How is text-shadow different from box-shadow?▾
text-shadow applies to the rendered letterforms only, tracing the visible strokes of each character. box-shadow applies to the element's rectangular border box. text-shadow has no inset or spread parameters — only x-offset, y-offset, blur, and color.
Can I use text-shadow to create an outline effect?▾
A rough outline is possible by stacking four 1px shadows in each cardinal direction: 1px 0, -1px 0, 0 1px, 0 -1px in the same color. For crisp outlines the CSS paint-order and -webkit-text-stroke properties produce cleaner results, especially at smaller sizes.
How do I make a glowing neon text style?▾
Set both offsets to 0 and use a saturated color with a blur of 8–20px. Adding two layers — a tighter blur (4–6px) at higher opacity and a wider blur (16–20px) at lower opacity — creates a more convincing glow gradient. Keep the text itself the lightest element in the composition.
Does text-shadow work on emoji and icon fonts?▾
text-shadow applies to any text-rendered glyph including emoji and icon fonts like Font Awesome. Results vary by rendering engine since emoji are sometimes rendered as bitmap images rather than vector glyphs, which may reduce shadow precision on some platforms.
Will too many shadow layers slow down rendering?▾
Multiple text-shadow layers do increase paint time, particularly on long paragraphs or when combined with font-smoothing. For body text keep layers to one or zero. For headings or short display text, two or three layers are generally fine on modern hardware.
How do I make shadows readable on body copy?▾
Keep blur under 3px, use a low alpha (0.3–0.5), and apply the shadow in the opposite direction of your heading shadow for consistency. Subtle depth is enough for body legibility — aggressive shadows on small text reduce readability rather than improving it.
Can I animate text-shadow with transitions?▾
Yes. text-shadow is animatable with CSS transitions and @keyframes. Transitioning from no shadow to a glow effect works well for interactive highlights. Keep animated blur values modest to avoid layout thrashing on large text blocks.
Does the order of stacked shadows change the result?▾
Yes. text-shadow layers paint front to back, so the first value in the comma list renders on top. If you have a tight opaque shadow and a wide glow, putting the opaque shadow first keeps it visible above the glow layer rather than buried beneath it.
