**NOTE This session is moved to Sunday 10am!**

Drupal 8 has many new exciting features, but none are as radical or as needed as the changes made to the theme system*!

For 10 years Drupal's front end was design and built by developers that tried their very best to figure out what the front end needed; the lack of dedicated front-enders in core; resulted in front end architecture that was "less than ideal" for the challenges that the front end has faced for the last 5 years.

Drupal 8 and twig changed it all!

A complete overhaul of the theme system started 3 years ago - PHPtemplate is now out the door, the twig template system is implemented, and most importantly, the core idea of how the front end is build has done a 180° from how Drupal 7 handled theming.

This means:

No more divitis!
No more Class soup
No more of Drupal's standard markup and classes
No more yelling at the markup and not knowing where stuff came from
No more using regex for modify a CSS class!
Such a dramatic change would normally cause panic is a time for celebration.

The session will give you a solid understanding of the key concepts of Drupal 8 theming, as a themer, as well as giving insight to why the drupal8 theming is changed so radical.

The session will cover:

• "Best practice" of Drupal8 theming.
• The structure of a Drupal 8 theme's
• Classy and Stable, what happend with basethemes
• How {{ twig }} works from a CSS/HTML coders perspective (how to build a theme)
• A detailed look into fields, loops & how to completely control the markup

* Yes I know that a lot of “big things came into d8” that weren't front end related ;)
** This is the "next version" of the session I gave at DrupalCon Los Angeles & Barcelona, it builds on feedback from attendees & the changes that have happend since beta to RC1 to 8.0
