Automatically for all Mercury websites:Update to Bootstrap 5

Bootstrap 5 ensures that future developments of the template can benefit from the latest CSS features. The change automatically affects all existing websites that use the Mercury template.

Bootstrap 5 offers various new features, including:

XXL screen size added

With XXL, Bootstrap 5 supports an additional screen size. This allows more content to be displayed on large desktop screens. This additional screen size is automatically available on all web pages. 

Using CSS Custom Properties

Bootstrap 5 utilizes modern web design techniques such as CSS custom properties. Often referred to as CSS variables, these make designing with CSS much easier for agencies.

No more support for Internet Explorer

Bootstrap 5 no longer supports Internet Explorer. This browser is now obsolete and is no longer being developed by Microsoft due to various security vulnerabilities—in favor of Edge.

Careful attention has been paid to ensuring that existing Mercury sites are displayed in exactly the same way as before the conversion. There may be minimal differences in details, but these should be improvements. If, after the conversion, the display of a Mercury site has changed significantly for the worse, please inform Alkacon Software or your OpenCms administration.
