This question explores CSS and addresses practical considerations related to: Why isn't my animation easing smoothly between keyframes?

If your animation isn't easing smoothly between keyframes, it might be due to the timing function used in your CSS animation. The timing function controls the acceleration of the animation, and choosing the right one can make transitions appear more natural. .my-animation { animation: slideIn 2s ease-in-out; } @keyframes slideIn { from { transform: translateX(-100%); } to { transform: translateX(0); } } ADDITIONAL COMMENT: The "ease-in-out" timing function starts the animation slowly, speeds up in the middle, and slows down again towards the end. Ensure your keyframes are correctly defined and that the animation duration is appropriate for the effect you want. Consider using "cubic-bezier" for custom easing if predefined options don't fit your needs. Check for any conflicting CSS rules that might affect the animation. ✅

      }
      to {
        transform: translateX(0);
      }
