I’m trying to change the page width of my blog which is using the triton lite theme. I took help of fire bug and edited the page width to my liking. How ever when i replicate the changes to my style.css file, the changes are not taking effect. I tried clearing the cache, using a different browser and even restarting my computer. But still the changes do not take effect. What am i doing wrong? Can anyone help? This is my blog. thereddotman.com
