Box Shadow Glow: Adds outer glow to HTML elements, commonly used for cards, buttons, and other components.
Text Shadow Glow: Adds glow to text, commonly used for headings and neon-style text.
Multi-layer Glow: Increase layers to stack multiple shadows with different blur radii for richer glow effects.
Glow is essentially a type of box-shadow or text-shadow with a large blur radius and zero offset. Regular shadows have large offsets and small blur, while glow has zero offset and large blur.
Use multiple layers with increasing blur radius and decreasing opacity. For example: layer 1 blur:10px opacity:0.8, layer 2 blur:20px opacity:0.4, layer 3 blur:40px opacity:0.2.
Large box-shadow areas can impact rendering performance, especially on mobile. Keep blur under 30px, layers under 3, and avoid using glow on many elements simultaneously.
box-shadow and text-shadow are well-supported in all modern browsers including Chrome, Firefox, Safari, and Edge. IE9+ partially supports box-shadow.
