Code Implementation Edit

The basic block is in place, the next step is to add styles to the block. Feel free to style and adjust for your own preference, the main lesson is showing how to create and load external resources. For this example we’re going to load the colorized gilbert font from Type with Pride.

Note: The color may not work with all browsers until they support the proper color font properly, but the font itself still loads and styles. See for browser support and details on color fonts.

Load Font File

Download and extract the font from the Type with Pride site, and copy it in the assets directory of your plugin naming it gilbert-color.otf. To load the font file, we need to add CSS using standard WordPress enqueue, see Including CSS & JavaScript documentation.

In the gutenpride.php file, the enqueue process is already setup from the generated script, so build/index.css and build/style-index.css files are loaded using:

function create_block_gutenpride_block_init() {
    register_block_type( __DIR__ . '/build' );
add_action( 'init', 'create_block_gutenpride_block_init' );

This function checks the build/block.json file for JS and CSS files, and will pass them on to enqueue these files, so they are loaded on the appropriate pages.

The build/index.css is compiled from src/editor.scss and loads only within the editor, and after the style-index.css.
The build/style-index.css is compiled from src/style.scss and loads in both the editor and front-end — published post view.

Add CSS Style for Block

We only need to add the style to build/style-index.css since it will show while editing and viewing the post. Edit the src/style.scss to add the following.

Note: the block classname is prefixed with wp-block. The create-block/gutenpride is converted to the classname .wp-block-create-block-gutenpride.

@font-face {
    font-family: Gilbert;
    src: url( ../assets/gilbert-color.otf );
    font-weight: 700;

.wp-block-create-block-gutenpride {
    font-family: Gilbert, sans-serif;
    font-size: 64px;

After updating, rebuild the block using npm run build then reload the post and refresh the browser. If you are using a browser that supports color fonts (Firefox) then you will see it styled.
