I would like to make small css changes such as h1 and various font, background colors and divs etc. I am using Newsflash theme on Drupal 7 and I have searched and searched my folders thus: sites> all> themes> newsflash> css> local.css
I can probably override things here but I would prefer to go to the source stylesheet if it exists. Does it exist? If not, is local.css the right place to write my changes?
