I am redesigning a website, http://www.aljoufilaw.com, and I have some concerns about different screen resolutions. The website lay-out changes when viewed in different screen resolutions and my client does not want this, i.e, horizontal scroll bar. I tried to view the website in 1024x768 resolution and it does not look good, however, if you view it in 1366x768, it looks okay.

I really appreciate your suggestions and opinions why does this happen and how can i solve this.
