How to define a set of CSS class names so Vim knows how to autocomplete -

Broadly speaking, I am very happy the way Vim automatically completes the words for me. Currently, I have an HTML / CML / JavaScript / CSS framework, which styled one style for a defined set of CSS class names. Class names like

  frameworkgauatable frameworkers_groupInput FrameworkPitaptive   
 that will use  
  .framework_Table {}. .FramWork_NumberInput {} .framework_TextOutput {}   
 The question is, how to / where will I tell these class names to auto-complete the VIM?   
 
 
 You can make full use of dictionary-based.  
 
 
 Enter all your identifiers in a file,  / say path / to /project/cssdict.txt .  
 
  framework_tomet frameworkarm_inumber frameworkcast output    
 
 In Vim, : Setlocal dictionary = / path / to / project / cssdict .txt .   
 
 Hit  & lt; C-x & gt; & Lt; C-k & gt;    
 Read : help 'dictionary'  and : help- compl-dictionary >.
