I am getting this error in Magento 2.3. Error occurs with every email sent. enter image description here

CSS inlining error: DOMXPath::query(): Invalid expression in selector >> .fotorama__wrap:not(.fotorama__wrap--toggle-arrows) .fotorama__fullscreen-icon << in /var/www/html/magento2/vendor/pelago/emogrifier/src/Emogrifier.php on line 502

I have tried this method:

adding this file in app/design/frontend/VendorTheme/default/web/css/email.less

@import 'source/lib/email/stand/_lib.less'; // Global lib
@import 'source/lib/email/stand/variables/_email.less'; // Global email variables

I have also tried adding

"pelago/emogrifier": "1.0.0 as 0.1.1" in composer.json
  • what is your php version ? May 2 '19 at 13:48
  • just downgrade the php version 7.3 to 7.2 every thing is working fine May 3 '19 at 6:22

I have got same error and solved as

Just copy these files:




and removed this line from both files '@import 'source/_theme.less'.

Cause by doing this we are separating theme css and email css.

Last run the following commands:

php bin/magento setup:upgrade
php bin/magento setup:di:compile
php bin/magento setup:static-content:deploy -f
  • this solution not working so please help me @Rohit Kaushik Dec 30 '19 at 6:08
  • have you removed _theme.less from both files? /vendor/magento/theme-frontend-blank/web/css/email.less /vendor/magento/theme-frontend-blank/web/css/email-inline.less Jan 3 '20 at 8:08

Please do not use in your css code selectors with :not(), especially if after another selector follows to ':not' .This is necessary to aviod Еmogrifier errrors

  • I had this &:not(:first-child) { in less and got this error too Invalid expression in selector >> .email-items tbody dl dt:not(:first-child) . Not sure if there is any other way to write same css. Apr 7 '21 at 6:08

    just write styles for all elements '.email-items tbody dl dt' and then write styles for element '.email-items tbody dl dt:first-child' separately. it would be better Apr 8 '21 at 7:18

I've managed to fix the issue, is not the best practice, but it works.

Go to Marketing > Email Templates and create a new template. Click on Load template and load Magento_Email > Header.

In the Template Content field remove this line:

{{inlinecss file="css/email-inline.css"}}

A better solution would be to fix the issue in the file above.


Another solution:

My PHP version: 7.2.32

composer require pelago/emogrifier:2.0.0

It was not working with pelago/emogrifier:2.2.0
