Howdy fantastic blog! Does running a blog such as this take a great deal of work? I have absolutely no knowledge of programming but I was hoping to start my own blog in the near future. Anyways, should you have any ideas or tips for new blog owners please share. I understand this is off topic nevertheless I simply had to ask. Kudos!
Ok- you need some time to understand the basic of blogging.
Having some understanding of CSS, PHP would be helpfull too.
But Workpress ( I’m using 4.1 ) should help you to start quickly.
If you use my menu MISC -> Workpress Details
you can find out my styles.css changes done compared to the original Twenty Twelve Theme
Very helpful
Thank you
