I need to change my old and basic blog theme with a responsive and professional one, and I was very impressed by your themes Simpleton, DotMag, Top, Simple, Spike and Wildfire and I’m going to get one of them. But I wonder how they’d look like with my content. On the homepage of my blog www.ideawebitalia.it all my posts have a main image, a title, the author attribution, a link to the original article and the first one or two paragraphs. Do you think I can just change theme from the administration panel, to get the content shown right? Or do I have to change and adapt the content, to the new templates? Does it involve changing the database tables (alter or create tables)? Can I just get back to my original theme with a click?
