title: Using regular expression in css?
body: <p>I have an html page with divs that have <strong>id</strong>(s) of the form <strong>s1</strong>, <strong>s2</strong> and so on. </p>
  
  <pre><code>&lt;div id="sections"&gt;
     &lt;div id="s1"&gt;...&lt;/div&gt;
     &lt;div id="s2"&gt;...&lt;/div&gt;
     ...
  &lt;/div&gt;
  </code></pre>
  
  <p>I want to apply a css property to a subset of these sections/divs (depending upon the id). However, every time I add a <strong>div</strong>, I have to add the css for the section separately like this.</p>
  
  <pre><code>//css
  #s1{
  ...
  }
  </code></pre>
  
  <p>Is there something like regular expressions in css that I can use to apply style to a set of <strong>divs</strong>.</p>
