title: Best practice for a full width image in wordpress
body: <p>I'm trying to make a featured image 100% width, even if its pixel size is not the width of the screen/body: I'm using the 'full' variable when calling the image via get_the_post_thumbnail but I'm not sure what is the best practice to achieve what I want.</p>
  <ul>
  <li>I can use some JavaScript (it works but I don't know if i like it anymore or if it's the right thing to do)</li>
  <li>I can upload very (2000/2500 px)
  large images, letting scrset manage the smaller sizes. But what if somebody is using a very big screen. And what about the size/quality of the image itself (even if i know how to handle image compression).</li>
  <li>I can remove width and height, along with the sizes=(max-width:pixel) image attribute. This way I can add some CSS rule that let me add some 100% width to the image. But i don't now if this is correct.</li>
  </ul>
