// Browsers support SVG favicons $this->addHeadLink(HTMLHelper::_('image', 'joomla-favicon.svg', '', [], true, 1), 'icon', 'rel', ['type' => 'image/svg+xml']); $this->addHeadLink(HTMLHelper::_('image', 'favicon.ico', '', [], true, 1), 'alternate icon', 'rel', ['type' => 'image/vnd.microsoft.icon']); $this->addHeadLink(HTMLHelper::_('image', 'joomla-favicon-pinned.svg', '', [], true, 1), 'mask-icon', 'rel', ['color' => '#000']);

This code adds multiple favicon-related <link> elements to the HTML <head> section of a webpage. These links specify different icon formats for the website's favicon, catering to various browser preferences and capabilities. Here's a breakdown of each line:

  1. SVG favicon support:

    $this->addHeadLink(HTMLHelper::_('image', 'joomla-favicon.svg', '', [], true, 1), 'icon', 'rel', ['type' => 'image/svg+xml']);
    • This adds a <link> element for an SVG favicon (joomla-favicon.svg).
    • The rel attribute is set to icon.
    • The type attribute specifies image/svg+xml, denoting the SVG format.
    • SVG favicons are scalable and supported by modern browsers.

  2. Fallback favicon for older browsers:

    $this->addHeadLink(HTMLHelper::_('image', 'favicon.ico', '', [], true, 1), 'alternate icon', 'rel', ['type' => 'image/vnd.microsoft.icon']);
    • This adds a <link> element for an ICO format favicon (favicon.ico), which is commonly used and supported by older browsers, particularly Internet Explorer.
    • The rel attribute is set to alternate icon, signifying an alternative favicon.
    • The type attribute specifies image/vnd.microsoft.icon, identifying the ICO format.

  3. Pinned tab favicon for Safari:

    $this->addHeadLink(HTMLHelper::_('image', 'joomla-favicon-pinned.svg', '', [], true, 1), 'mask-icon', 'rel', ['color' => '#000']);
    • This adds a <link> element for a pinned tab favicon (joomla-favicon-pinned.svg) in Safari.
    • The rel attribute is set to mask-icon, indicating it is used for Safari's pinned tabs.
    • The color attribute defines the monochromatic fill color for the pinned icon.

Summary:

The code ensures the website's favicon is compatible with modern browsers (SVG), older browsers (ICO), and Safari pinned tabs (mask icon). It improves cross-browser support and offers optimal user experience with favicons.
