Installation ------------ [](#installation) This extension is installable from various sources: 1. Via [Composer](https://packagist.org/packages/pagemachine/typo3-mail-css-inliner): ``` composer require pagemachine/typo3-mail-css-inliner ``` 2. From the [TYPO3 Extension Repository](https://extensions.typo3.org/extension/mail_css_inliner/) After installing the extension registers itself automatically, no further configuration is necessary. Purpose ------- [](#purpose) Designing mails is hard. Especially requirements like table layouts and inline styles are complicated to handle and take a lot of time to get right. This extension takes one burden off your shoulders and takes care of turning a regular stylesheet to inline styles. See our blog post about [Mail styling in TYPO3 now easier](https://www.pagemachine.de/blog/mail-styling-typo3/). Before: ``` CSS Inline Test body { color: #333; } h1 { font-size: 36px; } a { color: #337ab7; } Headline Content with link. ``` After: ``` CSS Inline Test body { color: #333; } h1 { font-size: 36px; } a { color: #337ab7; } Headline Content with link. ``` Currently only `` elements are supported, external styles via `` are not imported. Testing ------- [](#testing) All tests can be executed with the shipped Docker Compose definition: ``` docker compose run --rm app composer build ``` ### Health Score 59 — FairBetter than 98% of packages Maintenance88 Actively maintained with recent releases Popularity34 Limited adoption so far Community13 Small or concentrated contributor base Maturity84 Battle-tested with a long release history Bus Factor1 Top contributor holds 90.6% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
