I want to use divs that resize based on the presence of certain ruby  
variables.

How would I insert my size variable into a div like this

\<% @width = 30 %\>

\<%=  
“\<div id=‘inner\_meal\_pan\_overview’ width=‘100%’  
style=“width:#{@width}em;”\>”  
%\>

---

that’s not absolutely wrong, only those slashes are not necessary  
if you use single parentheses:  
\<%= “

” %\>

Also \<% @width = 30 %\> should really go in the controller action
