Joomla! World Conference 2026

Since 2008, I am creating websites with Joomla. In 2014 I started volunteering in the Joomla community and I am now active in various teams (Maintainers, Accessibility, Events). I like to write articles for the Joomla Magazine and other blogs. Since 2019, I have been (co-)organising the JoomlaDay Germany / D-A-CH.

Show it, hide it: control your Joomla modules

If you follow my writings, you probably know that I try to use as few extensions as possible. Not because I don’t like extensions, but because I like to keep the websites I create as easy to maintain as possible. There are many cases where extensions absolutely make sense: events calendars, big image galleries, file downloads, etc. In other cases I’m sure I can handle the request with Joomla core and some overrides, because Joomla is a very powerful system.

The hidden power of Joomla’s Articles - Categories Module (and how to use it)

The hidden power of Joomla's Articles: the Categories Module

What if you could have different colors and other styling for each category? With the Articles - Categories Module, you can - and all it takes is a few small tweaks. Joomla offers many modules, but some powerful ones go unnoticed. The Articles - Categories Module is one of them, and with a few small code and CSS tweaks, it can do far more than expected.

CSS Shorts: Logical Properties

CSS logical properties

When we're busy with deadlines and to-do lists, it can be difficult to keep up with new technologies. CSS has evolved dramatically in recent years, and it's not always easy to keep up with the latest developments.

In this article (perhaps it will become a series), I want to focus on a change that makes code easier and more flexible to write, especially for multilingual websites.

Joomla Milestones: 2005-2025

Joomla Milestones 2005 - 2025

Twenty years of development, twenty years of commitment, twenty years of working together: if we'd ask every Joomler to create a timeline of what they consider the highlights and milestones of Joomla's first two decades, no two timelines would be the same. Nevertheless we wanted to give it a try. If you think anything is missing, please use the comments section to tell us what it is and why it should be there! And we'd really love it if you share your personal Joomla highlights as well, you can also do that in the comments. But first, have a look at our impressive timeline!
