My blogging tool is Windows Live Writer and I use the "Insert From Visual Studio" plug-in to get pretty looking code into my postings.  The generated code uses the <pre> tag for formatting the elements. 

Unfortunately my blog provider doesn't always render this properly and will clip text that is too long.  Ideally I would like to either

  1. Wrap code that overflows the page
  2. Put up a localized scroll bar for the code snippet

Luckily the plug-in puts the outer most <pre> tag into it's own CSS class: code.  This makes the problem easy with a CSS override.

pre.code {
  overflow : auto;
