i need to change color of email adress in post

[please don’t bump]

at the moment these email links are styled in style.css with:

body #content a:hover {
	color: #b49f09;
}

body #content a, body #content a:visited {
	color: #677714;

to make it more specific for the post/page content, add some styles like these to style.css of your theme:

body #content .entry-content a:hover {
	color: #b49f09;
}

body #content .entry-content a, body #content .entry-content a:visited {
