What I learned

In this challenge, I was able to implement my basic JavaScript knowledge, like accessing a DOM element and creating an interaction. I also applied an if conditional to change the image icon on the right side of the question. Overall, it was really cool.

const faqs = document.querySelectorAll('.faq-item');

faqs.forEach(faq => {
    faq.addEventListener('click', () => {
        const img = faq.querySelector('.faq-question img');
        img.style.opacity = '0';
        setTimeout(() => {
            if (faq.classList.contains('active')) {
                img.src = './assets/images/icon-minus.svg';
            } else {
                img.src = './assets/images/icon-plus.svg';
            }
            img.style.opacity = '1';
        }, 60);
        faq.classList.toggle('active');
    })
})

Continued development

Now that I have finished this challenge, I want to continue working on basic projects until I have enough confidence to tackle more advanced ones. I am reinforcing my knowledge with JavaScript, so soon I will venture into doing the best challenges.

Useful resources

• Google Fonts - This helped me to use external fonts instead of local ones, so that everyone can identify the type of font I used for this challenge.
• nekpCalc - I used this page to support me with relative measurements like rem. I used it as a reference to use the rem measurement in my project and improve the challenge.
