title: CSS: Table - Row with colspan - change whole row color on hover
body: <p>I hope this is not duplicated. I wish the whole row had color changed on <code>tr[child]:hover</code></p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;!DOCTYPE html&gt;
  &lt;html&gt;
  &lt;head&gt;
   &lt;title&gt;&lt;/title&gt;
   &lt;style type="text/css"&gt;
  
    tr[origin]:hover {
     background-color: grey;
    }
  
    tr[origin]:hover + tr[child]{
     background-color: grey;
    }
  
    tr[child]:hover {
     background-color: grey;
    }
  
   &lt;/style&gt;
  &lt;/head&gt;
  &lt;body&gt;
   &lt;table border="1px"&gt;
  
    &lt;tr origin&gt;
     &lt;td rowspan="2"&gt;1&lt;/td&gt;
     &lt;td colspan="2"&gt;Question&lt;/td&gt;
     &lt;td rowspan="2"&gt;2/3&lt;/td&gt;
     &lt;td rowspan="2"&gt;View answer&lt;/td&gt;
    &lt;/tr&gt;
    &lt;tr child&gt;
     &lt;td&gt;Rasp 1&lt;/td&gt;
     &lt;td&gt;Rasp2&lt;/td&gt;
    &lt;/tr&gt;
  
    &lt;tr origin&gt;
     &lt;td rowspan="2"&gt;1&lt;/td&gt;
     &lt;td colspan="2"&gt;Question&lt;/td&gt;
     &lt;td rowspan="2"&gt;2/3&lt;/td&gt;
     &lt;td rowspan="2"&gt;View answer&lt;/td&gt;
    &lt;/tr&gt;
    &lt;tr child&gt;
     &lt;td&gt;Rasp 1&lt;/td&gt;
     &lt;td&gt;Rasp2&lt;/td&gt;
    &lt;/tr&gt;
   &lt;/table&gt;
