I know there is this post on changing the placeholder text. I've tried implementing in on my textarea tags
textarea::-webkit-input-placeholder {
color: #fff;
}
textarea:-moz-placeholder { /* Firefox 18- */
color: #fff;  
}
textarea::-moz-placeholder {  /* Firefox 19+ */
color: #fff;  
}
textarea:-ms-input-placeholder {
color: #fff;  
}
but it's not doing anything. What am I missing?
This is what one of my textarea's looks like
<textarea
  onChange={(e) => this.props.handleUpdateQuestion(e, firstQuestion.Id)}
  placeholder="Overall Satisfaction Question"
  name="SEO__Question__c"
  type="text"
  className="slds-input"
  value={firstQuestion.SEO__Question__c ? firstQuestion.SEO__Question__c : ''}
  style={inputStyle}
  autoFocus
/>
