Creates CSS files for legacy browsers that don't support CSS custom properties (https://developer.mozilla.org/en-US/docs/Web/CSS/Using_CSS_custom_properties).
For more information see <see href="https://YetaWF.com/Documentation/YetaWF/Topic/g_dev_cssvariables">CSS Custom Properties.</see> This is mainly used to support IE11 and older. By default this is not used in YetaWF.
When using Bootstrap 4 in a skin, AppSettings.json, Application:P:YetaWF_Core:SupportLegacyBrowser can be set to true to support IE11. Otherwise, any request by IE 11 (and lower) will be redirected to a customizable "Unsupported Browser" page (/Maintenance/Unsupported Browser.html). The default skins in YetaWF use Bootstrap 5. Bootstrap 4 is only available in custom skins.
