Expand card js

The javascript will be used for adding a click event listener on the image. This project is responsive from small to large devices. The first image is active and the other needs to be clicked. When clicked the image will float from left to right or right to left. Check the js code below.

script.js

const panels = document.querySelectorAll('.panel')

panels.forEach(panel => {
    panel.addEventListener('click', () => {
        removeActiveClasses()
        panel.classList.add('active')
    })
})

function removeActiveClasses() {
    panels.forEach(panel => {
        panel.classList.remove('active')
    })
}
