Images on Feature Circles and length of menu bar

Hi,

I am a novice to customizr. I have spent the entire morning trying to figure out how to change the images on the feature circles. In the process, I created a child theme, but it gives me an error: “The parent theme is missing. Please install the ” customizr ” parent theme.” I have three questions:

1. how to change the images on the three circles?
2. how to change the width of the header menu? you can see it at dreamitcreateitliveit.com
3. How to correct the child theme error? ( i did create a folder under themes, called it customizrchild and placed style.css with the following code in it)
/*
Theme Name:???? Customizr Child??
Theme URI:??????https://mysite.com/
Description:????Customizr Child
Author:???????? Gia????????????????
Author URI:???? https://mysite.com/
Template:?????? customizr??????
Version:????????1.0.0????????????
*/

@import url(“../customizr/style.css”);
