I tried pasting this code in the J Query for 320x480, .content .entry-content{ font-weight: bold; } But when I check with my phone, not all posts content are bold.
responsive WHAT? jQuery WHAT? What's the CMS? What's the markup? Are you using a HTML/CSS framework or is it custom code? Much less what the **** does jQuery have to do with responsive layout or that resolution; much less why are you targeting by resolution for font-weight, and targeting in pixels for fonts for?!? You really haven't said enough for anyone to help you, and what you have said is ... disturbing.
