Sasson is a powerful base theme intended for advanced drupal theming, aiming at bringing the fun back to theming.
it is a collection of many open source goodies combined together.

What it does ?

  • It includes Sass & Compass framework (via a modified PHamlP) - no extra requirements, simply enable and start writing sass/scss.
  • It's mobile friendly - with responsive, content-first layout, out of the box. optional mobile-first responsive layout, media queries break-points are configurable.
  • It converts the core template files to HTML5 markup -
    for nodes,
    for blocks, for sidebars, for menus etc.(thanks Boron)
  • It includes a perfectly semantic grid system - no more non-semantic grid classes (based on 960gs via Compass).
  • It includes an HTML5-friendly CSS Reset (normalize), cross-browser styling compatibility improvements and other tweaks & best practices from HTML5Boilerplate v2.0
  • It *doesn't* give you a pile of CSS rules you will have to override.



  • Adaptive grid - on your theme settings you may choose width, # of columns, gutter width, we (well, SASS) do the math.
  • Ready made sub-theme. just copy, rename, and start theming
  • FireSASS support
  • HTML5 support in oldIEs (IE 6-8) via HTML5shiv
  • HTML5 doctype and meta content-type
  • Search form uses the new input type="search" attribute
  • WAI-ARIA accessibility roles added to primary elements
  • Many extra body and node classes for easy theming
  • Responsive menus (thanks to jqueryMobileDropdown)
  • Optional blueprint grid system integration, no more vendor prefixes, simple IE fixes, and many more - all thanks to compass
  • Google web-fonts support, right from your theme settings.
  • Draggable overlay image you can lay over your HTML for easy visual comparison with your design.
  • Grid background "image", for easy element aligning, made with CSS3 and SASS to fit every grid you can imagine.
  • oh, and RTL support, of course.



  • Bad way - Extract the theme in your sites/all/themes/ directory, enable it and start hacking
  • Good way -
    1. Extract the theme in your sites/all/themes/ directory
    2. Copy SUBTHEME into its own folder in your themes directory
    3. Rename at least your folder and .info file
    4. Enable your sub-theme and start hacking
  • Even better - you can use drush to create your sub-theme(s) -



- html.ie9 #selector { ... } /* IE9 only rules */
- htm.lte-ie8 #selector { ... } /* IE8 and below rules */

  • Out of the box Sasson will give you a 960 pixel grid system, you may change grid properties in your theme settings.
  • Sasson gives you a responsive layout - that means your site adapts itself to the browser it is displayed on. you may set the layout breakpoints or disable this behaviour via theme settings.
  • The default responsive layout takes a desktop-first approach, you can go mobile-first with a click in your theme settings.
  • While you develop, you should keep the development mode turned on (see theme settings page), this will compile your SASS on every page load, and will give you FireSASS support.
  • When not developing, turn development mode off, this will keep your CSS output light as a feather, in fact, the output of our semantic version of 960gs is much slimmer then the original css grid system.
  • Sasson allows you to write CSS3 properties (like 'border-radius', 'box-shadow' etc.) in the standard form, vendor specific prefixes will be added for you. see hook_prefixes_alter() if you want to add more.
  • Sasson passes variables from the theme settings form and into the sass compiler, you can do this in your sub-theme as well, see hook_sasson_alter().
  • Sasson will force latest IE rendering engine (even in intranet) & Chrome Frame, you may disable that via theme settings.
  • Sasson will set mobile viewport initial scale to 100%. with a responsive layout, this will give your mobile users the best experience, no need to zoom on every page load, you may disable that via theme settings.
  • sass/scss files are compiled to css files with the same name, when manually creating multiple sub-themes, you should avoid having two sass/scss files with the same name as they will override each other, if using drush snsto create sub-theme we take care of that for you.
  • When loading style-sheets in your .info file Sasson allows you to specify settings like media queries, browsers, weight and any option available to drupal_add_css(), this example will load sasson.scss with an extra weight for screen only (not print) on browsers wider then 400px and on IE7 or older only :
    styles[styles/sasson.scss][options][weight] = 1
    styles[styles/sasson.scss][options][media] = screen and (max-width:400px)
    styles[styles/sasson.scss][options][browsers][IE] = lte IE 7
    styles[styles/sasson.scss][options][browsers][!IE] = FALSE
  • Sasson applies classes to the tag to enable easier styling for Internet Exporer



Sasson was started as 965 but have since evolved into new areas.
most of the ideas here came from many super talented developers, credits is left where credit is due.
Thanks perelman nir for the name and raz konforti for making it work so amazingly good.
The bugs are mine.
