Interoperability? Ha, ha, ha, ha, ha. It's funny -- funny-strange, not funny-ha-ha -- that cyber-catastrophe seems to know the precise time to needle the user for maximum effect. Gonzo programmer that I am, over the weekend I decided that rather than simply add a few menu items in the sidebar to my blog, I should shift the entire site to CSS. No more tables, just blocks of stuff floating here and there. Professional. In one touch, I could recast hundreds of pages in Halloween orange and black if the spirit moved me.
Of course, I tried to do this without manuals. It's like riding a motorcycle without a helmet or swinging from the high trapeze without a net. I fell. The new site looks wildly different in each popular browser. Things look great in Mozilla, iffy in Internet Explorer, and unworkable in Opera. Oh joy.
Looking for navigation and links? Page-down. They're down there somewhere.
