Alright, I need to create a production-ready HTML calculator for the Euler function, also known as Euler’s totient function. The user has provided specific guidelines, so I’ll follow them step by step.
First, I’ll structure the HTML with a header, main content, and footer. The header will include the title and meta tags for SEO. The main content will have the calculator, followed by the SEO article. The footer will contain copyright information.
For the calculator, I’ll use a centered container with a max-width for readability. The input section will have a number field for the user to input an integer. I’ll include a reset button to restore default values and a copy results button. The results section will display the totient value and intermediate steps, along with a formula explanation.
Next, I’ll add a table to show the factors and their contributions to the totient function. This helps users understand the calculation process. I’ll ensure the table is responsive, especially on mobile devices.
The JavaScript part will handle the calculations. I’ll write a function to compute the totient using the formula φ(n) = n * product of (1 – 1/p) for each prime factor p. I’ll also include functions to check for prime factors and validate inputs. The results will update in real-time as the user changes the input.
For the SEO article, I’ll structure it into sections as specified: definition, formula explanation, examples, how to use the calculator, key factors, FAQs, and related tools. Each section will be detailed to provide comprehensive information and include relevant keywords for SEO.
I’ll ensure the article uses semantic HTML elements and that the content is optimized for search engines with proper keyword density and internal linking. The related tools section will include links to other calculators, enhancing the site’s internal navigation.
Styling will be done using embedded CSS, adhering to the specified color scheme and responsive design principles. I’ll make sure the layout is single-column, with proper padding and margins for readability on all devices.
Finally, I’ll test the calculator to ensure it works correctly, handles edge cases, and updates results dynamically. I’ll also verify that the article content is informative, well-structured, and optimized for SEO.
