Hey everyone,
One of the best ways I’ve found to practice front-end development is by working on small but practical projects. A calculator app is a perfect example — it might look simple, but it teaches you a lot about structuring code, handling user inputs, and designing an interface that people actually enjoy using.
When I built my first calculator project, I focused on three main areas:
- HTML for structuring the display screen and number/operator buttons.
- CSS for styling the layout, button sizes, and making it responsive.
- JavaScript for the actual logic: addition, subtraction, multiplication, division, and handling edge cases like decimals or clearing values.
What surprised me was how much user experience matters, even for something as basic as a calculator. A clean layout, properly spaced buttons, and clear feedback when clicking operations all make the tool feel much smoother to use.
While searching for inspiration, I came across some useful online tools, such as Alicia Calculator Online. It’s a great example of how simple math functions can be presented in a user-friendly way. The interface is clear, and it also includes extra learning features, such as step-by-step breakdowns, which I think are really useful for students.
If you’re starting with web development, I’d recommend trying to code your own version of a calculator. It’s small enough to be manageable, but flexible enough to experiment with new ideas like animations, themes (dark mode), or even advanced functions.
Has anyone else here tried building a calculator app? What challenges did you run into, and how did you solve them? Would love to exchange tips!
