CSS

The style.css file styles the Loan Calculator, making it attractive and easy to use. Below are some key styles:

body {
    background: #4285f4;
    padding: 0;
    margin: 0;
    display: flex;
    height: 100vh;
    flex-direction: column;
    justify-content: center;
    align-items: center;
    font-family: 'Courier New', Courier, monospace;
}

.container {
    background: black;
    color: aliceblue;
    padding: 20px;
    border-radius: 10px;
}

.input {
    width: 100%;
    font-size: 20px;
    height: 30px;
}

.payment {
    font-weight: 600;
    font-size: 20px;
}

.footer {
    color: white;
    margin-top: 120px;
    text-align: center;
}

JavaScript

The script.js file contains the logic for calculating the loan payment and updating the display. Here’s a snippet:

function calculateLoan() {
    let loanAmountValue = document.getElementById("loan-amount").value;
    let interestRateValue = document.getElementById("interest-rate").value;
    let MonthsToPayValue = document.getElementById("months-to-pay").value;

    let interest = (loanAmountValue * (interestRateValue * 0.01)) / MonthsToPayValue;
    let monthlyPayment = (loanAmountValue / MonthsToPayValue + interest).toFixed(2);

    document.getElementById("payment").innerHTML = `Monthly Payment: ${monthlyPayment}`;
}
