How to add class to teaser P? In Drupal 8, how can I add a class to teaser p html tag. I want to style the paragraph in teaser only, not when whole content is shown.
We can style that with simple css,

.node--view-mode-teaser .node__content p {
  /* write you style */
}


I think, you don't need to add separate class in P tag for that. and it would also affect only the teaser mode content :)
