Good day, thank you in advance for the advice.
During struggles in establishing some elements that use standard .css, I noticed that instead of standard "Styles.css" file the commands are pulled from strange location/file: http://magento.myDomain.com/%7B%7BMEDIA_URL%7D%7Dstyles.css (and styles.css file missing)
When I tried to open/edit with the help of firebug (FF), I got the text "There are no rules. You can create a rule." I could place standard .css code what solved my issues on the browser view (and shows that the location would be right).
Never the less, I can't find the file or spot a field in Magento CMS to insert the CSS code.
Any advise wherefrom data is pulled for file "%7B%7BMEDIA_URL%7D%7Dstyles.css" or where the file is placed?
For me, it looks like some Magento CMS generated file.. and I have to clue where the field to edit it is placed.
