Responsive - Testimonial grid section

I added a wrapper around each testimonial like this:

<article class="testimonial">
    <div class="testimonial__wrapper">
        ...Testimonial elements here...
    <div>
</article>

.testimonial__wrapper {
    display: flex;
    flex-direction: column;
    justify-content: space-between;
    gap: 1rem;
}

The justify-content: space-between will help space out the content if the column stretches. The gap replaces margin-top on the inner elements, so you can remove that!
