Tip Calculator App made with HTML, CSS & JS

Hello! Great job~ 😀

Here are few suggestions:

• Use button or radiobutton elements for the tip selection (Screen reader users won't know it's to be clicked if you use a div.
• Change the RESET text to Reset. Find out more here 😀
• Instead of using innerHTML for the texts, an alternative would be textContent. You can read about their differences here. But for this current use case, both can be used. 😉
• For the tip buttons' event listeners, there seems to be lots of repeated code. In this case, you can use a single function for them all. For example:

for(const tipBtn of tipButtons){
 tipBtn.addEventListener('click', handleTipClick)
}
const handleTipClick = (event) => {
            let tipValue = 1  // Change it to whatever the default tip value is
            const selectedTip = event.target.value
            if(selectedTip === '5%'){
              tipValue = 5
            }
            let totBill = Number(inputBill.value)/100*tipValue
            let totPeople = Number(nrPersone.value)
            totTipOutput.innerHTML =(totBill/totPeople).toFixed(2) + "€"
}

The code above is written with the assumption that radio buttons are used 😉. Also, it might or might not work but, the general idea is there. 😀

Thank you for the suggestion, I was looking for a way to shorten my code 😁 and you give me a great solution! Regarding the RESET comment is also interesting, I learn something absolutely new 🙏
