smooth-scroll.js

function clickHandler(e) {
    e.preventDefault()
    const href = this.getAttribute('href')
    const offsetTop = document.querySelector(href).offsetTop

    scroll({
        top: offsetTop - 90,
        behavior: 'smooth',
    })
}


// Usage (Make sure these are implemented after DOMContentLoaded
  const links = document.querySelectorAll('.nav-link a')
    for (const link of links) {
        link.addEventListener('click', clickHandler)
    }
