Add a Dynamic Tooltip to a div Element
Question:
Consider a div element with a label and an input field:
<div> <label>Name</label> <input type="text"/> </div>
How do you create a tooltip that appears when users hover over the div element, with a subtle fade-in/fade-out effect?
Answer:
For basic tooltips that display a static message, you can utilize the title attribute:
<div title="This is my tooltip">
However, for tooltips with dynamic text and animated fade effects, a more advanced approach is required:
- Create a CSS animation for the tooltip.
- Add a JS event listener to handle the hover events.
- Create a tooltip DOM element and position it relative to the div.
- Add/remove the tooltip by applying the CSS animation when hovering/removing hover.
Here's an example using JavaScript and CSS:
.tooltip {
display: none;
position: absolute;
padding: 10px;
color: white;
border: 1px solid black;
opacity: 0;
transition: all 0.2s;
}
.tooltip.show {
display: block;
opacity: 1;
}
// Create a tooltip element
const tooltip = document.createElement('span');
tooltip.classList.add('tooltip');
// Add the event listener to the div
const div = document.querySelector('div');
div.addEventListener('mouseover', (e) => {
// Set the tooltip text
tooltip.textContent = 'This is my tooltip';
// Position the tooltip
tooltip.style.left = e.x + 'px';
tooltip.style.top = e.y + 'px';
// Add the tooltip to the body
document.body.appendChild(tooltip);
// Add the show class to the tooltip
tooltip.classList.add('show');
});
div.addEventListener('mouseout', () => {
// Remove the tooltip from the body
document.body.removeChild(tooltip);
});The above is the detailed content of How to Create a Dynamic Tooltip with Fade-in/Fade-out Effects for a Div Element?. For more information, please follow other related articles on the PHP Chinese website!

How can I include CSS only on some pages?
Jun 11, 2025 am 12:01 AM
There are three ways to selectively include CSS on a specific page: 1. Inline CSS, suitable for pages that are not frequently accessed or require unique styles; 2. Load external CSS files using JavaScript conditions, suitable for situations where flexibility is required; 3. Containment on the server side, suitable for scenarios using server-side languages. This approach can optimize website performance and maintainability, but requires balance of modularity and performance.

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.
