I've been playing with editing CSS on a dummy blog http://localktest.wordpress.com . I'm new to CSS but have read all the CSS-for-dummies posts and reviewed a few tutorials.
Problem: Even when I make simple, one-line changes, for which I know the code is correct, because I lifted it from the answers to previous forum questions, I do not see the correct changes using Preview, even when forcing a refresh. No changes were visible in IE; when I switched to Firefox, I would see the first change, but if I made any subsequent changes, they would not appear.
For info, I'm currently playing with the Bueno theme and attempting simple changes like header font, font size, font color, etc. I have not pasted the entire original code into my CSS box; simply adding changes. Unfortunately, not seeing much, so I do not know if it is browser-related, Bueno-related, or Preview-related.
Also, I do realize that there is not staff support and that (clearly-good-karma-blessed) volunteers stop by to help out. Any advice would be much appreciated.
The blog I need help with is localktest.wordpress.com.
