=====================================================
|
|
Breaking: #61471 - EXT:t3skin CSS files moved to less
|
|
=====================================================
|
|
|
|
See :issue:`61471`
|
|
|
|
Description
|
|
===========
|
|
|
|
All CSS files in EXT:t3skin are moved to less files and handled by less CSS pre processor
|
|
and merged to a single CSS file.
|
|
|
|
|
|
Impact
|
|
======
|
|
|
|
Single CSS files can not be included anymore. This may result in broken layouts.
|
|
|
|
|
|
Affected installations
|
|
======================
|
|
|
|
A TYPO3 instance is affected if an extension loads single CSS files from EXT:t3skin. Backend modules of
|
|
extensions usually get CSS core stuff loaded by default, which will not be a problem. An extension is
|
|
only affected if single CSS files are explicitly referenced. This should be a rare case.
|
|
|
|
|
|
Migration
|
|
=========
|
|
|
|
Most simple solution is to copy over the "old" CSS file from an older instance. Directly including those
|
|
files from t3skin is discouraged. A better solution is to refactor the extension to use the full t3skin
|
|
CSS file and to overlay it with required changes in an own file.
