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

November 8, 2022

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, this is not easy to achieve with only gradient, but since you are using transparency it can be achieve with two overlays.

Wrap two div inside a container

<div class='container'>
  <div class="repeating-linear" />
  <div class="repeating-linear inverted" />
</div>

and provide them the gradient in the two opposite direction

.container {
  width: 200px;
  height: 50px; 
  border: 1px solid red;
  position: relative;
}
.repeating-linear {
  position: absolute;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  background: repeating-linear-gradient(
    -45deg,
    black 4px,
    transparent,
    transparent 10px
  );
}
  
.repeating-linear.inverted {
  background: repeating-linear-gradient(
    45deg,
    black 4px,
    transparent,
    transparent 10px
  );
}
