I've noticed that with the Opera browser, some HTML block doesn't render as expected. It is the case of all <pre>, <note>, <impo>, <warn> in the docs for example. The opera default style for this kind of HTML code is to add a margin between the top border of the block and the text. There is a little precision to add to the style file (/css/main.css) to correct this bug: PRE, P { margin-top: 0; }
Created attachment 21185 [details] opera-style.png The current rendering of <pre> and <note> blocks with opera.
Another adjustement would be to remove the font-size from the code class (rendering by firebird for <c> in <note> is unreadable otherwise).
Okay, change committed.
