Apply OmniCalculator-inspired UI and styles site-wide | Dev Logs

Date: 2026-01-15 15:30 Summary: Apply OmniCalculator-inspired UI and styles site-wide

[question] 参考 ：https://www.omnicalculator.com/的页面ui设计和样式，修改本项目的ui和样式

[try to solve] Implemented an OmniCalculator-like visual update across the site:

• Added a global stylesheet public/styles/omnicalc.css with color tokens, card, button, input and result styles.
• Injected the stylesheet into server-rendered pages via src/pages/site/layout.ts so dynamic tool pages inherit the new look.
• Added stylesheet link to localized homepages (public/_pages/*/index.html) and to the logs viewer (dev-logs/viewer.html).
• Updated several tool pages to use unified classes: input-lg for inputs, btn btn-primary for primary actions, card for main containers, and result for result blocks. Specific pages adjusted: markdown-to-html, website-headers, marginal revenue, BMI, square-feet.
• Simplified and removed some duplicated inline styles in favor of the global stylesheet while keeping a few page-specific helpers where useful.

• Edited: src/pages/howToCalculateBmiPage.ts
• Edited: src/pages/squareFeetPage.ts

Additional fix (2026-01-15 16:10):

• Observed build error: "Unexpected '.'" from src/pages/howToCalculateBmiPage.ts due to a broken template string where CSS was accidentally placed outside the template.
• Fix applied: merged the stray CSS back into the extraHeadHtml template string and cleaned duplicated rules.
• Edited: src/pages/howToCalculateBmiPage.ts

Notes:

• To preview locally, run the project's dev server (e.g. npm run dev or wrangler dev) and open an index or a tool page in the browser.
• I can continue refining tool card grid layout or update additional pages on request.
• After this fix, you can run npm run build or wrangler dev to verify the site builds cleanly.
