title: how to use CSS to hide a header contains specific text
body: <p>I want to hide a header text from the website.</p>
  
  <p>because the same element "h2" has been used in more than one page, i can't apply a "display:none" to it. </p>
  
  <p>I have tried it. The result is that it will remove other page's header too. </p>
  
  <p>is there a way to apply CSS so that it only hides when the header text contains specific words?</p>
  
  <p>i will be appreciate for any help i may get here</p>
