What are the best CSS single-file stylesheets that you can drop into a semantically correct HTML5 document (i.e.: proper usage of markup) and make the page beautiful? Bonus points if it undoes the "fluidity" of the default UA stylesheet, which makes text hard to read.

While helping my lovely wife with a project, I got to step back into CSS effects. Nice little walk-through.

The trick is to fire a debugger; right when you need it
A debugger; statement, when the DevTools are open, kinda freezes the DOM. No more events are fired and script excecution is completely paused.

But... you can still use DevTools!

This is your opportunity to select that otherwise-impossible thing to select and do what you need to do. You can put that debugger; statement right in your code where you need it (remember DevTools has to be open for it to work). Or (Tim Holman taught me the trick) you can trigger it with a setTimeout() right from the console.

Very nice update to the original "Reload CSS" bookmarklet.
