White Spektrum is a responsive theme for ClassicPress that looks great on smartphones, tablets, and everything in between. It pairs a large custom header with left and right sidebar layouts and a mobile menu placed where it’s easiest to reach.

White Spektrum is a parent theme. What this means is that to customize it, you should be creating a child theme. All you need to know is that it is a solid, flexible starting point for any blog.

Features

White Spektrum is built on the rock-solid Backdrop Framework, so it provides a great starting point with many useful features.

  • A large custom header image, with your own header text color.
  • A left or right sidebar layout for your whole site.
  • A menu button at the bottom left on phones, right where your thumb is.
  • Choose medium or large featured images for your posts.
  • Primary and Social menus, and two widget areas: Primary for posts and Secondary for pages.
  • Show a random "powered by" credit in the footer, or write your own.
  • A settings page to choose a custom 404 page and turn off emoji scripts and embeds.
  • Threaded comments, and translation ready.

For step-by-step guides, read the White Spektrum documentation.

Child themes

Since White Spektrum is a parent theme, you'll want to create a child theme if you plan on making any customizations. Don't know how to make a child theme? It's relatively simple. Just follow the below steps.

  • Create a theme folder in your /wp-content/themes directory called white-spektrum-child.
  • Then, create a style.css file within your theme folder.
  • At the top of your style.css file, add the below information.
/**
 * Theme Name: White Spektrum Child
 * Theme URI: https://link-to-your-site.com
 * Description: Describe what your theme should be like.
 * Version: 0.1
 * Author: Your Name
 * Author URI: https://link-to-your-site.com
 * Tags: Add, Whatever, Tags, You, Want
 * Text Domain: white-spektrum-child
 * Template: white-spektrum
 */

Template must match the parent theme’s folder name, white-spektrum. From this point, you simply need to start adding your own styles. The White Spektrum parent theme styles will automatically be loaded for you.
