I have a webpage that I'm trying to design but I'm stuck with persistant whitespace on the right side of the page. I have tried resetting the browser defaults but this has no effect on the page. I have also tried to make sure that the parent elements all have a declared size but this too has had no impact.

Webpage:

html,
body {
  height: 100vh;
  width: 100vw;
  overflow: hidden;
}

.navbar {
  height: 5%;
  background-color: #181818;
}

.siteContainer {
  color: #ffffff;
  width: 100%;
  height: 100%;
  margin: 0;
}

.siteBody {
  height: 100%;
}

.searchArea {
  background-color: #181818;
}

.resultArea {
  background-color: #121212;
}

<div class="container siteContainer">
  <div class="row navbar">
    <div class="col col-2 ">
      Logo
    </div>
    <div class="col col-10 ">
      Navbar
    </div>
  </div>
  <div class="row siteBody">
    <div class="col col-2 searchArea">
      Search and CRUD
    </div>
    <div class="col col-10 resultArea">
      Results
    </div>
  </div>
</div>

CodePudding user response：

Youre using bootstraps container class which has fixed max widths (see https://getbootstrap.com/docs/5.1/layout/containers/).

What you want it container-fluid which fills 100% of the page.
