UPDATE:
Oh boy. I just realized that my lame laptop can only have a resolution up to 1280 x 800. Ugh. No wonder the height-width dimensions are so messed up. >.< I can't increase it any further based on the limitations of this machine...
But anyway, I guess I can deal with the featured card being slightly cut off by the special 'Featured Articles' tab thingy. Hopefully no one else has the same problems I do. ^^;
Resolution is not the problem here because it doesn't really effect how the page is built. The problem here is that for some reason your browser makes the Featured Articles slider too big.
Like I said, unfortunately I have no idea what could cause this, nor do I know how to fix it. The design should be very basic so it shouldn't break down.
If someone else has this same problem, please let me know. Maybe then we would get more evidence to help fix this.
