text-shadow property. By layering multiple shadows with increasing blur radii and matching colors, you create the illusion of light radiating from the text. The innermost shadows are typically white or light-colored (simulating the hot core of a neon tube), while outer layers use the desired glow color with larger blur values to create the halo effect. No images or JavaScript are required—it's pure CSS and works in all modern browsers.text-shadow property is supported by all modern browsers including Chrome, Firefox, Safari, Edge, and Opera, as well as mobile browsers on iOS and Android. It has been part of the CSS specification since CSS2 (with widespread support since ~2010). Multiple shadow layers are also universally supported. CSS animations used for glow effects (pulse, flicker) work in all modern browsers. For older browsers like IE9 and below, the glow simply won't appear but the text remains fully readable.@keyframes can animate the text-shadow property to create pulse, flicker, or breathing effects. A pulse animation alternates between normal and intensified glow. A flicker effect uses multiple keyframe stops at irregular intervals to mimic the unstable nature of real neon lighting. A breathing effect smoothly oscillates the glow intensity. Note that animating text-shadow can be GPU-intensive on some devices, so use these effects sparingly and test performance, especially on mobile.text-shadow creates a glow directly around the glyph shapes of the text, following each letter's contours precisely. box-shadow creates a glow around the rectangular bounding box of an element. For typography, text-shadow produces a much more natural and appealing glow because it respects the actual letterforms. Box-shadow glow is better suited for buttons, cards, and container elements. Both can be combined for layered effects—for example, glowing text inside a glowing card.Apply the drop‑shadow() filter and compare it with box‑shadow.
