Facebook goes for a design tweaks

• Way of providing feedback on Ads has been changed - The Thumbs up / Thumbs down option has been replaced with Like/X. What this change does is that it allows you to provide feedback for the ads using the same language that you are used to for providing your feedback on other Facebook content such as liking a link that your friend has shared with you.

• No more rounded corners – The era of rounder corners has come to an end and square corner roots are part of the new visual style.
• Facebook Header now covers the full screen width – Yup the Facebook team has extended the blue facebook Header to fill the entire screen. Plus, the layout of the items content in the header have slightly been modified.
