Use Font Awesome Icons as CSS Content
In using Font Awesome icons as CSS content, avoid embedding HTML code directly within the content property. Instead, follow these steps:
FontAwesome 5:
- Define the font family as "Font Awesome 5 Free" or "Font Awesome 5 Brands" depending on the icon type.
- Use the Unicode escape code instead of HTML entities for the icon, e.g., "f095" for "fa-phone".
- Ensure the font weight is set to 900.
a:before {
font-family: "Font Awesome 5 Free";
content: "\f095";
display: inline-block;
padding-right: 3px;
vertical-align: middle;
font-weight: 900;
}
FontAwesome 4 and Below:
- Copy the content property with the corresponding entity from the Font Awesome style sheet.
- Use the copied content within the content property with the correct font family.
a:before {
font-family: FontAwesome;
content: "\f095";
}
For spacing between the icon and text:
- Set display: inline-block; for the icon to prevent overlap.
- Add padding-right: to provide space between the two.
a:before {
font-family: FontAwesome;
content: "\f095";
display: inline-block;
padding-right: 3px;
vertical-align: middle;
}
To change the icon on hover:
- Create a separate selector for the :hover state.
- Modify the content property to specify the new Unicode escape code for the hover icon.
a:hover:before {
content: "\f099";
}
Consider setting a fixed width on the base icon declaration to prevent nudging due to different icon sizes.

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.
