How to Create Content placeholder using Html, Css, Js

By Piyush Gupta
Create Content placeholder

Creating a content placeholder using HTML, CSS, and JavaScript involves creating a skeleton screen that mimics the structure of the actual content to provide a visual cue to users while the real content is loading. This technique enhances the user experience by reducing the perceived loading time. Below is a simple example to get you started.

HTML (index.html)

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <link rel="stylesheet" href="style.css" />
    <title>Content Placeholder</title>
  </head>
  <body>
    <div class="card">
      <div class="card-header animated-bg" id="header">&nbsp;</div>

      <div class="card-content">
        <h3 class="card-title animated-bg animated-bg-text" id="title">
          &nbsp;
        </h3>
        <p class="card-excerpt" id="excerpt">
          &nbsp;
          <span class="animated-bg animated-bg-text">&nbsp;</span>
          <span class="animated-bg animated-bg-text">&nbsp;</span>
          <span class="animated-bg animated-bg-text">&nbsp;</span>
        </p>
        <div class="author">
          <div class="profile-img animated-bg" id="profile_img">&nbsp;</div>
          <div class="author-info">
            <strong class="animated-bg animated-bg-text" id="name"
              >&nbsp;</strong
            >
            <small class="animated-bg animated-bg-text" id="date">&nbsp;</small>
          </div>
        </div>
      </div>
    </div>

    <script src="script.js"></script>
  </body>
</html>

 

CSS (styles.css)

@import url('https://fonts.googleapis.com/css2?family=Roboto:wght@400;700&display=swap');

* {
  box-sizing: border-box;
}

body {
  background-color: #ecf0f1;
  font-family: 'Roboto', sans-serif;
  display: flex;
  align-items: center;
  justify-content: center;
  height: 100vh;
  overflow: hidden;
  margin: 0;
}

img {
  max-width: 100%;
}

.card {
  box-shadow: 0 2px 10px rgba(0, 0, 0, 0.2);
  border-radius: 10px;
  overflow: hidden;
  width: 350px;
}

.card-header {
  height: 200px;
}

.card-header img {
  object-fit: cover;
  height: 100%;
  width: 100%;
}

.card-content {
  background-color: #fff;
  padding: 30px;
}

.card-title {
  height: 20px;
  margin: 0;
}

.card-excerpt {
  color: #777;
  margin: 10px 0 20px;
}

.author {
  display: flex;
}

.profile-img {
  border-radius: 50%;
  overflow: hidden;
  height: 40px;
  width: 40px;
}

.author-info {
  display: flex;
  flex-direction: column;
  justify-content: space-around;
  margin-left: 10px;
  width: 100px;
}

.author-info small {
  color: #aaa;
  margin-top: 5px;
}

.animated-bg {
  background-image: linear-gradient(
    to right,
    #f6f7f8 0%,
    #edeef1 10%,
    #f6f7f8 20%,
    #f6f7f8 100%
  );
  background-size: 200% 100%;
  animation: bgPos 1s linear infinite;
}

.animated-bg-text {
  border-radius: 50px;
  display: inline-block;
  margin: 0;
  height: 10px;
  width: 100%;
}

@keyframes bgPos {
  0% {
    background-position: 50% 0;
  }

  100% {
    background-position: -150% 0;
  }
}

JavaScript (scripts.js)

const header = document.getElementById('header')
const title = document.getElementById('title')
const excerpt = document.getElementById('excerpt')
const profile_img = document.getElementById('profile_img')
const name = document.getElementById('name')
const date = document.getElementById('date')

const animated_bgs = document.querySelectorAll('.animated-bg')
const animated_bg_texts = document.querySelectorAll('.animated-bg-text')

setTimeout(getData, 2500)

function getData() {
  header.innerHTML =
    '<img src="https://images.unsplash.com/photo-1496181133206-80ce9b88a853?ixlib=rb-1.2.1&ixid=eyJhcHBfaWQiOjEyMDd9&auto=format&fit=crop&w=2102&q=80" alt="" />'
  title.innerHTML = 'Lorem ipsum dolor sit amet'
  excerpt.innerHTML =
    'Lorem ipsum dolor sit amet consectetur adipisicing elit. Dolore perferendis'
  profile_img.innerHTML =
    '<img src="https://randomuser.me/api/portraits/men/45.jpg" alt="" />'
  name.innerHTML = 'John Doe'
  date.innerHTML = 'Oct 08, 2020'

  animated_bgs.forEach((bg) => bg.classList.remove('animated-bg'))
  animated_bg_texts.forEach((bg) => bg.classList.remove('animated-bg-text'))
}

 

Explanation

  1. HTML:
    • The index.html file contains a placeholder structure and a container for the actual content. The placeholder is displayed initially while the content is loading.
  2. CSS:
    • The styles.css file styles the placeholder elements with a pulsing animation to simulate a loading effect. The .content class is initially hidden and is shown when the actual content is loaded.
  3. JavaScript:
    • The scripts.js file simulates the loading of content using a setTimeout. After 3 seconds, the placeholder is hidden, and the actual content is displayed.

Setup

  1. Create three files: index.html, styles.css, and scripts.js.
  2. Copy the respective code into these files.
  3. Open index.html in your browser to see the content placeholder in action.

Feel free to customize the placeholder design and the actual content structure to suit your needs. This example provides a basic foundation that can be extended for more complex use cases.
