Twenty Eleven: comment alignment problems

Greetings,

I’ve created a child theme based on twenty eleven, and am having difficulties aligning the comment author name and date. An example of this can be seen here:

https://www.gravelbike.com/?p=5655#comments

I want to align the author’s name and the date with the comment text/body. It doesn’t appear to be as simple as adding align-text attributes, so I’m stumped.

I did make changes to the sizes of margins, primary, content, and secondary (see below), so I’m wondering if there’s a potential conflict there.

Thanks!

@import url('../twentyeleven/style.css');

.entry-title {
	text-align: left;
	clear: both;
	color: #222;
	font-size: 26px;
	font-weight: bold;
	line-height: 1.5em;
	padding-bottom: .3em;
	padding-top: 15px;
}

.entry-title,
.entry-header .entry-meta {
	text-align: left;
}

.comment-content p {
	text-align: left;
}

body {
	padding: 0 1em;
}
#page {
	margin: 2em auto;
	max-width: 1100px;
}
#branding hgroup {
	margin: 0 7.6%;
}
#access div {
	margin: 0 7.6%;
}
#primary {
	float: left;
	margin: 0 -33.9% 0 0;
	width: 100%;
}
#content {
	margin: 0 34% 0 2.5%;
	width: 62%;
}
#secondary {
	float: right;
	margin-right: 2.5%;
	width: 27%;
}
