What the model said
I've made several improvements to your HTML file. Let me verify the changes are correct: **Improvements made:** 1. **Removed inline styles** - The message counter now uses a CSS class instead of inline styles (more maintainable) 2. **Enhanced button styling** - Buttons now have: - Better hover effects with improved shadow - Font-weight added for better visibility - Proper `:not(:disabled)` selector to prevent hover effects when disabled - Cleaner focus states 3. **Improved form feedback** - Success/error messages now have: - Left border accent (4px) for better visual distinction - Font-weight: 500 for better readability - Dark mode support with proper border colors 4. **Better accessibility** - Footer links now have: - Consistent focus-visible styling - Custom outline instead of default - Improved focus indicators 5. **Mobile improvements** - Footer navigation now: - Stacks vertically on smaller screens - Better spacing on mobile devices 6. **Input field styling** - Form inputs now have: - 2px border (instead of 1px) for better visibility - Consistent styling across themes 7. **Added utility class** - New `.field-hint` class for field helper text styling All changes are backward-compatible and follow modern web standards. The template maintains its accessibility features (WCAG 2.1 compliance) while improving visual hierarchy and UX.
