I use custom CSS and HTML that is not featured in the Visual Editor for a few different reasons. For example, I apply CSS to image attributions, blocks of text, and so on. And you know what? I’m just plain lazy. Going into the HTML editor and manually typing in code is just a step too far for me.
So for some time I have been searching for a plugin that will facilitate my laziness. A quicktags plugin that works with the Visual Editor as well as the HTML editor. I finally found one – and it works a treat.
