Cross-Browser Normalization of CSS3 Transition End Events
In web development, handling transition end events across different browsers can be a challenge due to browser inconsistencies. Browsers such as WebKit, Firefox, and Opera use distinct event names for this purpose, creating a need for cross-browser normalization.
There are several approaches to address this issue:
- Browser Sniffing: Detecting the browser type and assigning the appropriate event name. However, this method is not reliable as new browsers may introduce new events.
- Individual Event Listeners: Adding separate event listeners for each browser-specific event. While this approach is more comprehensive, it can lead to code bloat and maintenance issues.
A more elegant solution involves utilizing a JavaScript function that dynamically determines the appropriate event name. This technique harnesses the concept of feature detection employed by the Modernizr library:
function transitionEndEventName() {
var el = document.createElement('div'),
transitions = {
'transition':'transitionend',
'OTransition':'otransitionend',
'MozTransition':'transitionend',
'WebkitTransition':'webkitTransitionEnd'
};
for (var i in transitions) {
if (transitions.hasOwnProperty(i) && el.style[i] !== undefined) {
return transitions[i];
}
}
}
This function iterates through all supported transition properties and returns the corresponding event name. Once obtained, you can simply use this function to assign the event listener:
var transitionEnd = transitionEndEventName(); element.addEventListener(transitionEnd, theFunctionToInvoke, false);
By utilizing this approach, you can normalize the handling of transition end events across browsers, ensuring consistent behavior and simplifying your code.

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.
