A glowing neon sign look is created with layered text-shadow values of increasing blur radius, all in the same bright color, which builds up the characteristic soft glow around each letter against a dark background.
Type your text, pick a glow color, and adjust the intensity slider to control how many shadow layers and how far the glow spreads, previewing live against a dark background that mimics a real neon sign's typical setting.
This works purely with the text-shadow CSS property — no images or extra markup needed — making it a lightweight way to add a striking neon-style heading to a dark-themed page or landing section.

Frequently asked questions
Why does this only look right on a dark background?
Neon glow effects rely on contrast against darkness to read convincingly, the same way real neon signs are most vivid at night — on a light background, the same shadow values look more like a fuzzy outline than a glow.
Does higher intensity always look better?
Not necessarily — very high intensity can start to look blurry or washed out rather than crisp; moderate settings often give the cleanest classic neon look.
