CSS3 Spin Animation
In your provided HTML code, you have applied various CSS3 animation properties to a div element. However, the animation does not appear to be functioning despite using the latest stable release of Chrome.
Understanding CSS3 Animation
To use CSS3 Animation effectively, you must adhere to a specific sequence of steps:
- Define Animation Properties: You must define the animation properties for the element, such as animation-name, animation-duration, animation-iteration-count, and animation-timing-function, as you have done in your code.
- Define Animation Keyframes (Missing in Your Code): You need to establish the actual animation keyframes using the @keyframes rule. The keyframes define how the element should appear at specific points during the animation sequence.
- Browser Compatibility: Ensure that the browser you are using supports CSS3 Animation. Most modern browsers, including Chrome, do support this feature.
Solution: Adding Keyframes
In your code, you have defined the animation properties but not the animation keyframes. To resolve this, add the following keyframes rule:
<code class="css">@keyframes spin {
from {
transform: rotate(0deg);
}
to {
transform: rotate(360deg);
}
}</code>
This keyframes rule specifies that the element should rotate from 0 degrees to 360 degrees during the animation.
Demo
With the keyframes rule added, your code should now be as follows:
<code class="html"><div> </div></code>
<code class="css">div {
... (same animation properties as before)
}
@-ms-keyframes spin {
from { -ms-transform: rotate(0deg); }
to { -ms-transform: rotate(360deg); }
}
@-moz-keyframes spin {
from { -moz-transform: rotate(0deg); }
to { -moz-transform: rotate(360deg); }
}
@-webkit-keyframes spin {
from { -webkit-transform: rotate(0deg); }
to { -webkit-transform: rotate(360deg); }
}
@keyframes spin {
from {
transform: rotate(0deg);
}
to {
transform: rotate(360deg);
}
}</code>
This code should produce a spin animation for the div element.

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.
