 * I’ve always updated without issue but the last update created some problems. 
   It seems recent wp updates favor and support the twenty series, so I’m thinking
   of changing to twenty twelve but have questions like … 1) do I have to know css?
   2) what is width? body and sidebar? 3) what’s largest photo size body can hold?
   And, can I work on building (adding header, etc.) before going live.
 * This is my 5 year old blog. Does it look like an easy transition. [http://foodalogue.com](http://foodalogue.com)

 * Not really – WordPress works fine with many, many themes, but if yours is outdated
   or has code that’s not up to WP standards, yes, there can be problems.
 * You don’t have to know CSS, but if you want to do any customizations, it helps
   a lot. In your case, you would likely need to do that to make your existing site
   work right in a new theme. But CSS isn’t that hard to learn — this is a good 
   place to start: [http://www.w3schools.com/css/](http://www.w3schools.com/css/)
 * Basic HTML knowledge will be helpful too:

 * Width is how wide the site or elements in the site are. Body is an HTML tag —
   basically it contains everything that is displayed on the page. The largest photo
   size depends entirely on your theme.
 * Yes, you could create a separate development site to work on before going live
   with a new theme — see this:

 * So far as “easy transition,” it’s really impossible to know, but in general, 
   if your theme is 5 years old, it may take some work to make it work in a new,
   current theme. You can easily just try out some themes and see what happens.

 * Thank you for informative response. I will check links and see if there’s some
   clarity.
