title: How to style ion-alert header in ionic
body: <p>I created an alert controller and am trying to style the <code>header</code> of the alert. I have checked out the docs but i couldn't find any solution.</p>
  <pre><code>  async showAlert(header, subHeader, message) {
      const alert = await this.alertCtl.create({
        cssClass: &quot;my-custom-class&quot;,
        header,
        subHeader,
        message,
        buttons: [&quot;Ok&quot;],
      });
      alert.present();
    }
  </code></pre>
  <p>How do i style the <strong>header</strong> of the alert ?.</p>
  <p><strong>Edit:</strong>
  This is the global.scss file</p>
  <pre><code>.my-custom-class {
    .alert-wrapper {
      .alert-head {
        color: green;
      }
    }
  }
  
  </code></pre>
  <p>Have tried this as suggested by @Vijay Kumawat but it still the same.</p>
