Answer 1

Use two gradients:

div {
  height: 300px;
  background: #fff;
  border: 3px solid #000;
  background: 
    repeating-linear-gradient(#0000 0 10px,#fff 0 20px),
    linear-gradient(to right, orange, lightblue, orange);
}

<div>
</div>

Answer 2

You can use a tool like this to create your own gradient: https://cssgradient.io/

Instead of using multiple span tags you probably want to use multiple background rules, combined with child selectors, something in this direction:

div{
  width:100%;
  height:300px;
  background:#fff;
  border: 3px solid #000;
  display:flex;
  justify-content:center;
  align-items:center;
  flex-direction:column;
}

div.card{
  width:100%;
  height: 300px;
  background: linear-gradient(-45deg, rgba(159,175,192,1) 0%, rgba(199,208,208,1) 33%, rgba(155,174,190,1) 67%, rgba(199,208,208,1) 100%);
  display:flex;
  justify-content:center;
  align-items:flex-start;
}

span {
  width: 50%;
  height: 10px;
  background: black;
}

span:nth-child(2n) {
  background: linear-gradient(45deg, rgba(159,175,192,1) 0%, rgba(199,208,208,1) 50%, rgba(159,175,192,1) 100%);
}

span:nth-child(2n - 1) {
  background: #dbe4eb;
}

<div>
  <div class="card">
    <span></span>
    <span></span>
    <span></span>
    <span></span>
    <span></span>
    <span></span>
    <span></span>
    <span></span>
    <span></span>
  </div>
</div>
