title: How can I change a calc value to a fixed value?
body: <p>Suppose, I have applied in my stylesheet many times a calc() css like this:</p>
  
  <pre><code>div{width: calc(100% - 200px);}
  div.test{height: calc(100% - 300px);}
  </code></pre>
  
  <p>but I want these width and height a fixed width like this </p>
  
  <pre><code>div{width: 100200px;}
  div.test{height: 100300px;}
  </code></pre>
  
  <p>I need to change this with jQuery for some tricky method. But this should be changed which width is applied <code>calc(100% - 200px);</code> such as using filter function.</p>
