I have to preview in the browser...there is no design view.
I think this probably does okay with CSS although I haven't gotten that far yet..just like there is a tab for coding and writing my pages in html mode, there is a tab I can click on for css which has all the codes and everything I think I will need there....haven't gotten to that bridge yet so I don't know for sure.
This was free too, so it is a nice learning tool for the investment

. If I like I can upgrade to the paid version for 19.95....but even though I had a week's demo with the paid version, so far I can't tell what features I am missing with the free version. Of course it very well may be that I just don't know what I don't yet know!!!
Thanks Lisa...I may upgrade or at least check some of the others out down the road...but I guess this will work for me for now.
