How to add custom css file to subtheme of omega kickstart theme? I have created a subtheme of "omega kickstart theme" and I want to add some custom css files to it. I searched and got some solution(which didn't worked for me), the solution is as follows: 


create your custom css file and place it in css folder of your subtheme. 
edit your subtheme.info file(edit under optional css code of info file) as follows: 

css[yourthemename.css][name] = 'Your custom products styles'
css[yourthemename.css][description] = 'This file holds all the product page CSS of your theme.'
css[yourthemename.css][options][weight] = '12'



The other Solutions were as follows:


Specify your custom css path file in info file as 

stylesheets[all][] = mycustomcss.css

Make use of "drupal_add_css" function in template.php as follows

function MYTHEMENAME_preprocess_node(&amp;$variables) {
  if ($variables['view_mode'] == 'full') {
    $path = drupal_get_path('theme', 'MYTHEMENAME');
    drupal_add_css($path . 'MY-THEME-PATH');//PUT UR CSS FILE PATH
  }
}



I tried this function twice with two different paths. First I gave path as '/css/mycustomcss.css' and second time I gave path as '/MYTHEMENAME/css/mycustom.css'.

UNFORTUNATELY NONE of these solutions worked for me. Am I missing something or is it something else?...please help.
I was missing one line in code. here is what you have to do. in your .info file under optional css code write the following code. 

css[yourcustomcss.css][name] = Your custom products styles 
css[yourcustomcss.css][description] = This file holds all the product page CSS of your theme. 
css[yourcustomcss.css][options][weight] = 12 
settings[alpha_css][yourcustomcss.css] = 'yourcustomcss.css' 


Now go and enable your 'yourcustomcss.css' in Appearance/yourthemename/settings/toggle-styles
