Under links in posts without underlining links in menu

Hi.

I want to know how I can add color and an underline to all the links in posts without adding color and an underline to the links in my menus.

Here’s a post I’m working on so you can see the problem: https://heresyourcoffee.com/496/. Notice that the links in the menu are not underlined and the links look like regular text in the post.

I have found a place in the css where I can add code to underline the links. I thought that adding code here for color would also turn the links blue.

When the code is added, the links in my posts and the links in the menu are underlined. And the links in the post remains black.

I need to turn off the underlines in the menu, keep them in the posts and turn the anchor text blue.

Any idea how to do it?

Thanks.
