Create Stunning Gradual Div Reveals with JavaScript setTimeout and CSS Transitions

Jan 14, 2025 pm 08:09 PM

This tutorial demonstrates how to gradually reveal webpage elements using JavaScript's setTimeout function and CSS transitions. The effect creates a visually engaging, staggered appearance of divs, each fading in sequentially.

Overview

This example showcases a series of divs, each containing an image and link, that fade in one by one. setTimeout controls the timing, while CSS handles the smooth transition.

HTML Structure

The HTML consists of several divs, each holding an image and a link. This structure is ready to receive the styling and JavaScript functionality. (Note: The provided HTML snippet is incomplete and lacks closing tags. A complete, functional HTML file is required.)

CSS Transitions

The CSS defines the visual transition:

.toggle-div {
  opacity: 0; /* Initially hidden */
  transition: opacity 1s ease; /* 1-second fade-in transition */
  height: 50px; /* Ensure visibility */
  background-color: lightblue; /* For visual clarity */
  margin: 10px 0;
  padding: 12px 80px;
  display: flex;
  align-items: center;
}

.toggle-div img {
  height: 100%;
  margin-right: 8px;
}

.toggle-div a {
  font-size: 20px;
}
  • opacity: 0;: Hides the divs initially.
  • transition: opacity 1s ease;: Specifies a 1-second smooth opacity transition.

JavaScript for Gradual Reveal

The JavaScript code orchestrates the staggered appearance:

// JavaScript to reveal divs
const divs = document.querySelectorAll('.toggle-div');

divs.forEach((div, index) => {
  setTimeout(() => {
    div.style.opacity = 1; // Make div visible
  }, index * 500); // Delay based on index (0.5 seconds per div)
});
  • document.querySelectorAll('.toggle-div'): Selects all elements with the class toggle-div.
  • forEach: Iterates through each div.
  • setTimeout: Sets a timer before setting opacity to 1, causing each div to fade in after a delay. The delay increases by 500 milliseconds (0.5 seconds) for each subsequent div.

Explanation of JavaScript

The JavaScript uses a forEach loop to iterate through the selected divs. setTimeout is crucial; it introduces a delay before setting the opacity to 1, thus creating the staggered reveal effect. The delay is calculated as index * 500, resulting in a 0.5-second delay between each div's appearance.

What is 'render-blocking CSS'? What is 'render-blocking CSS'? Jun 24, 2025 am 12:42 AM

CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.

In CSS, selector and attribute names are case-sensitive, while values, named colors, URLs, and custom attributes are case-sensitive. 1. The selector and attribute names are case-insensitive, such as background-color and background-Color are the same. 2. The hexadecimal color in the value is case-sensitive, but the named color is case-sensitive, such as red and Red is invalid. 3. URLs are case sensitive and may cause file loading problems. 4. Custom properties (variables) are case sensitive, and you need to pay attention to the consistency of case when using them.
