Bold text but only in articles

Hi there,

I tried making links on my articles (both pages and posts) appear bold. I used the following code:

#content a, a:not(.button) {
    font-weight: bold !important;
}

But it made all links bold like meta data link, link in the post navigation etc.

I tried using this code too:

p a:link, p a:hover, p a:active, p a:visited, a:not(.button) {
    font-weight: bold !important;
}

But it too had the same effect.
I want something that only makes the text links inside the article bold. No other links (buttons, post meta, navigation, etc).

Thank you,
