Prevent hover on touch screen devices

There are 2 simple ways to check for touch support with JavaScript:
  1. You can use Modernizr.js library. Latest versions of Modernizr (2.6.2 for sure) automatically checks for touch support and attaches a .no-touch class to HTML tag, if device doesn’t support touch.
  2. If you do not want to use Modernizr, you can add small piece of JavaScript below, which will do exactly the same thing.

//touch events support and if not supported, attach .no-touch class to the HTML tag.

if (!("ontouchstart" in document.documentElement)) {
   document.documentElement.className += " no-touch";
}

Custom OpenCart 2.3.0.2 theme

Make copies… To start with copy the  default  folder found in upload/catalog/view/theme/default to a new folder in the same directory. Name it “ mytheme “. Then copy the  theme_default.php  file in upload/admin/controller/extension/theme and place it in same directory. Name it “ mytheme.php “. + Rename the class to (line 2): ControllerExtensionThemeMyTheme + Replace all “ theme_default ” text to “ mytheme “. Yes there are a lot (197). Copy the  theme_default.tpl  in upload/admin/view/template/extension/theme and place it in the same directory. Name it “ mytheme.tpl “. + Replace all “ theme_default ” text to “ mytheme “. (48) Cop
