CSS Transitions: Hiding Elements Automatically After a Delay
Hiding elements on a webpage after a specific time interval can be achieved through various methods. While jQuery offers a straightforward solution, CSS transitions provide an innovative alternative for achieving the same result.
Approach:
Despite the limitations of CSS transitions in directly animating properties like display, it is possible to simulate element hiding by leveraging animation and manipulating element visibility.
Implementation:
- Create a CSS animation for the desired duration (5 seconds in this case) using @keyframes.
- Within the animation, set the element's height and width to zero to make it disappear.
- Use animation-fill-mode: forwards; to ensure the element remains hidden after the animation ends.
- After the animation delay (5 seconds), toggle visibility:hidden; on the element to completely remove it from view.
Fiddle:
The following fiddle demonstrates the CSS implementation:
html, body {
height:100%;
width:100%;
margin:0;
padding:0;
}
#hideMe {
animation: cssAnimation 0s ease-in 5s forwards;
animation-fill-mode: forwards;
}
@keyframes cssAnimation {
to {
width:0;
height:0;
overflow:hidden;
}
}
<div>
This technique effectively hides elements after the specified time interval, preventing them from occupying any visible space on the page.

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.

CSS: When Does Case Matter (and When Doesn't)?
Jun 19, 2025 am 12:27 AM
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.
