A pretty nice card interaction design that expands the info button into a modal-style, full-size info box using jQuery and CSS3 transitions & transforms.

How to use it:

1. Insert an info box into your card.

<div class="card">
  <div class="hint">
    <span class="icon-info"></span>
  </div>
</div>

2. The core CSS for the card & info box.

.card {
  position: relative;
  width: 240px;
  height: 180px;
  border-radius: 12px;
  background: #fff;
  box-shadow: 0 12px 48px -8px rgba(0,0,0,0.1);
}

.card .hint {
  position: absolute;
  top: -12px;
  right: -12px;
  width: 32px;
  height: 32px;
  background: #000;
  border-radius: 16px;
  transition: all 0.2s ease;
}

.card .hint.show {
  width: calc(100% + 24px);
  height: calc(100% + 24px);
}

.card .hint.show .icon-info:before {
  transform: translate(15px, 10px) rotate(-45deg);
}

.card .hint.show .icon-info:after {
  transform: translate(15px, 10px) rotate(45deg);
}

3. The CSS for the info button.

.card .hint .icon-info {
  position: absolute;
  z-index: 1;
  top: 0;
  right: 0;
  display: block;
  width: 32px;
  height: 32px;
  border-radius: 16px;
  cursor: pointer;
  pointer-events: auto;
}

.card .hint .icon-info:before,
.card .hint .icon-info:after {
  content: '';
  position: absolute;
  width: 2px;
  height: 12px;
  background: #fff;
  border-radius: 2px;
  transform-origin: center center;
  transition: all 0.25s ease;
}

.card .hint .icon-info:before {
  transform: translate(15px, 6px) rotate(0) scale(1, 0.2);
}

.card .hint .icon-info:after {
  transform: translate(15px, 12px) rotate(0) scale(1, 0.5);
}

4. Include the necessary jQuery JavaScript library on the page.

<script src="/path/to/jquery.slim.min.js"></script>

5. The jQuery script to toggle the CSS class when the user clicks on the info button.

$('.hint').click(function() {
  $(this).toggleClass("show");
});
