  • Visual real-time preview

  • Simple and intuitive interface
    The tool has a clean, straightforward interface with sliders and input fields that make it easy for beginners and experienced developers alike to create box-shadow effects without memorizing CSS syntax.
  • Free and browser-based
    The tool is completely free to use and runs entirely in the browser with no installation, sign-up, or downloads required, making it instantly accessible to anyone.
  • Quick code output
    The generator produces ready-to-use CSS box-shadow code that can be copied and pasted directly into a stylesheet, saving development time and reducing syntax errors.
  • Adjustable parameters
    Users can easily tweak key shadow properties such as horizontal offset, vertical offset, blur radius, spread radius, and color to fine-tune the exact shadow effect they need.

Possible disadvantages

  • Limited to single shadow
    The tool appears to only support generating a single box-shadow value at a time, whereas CSS allows multiple comma-separated shadows for more complex effects.
  • Minimal styling options
    The generator focuses solely on box-shadow and doesn't include related CSS properties like border-radius or background color adjustments that could help users visualize the shadow in a more realistic context.
  • No preset examples
    The tool lacks a library of pre-built shadow presets or templates that users could use as starting points, which would speed up the design process for common shadow styles.
  • Basic UI design
    The interface is quite minimal and could benefit from a more polished, modern design with better visual hierarchy and additional guidance or tooltips for less experienced users.
  • No export or save functionality
    There is no built-in way to save, bookmark, or export multiple shadow configurations for later comparison or use, so users must manually copy and store their generated values elsewhere.

Questions & Answers

As answered by people managing LoadCairn and CSS Box-Shadow Code Generator.

What makes your product unique?

LoadCairn's answer

Every calculator shows its formula, inputs and assumptions, with references to ASHRAE and NIST. Engineers can check the math instead of trusting a vendor tool that hides it.

Why should a person choose your product over its competitors?

LoadCairn's answer

Vendor calculators from APC, Eaton and Vertiv are tied to their own products and don't show their work. LoadCairn is vendor-neutral, free with no account, and covers power, cooling and facility metrics in one place. It also works offline in data halls with no signal.

How would you describe the primary audience of your product?

LoadCairn's answer

Critical facility engineers, data center technicians, facility managers, MEP consultants, data center project teams and students.

What's the story behind your product?

LoadCairn's answer

I've worked in data centers for 20 years. Most sizing still happens in old spreadsheets or vendor tools that won't show the math. I built LoadCairn so engineers have quick, transparent estimates they can defend in a design review.

Which are the primary technologies used for building your product?

LoadCairn's answer

A web app built on the Polsia platform. It installs on phone or laptop as a progressive web app (PWA) and works offline.

Who are some of the biggest customers of your product?

LoadCairn's answer

Not available at this thime.
