If you have wondered where expandable code examples have gone and what has happened to non-expandable ones, they have not gone anywhere. I am just making some changes to WordPress to make my own updates easier in the future. I have been implementing new plugin for WordPress and because I have no sandbox installation of WordPress to play with I am doing changes in live.
When I started to write my blog I had no means to present code examples in visually appealing way. First I modified WordPress style sheets and added new css class .code to apply into my examples. Soon after I started to add longer examples and noticed that they destroy the readability of the post. So I created expandable code blocks.
Please, bear with me..
