Laravel Mail CSS Inliner

Why?

Most email clients won't render CSS (on a <link> or a <style>). The solution is inline your CSS directly on the HTML. Doing this by hand easily turns into unmantainable templates. The goal of this package is to automate the process of inlining that CSS before sending the emails.

Installation and compatibility

Starting with version 5 this package requires PHP 8.0 and Laravel 9.0 or higher.

Using an older version of PHP / Laravel?

If you are on a PHP version below 8.0 or a Laravel version below 9.0 just use version 4.* of this package.

How?

Using a wonderful CSS inliner package wrapped in a Symfony Mailer plugin and served as a Service Provider it just works without any configuration. Since this is a Symfony Mailer plugin, it will automatically inline your css when parsing an email template. You don't have to do anything!

Turns style tag:

<html>
    <head>
        <style>
            h1 {
                font-size: 24px;
                color: #000;
            }
        </style>
    </head>
    <body>
        <h1>Hey you</h1>
    </body>
</html>

Or the link tag:

<html>
    <head>
        <link rel="stylesheet" type="text/css" href="./tests/css/test.css">
    </head>
    <body>
        <h1>Hey you</h1>
    </body>
</html>

Into this:

<html>
    <head>
        <style>
            h1 {
                font-size: 24px;
                color: #000;
            }
        </style>
    </head>
    <body>
        <h1 style="font-size: 24px; color: #000;">Hey you</h1>
    </body>
</html>

Installation

This package needs Laravel 9.x.

Begin by installing this package through Composer. Require it directly from the Terminal to take the last stable version:

composer require fedeisas/laravel-mail-css-inliner

At this point the inliner should be already working with the default options. If you want to fine-tune these options, you can do so by publishing the configuration file:

php artisan vendor:publish --provider='Fedeisas\LaravelMailCssInliner\LaravelMailCssInlinerServiceProvider'

and changing the settings on the generated config/css-inliner.php file.
