Why?

I confess that i've been hiding under a stone for quite some time when it comes to contemporary HTML stuff, for most of the things i'm doing on the presentation level even good old HTML 1.0 would be sufficient if it weren't for the occasinal tabular data ...

So while i know CSS in theory i've never really looked into the black magic of doing CSS layouts and stuff ... until now ...

What i'm up to right now was to produce a small series of step by step examples on how to use OpenLayers to present customized OpenStreetMap based maps, and for that i wanted to have a simple layout like this:

... oh why do java binaries (java, javac, jar ...) use long command line options starting with a single dash instead of going with the "one dash for one letter options, two dashes for long option names" convention?

I'll probably never learn to type things like java -version instead of java --version right away ...
