Matching the First Element of a Specific Type in the Entire Document
Problem:
How can you apply :first-of-type styling to the first element of a particular type anywhere in the document, regardless of its parent element?
CSS Limitations:
CSS's :first-of-type pseudo-class only selects the first sibling of a specific type within its parent element, not across the entire document.
JavaScript Solution:
:first-of-type Class Addition:
- Add a "first-of-type" class to the first matching element using JavaScript's querySelector() method.
- Apply styling to elements with the "first-of-type" class.
Example:
document.querySelector('p').className += ' first-of-type';
p {
background: red;
}
p.first-of-type {
background: pink;
}
<body>
<section>
<p>111</p>
<p>222</p>
<p>333</p>
</section>
<p>444</p>
<p>555</p>
</body>
This solution ensures that the first paragraph in the entire document, regardless of its location, receives the "first-of-type" styling.

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.
