Auto CSS Extractor Tool

Paste a complete HTML page (Tailwind/Bootstrap/custom). Tool will load it in different viewport widths, extract used CSS rules (including responsive media queries), dedupe, and return an optimized HTML with an inline \\n'; if (optimized.indexOf('') !== -1){ optimized = optimized.replace('', styleTag + ''); } else { optimized = styleTag + optimized; } // Pretty basic cleanup: remove duplicate whitespace optimized = optimized.replace(/\\n{3,}/g, '\\n\\n'); // Output results output.textContent = optimized; log('\\n=== Process Complete ==='); if (warnings.length) { log('\\nWarnings:'); warnings.forEach(w => log(' - ' + w)); } setProgress(1); setStatus('Done'); } // UI bindings startBtn.addEventListener('click', async (e) => { startBtn.disabled = true; await convertCode(); startBtn.disabled = false; }); clearBtn.addEventListener('click', () => { input.value = ''; output.textContent = ''; logEl.textContent = ''; setProgress(0); setStatus('Cleared'); }); copyBtn.addEventListener('click', async () => { try { await navigator.clipboard.writeText(output.textContent || ''); alert('Optimized HTML copied to clipboard'); } catch(e){ alert('Copy failed: ' + e.message); } }); downloadBtn.addEventListener('click', () => { const blob = new Blob([output.textContent || ''], {type:'text/html'}); const url = URL.createObjectURL(blob); const a = document.createElement('a'); a.href = url; a.download = 'optimized.html'; document.body.appendChild(a); a.click(); a.remove(); URL.revokeObjectURL(url); }); copyLogBtn.addEventListener('click', async () => { try { await navigator.clipboard.writeText(logEl.textContent || ''); alert('Log copied to clipboard'); } catch(e){ alert('Copy log failed: ' + e.message); } }); })(); //]]>
