Appearance
Custom Post Types
The theme registers three custom post types:
- Portfolio Item
arts_portfolio_itemwith the/portfolio/slug. - Service
arts_servicewith the/services/slug. - Album
arts_albumwith the/albums/slug.
The slugs are used in permalinks URLs, making them more user- and SEO-friendly. For example, https://mywebsite.com/portfolio/my-item.
Changing CPT Slugs
If you'd like to change the default slugs listed above, set up this handy free plugin Simple Post Type Permalinks, which extends the default Settings -> Permalinks panel.

/works/%postname%Removing CPT Base
It's also possible to completely remove a slug's base in permalinks. So https://example.com/portfolio/sunrise-in-desert/ will become https://example.com/sunrise-in-desert/ in the same URL structure as the default page post type.
Use this plugin for that task: Remove CPT Base.
