This example demonstrates a concise animation technique using FSCSS. Let's compare standard CSS animation with the FSCSS approach.
Standard CSS Animation:
The HTML is simple:
<h1></h1> <div></div>
The CSS uses @keyframes to define the animation:
h1, div {
animation: change 3s linear infinite;
}
@keyframes change {
0% {
background: red;
width: 0;
height: 0;
}
100% {
background: #00f;
width: 150px;
height: 150px;
}
}
This creates an animation where both the <h1> and <div> elements transition from a red, zero-sized square to a blue, 150px square.
FSCSS Animation:
FSCSS offers a more compact syntax. Here's the FSCSS equivalent:
$(@keyframes h1, div &[3s linear infinite]) {
0% {
background: red;
%2(width, height[: 0;])
}
100% {
background: #00f;
%2(width, height[: 150px;])
}
}
The $(...) syntax encapsulates the @keyframes declaration, applying it to both <h1> and <div>. The %2(width, height[: ...]) is a shorthand for setting both width and height properties simultaneously.
CodePen Example:
The provided CodePen link (http://www.miracleart.cn/link/dd32c0fc8172acd5312c1089a5aa4d33) visually demonstrates the animation's effect. This allows you to see the animation in action and compare the brevity of the FSCSS code. The animation shows a smooth transition between the red and blue squares.

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.

What is Autoprefixer and how does it work?

Autoprefixer is a tool that automatically adds vendor prefixes to CSS attributes based on the target browser scope. 1. It solves the problem of manually maintaining prefixes with errors; 2. Work through the PostCSS plug-in form, parse CSS, analyze attributes that need to be prefixed, and generate code according to configuration; 3. The usage steps include installing plug-ins, setting browserslist, and enabling them in the build process; 4. Notes include not manually adding prefixes, keeping configuration updates, prefixes not all attributes, and it is recommended to use them with the preprocessor.

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.
