Most browser-based email clients (Gmail, Yahoo, etc.) strip out the head and body tags from HTML emails. You never really know what's going to be removed, so the safest thing is to inline all of your styles.
These are great, and really simple to use. Already adapted for my latest project!
Also, if you didn't catch it in there: the [premailer][1] library is awesome, and helps make email templates more manageable (use CSS/LESS/SCSS styles like normal, then run your HTML email through premailer before shipping and it'll inline everything for you). I use the Python library with Django to preflight emails before sending. Works like a charm!
> Although in fact the decline of the value of the dollar is relatively predictable because of the Federal Reserve's policy goal of keeping inflation relatively low and the law of large numbers as applied to the generation of the real rate of inflation.
That's a crucial point. If the Fed didn't pledge to keep inflation under control, the dollar wouldn't be such a great store of value or medium of exchange. It's the stability promised by central banks that allow you to "predict the value of a dollar" in the immediate future.
