Color & Font change in menu

I have a couple of questions. A couple of questions related to the below screen shot.

1. How do I change all the breadcrumbs for the site to Arial font?
2. How do I change the color of the bright blue highlighted tab & the bright blue triangular shape to whatever I want?


Thank you,

 

Hello,

Paste this code in Custom CSS
Appearance > Theme Option > Styling Option > Custom CSS

The following code will change the font of your breadcrumb

Code:

.page_heading_container .page_heading_content {
font-family: Add your font name;
}

The following code will change the background color of breadcrumb, You can change the color value according to your requirement

Code:

.page_heading_container {
background: red!important;
}

And the small triangle below the breadcrumb is an image if you want to change to your desired color then you can change it with the help of photo editing tool.
You will get the image in "images" directory of your theme.
