Purity III has its own style for both 404 and Offline pages. They are customized from default Joomla 404 and Offline pages.

404 page

Offline page

If you want to customize the 2 pages, follow the instructions below.

Step 1: Define which CSS file to be loaded

Open files error.php and offline.php in templates/purity_iii/.

error.php file - 404 page

<link rel="stylesheet" href="/<?php echo $this->baseurl; ?>/templates/purity_iii/css/error.css" type="text/css" />

The 404 page loads error.css file in templates/purity_iii/css/.

offline.php file - Offline page

<link rel="stylesheet" href="/<?php echo $this->baseurl ?>/templates/purity_iii/css/offline.css" type="text/css" />
  <link rel="stylesheet" href="/<?php echo $this->baseurl ?>/templates/purity_iii/css/general.css" type="text/css" />

The Offline page loads offline.css and general.css files in templates/purity_iii/css/.

Open the 2 css files to customize style of 404 and Offline pages.

#frame {
  background: #fcfcfc;
  border: 1px solid #ddd;
  margin: 100px auto 0;
  width: 600px;
}

/* Logo */
#frame h1 {
  background: #07b;
  color: #fff;
  margin: 0;
  padding: 15px 0;
  text-align: center;
}

Note:

The offline.css and error.css files are not overridden when you compile LESS to CSS so you can customize style of the 2 pages directly in the 2 .css files.

In demo site, Purity III does not have "Back to top" button, but you can add the button to your site. For this guide, please reference to T3 documentation, it's the same for all templates developed with T3 framework.
