title: C# ASPX Set h1 background color runtime
body: <p>I want to change the background color of my h1 header line on my webpage at runtime. If we are running in prod/dev I want the background color of the H1 header tag set accordingly. </p>
  
  <p>I currently am setting the background color for h1 as follows:</p>
  
  <pre><code> align="center" style="background-color: #389BD6 "&gt;HEADER 1 LINE
  </code></pre>
  
  <p>But I want to be able to specify the color differently depending on the current environment.</p>
  
  <p>I am assuming it will involve a css, but that is new to me and need some help.</p>
  
  <p>Thanks</p>
