Feature: #92616 - Bootstrap v5
|
|
==============================
|
|
|
|
See :issue:`92616`
|
|
|
|
Description
|
|
===========
|
|
|
|
TYPO3s Backend is powered with Bootstrap v5 (https://getbootstrap.com).
|
|
|
|
Previous versions ran with Bootstrap v3. A lots of changes and
|
|
improvements are included, especially regarding simplification
|
|
of building Layouts and Containers.
|
|
|
|
Backend modules which relied on Twitter Bootstrap v3 markup,
|
|
or functionality in JavaScript, will have a slightly different
|
|
and improved look & feel.
|
|
|
|
|
|
Impact
|
|
======
|
|
|
|
It is important during updates of custom backend modules
|
|
to study the Bootstrap Migration guidelines and adapt accordingly:
|
|
|
|
* https://getbootstrap.com/docs/4.5/migration/
|
|
* https://getbootstrap.com/docs/5.0/migration/
|
|
|
|
TYPO3 Core still includes some legacy styling and functionality
|
|
to provide compatibility, but backend markup and code will
|
|
be adapted during further TYPO3 v11 development to simplify
|
|
the HTML and CSS code shipped with TYPO3 Core.
