The theme by itself is useful, but you may have an easier time getting up and running by installing a skeleton. The Klb4 theme can be found in both the Website which are self-contained repositories for a complete sites which include: sample content, configuration, theme, and plugins.

You should now have all the theme files under


Default Options

Klb4 comes with a few default options that can be set site-wide. These options are:

enabled: true                   # Enable the theme
production-mode: true           # In production mode, only minified CSS is used. When disabled, nested CSS with sourcemaps are enabled
grid-size: grid-lg              # The max-width of the theme, options include: `grid-xl`, `grid-lg`, and `grid-md`
header-fixed: true              # Cause the header to be fixed at the top of the browser
header-animated: true           # Allows the fixed header to resize to a smaller header when scrolled
header-dark: false              # Inverts the text/logo to work better on dark backgrounds
header-transparent: false       # Allows the fixed header to be transparent over the page
header-showexternallinks: true  # Allows an outher menu type in header
header-externallinks:           # A array list of links for menu
sticky-footer: true             # Causes the footer to be sticky at the bottom of the page
blog-page: '/blog'              # The route to the blog listing page, useful for a blog style layout with sidebar
custom_logo:                    # A custom logo rather than the default (see below)  
custom_logo_mobile:             # A custom logo to use for mobile navigation

To make modifications, you can copy the user/themes/klb4/klb4.yaml file to user/config/themes/ folder and modify, or you can use the admin plugin.

NOTE: Do not modify the user/themes/klb4/klb4.yaml file directly or your changes will be lost with any updates

Custom Logos

To add a custom logo, you should put the log into the user/themes/klb4/images/logo folder. Standard image formats are support (.png,.jpg, .gif, .svg, etc.). Then reference the logo via the YAML like so:

    - name: 'my-logo.png'
    - name: 'my-mobile-logo.png'    

Alternatively, you can you use the drag-n-drop "Custom Logo" field in the Klb4 theme options.

Page Overrides

Klb4 has the ability to allow pages to override some of the default options by letting the user set body_classes for any page. The theme will merge the combination of the defaults with any body_classes set. For example:

body_classes: "header-dark header-transparent"

On a particular page will ensure that page has those options enabled (assuming they are false by default).

Hero Options

The hero template allows some options to be set in the page frontmatter. This is used by the modular hero as well as the blog and item templates to provide a more dynamic header.

hero_classes: text-light title-h1h2 parallax overlay-dark-gradient hero-large
hero_overlay: true # Enable overlay effect
hero_search: true # Enable plugin simplesearch on hero page
hero_image: road.jpg
hero_align: center

The hero_classes option allows a variety of hero classes to be set dynamically these include:

  • text-light | text-dark - Controls if the text should be light or dark depending on the content
  • title-h1h2 - Enforced a close matched h1/h2 title pairing
  • parallax - Enables a CSS-powered parallax effect
  • overlay-dark-gradient - Displays a transparent gradient which further darkens the underlying image
  • overlay-light-gradient - Displays a transparent gradient which further lightens the underlying image
  • overlay-dark - Displays a solid transparent overlay which further darkens the underlying image
  • overlay-light - Displays a solid transparent overlay which further darkens the underlying image
  • hero-fullscreen | hero-large | hero-medium | hero-small | hero-tiny - Size of the hero block

The hero_image should point to an image file in the current page folder.

Features Modular Options

The features modular template provides the ability to set a class on the features, as well as an array of feature items. For example:

class: standard
        icon: 'fa fa-desktop'
        header: Systems
