Eksell is a free portfolio WordPress theme with deep block editor support and lots of features.
Block Editor Support
Eksell is built to make it fun and easy to create advanced layouts in the block editor. The block editor is styled to match the front-end of your site, and the theme includes plenty of block patterns.
All colors in Eksell can be changed in the Customizer, and your changes are reflected in the block editor preview. You can also set a separate dark mode color scheme for devices that support it.
The home page has a content filter that allows your visitors to filter your posts by category. The filter updates the post grid without a hard reload, and supports the Jetpack Portfolio content type as well.
Blank Canvas Page Template
Eksell includes a Blank Canvas page template, which hides all elements except the blocks you add to the page in the block editor. That means that you can create completely custom layouts.
Eksell makes extensive use of CSS variables and includes plenty of actions and filters, which makes it easy to modify and extend it with child themes and custom CSS code.
Eksell also features infinite scroll on archive pages, a search overlay, a sticky header, a social menu with icons, custom logo support, and a lightweight construction to ensure short load times.
