Meta Box Color Picker to CSS Custom Property Workflow in Bricks

This Pro tutorial provides the steps to declare a custom property (CSS variable) whose value is equal to the post-specific color set via a custom field created using Meta Box in Bricks builder 1.5 Beta and above.

We shall

  • create a field group for page post type i.e., static Pages having a page_color Color Picker type of field
  • write code that checks if the current page being viewed is a static Page and that Meta Box is active and
    • store the value of page_color field in a variable
    • set it to a default/fallback color if the field is empty
    • build CSS having a --page-color custom property with the value of the page_color variable
    • add the above CSS to one of the enqueued stylesheets

With this in place, we can simply specify the color value as var(--page-color) in Bricks editor and the Page-specific color or a fallback color will be used depending on whether the field is populated or not.

    hi, this looks interesting, however, can we have some case studies for use cases please.

      Hi Ash. Here are a couple of use cases:

      1) Pages can have their own unique color schemes. For example, button backgrounds/borders, link colors for Contact page can be blue while they are all purple for About page.

      2) Sitewide Primary color, Secondary color, Background color etc. can be changed by the client in a Settings page and these can be set to be used inside by you in the Bricks builder. For this use case, the code needs a little tweaking.
