I'll modify the design to remove the moving line and add more color emphasis on the selected tab, with a hover effect for non-selected tabs. Let's refine our unique tabs component.

In this refined version of the Tabs component, we've made the following changes to address your requests and create a more distinctive look:

1. Removed the moving line animation completely.
2. Added a bottom border (underline) only for the selected tab using the border-b-2 and border-primary classes.
3. Implemented a hover effect for non-selected tabs that shows a muted underline using hover:border-muted-foreground.
4. Enhanced the color emphasis on the selected tab by using the text-primary class and increasing the font weight with font-semibold.
5. Kept the overall minimalistic design while improving the visual feedback for user interactions.

The key changes in the styling include:

• Using border-b-2 border-transparent as a base for all tabs.
• Adding hover:text-foreground hover:border-muted-foreground for the hover effect on non-selected tabs.
• Styling the active tab with data-[state=active]:border-primary data-[state=active]:text-primary data-[state=active]:font-semibold.

This design maintains a clean and minimalistic look while providing clear visual cues for the selected tab and interactive elements. The use of primary color for the selected tab's underline and text creates a strong emphasis, and the hover effect on non-selected tabs improves the overall user experience.

You can further customize this design by adjusting the colors, spacing, or adding additional visual elements to suit your specific needs. For example, you could experiment with different transition effects or adjust the spacing between tabs for a more compact or spread-out look.

I'll modify our tabs component to include a sliding underline effect when switching between tabs. This will add a nice, smooth transition that enhances the user experience.

Let's update our refined tabs component to include this sliding effect:

In this updated version of the Tabs component, we've made the following changes to create a sliding underline effect:

1. Removed the static underline from individual tabs.
2. Added a motion.div element inside the TabsList to act as the sliding underline.
3. Used the useState and useRef hooks to track the active tab and its dimensions.
4. Implemented a useEffect hook to update the underline position and width when the active tab changes.
5. Utilized Framer Motion to animate the underline smoothly between tabs.

Key features of this implementation:

• The underline adapts to the width of each tab, ensuring it always matches the text length.
• The animation uses a spring effect for a natural, slightly bouncy feel.
• The component remains accessible, with proper ARIA attributes inherited from Radix UI.
• The design maintains its minimalistic look while adding a dynamic, interactive element.

This sliding underline effect provides a clear visual indication of the selected tab while adding a touch of interactivity and polish to the user interface. The smooth animation helps guide the user's eye to the newly selected tab, enhancing the overall user experience.

You can further customize this design by adjusting the animation parameters, underline thickness, or colors to match your specific design preferences. For example, you could experiment with different animation types or add subtle transitions to the tab text colors as well.
