Sliders

I am building local and a novice at coding but with your resources and help i am doing quite well with my first wordpress site using Customizr theme.

I have set a multisite with three (3) child themes. I have sliders (theme built in) on a couple of pages in the child themes.

What i want to do is, i would like to set the sliders to different heights on the various pages.

Please help me achieve this.

Thank you.
