A modern, responsive web-based calculator designed with a focus on user experience and utility. This project goes beyond basic arithmetic by providing a persistent history log and a fluid, tactile interface.
- Real-time History Panel: Keeps track of your previous calculations so you never lose your data.
- Tactile Feedback: Smooth CSS transitions and active scaling effects on every button press.
- Keyboard Support: Use your physical Numpad or number row for lightning-fast calculations.
- Fully Responsive: Designed with a grid layout that works perfectly on both desktop and mobile screens.
- Smart History Interaction: Click any item in the history panel to instantly load that result back into the main display.
The interface uses a specialized "Slate & Azure" color scheme for high readability and reduced eye strain:
- Background:
#0f172a(Deep Slate) - Calculator Body:
#1e293b - Accent (Equals):
#38bdf8(Azure Blue) - Operators:
#f59e0b(Amber)
- HTML5: Semantic structure for accessibility.
