Build fast, accessible, and SEO-friendly websites with modern best practices.
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.
Images are the #1 cause of slow sites โ use WebP/AVIF, lazy-load below-the-fold, and set explicit width/height to prevent layout shift Render-blocking CSS delays first paint โ inline critical CSS in <head>, defer the rest Third-party scripts (analytics, chat widgets) often add 500ms+ โ load them with async or defer, audit regularly Fonts cause invisible text flash (FOIT) โ use font-display: swap and preload critical fonts Measure with Lighthouse in incognito mode โ extensions skew results
Start CSS with mobile styles, add complexity with min-width media queries โ easier to scale up than strip down Touch targets need 44x44px minimum โ fingers are imprecise, small buttons frustrate users Test on real devices, not just browser DevTools โ throttling simulation misses real-world jank Horizontal scroll is a critical bug โ test every page at 320px width minimum viewport meta tag is required: <meta name="viewport" content="width=device-width, initial-scale=1">
Every <img> needs alt text โ empty alt="" for decorative images, descriptive text for meaningful ones Color contrast ratio 4.5:1 minimum for body text โ use WebAIM contrast checker Form inputs must have associated <label> elements โ placeholders alone are not accessible Keyboard navigation must work โ test every interactive element with Tab key Screen readers announce heading hierarchy โ use H1-H6 in logical order, never skip levels
One <h1> per page only โ it's the page title, not a styling tool Use semantic elements: <nav>, <main>, <article>, <aside>, <footer> โ they communicate structure to browsers and assistive tech <button> for actions, <a> for navigation โ don't use divs with click handlers External links should have rel="noopener" โ prevents security vulnerability with target="_blank" Validate HTML โ broken markup causes unpredictable rendering across browsers
Avoid !important โ it breaks cascade and makes debugging painful. Fix specificity instead Use relative units (rem, em, %) over fixed px for text โ respects user font size preferences CSS custom properties (variables) reduce repetition โ define colors and spacing once, use everywhere Flexbox for 1D layouts, Grid for 2D โ don't force one to do the other's job Test without CSS loading โ content should still be readable in plain HTML
Missing favicon causes 404 spam in server logs โ always include one, even a simple PNG Not setting <html lang="en"> breaks screen reader pronunciation Hardcoded http:// links break on HTTPS sites โ use protocol-relative // or always https:// Assuming JavaScript is available โ core content should work without JS (progressive enhancement) Forgetting print styles โ add @media print for pages users might print (receipts, articles)
Test all forms actually submit โ broken contact forms lose leads silently Check 404 page exists and is helpful โ default server 404 looks unprofessional Verify social sharing previews with Open Graph tags โ test in Facebook/Twitter debuggers Submit sitemap to Google Search Console โ speeds up indexing Set up uptime monitoring โ know when your site goes down before users tell you
