The degraded browser experience is a self-contained skin that appears when a user tries to view a MindTouch site in a browser that is no longer supported. When your site is viewed in an unsupported browser, all users are treated as anonymous users, i.e. they will only be able to view content.
The legacy browser experience will appear for anyone who views your site in Internet Explorer 8, 9, or 10. Users who view your site with modern browsers will still get your default MindTouch experience.
The simplified skin for the legacy browser experience has no pro member functionality or page thumbnails but allows for a limited amount of custom branding which will have to be added to your regular branding.
Your pro member users will receive the below message informing them that their advanced functionality is no longer accessible. All other user types will be redirected to the new skin without any messaging about the legacy browser experience.
Because most legacy browsers do not support different variations of CSS, the CSS you've applied to your header and footer will be stripped out. Instead, custom CSS can be configured separately through your control panel. Administrators will see the legacy browser CSS at the bottom of their Custom Site CSS page.
You can then use this to apply any legacy browser specific CSS in order to brand your site for your legacy browser experience. If you're unsure about whether certain types of CSS are used, caniuse.com is a great resource which will inform you of supported CSS properties on legacy browsers.
How the user experience is affected
Branding and images
The ability to log in, register and reset your password still exists in the new skin but will not display content or features differently based on user type. This means that your site's single sign-on (SSO) will still work.
Restricted pages and conditional content
All users will see the content of your site as anonymous users would. Users viewing your site in an unsupported browser, will not be able to see restricted pages, even if they are pro members. Conditional content will not be rendered.
Your users will be able to navigate your site through the use of user interface (UI) elements such as the MindTouch structured framework, search, breadcrumbs, and previous and next pagination. Header and footer templates are rendered specifically for this legacy experience.
All versions of the MindTouch framework have been styled in this skin so that it can be used across all skins. If your site doesn't use the MindTouch structured framework, then your users will have difficultly navigating through your hierarchy unless you provide them with navigation through your legacy browser header/footer templates or content pages.
Article pages in the legacy browser experience contain many of the same elements that they do in your regular MindTouch site such as the page title, last updated, table of contents, back to top link, and previous and next pagination. Social share, PDF generation, related articles, and article feedback are not available through the unsupported browser.
