Achieving Glass Effect in CSS Overlays: Resolving Blur Issues
Problem: Applying a blur effect on an overlay div proves challenging, leaving the contents behind the overlay unblurred. Seeking a simple and cross-browser solution.
Solution:
The example provided in the jsfiddle exhibits the common issue with blur effects in CSS overlays: they blur the overlay itself instead of its backdrop. To rectify this, consider leveraging the backdrop-filter property.
Updated CSS:
#overlay {
... (previous CSS) ...
backdrop-filter: blur(6px);
}
Advantages:
- More precise: Blurs the backdrop instead of the overlay, achieving the desired effect.
- Cross-browser compatibility: Supported in major browsers, including Chrome, Firefox, and Edge.
- Simplified code: Removes the need for multiple filter properties, providing a cleaner and more maintainable solution.
Note:
Browser support for backdrop-filter may not be perfect, particularly in older versions. However, it offers a significant improvement over the previously implemented CSS filters and is generally sufficient for most use cases where blur effects are non-essential.

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.
