Discover the CSS cap unit: a powerful tool for precise typographic alignment! One cap unit equals the height of a capital letter in the current font. This is particularly useful for aligning icons with text, as demonstrated below.
HTML & CSS
Here's how to use it: Set the icon's height to 1cap for seamless integration with adjacent text, such as within buttons. The example below uses flexbox for easy alignment.
<div class="container"> <img class="icon" src="gear-icon.svg" alt="Gear Icon"> <h3>CSS</h3> </div>
.container {
display: flex;
align-items: baseline; /* Aligns items to the baseline of the text */
gap: 0.5rem; /* Adds spacing between icon and text */
}
.container .icon {
height: 1cap;
aspect-ratio: 1; /* Maintains the icon's aspect ratio */
}
This technique ensures consistent vertical alignment regardless of font size changes, resulting in cleaner and more professional-looking layouts.

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.
