CSS background
.icon-shield-2 {

width: 24px;
height: 24px;
}React (with @iconify/react)
import { Icon } from '@iconify/react';
<Icon icon="streamline-flex:shield-2" width="24" />Recolouring Flex free icons icons
Flex free icons icons use currentColor, so changing colour is a one-line CSS rule. Set color on the parent element and the icon adopts it. This makes the set easy to theme for light mode, dark mode, and brand colour accents.
Search engine–safe usage
Always include a meaningful alt attribute on <img> tags or an aria-label on inline SVGs. For purely decorative icons (where text already conveys the meaning), use alt="" so screen readers skip them.
