title: HTML / CSS : Fixed Margin & Fluid Width
body: <p>How should I make this with CSS:</p>
  
  <p>I would like to have 2 <code>divs</code> or more and their <code>width</code> should be in <code>percent</code>, but the margin between the divs should be fixed, in this example <code>30px</code>
  <img src="https://i.stack.imgur.com/UaRQK.png" alt="Fluid Divs"></p>
  
  <p>The problem for me is the margin between the two divs because I can put the divs into a bigger div and set left and right padding to 30px and thats ok, but what should I do with the margin between the two divs?</p>
  
  <p>If I try to add for example to the first div <code>margin-right:30px;</code> then the width of the div will be <code>70% + 30px</code> what will be overall greater than 100% and the second div will fall down.</p>
  
  <p>So what is the solution for this?</p>
