Calculator Widget — Add It to Your Website

Overview

What Calculator does

Calculator is an embeddable widget you drop into any website with a single snippet of code. Clean embeddable calculator with multiple modes. It runs in its own isolated frame, so it can never clash with your site's own styles or scripts, and it resizes itself to fit wherever you place it.

Calculator keeps itself up to date: once the snippet is on your page, everything it displays is driven from your myNaturevista dashboard. Change a setting there and your live site reflects it straight away, without editing a single line of code again.

You control how it looks and behaves from 5 settings — calculator type, let visitors switch between basic and scientific, theme, accent color and more. Pick the options that match your brand, save, and the change is live.

Like every widget in the myNaturevista tools & utilities collection, Calculator is built to be fast and unobtrusive: it loads asynchronously so it never blocks your page, works on phones and desktops alike, and can be added to as many of your pages as you want.

Features

What you get

Basic or scientific: trigonometry, logarithms, powers, roots and parentheses — you choose the default.
Fully configurable from your dashboard — no code changes needed.
Light or dark theme to match your site's design.
Lightweight and fast-loading — won't slow down your site.

Setup

How to add Calculator to your site

Three steps, about two minutes, no build tools.

1

Add the loader once

Paste a single <script> tag before your closing </body> tag. One loader powers every myNaturevista widget on the page, so you only ever add it once.
2

Place the widget

Drop a small <div> wherever Calculator should appear — inside a column, a section, a sidebar, anywhere. It takes the width it is given and sets its own height.
3

Configure it in the dashboard

Choose the theme and options that suit your site from the dashboard. Calculator picks them up on the next page load.

<!-- 1. Load the myNaturevista loader once per page -->

Agencies

Ship the same tested widget across every client site instead of rebuilding it each time.

FAQ

Calculator — frequently asked questions

How do I add the Calculator widget to my website?

Add the myNaturevista loader script once before your closing </body> tag, then place a <div> with your widget id, API key and instance id wherever Calculator should appear. That is the whole installation — it works on any platform that lets you paste HTML, including WordPress, Shopify, Squarespace, Webflow and hand-written sites.

Do I need to know how to code to use Calculator?

No. If you can paste a snippet of HTML into your site once, you are done. Everything after that — settings, content and styling — is handled from your myNaturevista dashboard, with no further code changes.

Can I customise how Calculator looks?

Yes. Calculator exposes 5 settings: calculator type, let visitors switch between basic and scientific, theme, accent color, show calculation history. Change them in the dashboard and your live site picks the new values up on the next page load.

Does Calculator work on mobile?

Yes. Calculator is responsive: it takes the width of the container you place it in and adjusts its layout and height for phones, tablets and desktops.

Will Calculator slow down my website?

No. The loader is asynchronous, so it never blocks your page from rendering, and the widget itself runs in an isolated frame that loads separately from your own content.

Can I use Calculator on more than one website?

Yes. Each website you own gets its own API key and its own configuration, so the same widget can show different settings and content on each domain.

Which plans include Calculator?

Calculator is available on the following plans: Free, Starter, Business, Enterprise. You can change plan at any time from your dashboard.
