Here’s an example of a simple currency converter that uses JavaScript, HTML, and CSS, and also utilizes a free API to get the exchange rates:

JAVASCRIPT
<script type="litespeed/javascript">function convertCurrency(){const amount=document.getElementById('amount').value;const from=document.getElementById('from').value;const to=document.getElementById('to').value;fetch(`https://api.exchangerate-api.com/v4/latest/${from}`).then(response=>response.json()).then(data=>{const rate=data.rates[to];const convertedAmount=rate*amount;document.getElementById('result').innerText=convertedAmount})}</script>
This code will create a simple form with two currency dropdowns and a button to initiate the conversion. When the button is clicked, the convertCurrency function is called, which makes a request to the Exchange Rate API to get the exchange rate for the selected currencies. The function then calculates the converted amount and updates the result element on the page with the result.
You can customize this code by adding more currencies to the dropdown lists, or by using a different API to get the exchange rates.

To use this CSS, you can add it to your HTML file inside a <style> element, or you can include it in a separate file and link to it in your HTML using a <link> element.
This CSS styles the body text, the heading, and the form elements to make them look more visually appealing. It also adds some hover effects to the button. You can customize the styles further to match your desired design.
