Alright, I need to create a production-ready HTML calculator for plantation shutters cost. The user has provided detailed requirements, so I’ll start by breaking down each part.
First, the calculator must be a single HTML file with embedded CSS and JavaScript. I’ll structure the HTML with a header, main content, and sections for the calculator and article. The design needs to be professional with specific colors and a single-column layout for responsiveness.
Next, the calculator inputs. I’ll include fields for the number of windows, average window size, shutter type, and paint color. Each input will be wrapped in an .input-group for styling. I’ll add helper text and error messages below each input for inline validation. The JavaScript will handle real-time calculations and validation, ensuring all inputs are valid numbers.
For the results, I’ll display the total cost prominently with intermediate values like cost per shutter and labor cost. The calculator will update results in real-time and include a Reset button to restore defaults. I’ll also add a Copy Results button using navigator.clipboard.
The article section must be SEO-optimized with specific sections like definition, formula explanation, examples, and FAQs. I’ll ensure the primary keyword density is met and include internal links where appropriate. The content should be detailed, addressing all aspects of plantation shutters cost calculation.
I’ll create a table showing cost breakdown by shutter type and a dynamic chart using SVG to visualize costs. The table will be responsive with horizontal scrolling on mobile, and the chart will adjust width for different screens.
Finally, I’ll ensure all code adheres to strict requirements: using var, inline onclick events, and no external libraries. The JavaScript will handle all calculations, validation, and dynamic updates. The CSS will be embedded, ensuring a clean, professional look with proper spacing and shadows.
I’ll test each part to make sure inputs validate correctly, results update dynamically, and the design is responsive. Once everything works as expected, I’ll compile the complete HTML file as the final output.
