How Can I Hide Font Awesome Placeholder Icons Until the Font Loads?

Determining Font Load Status for Icon Display
Problem:
When utilizing Font Awesome, icons initially display with placeholder characters until the font files are loaded. To address this, the task is to conceal these placeholder icons during the loading process.
Solution:
To detect font file load status, leverage the jQuery-FontSpy plugin. This plugin evaluates font width discrepancies between the desired font and an arbitrary fallback font. If the widths match, the desired font remains unloaded; otherwise, it has successfully loaded.
Plugin Implementation:
- Include the jQuery-FontSpy script:
<script src="scripts/jquery-fontSpy.js"></script>
- Initialize plugin on the desired element:
$('.icon-container').fontSpy({
onLoad: 'fa-loaded',
onFail: 'fa-not-loaded',
});
- Define the styles for loading and failure states:
.fa-loaded {
display: block;
}
.fa-not-loaded {
display: none;
}
With jQuery-FontSpy, the icons will initially be hidden. Upon font load, the 'onLoad' class is applied, unhiding the icons. If the font fails to load, the 'onFail' class is applied, keeping the icons hidden. This plugin provides precise control over the icon display, ensuring an optimal user experience even before the font has loaded completely.

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.

What is the scope of a CSS Custom Property?
Jun 25, 2025 am 12:16 AM
The scope of CSS custom properties depends on the context of their declaration, global variables are usually defined in :root, while local variables are defined within a specific selector for componentization and isolation of styles. For example, variables defined in the .card class are only available for elements that match the class and their children. Best practices include: 1. Use: root to define global variables such as topic color; 2. Define local variables inside the component to implement encapsulation; 3. Avoid repeatedly declaring the same variable; 4. Pay attention to the coverage problems that may be caused by selector specificity. Additionally, CSS variables are case sensitive and should be defined before use to avoid errors. If the variable is undefined or the reference fails, the fallback value or default value initial will be used. Debug can be done through the browser developer
