This seems to be a common problem with Twitter - when I post the html code on my webpage, it renders as hyperlink text. I am using a combination of Muse and Dreamweaver.
When I paste the code in Adobe Muse and then view it in Preview (within Muse), it shows the icon, but part of it is cut off and it my Facebook widget disappears. When I go over the Dreamweaver and put the code in, it renders as a hyperlink text. I’ve tested it in Fireworks and Safari and how it is showing up in Dreamweaver is how it is displaying in both of those browsers.
