parent component using `<ng-content>`. However, debugging content projection issues can sometimes be tricky.
+
+In this challenge, we have a `CardComponent` that supports a small mode, which conditionally changes how the projected content is displayed. However, there is a bug: when `small` is `false`, the card does not render properly.
+
+Your task is to identify and fix this issue without adding `inputs` while ensuring that the intended behavior remains unchanged.
+
+## Statement
+
+Your goal is to fix the issue where the `CardComponent` does not render when `small` is `false`.
+
+## Steps to complete:
+
+- Analyze how the `small` property is used inside the template.
+- Identify why the content is not displayed when `small` is `false`.
+- Modify the component to ensure that both cases (`small` = `true` and `small` = `false`) work as expected, while keeping the same structure and behavior.
+- Ensure that no new `input` properties are introduced in the component.
+
+## Constraints
+
+- You must not add any new `input` properties.
+- The expected UI and behavior must remain unchanged.
+- The `@if` directive must be correctly handled to ensure content projection works.
+- Do not introduce additional services or state management solutions.
+- The fix should be minimal and focused on resolving the rendering issue.
