How can I create a gradient on a rectangular div with repeating lines at a 45 degree angle in opposite directions?

I want to create a gradient with lines moving in both directions, but at a 45 degree angle. with html and css. How can I do the same lines, but in an opposite direction.

This is the code I used below to produce the image above.

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>

<style>
  .repeating-linear {
  background: repeating-linear-gradient(
    -45deg,
    black 4px,
    transparent,
    transparent 10px
  );

}
</style>

</head>
<body>
    <div class="repeating-linear" style="width: 200px;height: 50px; border: 1px solid red;">

    </div>
</body>
</html>

Solution

So you want cross lines, you can stack gradients as proposed below:

<div class='repeating-linear' />

.repeating-linear{
  width: 200px;
  height: 50px; 
  border: 1px solid red;
  background: 
    repeating-linear-gradient(
      -45deg,
      black 4px,
      transparent,
      transparent 10px
    ),
    repeating-linear-gradient(
      45deg,
      black 4px,
      transparent,
      transparent 10px
    );
}
