Fading Background Images with jQuery
Background images are a common way to add visual interest to web pages or apps. However, you may want to transition between multiple background images to create a dynamic effect.
Traditionally, jQuery's fadeIn and fadeOut functions only work on elements with background colors. This presents a challenge when attempting to fade background images without creating new HTML elements for each image.
Solution:
To overcome this limitation, a common workaround is to use tags for your images and hide them initially using display:none. By positioning the images absolutely, with a negative z-index, you can make them behave like backgrounds. Here's a step-by-step solution:
-
Convert your background images to
tags:
<code class="html"><img src="image1.jpg" /> <img src="image2.jpg" /></code>
-
Style the images using CSS:
<code class="css">img { position: absolute; z-index: -1; display: none; }</code> -
Use jQuery to fade the images in and out:
<code class="javascript">function test() { $("img").each(function(index) { $(this).hide(); $(this).delay(3000 * index).fadeIn(3000).fadeOut(); }); } test();</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.
