Tailwind, Vanilla

Hi UDOH Well done on your challenge. So far so good. Here are a few things that you can look at.

• Consider setting a maximum number of digits that your calculator can take - you can not have a calculator that will take any input as long as you press a key.
• try the following calculation 0.1 + 0.2
• i can enter 9......67.... as input, set conditions that you cannot enter more than one decimal point and the same applies to the operators eg a scenatio like 98+-*
• You did well on the structure of the html , well done

One thing with tailwind is the bloating of your html making it difficult to read your html (just an opinion)

I didn't solve the challenge but from my perspective, refactor the toggle section by storing the color,background, and box-shadow because they're the same. in case you want to change the value of these properties, you have to go through each individual manually. they're not reusable. the second one is the array of buttons, you don't have to set the index explicitly you can use a loop. that's it. I hope this'll help you to refactor your code.
