title: Which are good references for mobile webdev?
body: <p>I would like to get a bit more into mobile webdev and searching for books or screencasts about this topic. Of course I found dozents, but I don't know which to choose. </p>
  
  <p>Does it make sense to read books with a design part in it, although I won't ever make a design, but only implement them?</p>
  
  <p>Any suggestions out there, are there some must have reads?</p>
  
  <p>Thanks for your help!</p>
  
  <p>EDIT: I am mainly searching for books, which cover themes like media-queries and so on. I have to put designs in to web pages and would like to improve my skills by making them mobile friendly.</p>
