Change email css theme at runtime - Laravel

Question

According to documentation, to change email css, simply write a new CSS file within the html/themes directory and change the theme option of your mail configuration file.

In my application has two locales. each locale has different css style. my question is: how to change the css theme at runtime according to app locale?

Answer 1

This works with Laravel 5.7

Assuming you have in /resources/views/vendor/mail/html/themes/ multiple css files:

themes
 >default.css
 >funky_table.css 

you can set the theme in you build method.

public function build()
    {
        $this->theme = 'funky_table';
        return $this->markdown(...

This will also work for queries.
