What is the best way to ensure that the background color in CSS fills the entire browser window?

Question

Is there a way to expand the background color to fill the entire browser window?

.top{
    background-color:green;
    color: white;
    height:1000px;
    display: flex;
    flex-direction: column;
}

<div className = "top">
    <Header/>
    <Body />   
</div>

I attempted setting the height to 100%, but it did not work as expected. How can this be resolved?

.top {
  background-color: green;
  color: white;
  display: flex;
  flex-direction: column;
  width: 100vw;
  height: 100vh;
}

<div class="top">
  <Header/>
  <Body/>
</div>
