Subject: [PATCH] view: favor whitespace wrap in <head>
Date: Fri, 25 Dec 2015 12:06:30 +0000 [thread overview]
Message-ID: <20151225120630.14664-2-e@80x24.org> (raw)
In-Reply-To: <20151225120630.14664-1-e@80x24.org>
If we bite the bullet and rely on inline CSS, we might as well
only specify it once per page instead of inline in every <pre>
tag which may handle UGC. So this actually saves us a small
amount of bandwith on most pages which have multiple <pre>
start tags.
