I'm building a new site with Twentytwelve, and I just noticed that most text styling (EXCEPT underlining) is stripped when the site displays on a mobile device. Boldface and italic and so forth are all there when the pages are viewed on a PC, but when you look at them on a mobile they all disappear.
For instance, on http://www.galbraithmt.com/guide/, the words "use on the trail with your smartphone" and "Free Beta" are boldfaced, but they don't show bold on a mobile.
I have tried every conceivable way of coding bold and italic (starting with the bold and italic buttons on the WP post pages), but nothing works.
How can I get bold and italic in Twentytwelve on a mobile device? Really appreciate your help...
