CodeKitHubWhat Is This Tool?
This tool layers multiple blurred text-shadow values in your chosen glow color, at increasing blur radii, to recreate the soft glow of a neon sign.
Adjust the intensity slider to control how many glow layers are stacked, from a subtle glow to a strong, bright effect.
A live preview on a dark background updates instantly as you type or adjust any setting, so you can fine-tune the glow before copying the CSS.
Why Use It?
- You're building a landing page for a nightclub or bar event and a flat colored heading isn't selling the vibe — a neon glow on the headline signals "nightlife" the instant the page loads, before a visitor reads a word of copy.
- You're theming a portfolio site around a synthwave or cyberpunk aesthetic and need the hero text to actually glow, not just look like pink text on a dark background — the layered text-shadow is what sells the illusion.
- You're building an "OPEN" or "WELCOME" style badge for a virtual storefront and want it to read like an actual neon sign rather than a flat SVG icon, since the glow layers respond to real CSS rather than a static image.
- You want to compare a tight, subtle glow against a blown-out, maximum-intensity one before deciding which fits your brand — sliding the intensity setting shows you both without writing the shadow values by hand.
- 100% local: the CSS is generated entirely in your browser, with nothing sent to a server.
How to Use
- Type the text you want to glow.
- Pick a glow color and a background color that suits your design.
- Adjust the intensity slider to control how strong the glow effect looks.
- Click "Copy" to copy the generated CSS code and paste it into your stylesheet.
Example
Input
Text: "NEON", Glow Color: pink, Intensity: 3Output
color: #ffffff;
background: #0a0a12;
text-shadow: 0 0 2px #ff2ec4, 0 0 4px #ff2ec4, 0 0 8px #ff2ec4, 0 0 16px #ff2ec4;The generated CSS sets white text on a dark background with multiple stacked, blurred text-shadow layers in the chosen glow color.
How the neon glow effect works
The glow is built from several text-shadow layers in the same color, each with a larger blur radius than the last.
| Layer | Blur Radius | Effect |
|---|---|---|
| 1st | 2px | Tight inner glow close to the letters |
| 2nd | 4px | Slightly wider glow |
| 3rd | 8px | Soft mid-range glow |
| 4th | 16px | Wide outer glow |
| 5th | 24px | Broad ambient glow at max intensity |

Choosing a glow color for the right mood
- Pink and magenta glows read as classic 80s retro or synthwave — the most common choice for nightlife and arcade-themed designs.
- Cyan and blue glows lean more futuristic or tech-focused, common in cyberpunk and sci-fi UI mockups.
- Green glows evoke a hacker or terminal aesthetic, especially when paired with a monospace font.
- Warm amber or orange glows feel closer to a traditional neon bar sign than the cooler synthwave colors, useful for restaurant or bar branding that wants a vintage feel rather than a futuristic one.
Frequently Asked Questions
Why does the text need to be white for the glow to look right?
Neon glows work best with a bright, near-white text color since the colored glow comes entirely from the text-shadow layers — a dark or saturated text color would compete with the glow instead of letting it stand out.
Why does the effect need a dark background?
Like real neon signs, the glow effect is far more visible against a dark background. On a light background, the glow tends to wash out and become hard to see.
What does the intensity slider actually change?
It controls how many blurred text-shadow layers are stacked, from a single tight glow at low intensity to five layered glows with a wider spread at maximum intensity.
Does this tool save or track what I type?
No. The CSS is generated entirely in your browser — nothing is sent to or stored on a server.
Will this work in all browsers?
Yes — text-shadow with multiple comma-separated values has excellent support across all modern browsers, including Chrome, Firefox, Safari, and Edge.
Can I animate the glow to flicker like a real neon sign?
The generated CSS is a static glow, but you can extend it yourself with a CSS @keyframes animation that toggles the text-shadow's opacity or intensity between two states — the tool gives you the base glow values to animate from.
Will the glow still look right on a light or white background?
No — the effect depends heavily on contrast against a dark background, which is why the tool includes a background-color field alongside the text color. If you need the same headline on a light section of your page, keep it plain there and reserve the neon version for a dark section or card.
Does this affect page performance if I use it on a lot of text?
Text-shadow is a relatively lightweight CSS property, so a handful of glowing headings won't noticeably affect performance. Applying five stacked shadow layers to a large block of body text isn't recommended for readability, though, regardless of performance.
Can I use a different glow color for each word in a heading?
The tool generates one glow color per generation, but you can wrap different words in separate <span> tags with their own text-shadow value (generate one color, copy the CSS, then repeat for the second color) to get a multi-color glow effect.
Does the generated CSS work the same in dark mode and light mode toggles?
The neon effect is designed around a dark background by nature, so if your site supports a light/dark toggle, it's best to only apply the glow styling within your dark-mode CSS rather than trying to make it work on both themes.
