 * hello everyone.
    i am creating my own theme and i am trying to set a max-width
   and max-height for post thumbnails in functions.php i found this php tag: `set_post_thumbnail_size(
   80, 80, false);`
 * but i want to use max measures not fixed ones..
    is there any way to include 
   CSS inside that php tag ? i already have this in my css file :
 *     ```
       .post-thumbnail, .attachment-post-thumbnail {
           max-height: 300px;
           max-width: 540px;
       }
       ```
   
 *  but since it is a post thumbnail they add html `height="" width=""`
 * any help is kindly appreciated !

 * thank you **andrew** for the quick reply.
    i did that and it still adds this :`
   <img width="1920" height="1200" src="//" class="attachment-post-thumbnail wp-
   post-image" alt="//">` i want to use CSS only ( `class="attachment-post-thumbnail"`),
   so how can i get rid of `width="1920" height="1200"` thank you sir 🙂

 * The exact solution was this:
 *     ```
       .post-thumbnail,
       .attachment-post-thumbnail {
           width: auto;
           height auto;
       }
       ```
   
 * If you’re not creating your own theme then I don’t think you have the exact problem.
