Implementing File Explorer Effect Using HTML/CSS

This example creates a simple file explorer layout using Button in CSS. You can expand on this by adding hover effects, click events, and more sophisticated styling as per your requirements.

HTML

<button class="button">
  <div class="container">
    <div class="folder folder_one"></div>
    <div class="folder folder_two"></div>
    <div class="folder folder_three"></div>
    <div class="folder folder_four"></div>
  </div>
  <div class="active_line"></div>
  <span class="text">File Explorer</span>
</button>

HTML & CSS

To create a basic file explorer effect using HTML/CSS, you can build a simple structure with some styling to represent files and folders.

<!DOCTYPE html>
<html lang='en'>

<head>
  <meta charset='UTF-8'>
  <meta name='viewport' content='width=device-width, initial-scale=1.0'>
  <title>File Explorer</title>

  <style>
    .button {
      position: relative;
      display: flex;
      align-items: center;
      justify-content: center;
      width: 5.3em;
      height: 5.3em;
      border: none;
      border-radius: .4em;
      background: rgba(235, 252, 254, 0.8);
    }

    .container {
      position: relative;
      width: 3.5em;
      height: 3.1em;

      overflow: hidden;
    }

    .folder {
