Please help me configure my blog

Tweet

Hello, I own a blog hosted by Blogger and I have used several HTML codes to customize it, like I have added two sidebars on either sides, I have a blog background and a custom header. I also removed the NaviBar. Check out my blog: http://technotreat.blogspot.com The problem with me is that the writing space, inbetween the sidebars is very less and just 5 or 6 words will turn you to a new line. This hinders my visitor's reading experience. Is there any way through which I can increase the reading space so as to squeeze in more words in my blog? Regards, AJ-Rox
