Unable to resize components in AEM site
I am using AEM 6.4 version and I am totally new to AEM.
I am trying to develop a website following the steps given in the below link.
Getting Started Developing AEM Sites - WKND Tutorial
I am in part 4 of the tutorial (Getting Started with AEM Sites Part 4 - Developing with the Style System)
My problem is that the layout and other components snaps back into place no matter where I drag it at all times.i have tried in different browsers as well. I am not able to resize any of the components. But suprisingly , i was able to resize the components before two days.
Can anyone help me with this please
