CSS for an "index card" effect:

<div class="card-title">
      Milkshake
    </div>
  <div class="card">
    
    <span class="card-text">

        <li>1/8c cream</li>
        <li>1c ice cream</li>
      </ul>
      <p>Blend well, top with whipped cream or crushed candy, and serve cold.</p>
    </span>
  </div>

/* Styling specific to an index card */
.card {
  background-color: white;
  background: repeating-linear-gradient(rgb(240,250,250), rgb(240,250,250) 25px, #9198e5 26px, #9198e5 27px);
  height: 300px;
  width: 500px;
  padding: 0;
}
.card-title {
  background-image: linear-gradient(rgb(240,250,250), rgb(240,250,250) 42px, pink 43px, pink 44px, rgb(240,250,250) 46px);
  height: 46px;
  width: 500px;
  padding-left: 25px;
  padding-top: 3px;
  color: black;
  line-height: 46px;

CSS Tips:

Typing Effect:
HTML:

<div class="wrapper">
  <div class="typing-demo">
    This is a typing demo.
  </div>
</div>

CSS:

.wrapper {
  height: 100vh;
  /*This part is important for centering*/
  display: grid;
  place-items: center;
}

.typing-demo {
  width: 22ch;
  animation: typing 2s steps(22), blink .5s step-end infinite alternate;
  white-space: nowrap;
  overflow: hidden;
  border-right: 3px solid;
  font-family: monospace;
  font-size: 2em;
}

@keyframes typing {
  from {
    width: 0
  }
}

@keyframes blink {
  50% {
    border-color: transparent
  }
}

Drop shadow: When you work with transparent images you can use drop-shadow() filter function to create a shadow on the image’s content, instead of box-shadow property which creates a rectangular shadow behind an element’s entire box: filter: drop-shadow(2px 4px 8px #585858)
HTML

<div class="wrapper">
  <div class="mr-2">
    <div class="mb-1 text-center">
      box-shadow
    </div>

    <img class="box-shadow" src="https://markodenic.com/man_working.png" alt="Image with box-shadow">
  </div>

  <div>
    <div class="mb-1 text-center">
      drop-shadow
    </div>

    <img class="drop-shadow" src="https://markodenic.com/man_working.png" alt="Image with drop-shadow">
  </div>
</div>

CSS:

.wrapper {
  height: 100vh;
  display: flex;
  align-items: center;
  justify-content: center;
}

.mr-2 {
  margin-right: 2em;
}

.mb-1 {
  margin-bottom: 1em;
}

.text-center {
  text-align: center;
}

.box-shadow {
  box-shadow: 2px 4px 8px #585858;
}

.drop-shadow {
  filter: drop-shadow(2px 4px 8px #585858);
}
