I recently noticed the following in Adobe Dreamweaver CS3 on the Mac:
When you have inline CSS in your (X)HTML file, you can select the
<style> tag and Dreamweaver will give you the option
Convert Inline CSS to Rule. Lovely! However if you don’t use that option and try again later, it is disabled. I found no way to enable it, except for restarting Dreamweaver.
I did a quick Google, but was not able to find information about this. Bug? Feature? Dreamweaver newby?
