title: Should image size be defined in the img tag height/width attributes or in CSS?
body: <p>Is it better coding practice to define an images size in the <code>img</code> tag's <code>width</code> and <code>height</code> attributes?</p>
  
  <pre><code>&lt;img src="images/academia_vs_business.png" width="740" height="382" alt="" /&gt;
  </code></pre>
  
  <p>Or in the CSS style with width/height?</p>
  
  <pre><code>&lt;img src="images/academia_vs_business.png" style="width:740px; height:382px;" alt="" /&gt;
  </code></pre>
  
  <p>Or both?</p>
  
  <pre><code>&lt;img src="images/academia_vs_business.png" width="740" height="382" style="width:740px; height:382px" alt="" /&gt;
  </code></pre>
