So What is Actually wrong with Drupal Theming ?

From the frontend perspective ?

sorry devs you can moan later

2 things:

Divitis

Rich Markup (tm)

<div class="foo bar baz whatever">
  <div class="foo bar baz whatever">
    <div class="foo bar baz whatever">

      <h1 class="pane-title">hello im drupal</h1>

      <div class="node node-type node-viewmode-argh">
        always add another div
      </div>

    </div>
  </div>
</div>

css overload

5 classes for each field

    wait im just a piece of data
</div>

Drupals Frontend Problems:

1. the markup

2 .the css

why

Who's to Blame

Its the :

Developers!

No Its the :

Themers!

One markup to rule! em all

Nobody told us what to do!

Pretty please...

TWIG

Anger driven development ;)

Frontend United! Amsterdam march 2012

TWIG

a little bit of french elegance

Lets make a plan

Drop the what if's

but but but but but what if...

Dont Dumb it down

Themers are not that Dumb

the Frontend experience

  • Start from nothing
  • Dont solve all problems
  • Provide tools
  • Visibility
  • consistency
  • dont dumb it down

New awesome [sjeit]

or 666 reasons why Drupal8 is better than Drupal7

HTML 5

Drupal 8 DON'T support

Pretty markup

<div id="bad-practice">...</div>

Drupal CSS

Drupal 7

CSS Stucture

Build on SMACSS & BEM

CSS architecture (1887918) 
    .notification {
        /* general styles for all notifications */
      }
      .notification--info {
        /* blue color adjustments */
      }

css filenames

Approved

B.A.T. Namescheme

CSS file organization (nid: 1887922)

D8 File Structure

Drupal 8 core

/themes

provide visibility

themes now lives in "/themes"

or "sites/ *** /themes"

D8 File structure modules

modulename/templates/*.html.twig

DEBUG!

where's that template ?

DEBUG!

      $settings['twig_debug'] = TRUE;
settings.php

$settings['twig_debug'] = TRUE;

Drupal7 Mothership (tm)

Mothership

R I P

Theme functions

Compiled

the twig templates are compiled

.scss -> .css

(not to themers: its the same thingie that the compile thingie do)

SQL in a theme ?

Who does that ?

Bad Developers

Themes are markup & css!

SELECT * FROM users

 
      <article class="foo foo-whateverdrupal">
        <article class="foo foo-inner foo-whateverdrupal">
          ....
        </article>
      </article>

Branding & logo

HARD coded

Branding & logo
