// so I have an image inside <Layout> with margin-top: -255px;, which is sitting under nav bar. when I set style of  Layout.Header as rgba(255,255,255,0.9) it's not set transparent. it seems there is a white layer underneath or sth. sorry if I'm wrong. I am a beginner. 

      <Layout.Header className="header">
      </Layout.Header>
      
// css file
.header {
  background: rgba(255,255,255,0.9);
  height: 57px;
}
