This is a paragraph. It is justify aligned. It gets really mad when people associate it with Justin Timberlake. Typically, justified is pretty straight laced. It likes everything to be in it's place and not all cattywampus like the rest of the aligns. I am not saying that makes it better than the rest of the aligns, but it does tend to put off more of an elitist attitude.
This is a paragraph. It is right aligned. It is a bit more conservative in it's views. It's prefers to not be told what to do or how to do it. Right align totally owns a slew of guns and loves to head to the range for some practice. Which is cool and all. I mean, it's a pretty good shot from at least four or five football fields away. Dead on. So boss.
The image above happens to be centered. The caption also has a link in it, just to see if it does anything funky.
This is a paragraph. It is left aligned. Because of this, it is a bit more liberal in it's views. It's favorite color is green. Left align tends to be more eco-friendly, but it provides no concrete evidence that it really is. Even though it likes share the wealth evenly, it leaves the equal distribution up to justified alignment.
And now for a massively large image. It also has no alignment.
The image above, though 1200px wide, should not overflow the content area. It should remain contained with no visible disruption to the flow of content.
