title: Running PostCSS compiled style sheets through purifycss with Gulp
body: <p>I have a task that first runs CSS files through postcss plugins and then through purifycss like this:</p>
  
  <pre><code>.pipe(postcss(processors))
  .pipe(purify(['src/test/html/*.html']))
  .pipe(gulp.dest(PLI.target.test.css));
  </code></pre>
  
  <p>However the CSS is not being purified.  Anyone know why?</p>
  
  <p>The actual task that is running the build can be found here: <a href="https://github.com/superfly-css/superfly-css-task-build" rel="nofollow noreferrer">superfly-css-task-build</a></p>
  
  <p>If you clone this <a href="https://github.com/superfly-css/superfly-css-component-button" rel="nofollow noreferrer">project</a> and run <code>npm i &amp;&amp; npm run test</code> and then look in the <code>target/test/css/index.css</code> all the un used CSS is still contained in the file even though <code>src/test/html/index.html</code> is used as the purifycss filter.</p>
