Using a custom theme for list icons

Using a custom theme for list icons

I used the theme roller to create a simple colour change of the arrow icons for a list (and hopefully also the plus minus symbols on a collapsible list) but can't seem to get the change to kick in.

My css sheets currently look like this with my colour change one being called ' custom_list_arrows.min.css'

  2. <link rel="stylesheet" type="text/css" href="mobile.css" />
  3. <link rel="stylesheet" href="themes/custom_list_arrows.min.css" />
  4. <link rel="stylesheet" href="http://code.jquery.com/mobile/1.3.1/jquery.mobile-1.3.1.min.css" />
    5.  
I have uploaded the new css file and referenced it as above but still the icons remain the default grey. any idea what I may be doing wrong?
