How to change Header and body font

[jinuralite]

Can someone help me please?

I have coded in a custom Avenir Bold font into my website and it changed both header and body fonts.

I want the body font to be Avenir Light and the Header to be Avenir Bold throughout the whole website - How do I do this?

You need to change the font weight. By default body cover for all elements. If you want to change the header or other elements you need to set font weight to that specific element. For example

.header{font-weight:700} // bold
