Question

Steps to create a div with a z-index of 1 that fills the entire height:

Looking at the image, I have a sidebar that opens over other elements (blue color) using z-index = 1. When the sidebar is open, I want to hide all other elements except for the sidebar. However, towards the end of the sidebar, I can still see other elements from the page such as Sheets A and Sheets B.

I have tried setting different values like 100vh, 500vh, 100%, auto but none seem to work. Is there a way to make the element with Z-index = 1 occupy the entire vertical screen?

.navigationbar--open .navigationbar__body {
    max-height: auto;
    opacity: 1;
}

<div className="navigationbar--open">
    <div className="navigationbar__heading">

        <div className="foldersection">
            <img src={image} className="navbar__icon" />

        </div>
        <FaSortDown />
    </div>
    <div className="navigationbar__body">

          <li>Folder A</li>
          <li>Folder B</li>
          <li>Folder C</li>

Answer №1

To achieve the desired outcome, CSS properties such as overflow, display, height, and width can be utilized effectively. In this demonstration, I ensure that the navbar element spans the entire screen by setting its height to 100vh (representing 100% of the vertical viewport) and preventing vertical scrolling or display of other elements with the overflow-y property set to hidden. Toggling the button element triggers a change in the display property to flex for the nav element. See the example below.

$('.btn').click(function() {
    $('nav').toggleClass('open');
});

nav {
    height: 100vh;
    width: 100vw;
    background: pink;
    overflow-y: hidden;
    position: fixed;
    top: 0;
    left: 0;
    display: none;
    flex-direction: column;
}

nav.open {
    display: flex;
}

.btn {
    position: absolute;
    top: 25px;right: 25px;
    z-index: 2;
}
