const justFeet = totalFeet.addEventListener('input', (e) => {
    const heightInFeet = e.target.value;
    let displayFeet = document.createElement('h3')
    displayFeet.textContent = heightInFeet * 12
    // totalInches.appendChild(displayFeet)
})

const justInches = inches.addEventListener('input', (e) => {
    const addOnInches = e.target.value;
    let displayInches = document.createElement('h3')
    displayInches.textContent = addOnInches
    // totalInches.appendChild(displayInches)
})
    
function totalHeight (feet, inches) {
    const finalTotal = feet + inches;
    let finalHeight = document.createElement('h3')
    finalHeight.textContent = finalTotal
    totalInches.appendChild(finalHeight)
}

totalHeight(displayFeet, displayInches)
