I'll develop a fuel consumption calculator widget turnkey

I develop turnkey fuel consumption calculator widgets for automotive websites and blogs. Over several years working with automotive topics, I've created more than a dozen small interactive tools for dealer websites, auto parts stores, and travel blogs, and the trip cost calculator is one of the most popular: visitors like seeing immediately how much the road will cost.

The widget accepts trip distance and average fuel consumption of the vehicle per 100 kilometers, then instantly calculates the required fuel volume in liters and approximate trip cost at current fuel prices. I write clean code without heavy frameworks, so the widget loads quickly and doesn't hurt page speed metrics. I adjust the appearance to match the site's colors and fonts, and the block can be embedded with a single code snippet in WordPress, a custom CMS, or a regular static page.

By default, I add reasonable result rounding, a field for manual fuel price entry, and value verification so a visitor can't enter negative distance or zero fuel consumption. If needed, I can connect auto-updating fuel prices or add round-trip calculation.

What's included in the work:
— working calculator widget, tested on desktop and mobile
— clean HTML/CSS/JS without external dependencies
— design adaptation to the site's appearance
— source files and brief installation instructions
