You realize the main page code is completely broken, right? There's a hanging comment tag that eats up the end tags for a bunch of stuff. The changes I made also get rid of the random white space and properly separate content into two columns. Maybe you should actually compare the page before I edited and page after I edited instead of reactively reverting the changes.
I don't really know what you're talking about with the hanging comment tag and that the main page's code is completely broken, because on my computer the main page looks just fine and when you removed those white spaces everything started to look messy. I actually looked at your edit before I changed it. It's not like I would undo it because it looked good.
I have a 23 inch widescreen monitor, my screen resolution is 1920x1080, I'm not zoomed out at all. I really doubt only 10% of people have resolutions as high as mine, considering my monitor isn't even considered that big.
Regardless, whatever you did makes it look a lot better on my screen. Good work.
