Which code are you referring to? I think you may need to review just exactly what a child theme is and how it works. Please look at the following links:

or you can do a search for yourself: wordpress child themes
there are a ton of how to’s and tutorials. Keep in mind that they apply to all child themes
If you are referring to css then you need to find the element you want to style and add it to your child theme css. Your child theme css is pulled in first before the parent theme, so any changes you make in the child theme come first.
So for example, lets assume you want to add colors to the main container that wraps around the header. You would look for .header_container in the parent style css. When you find it you will notice it looks like this:
/* main containers */
.header_container,
.nav_container,
.content_container,
.sidebar_container,
.footer_container {
background-color: transparent;
max-width: 100%;
width: 100%;
}
So the .header_container background color is set to transparent, but you want it to be blue. So you open up your child theme style sheet and add the following:
.header_container {
background-color: blue;
}
Now the .header_container will have a background color of blue.
Now if you want to change something in the header, lets say for example you want to add some code, you would copy header.php from the parent theme into the child theme. Then you would add your code.
Hope this made sense. I suggest you review anything and everything you can on child themes and how to use theme.
