The 'cern_overwrite' theme now includes example customisations

The 'cern_overwrite' theme helps developers to make small changes to the way that the 'cern' theme looks and behaves. To date, if you wanted to use it you'd have to learn about the Drupal theme layer and be fairly proficient at CSS. We just reworked the theme to give a few examples out of the box that will hopefully inspire and guide developers. One of the most common theming questions we received in person, for instance, is 'How do I put a background image in the header?' - so we went ahead and put a background image in the header.

Here's what it looks like now:

Questions in the theming forum, please!

Syntax highlighter for CKEditor

Dear CERN Drupal users,

We would like to announce the availability of a new module on the infrastructure to allow syntax highlight of computer code in your content.

The module is managed centrally in the infrastructure, so you don't need to install anything locally to your site.

The configuration and usage of the module is documented here:

If you have any question, request or feedback about the module please use the Entice forum.

Best regards,

Eduardo for Drupal Admins


New backup and restore service for site administrators

Dear CERN Drupal users,


We would like to announce the availability of the new backup and restore service provided by the Drupal infrastructure.

This service allows to you create your own snapshots and recover your site from previous states if needed.

More information about the service can be found in the service's page itself :

Also please find presentations related with this service in the last entice meetings:

'cern' theme updates and color module

On Monday 8 July the Drupal admins are due to deploy changes to the 'cern' theme that I demonstrated during the last Entice meeting. One of the main features that users of mobile devices coming to Drupal sites using the 'cern' theme is a change in the main navigation function, which will look like this:

Following the theme update, site managers will need to save the appearance settings for their sites in order for color module to properly register changes. Failure to do so will result in a transparent nav bar like this:

Instructions for site managers

  1. Go to /admin/appearance/settings/cern
  2. Save the settings
  3. Clear the cache - admin/config/development/performance
  4. That's it

The mobile nav bar will take the same colour as the tab background.

I have issues with my site since the theme update, what can I do?

Please get in touch with me to discuss any issues. At worst I can help you to roll back to an older version of the theme with a local copy.

Toolbar update: site search removed

Following feedback from developers trying to implement the CERN toolbar we have made a number of changes which you will see being deployed soon. The primary impact for Drupal website owners at CERN is that the 'search this site' form will be removed from the toolbar. If you use this feature on your site you will need to implement the search form in another region. We are working on updating the 'cern' theme to improve the way the search form is displayed in the 'header' and 'sidebar' regions.

The changes are expected to be deployed around the second week of March.

CERN Search index tools - initial public release available

Dear CERN Drupal users,

We would like to announce immediate availability of 'CERN Search index tools' module for all Drupal hosted sites.

This module allows to index Drupal content in CERN Search service ( in a structured way and together with already available 'CERN Search' module completes the integration of CERN Search service as backend technology for the Drupal infrastructure hosted sites.

In order to use the module, go to your site administration -> modules menu, enable 'CERN Search index tools' , then visit module help page for detailed description.

Restructured 'cern' theme to go live on infrastructure

Following my last message about the 'cern' theme being available for testing I have asked the Drupal admins to push the rebuilt 'cern' theme to the Drupal infrastructure. This is currently scheduled to be done sometime on the week of 16 July.

Does this affect me?

If you are a site manager for a Drupal site that looks like this one below, then yes. Please read on.

The new theme comes with a number of bug fixes and updates. Notably:

  • IE7 is better behaved. The old 'staircase' effect of the main navigation is fixed, for instance.
  • Variations have gone, color module is in. Select link, text, background and navigation colours to make your site sing - notice, for instance how the Entice site uses a signature orange colour.
  • cern_base DNA. The new 'cern' theme has the same design base as the new CERN website theme, so you'll inherit a richer typography base and grids. It will feel more CERNy when the new core website is live.

What should I do?

If your site uses the current 'cern' theme then please be prepared to check it over once the theme has been upgraded. No action should be necessary on your part, but Silvia and I will be on standby to help you if you experience any unforeseen issues. The main difference you will notice is the altered typography, as seen on the Entice website now.

If you don't want your site to use the new theme, you can add a copy of the current theme locally to your site. Please drop me a note if you wish to do this and I'll talk you through it.

Not already using the 'cern' theme?

If you are using the 'cern_default' theme (our first Drupal 7 theme - the one with lots of whitespace) then you might think about upgrading now. The 'cern' theme has better support for a variety of devices and is actively maintained so that bugs will be worked on.

Entice site now using development version of restructured 'cern' theme

During the last Entice meeting I spoke a little about how we have been working to rebuild the 'cern' theme so that all the themes we are developing - including the new CERN core website - can share the same design DNA. I just switched the Entice site to this new architecture.

If you spot any bugs please report them here:

If you would like to try the theme on your own site before it goes live in the centrally-managed themes, please refer here:
