title: Customising Zurb Foundation 5 Grid, Gutter and Max width
body: <p>I've only been able to find one or two references to the maximum allowed column we can add to a customized version of Foundation5 and these claim the number is 16. However I can find no official documentation of this.</p>
  
  <p>In the Foundation 5 download customizer there are input fields for '# of Columns', 'Gutter (em)', and 'Max-Width (em)'.
  I have tested with a value of up to 24 columns and the CSS output has classes included for up to 24 columns, so I'd assume the 16 column restriction no longer applies (or only applies to older versions of Foundation).</p>
  
  <p>So my questions are:</p>
  
  <ol>
  <li><p>Does anyone know what the max number of columns allowed is / or if others are using a particular number successfully?</p></li>
  <li><p>If I custom download Foundation5 with more columns, how do I know what gutter width and Max-Width values will work out correctly or can I just use anything (the downloader doesn't give any indication of incorrect values or out of range values)?</p></li>
  <li><p>Having a custom download, how would I best manage Foundation updates if I wanted to upgrade the CSS to future newer versions?</p></li>
  </ol>
  
  <p>PS: Im not using SASS or other pre-processor tools.</p>
