title: HTML/CSS:CamelCase vs Underscores
body: <p>I have read lots of articles about advantages and disadvantages of camelCase and Underscore naming conventions. I've always prefered camelCase mainly because it saves bytes.</p>
  
  <p>But learning about BEM, I've been really confused. BEM naming is more readable but '_','__' and long names add file size. Also I couldn't found any js plugins with it. So which one is better for qualified webpage?</p>
  
  <p>P.S. sorry for bad English. Any opinion is appreciated</p>
