title: What does "./" (dot slash) refer to in terms of an HTML file path location?
body: <p>I know <code>../</code> means go up a path, but what does <code>./</code> mean exactly?</p>
  
  <p>I was recently going through a tutorial and it seems to be referring to just a file in the same location, so is it necessary at all? Can I just not use it if that's all it's doing?</p>
