Overview

Nutrela is a fresh, animated HTML5 template for healthy eateries, meal plan services and juice bars. Signika headlines and Open Sans text keep it bright and easy to read. Underneath, it runs real nutrition logic. Every calorie is worked out from the macros, and a bowl builder redraws the bowl with each choice. Weekly plans are priced by the meal, and delivery days follow each zone's cut-off. It ships with light and dark mode and WebGL layers - leaf veins growing in from the edges and a leaf breathing in light in the footer.

What’s included

• 31 HTML pages, 3 unique home page designs
• Light and dark mode on one switch, remembered between visits, with no flash on load

Getting Started

Thank you for choosing Nutrela. Follow the steps below to get your site live.

1. Open locally

Unzip the package and open nutrela/index.html in any modern browser (Chrome, Firefox, Edge, Safari). No build tools or server are required — every engine on the site works straight from the files.

2. Deploy to a server

Upload the contents of the nutrela/ folder to your hosting with an FTP client (such as FileZilla) or your hosting control panel. Open your domain and the template loads at once.

3. Customise

Custom styles live in assets/css/style.css and assets/css/responsive.css. Colours and fonts are CSS variables — see Colors & Fonts. Prices, hours and items live in one data block in assets/js/main.js (module 09, Nutrela Data) — see JavaScript Guide.

Colors & Fonts

The design is driven by CSS variables declared at the top of style.css. Change a token once and every section, button and card updates.

Fonts

Open Sans and Signika are loaded from Google Fonts in the <head> of every page. To change a font, replace the Google Fonts link and the font variables in style.css.

Light & Dark Mode

Every header (and the mobile menu) has a theme switch. The choice is saved in the browser under the key nutrela-theme and applied by a one-line script in the <head> before the page paints, so a visitor never sees a flash. The switch sets data-theme on the <html> tag.

• Tokens — the other theme’s colours sit in their own [data-theme] block right after :root in style.css. Change a colour there.
• WebGL layers — the layers read their colours from CSS custom properties (--gl-1 to --gl-3, --gl-alpha), so a theme change repaints them.
• Start in the other theme — add data-theme="dark" to a page’s <html> tag; the switch still works and is still remembered.

JavaScript Guide

All custom behaviour lives in assets/js/main.js, split into numbered modules listed in the index at the top of the file. Plugins are in assets/js/plugins/ and load before it. Module 09 (Nutrela Data) is the one data block the pages and engines read: change a price, an hour or an item there and every page that shows it follows.

Images

The package ships with placeholder images at their real dimensions. Replace them with your own photos using the same file names, or update the src attributes. Images are grouped inside assets/img/:

Contact Form

The contact form posts to sendmail.php, a lightweight AJAX mail handler; the success or error message appears under the button without a reload. The other forms on the site are demo forms: they confirm on screen and are ready to connect to your own systems.

1. Set your email address

$email = 'example@example.com';

2. Upload to a PHP host

The form needs a server with PHP mail() support (virtually every shared host). It will not send from your own computer.

3. Optional: enable Google reCAPTCHA v3

Invisible reCAPTCHA v3 is built into the handler and stays dormant until the form sends a token. Create v3 keys in the reCAPTCHA admin console, replace YOUR_RECAPTCHA_V3_SECRET_KEY in sendmail.php, and load the reCAPTCHA script with your site key on the contact page.
