Slider Excerpt Length, Height

Theme: Graphene Theme (latest)
Site: https://www.anonyrev.com/

The slider is displaying things differently depending on the paragraphing that is used in a post.

I’m using the following code to set a limit on the words displayed in a slider but unfortunately this doesn’t take the paragraphs into account as you can see in the following images.

function graphene_custom_slider_excerpt_length(){
   graphene_set_excerpt_length( 35 );
}
add_action( 'graphene_before_slider', 'graphene_custom_slider_excerpt_length' );

Is there a way to also set a height limit for the transparent background? Basically I want it to be the same height for all previewed posts. The height should have a higher priority than the limit of words.

I hope you know what I’m talking about.

Thanks in advance!
