Trouble adding new style elements

[DavidJay]

I am new to CSS but have read about specificity and thought I understood it but something is obviously not clicking.

I am trying to modify the appearance of some items on a custom taxonomy template and having some troubles. In Chrome Inspect Element it shows my new CSS class/ID but the values do not override the parent values.

Here is a sample of the code:

default for the child theme

h1,
h2,
h2 a,
h2 a:visited {
	color: #444;
	font-family: 'Droid Sans', Tahoma, Verdana;
	font-size: 30px;
	line-height: 36px;
}

My addition

.taxonomy-template h2,
.taxonomy-template h2 a,
.taxonomy-template h2 a:visited {
	font-size: 20px;
	font-weight: bold;
	margin: 5px 0 2px 0;
	padding: 5px;
}

Any CSS experts see what I am missing?
