Can Child Elements Override the CSS `text-decoration` Property?
Dec 31, 2024 am 09:32 AM
Overriding CSS text-decoration Property in Child Elements
In CSS, certain properties can be overridden by child elements, while others cannot. The text-decoration property falls into the latter category.
When applied to a parent element, text-decoration affects the entire element, including any descendant elements. This means that child elements cannot override the text-decoration property of their ancestors.
According to the CSS text-decoration specification:
"The 'text-decoration' property on descendant elements cannot have any effect on the decoration of the ancestor."
This is because text decorations are drawn across the entire parent element, ignoring any descendant elements.
Understanding Overridable Properties
CSS properties that can be overridden by child elements generally fall into the following categories:
- Font properties (e.g., color, font-family)
- Size and position properties (e.g., width, height, margin)
- Visibility properties (e.g., display, visibility)
Properties that cannot be overridden by child elements include:
- Inline formatting properties (e.g., text-transform, text-decoration)
- Background properties (e.g., background-color, background-image)
- Border properties (e.g., border-color, border-width)
CSS3 text-decoration-skip Property
In CSS3, a new property called text-decoration-skip was introduced to address limitations with text-decoration overriding. This property allows child elements to skip over specific types of text decoration applied to their ancestors.
For example:
span {
text-decoration-skip: underlines;
}
By setting text-decoration-skip to "underlines", the span element will skip any underlined text decoration applied to its parent 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.
