Rosa Lite is an elegant theme for restaurants and cafes.
The free version allows you to create a simple landing page, publish a beautifully designed food menu and run a blog.
To add a Parallax hero header on the homepage, you need to set the featured image for this page. Featured images on other pages work the same way — they become the background images for the hero header of a specific page.
Full features of the theme are revealed after installing all the plugins recommended by the theme from the section Appearance -> Install Plugins.
After that, you can choose the color scheme, for example, dark, pastel or light, use additional page settings, in particular, enable transparency for the navigation menu.
To create blocks on the homepage, the custom heading and columns shortcodes are used. A special shortcode is also used for the restaurant menu. You can access to shortcodes in the visual editor after installing the PixCodes plugin.
