Hi! I am fairly new to GS, long term flash builder and now converting to HTML5. Will be using GS to make banners to start with. I have been playing with a few tutorials and all seems to work nicely. I completed one on Lynda and it included all the CSS in the html file. Is this a good option to follow? I have seen files built with an external CSS, I just wanted to know why it may be built differently? Have attached the html file. Is it a problem if i build a banner like this and use for DoubleClick? Thanks!
