:not() psuedoclass for httml[lang] not working

Trying to make a more dynamic css so do certain styling for non english html pages, instead of having to add a css rule each time a language page is added.

Trying to turn this...

html[lang='de-DE'],html[lang='pt-br'],html[lang='ja'] {      // bootstrap blocks flexbox fix      .col-12.d-flex > div:first-child {          display: flex;      }  }  

To work with this...

:not(html[lang='en-US']) {      // bootstrap blocks flexbox fix      .col-12.d-flex > div:first-child {          display: flex;      }  }
