UI enhancement of landing page

The current landing page does not match the theme colors of the site like in the join room.

Describe the Solution You'd Like: I am proposing a rebuild of the UI for the current landing page based on the theme colors of the site. We already have the color schemes finalized which have been used in the Join Room Page also.

After the Update, the UI will be responsive and it will match the color scheme of the site

Fixing the UI on the room page

Some issues with the UI on the room page need to be fixed

1. The tools section is taking too much space than required which needs to be fixed and the canvas should acquire more space.
2. Apart from that the chat popup box should not have a scrollbar
