Your „own“ content management

Content Management is a special form of Web-Development. It enables customers/users to edit the content of an internet appearance – to change or to extend the structure of a page. 


Despite there being a great number of CMS systems we prefer to use our own: depage::cms. 


depage::cms was originally developed for Hesse design, but now a good many websites have it. We first developed it because we were not happy with the user interface of the existing CMS systems. 

depage::cms is based on PHP, MySQL and a Flash based interface. 


For more information about depage::cms there are links to Source-Repository, short documentations etc. on the depage::cms-website

depage-forms: validation of html5 forms (Part II)

article by Frank Hellenkamp

Validation of HTML form data

Thanks to the new HTML Standard and the WHATWG Group it is easier than before to have Browsers show standard errors when a user does not provide valid data inside an input element. Unfortunately this only works in newer Browsers, and not in older ones (e.g. Internet Explorer 8). 


To make it easier for developers, depage-forms provides an way easy way to add validation to forms that works in all three different places at the same time: 

  • on the server

  • in the browser, based on the new html standard

  • in the browser, based on javascript

Getting things done without getting the word out

article by Frank Hellenkamp


It has been a very long time since I managed to publish an article here. And it's not because there wouldn't be anything to talk about. But we are working a lot, so there is no time left to show and tell. Why? Well, because there is always a next project waiting to be finished.  


And I am sure, we are not the only ones having this problem: A lot of freelance designers and small agencies I know don't have the time or resources, to publish what they are doing regulary. Some people just shout on Twitter or on Facebook instead, but I have to admit: I like not to brag. But I think that some of the things we do are worth seeing nontheless. 


I already wanted to write about this... more than year ago. 

But this has to change – Starting right now! 

So, what were we working on?

So first, there is Screen-Pitch: 

Screen-Pitch is an online platform which enables screen-writers to present their film ideas to producers in the form of video pitches. Originally founded by Linus Foerster, Ben and I implemented based on depage-cms.

depage-forms: html5 forms made easy (Part I)

article by Frank Hellenkamp / Sebastian Reinhold

HTML forms: Easy and difficult at the same time

HTML-Forms are simple to write – but to do it in a good way and to make them comfortable to use is not an easy task. 

There are a few things you will have to do again and again: 

  • Write the HTML for the form itself

  • Style the form in the right way

  • Validate the data in the browser (optional)

  • Validate the data on the server (never optional - don't forget!)

  • Additionally make sure the user don't have to fight with the browser e.g. strange messages about "resending" data on reloading the page and using back- and forward-buttons.

lot's of free space for text

article by Frank Hellenkamp

Because text needs love: is online! 


textfreiraum is a editorial agency, that takes the liberty to write articles, features and commentary independently as possible. We were invited to design their new internet appearance. Because textfreiraum lives and breathes through text, we had to find a layout that leaves a lot of space for the various texts. 

The content: Essays about Design

Textually textfreiraum consists of three basic topics: 

depage::cms goes opensource

article by Frank Hellenkamp

This year the official decision has finally been made: We will publish the coming depage::cms version under an opensource license, thereby making it available to a wider base of users and developers. 


Because this process will take some time (documentation, source code management on the basis of git, etc.) we must ask you to bear with us. If you are interested and would like to be informed about new developments, you can register for our newsletter and we will keep you up to date.
