Its not a good practice to add a module related theming details(css/jquery) in a /sites/all/themes/your_theme folder. In Drupal 7 one can use a module's .info file for including module-specific css/javascripts. Example given below:
Filename: ji_indicator.info
name = Range Idicator
description = Indicates range values & out of range values in different color.
core = 7.x
package = "Jagriti Innovations"
stylesheets[all][] = ji_indicator.css
dependencies[] = custom_formatters
