Enhancement of the redesigned welcome site

[Ishikabaid]

We are redesigning the welcome site and the basic design is implemented here but there are a few things which we need to fix in order to implement the whole design successfully.

1. Right now there is a horizontal scroll on the site, we need to remove that.

2. We need to remove the underline on check them out text and align it with the adjacent arrow symbol, see the image below for the reference.
   

3. More space should be there between the image and the info paragraph, see the image below for reference.
   

4. Right now the font here is not correct so need to change the font style. Also, the pink heading here should be bigger in size.
   

5. The RDS logo is not centered in the mobile view.
   

Fix the above mentioned issues referring to this Figma design: https://www.figma.com/file/OBKehkbowYSTE7xAgsRx2m/Welcome-Page?node-id=0%3A1
