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:

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_overlay: true # Enable overlay effect
hero_showsearch: true # Enable plugin simplesearch or tntsearch 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
