This (in many ways) has been requested quite often.

I'm going to add in a few things to the starterkit(s) to make it a bit easier to get moving quickly with as little (or possibly no) editing of the .info file in the subthemes created from the starterkit.

  • CSS Changes
    • Add a default enabled stylesheet in the starterkits (custom.css)
    • Add browser specific stylesheet(s)
      • IE6 (ie6_custom.css)
      • IE7 (ie7_custom.css)
      • IE8 (ie8_custom.css)
  • JS Changes
    • Add a default javascript include ready for editing (custom.js)

This will be tested and released in the 2.1 version pending

I'm updating this after a tiny bit of investigation.

The IE stylesheets will be included by Omega if they exist using omega_preprocess_html()

  • CSS Changes
    • Add a default enabled stylesheet in the starterkits (custom.css)
    • Add browser specific stylesheet(s)
      • IE6 (ie6.css)
      • IE7 (ie7.css)
      • IE8 (ie8.css)
  • JS Changes
    • Add a default javascript include ready for editing (custom.js)

Also rather than using custom.css, it's going to use subtheme.css as the default name of the enabled stylesheets so it doesn't overwrite the default omega/css/custom.css styles.

Thanks for a really nice theme! While starting to use Drupal7 I am also changing base theme from Zen to Omega.

In Omega 2.1 you add - if I understand it correctly - conditional style sheets via In Zen you should have used the .info file, something like this:

conditional-stylesheets[if IE][all][] = css/ie.css
conditional-stylesheets[if lte IE 6][all][] = css/ie6.css

Is Omegas way better? In, how do I use "if" etc, e.g. "if lte IE 6"? By the way, wouldn't it be good if there is an ie.css in the starter-kit (which should be used by all IE versions)?

With Zen, the code you pasted requires the Conditional Styles module.

There was work to get this into core for D7 (#522006: Conditional Styles in .info files, since drupal_add_css has it), but it was pushed to D8 in this reply by Dries:

So, while drupal_add_css supports the conditional stylesheets, adding them via a .info file currently is not supported.

Take a look at the core bartik and seven themes and how they are adding the stylesheets.

If that issue is updated at some point (and does get into D7 somehow) I will update the code in Omega to reflect those changes, but it seems it's stuck with this solution until then.

It would be possible in the subthemes preprocess_html (or in Omega: preprocess/ to add

drupal_add_css(path_to_theme() . '/css/ie.css', array('group' => CSS_THEME, 'browsers' => array('IE' => 'IE', '!IE' => FALSE), 'preprocess' => FALSE));

And that should give the "all IE browsers" stylesheet you're looking for. IMHO... with the vast differences between IE6 > IE8, I rarely see too many hacks that need to be in every version.. but then again, I just don't do IE hacks... I refuse to support those crappy browsers.. but that's just me ;)

@himerus: Thanks for your answer. I agree with you concerning IE, but not my customers...

A little bit of topic: how can I *programmatically* add conditional js-scripts (it concerns rounded corners) in Omega?

Nevermind, it works, I just had a typo. :(

> What would I add the for a IE 9 specific stylesheet? I added:

This does not work for me at all, could someone please direct me as to what I am doing wrong.
I want to have an IE specific css file that will get loaded when using IE and will override all of the other css stylesheets.

I have copied the above code that #6 himerus mentioned into a new file called '' and placed it within my omega subtheme folder 'preprocess'

drupal_add_css(path_to_theme() . '/css/ie.css', array('group' => CSS_THEME, 'browsers' => array('IE' => 'IE', '!IE' => FALSE), 'preprocess' => FALSE));

I have created an 'ie.css' file which is within my /css in my subtheme.

Any changes I make to this file are not showing in ie.
