How Can I Animate Dashed Borders in CSS3 Without SVG or JavaScript?

Animating Dashed Borders Using CSS3 Animation

Inspired by an article on Tympanus, you aim to incorporate the eye-catching dashed border animation into your WordPress blog posts. However, the challenge lies in replicating this effect without relying on SVG or JavaScript.

To achieve this with CSS alone, you can leverage the power of multiple backgrounds. By combining two linear gradients and adjusting their positions through animation, you can create the illusion of a dashing border. Here's how:

<code class="css">.border {
  height: 100px;
  width: 200px;
  background: linear-gradient(90deg, blue 50%, transparent 50%),
              linear-gradient(90deg, blue 50%, transparent 50%),
              linear-gradient(0deg, blue 50%, transparent 50%),
              linear-gradient(0deg, blue 50%, transparent 50%);
  background-repeat: repeat-x, repeat-x, repeat-y, repeat-y;
  background-size: 16px 4px, 16px 4px, 4px 16px, 4px 16px;
  background-position: 0px 0px, 212px 116px, 0px 116px, 216px 0px;
  padding: 10px;
  transition: background-position 2s;
}

.border:hover {
  background-position: 212px 0px, 0px 116px, 0px 0px, 216px 116px;
}</code>

This code creates four linear gradients, each with a different direction, and then alternates their positions through the background-position property. The transition property ensures a smooth animation effect when the user hovers over the element.

This approach mimics the dashed border animation without the need for SVG or JavaScript, allowing you to add dynamic borders to your WordPress blog posts with ease.
