CSS icons add visual clarity to navigation links, buttons, badge indicators, and action cards. Web icons are integrated using SVG vector icons or font icon libraries like Font Awesome.
Modern web applications embed icons using inline SVG or CSS font icon classes:
<!-- Method 1: Inline SVG Vector Icon (Recommended) -->
<svg class="icon" width="24" height="24" viewBox="0 0 24 24" fill="none" stroke="currentColor">
<path d="M5 12h14M12 5l7 7-7 7" stroke-width="2" stroke-linecap="round"/>
</svg>
<!-- Method 2: Font Icon Library (Font Awesome) -->
<i class="fa-solid fa-envelope"></i>
/* Style SVG icons dynamically with CSS */
.icon {
width: 1.25rem;
height: 1.25rem;
vertical-align: middle;
color: #38bdf8;
transition: transform 0.2s ease;
}
.icon:hover {
transform: translateX(4px);
}
