Splash Screen in Web App using JS and HTML Issue

Time：01-19

I am making a website, and though that adding to it a splash screen would be nice and make the website much fancier. I made the code for it, but the issue, the text appears OK, but the text doesn't disappear after the set time which is 1 second it doesn't disappear, I mostly rechecked and didn't spot an error and when I run it, it works and no errors are given.

const splash = document.querySelector('.splash');

document.addEventListener('DOMContentLoaded', (e)=>{
    setTimeout(()=>{
        splash.classList.add('display-none');

    }, 2000);
})
body {
    padding: 0;
    margin: 0;
    background: black;
  }
  .navbar {
    overflow: hidden;
    padding: 5px;
    margin: 0;
    top: 0;
    position: sticky;
    background: black;
    color: white;
    opacity: 85%;
  }
  .navbar-item {
    display: inline-block;
    padding: 5px;
  }
  .left {
    float: left;
    font-weight: bold;
    font-size: xx-large;
  }
  .right {
    float: right;
    font-size: x-large;
  }
  .no-style-link {
    text-decoration: none;
    color: inherit;
  }
  .main-content {
    padding: 10px;
    text-align: center;
  }
  .ytvidcollection {
    padding: 10px;
    background: #6969f8;
  }
  .ytvid {
    padding: 5px;
    background: red;
  }
  .ytvid:hover {
    -ms-transform: scale(1.1);
    transform: scale(1.1);
  }
  .copyright {
    background: #333030;
    color: white;
    text-align: center;
    bottom: 0;
    font-size: x-large;
    padding: 10px;
  }
  #Jothin-kumar {
    font-size: xx-large;
    text-decoration: none;
    color: red;
  }
  #Jothin-kumar:hover {
    text-decoration: underline;

CodePudding user response：

using jquery,

document.addEventListener('DOMContentLoaded', (e)=>{
    setTimeout(()=>{
      $(".splash").css("display", "none");
    }, 2000);
})

CodePudding user response：

You're adding a 'display-none' class but this isn't included anywhere in your CSS.

Just adding this to your CSS should fix it:

.display-none {
  display: none;
}


const splash = document.querySelector('.splash');

document.addEventListener('DOMContentLoaded', (e)=>{
    setTimeout(()=>{
        splash.classList.add('display-none');

    }, 2000);
})
body {
    padding: 0;
    margin: 0;
    background: black;

.splash {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
