Colour lines settings and testimonials

Hey!

My website is using Agave portfolio theme.

  1. I’m trying to change the color of the line under the active header (see screenshot). Can someone tell me how to do so? The same applies to the lines in between questions of the contact form.


  2. I’m using the testimonial option (see Ervaringen on website) from the theme. However, the row seems to be to short to show the full testimonial in one page. Is there a way to change this so all testimonials appear completely?

Thank you so much in advance!
