Start with basic HTML structure and CSS setup, then progress through setting up the border foundation and implementing techniques to fake a transparent background. Add outer glow effects using CSS properties, followed by creating inner glow elements to enhance the visual depth. Fine-tune blur values for optimal appearance and organize your code using custom CSS properties for better maintainability. Explore techniques for flipping the effect to different sides and improve the gradient customization for more dynamic results. Master two different approaches to animating the gradient and glow effects - first by changing colors dynamically, then discover a simpler animation method. Access the complete CodePen implementation and reference Google's original AI Mode design throughout the 30-minute tutorial that covers everything from basic setup to advanced animation techniques.
