Themes

Add your theme in the user form

Edit src/Form/ProfileType.php:

->add('theme', ChoiceType::class, [
    'label' => 'Theme',
    'choices' => [
        'Default' => 'default',
        'Dark' => 'dark',
        'Cool Theme' => 'cool',
    ],
])

Override templates

You can overwrite all the original templates by adding a file with the same structure under your theme directory:

In templates/themes/<your theme>/[original_folder]/[original_template_name] you can rewrite the template with your theme markup

Every time a template is called, it will first check if the template exists in the theme’s folder or fall back to the original one

Update CSS assets

Test the theme

Don’t forget to change your theme in the user settings to test it.
