 presentPrompt() {
  let alert = this.alertCtrl.create({
    title: 'Add Your Question',
    inputs: [
      {
        name: 'would',
        placeholder: 'Would You ',
      },
      {
        name: 'rather',
        placeholder: 'Rather'
      }
    ],
    buttons: [
      {
        text: 'Add',
        role: 'add',
        handler: data => {
          this.wouldquestion = data.would;
          this.ratherquestion = data.rather;
          this.afd.list("Questions/").push({
            would:this.wouldquestion,
            rather:this.ratherquestion,

try 
add app.scss
.alertCustomCss {
        color: #e37b26; // text color for basic alerts
        button {
            color: white !important;
            background-color: color($colors, primary, base) !important;
        }
        .alert-message {
            color: #e37b26; // text color for confirm alerts
            // background-color: color($colors, primary, base) !important;
        }
        .alert-sub-title {
          color: #e37b26; // text color for confirm alerts
        //   background-color: color($colors, primary, base) !important;
        }
        .alert-wrapper {
            background-color: color($colors, gray, base);
        }
        .alert-input {
            color: black;
