Nov 03, 2024 am 04:05 AMHover Effect on Parent and Child Elements
To address the challenge of disabling a parent element's hover effect when the cursor moves over a nested child element, let's consider the following solution:
CSS :has Selector (introduced in 2024)
With the introduction of the CSS :has selector, you can directly style a parent element based on the hover state of its child. For example:
.parent:has(.child:hover) { background: normal; }
This code ensures that when the cursor hovers over the child element with the class "child," the background color of the parent element with the class "parent" returns to its original state.
Sibling Element Trick
Prior to the :has selector, a workaround was to use a sibling element:
<div class="parent"> <div class="sibling"></div> <div class="child"></div> </div>
The sibling element is positioned using absolute positioning to overlap the child element. When you hover over the child element, the sibling element's hover effect is activated, overriding the parent element's hover effect.
.child:hover ~ .sibling { background: #FFF; // Override parent's background color }
Limitations
Note that these solutions rely on the structure of the nested elements and may not work in all cases.

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.

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.

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.
