Maik Derstappen: Plone 6 Theming with Diazo

How does Plone theming look in classic UI?

• html5 theme plus a mapping configuration
• deploying themes as ZIP-file for shared hosting is possible
• With Diazo you can map any Plone html to a static theme layout.

Separating frontend and backend theme. Don't reinvent the backend views! You could theme the backend, so for content editors and admins, but it looks fine, not needed. You should focus on the frontend layout for visitors. To use the default backend layout you can include backend.xml in your rules, with some conditions.

Diazo is not for everything! If the backend markup differs from what you need, do not try to solve it with Diazo or XSLT. Instead, fix the backend templates directly, most likely with a z3c.jbot override.

You can use theme fragments or browser views to add new templates. The theme fragments can also be used as tiles in Mosaic.

I like using SASS mixins. Say you have a

. Cleaner would be

class="main-wrapper">

. You can do this with mixins with @include in your selector.
