Breaking: #98312 - TypoScript setting page.CSS_inlineStyle removed

Description

The TypoScript setting page.CSS_inlineStyle which was used to inject an inline CSS string into the TYPO3 Frontend has been removed.

Impact

Using this setting has no effect anymore since TYPO3 v12.

Affected installations

TYPO3 installations having this option set in their TypoScript setup.

Migration

Use page.cssInline instead, which has been around for many TYPO3 versions already.

The superior setting page.cssInline allows to use stdWrap and cObject.

Example for migration:

page.CSS_inlineStyle = a { color: red; }

page.cssInline.100 = TEXT
page.cssInline.100.value = a { color: red; }
