Answer 3

Chris C. Thank you..
The resize property meets the requirements somehow but it can only allow to resize from bottom corner, I wanted it to resize from any where in the right side. So, after long research I concluded it is difficult for me to implement this feature from scratch as a beginner and more harder to implement it with touchscreen support. so, I found a library called [split.js](https://split.js.org) which am trying to setup, and it is working as expected by me..
