Editing existing default blog post template
Hi, I have imported my clients previous site blog posts but I want to bulk-edit the way they look.
Is this possible without going through one-by-one to edit? Is there somewhere to edit the default blog post template?
For example, I want the background to be white on all posts instead of the site background colour. Also, id like to adjust the fonts and potentially add some more widgets or other info.
Lastly, I would like to be able to adjust how wide the column is for these posts.
Thanks for your help!
