csp_inline_styles - Twig Filter
Info
This feature is available in Contao 5.3 and later.
This filter extracts all inline CSS style attributes of a given HTML string or attributes object and automatically adds
CSP hashes for those to the current response context. The list of allowed styles can be configured in
contao.csp.allowed_inline_styles.
This is useful for rich text editor fields for example, if your editor configuration allows setting some inline styles (like colours for example).
Within Contao this is used by default for the TinyMCE output in the _rich_text template component.
