Now I have one of those pretty quote decorations in my quotes on this wiki.

1. The decoration is an image.
2. I used mspaint to capture a large quote mark. I used Engravers MT.
3. I then used paint.net to rotate and flip it, crop it, and then make the white background transparent. As advised in the paint.net forums, I used the magic want tool, capture the background and then “cut” it out.  The file needs to be a transparency supporting format for this to work.

   

4. I uploaded the file to my web server.
5. I then used the WordPress CSS editor to add the following code,

.entry blockquote { background: #EEE url("https://davelevy.info/TOKENS/OQuote_GreyTransparent.png") no-repeat; }

As you can see, the background rule takes two arguments, a base colour and the image, the rune required is the no-repeat key word. It also benefits from the definition of some padding rules. In my case,

     padding-left: 16px; padding-top: 16px;

and now onto fixing the code tag.
